Racing against an RS400

Here's another top-tip from the Topper Xenon dinghy racing scene.

We all know that on a run with the asymmetric spinnaker, you are not going to reach warp speed. What you need to do is play the angles and make a judgement as to whether it is best going the shortest distance at the slower speed or longer at the faster speed.

When racing against an RS400 you might think it is clever to play the angles go for the longer distance and greater speed i.e. do exactly what the RS400 in front appears to be doing and following their gibes with the spinnaker up.  Be warned, the RS400 has an evolutionary bowsprit that can be "rocked" to windward, allowing the RS400 to demonstrate breathtaking speed at virtually any downwind angle.

Pic - Tacking last weekend (thank's Fred in the safety boat)

This means you've got no chance of beating them at the angles game in a Topper Xenon and you need to focus on sailing to eat them on handicap.

Club Handicaps & Bostock Cup

To track and record my sailing progress, I have decided to publish the race results and how I have performed against handicap. I will advise that this is purely for my own reference and interest.

I have used the Results Worksheet which is published on the RYA website and build by the Portsmouth Yardstick Advisory Committee. If you like me are interested in statistics it provides fascinating results.

Standard Corrected Handicap (SCH)
The way it works is as follows....

For any given race, there will be an unknown theoretical ‘best possible’ corrected time that could be achieved by a boat sailing perfectly, tacking on the right wind shifts, avoiding adverse currents, etc. In practice boats are not perfect and their crews make mistakes that cause them to sail slower than this optimum. The resultant distribution of corrected times across a fleet will typically be ‘skewed’ since it is easier to make mistakes than to avoid them. A few boats may come close to the theoretical achievable time, some will make an average number of mistakes & there will be a diminishing tail of slower boats making increasing numbers of errors. Performance assessment requires a comparison standard against which to measure each boat. If this standard is simply the average of all corrected times in a skewed distribution, it will be weighted towards the poor performance end and the majority of boats will appear to have sailed better than ‘average’, distorting the assessment. The performance standard is defined instead as the corrected time achieved by the largest group of boats; that is the peak or ‘mode’ of the distribution. Boats that achieved this Standard Corrected Time (SCT) will have sailed ‘to handicap’.

Click on image for more detail

The YR2 procedure allows for the typical 'skewed' distribution in calculating the SCT. The average of corrected times for the top two thirds of the PY, SY & RN boats in the race gives the Average Corrected Time (ACT). ACT+5%, corresponding to the statistically average performer relative to handicap two thirds down the fleet, defines the 'poor performance' limit. The corrected times of all PY, SY & RN boats faster than ACT+5% are then averaged to give the SCT for the race. This new group of boats may be the same as the original two thirds or more or less, depending on the performance distribution in each race. The elapsed time for each boat is divided by the SCT and multiplied by 1000 to give its 'achieved performance'. Corrected times worse than ACT+5% are defined as 'poor' and should be excluded in calculating a boat's average performance for handicap assessment.

PY Handicaps
The handicaps I have used are those published by the RYA. The one assumption I have made in my calculations is that the handicaps of the Wivenhoe Ones are well established and can be included in SCT calculations.

Handicaps and statistics are very interesting things. The Xenon crossed the finish line second, came 8th out of the club handicaps and 4th in the RYA handicaps (2.3% above par on today's sail).

If you spot any obvious errors let me know.

How Fast Does a Topper Xenon go?

Now that I am in my second season of racing the Topper Xenon, I am starting to get interested in just how fast we might be going!

There is a formula for calculating the maximum hull speed of a boat which is....



HSPD = maximum hull speed in knots
LWL = hull length in feet at waterline

I will need to make a few minor assuptions - the length of the Topper Xenon is 4.5m and this will be assumed to be the LWL which in feet = 14.764ft


HSPD therefore = 4.37 knots (8.1kph or 5.02 mph)


Now here's the real key thing to understand about how you are going to win races. You have got to learn to plane because when you do the formula goes out of the window.

When to use the Spinnaker

The Season has started again and I am back at the helm with the Barman crewing!

To start the 2010 Season, here's a few lessons learned about today's 'Can Race' at Wivenhoe Sailing Club.

The spinnaker on the Topper Xenon is both a race winner and race looser. Depending on your level of experience it could go either way but I reckon if you can use it you should and there is no other way of getting experience than trying it out.

Today's race adventure started as we headed south down the Colne and I got the Barman to put the spinnaker up. Yes we had it rigged right for once and it went up really well. I now realise we were on a bit too much of a reach to control it and we overpowered. This is when the fun started and the Barman was hanging on the side of the boat with me thinking yikes where is the safety boat....

Can Race at Wivenhoe Sailing Club
At Wivenhoe SC, this means you have to go round every buoy on the course, and with today's wind we went up to Rat Island opposite Brightlingsea - a long course.

Lessons Learned for Spinnaker
      • The Topper Xenon's spinnaker is huge so if the winds aren't light and you are not on a broad reach it is going to overpower you.
      • Don't put it up if it is blowing F4-5 (just yet anyhow!).
      • If you are starting to loose it, get over the side asap and on that centre board (easier for the crew!).
      • If your crew goes in the water and you are left onboard try to..
        • drop the spinnaker
        • point to wind
        • lower the centre board fully
        • furl the jib
        • haul in spinnaker
        • haul in crew
        • avoid ditching as it will be a nightmare righting it with the spinnaker in the water and the wind.
      • Keep your eye on the more experienced crews to see what they are doing.

Sailing with a Cunningham

In an earlier post I highlighted that the Topper Xenon has a cunningham in oppose to a downhaul. This is not just another rope and is extremely useful when racing and of course sailing in general.  If you have a Xenon you have got to learn how to use it. In our last race the Barman and I noticed a significant improvement.

The cunningham adjusts the tension in the luff extremely quickly and easily. By hauling it in or easing the line, the tension in the luff can be changed, thereby shifting the point of maximum draft forward or aft so as to optimize the sail shape.



I have found the greatest impact is when you are trying to point upwind on a close haul. If the cunningham tension is on, you don't point very high.

This bit from the Xenon manual starts to now make a bit more sense....

For a medium wind (crew sitting out hard, but able to sheet the mainsail to the centreline) you should be able to use maximum power. Use very little or no cunningham. The outhaul should be set so that there is about a 3in (7-8cm) gap between mainsail foot and boom at the point of maximum chord. Try to keep the boom on the centreline, provided that the boat remains flat.


The jib can be eased about 1-2in (5-10cm) from maximum tightness for optimum performance. As the wind increases, reduce the power in the mainsail by pulling down on the cunningham progressively until the boat feels comfortable and balanced again. If you have tell tales on the leech, use enough gnav to keep them flying.

For very windy conditions flatten the main by tightening the outhaul, tensioning the cunningham further (with a fully-battened sail this has the effect of flattening the sail without pulling the fullness forward and can therefore be used much more than with a conventional mainsail). Sit out hard and sail free.

In light airs, use little or no gnav to allow the leech to open.

Man Sailing and Gunships

Last Sunday's sailing was tough and I have classed it as proper man sailing - apologies to all women sailors!


The Barman and I had the boat going to Brightlingsea and once the estuary opened up we got the Xenon going like a speedboat. Now the forecast said it was going to be a managable F4 wind which was perfect; unfortunately it was much stronger. On return and checking the Brightlingsea Sailing Club website (see above) we had been out in a F6 gusting +30 knots.

When we started to plane off Brightlingsea, I have to admit I was starting to get a little scared, not necessarily because of the wind but the size of the waves that we started to hit and the fast approaching shoreline directly ahead of us. To add to the man-sailing day an Apache AH64 gunship flew overhead as we were bombing along looking cool.


Now the real challenge was getting 8km back up river and maintaining control (i.e. not capsizing); as a result my tacks became real girly (I've made my apologies already).

Problems came when we found a mud bank opposite Arlesford Creek and came to a sharp halt; I had managed to get the nose pointing back down wind before both centre board and the rudder had to come up.  We then found ourselves on a very difficult to control run in a foot of water, all lines on the rudder snapped again(!) and the tiller looked like it was going to break as I tried to keep us straight - it started not to be so much fun. I wasn't able to get the rudder back down properly so we had to limp the last 4km back in to Wivenhoe. All in all an exciting and challenging sail.

Update on dress in the boat - it is time for wetsuits.

Topper Xenon and Endeavour Championships

I could hardly own a Topper Xenon and not make mention of the RCYC Endeavour Championship.

Well, here goes - The RCYC Endeavour Championship is a unique event in the UK dinghy sailing world, recognised by the RYA as the pinnacle of that year's dinghy sailing achievements which will hail a "Champion of Champions". Held on the tidal waters of the rivers Crouch and Roach every October, it's an invitation only three day event, with the guest-list hand-picked from National Champions of selected fleets.
Once the year-long preparations for the event are complete, the Topper pantechnicon arrives in Burnham containing thirty 'box-fresh' Xenons and the Topper technicians (dogs-bodies) who prepare the boats for the competitors. The Friday is a training day of Olympic standards when the entrants get the chance to familiarise themselves with the dinghy that may help to them to realise their dream "...over the hallowed waters of the Rivers Crouch and Roach". The Saturday and Sunday is a relentless progression of eight races, whatever the weather...

So I wait for my invitation and see if I am able to swap Xenons for a slightly newer model...October right? I'll save the date!

So why a Topper Xenon for this event?.......the continuing choice of the Xenon for the Endeavour Championships solves two problems at a stroke. Previous entrants considered that the RS400 (the previous boat) was a handful for lighter crews and there were occasional difficulties with availability. The Xenon's crew weight is pitched between 18 and 24 stone and Topper continues to supply all the boats so entrants need only arrive in the dinghy park to find a boat awaiting them (cheers easy).

hmmm.... at this point all I will say is my crew and I need to loose some weight...picture above is from http://rodtinsley.co.uk/ and is of Steve Tylecote and Toby Lewis who won in 2007. Looks just like me and the Barman.

ps. look how flat they have the boat

Topper Xenon's Cunningham not Downhaul

Sailing parlance can be very confusing at times as the same thing onboard can be called a number of different names (e.g. a kicker, boom vang, gnav, thingme giggy etc). When learning to sail this doesn't help your speedy understanding of the technicalities of sail setting. Another example is the downhaul; on the Topper Xenon which is called a cunningham!

The cunningham differs from a typical downhaul in the way that it attaches to the sail. The system usually consists of a line which is secured at one end to the mast or boom below the foot of the mainsail. It is then passed through a cringle in the luff of the sail near the foot, but above the tack, and then led down on the other side to a fitting on the mast or boom or on deck.

It is named after its inventor, Briggs Swift Cunningham II, a victorious America Cup skipper, who was a yacht builder and sailor, as well as being a racecar enthusiast, driver, team owner, and racecar owner and builder. The yacht, Columbia, was led to victory by Cunningham in the America Cup competition of 1958. Briggs was inducted into the America Cup Hall of Fame in 1993. He is also in the international and American motorsports halls of fame and when innovating devices for yachting, called on the specialized talents of automobile racing friends to solve problems such as metal stress and selection.

There you go!

Hiking out

So in principal we all agree that to balance the boat is important especially when on a close haul...centre board stays deep keeping the boat pointing upwind as much as possible and it does not act as a rudder trying to turn the boat...right!!

Also, we agree that the proper technique for hiking is legs straight and back slightly bent to get the weight out with as little effort as possible.....this works for me at the helm as the Topper Xenon does not have any cosy area for the helm to sit and it's great to stretch the legs....

What I have found in my 1x season as a skipper/helmsman is the tendancy of some new crews not to not want to lean over the edge of the boat and get their weight out but a preference to lie across the middle (i.e. feet against one side of the boat and head at other which is possible in a Xenon as it is about 2m wide).

BALANCE THE BOAT they'll hear me say.

Anyway here is an excellent article on what I am on about   http://www.uiowa.edu/~sail/skills/racing_basics/chap4.shtml @ Mark Johnson

Capsizing Drills in a Topper Xenon

It happened again last weekend with my Father as we sailed up the River Colne...the shame...!

We went over on a tack, which was interesting as the dinghy has come near to doing this before with other novice crew. I am beginning to have a theory as to how this might happen - beyond blaming myself.

Firstly the cleats that hold the jib sheets on the Topper Xenon often out-fox novice crew who I have seen have difficulty releasing them. When on a close haul the jib is set very tight and so is the cleat holding the jib-sheet. Coming round on a close haul tack, if the sheet is not released properly the nose will continue to pull round and instead of being on a close haul (opposite tack) you will find yourself coming on to on a beam reach. Obviously with a tight main sail + slow speed over you go. So, lessons to be learned are as follows...
  • Teaching your crew how to operate the cleats and warning them of consequences if they get it wrong.
  • Helmsmen don't be lazy and be ready to let the main sail go if things go wrong on the tack (i.e. take it off the cleat).
Finally, make sure you explain in detail what you want the crew to do when you go over. Novice crew have a tendency not to want to go in the water (quite understandable really), but the Topper Xenon floats very high on its side and with the crew trying to clamber desperately up the inside, the boat is inclined to turtle making it harder to right.
  • Tell them to get in the water and swim to the back to hang on to the toe straps).
  • Always be nice to the Romford Navy, speedboats and barges as you may need their help one day.

Brightlingsea One Design

My lack of original content and poor prose show up badly when compared to professionals like Dylan Winter. I came across another video he did as it had some Topper Xenons in sailing at Brightlingsea. Anyway it gives a great impression of what it's like where the Colne River opens up and what they look like underway.

The Brightlingsea One Design (BOD) is a big feature of this video and is similar to the Wivenhoe One Design (WOD) but bigger!

Anyway - here is how the pros do their video blogs.....

Topper Xenon Launching at Wivenhoe

I finally have created some content of my own. Here is my father and I taking the Xenon out for his first sail on her from Wivenhoe to Colchester and back up the River Colne. I chose what I thought was a safe passage, but yes we did have an incident on the way!!...more later.

Forgive the music, I was under a bit of time pressure to get this 'out there'

Xenon Handicap and others

In a sop to the search engines I am going to put in a post that covers the PY Handicaps of the Topper Xenon and others who I race against.....


Topper Zenon - 1070 (with Trapeze??)

Laser - 1078

Wayfarer - 1099

Topaz - 1212

Mirror - 1365

Wivenhoe One Design - ????

A list of the most popular fleet boats can be found here thanks to the RYA. What is not clear to me is how the Trapeze option impacts the handicap. I think that the handicap above is with the Trapeze operating. I don't have a harness yet so I believe that I am probably getting penalised with a too high a handicap at club races.....hmmm very interesting I must find out more as this could make some big changes to my race results..!

Dinghy Racing - Long Distance Race

We had the long distance dinghy race last weekend; the Barman my usual crew was not able to make it due to work commitments but his very experienced father volunteered to replace him; Father of the Barman now known as FB.

I thought it was going to be a walk-over but 4 other boats did eventually enter into the long-distance dinghy race. End result we came 3rd and that includes with the handicap. The 2 boats we left way way back were a Wivenhoe One and a Mirror.

What was slightly disappointing was the margin by which we were beaten by another Wivenhoe One and a pesky Laser. We did expect to do much better and were slightly disappointed. FB did have some good sailing tips. The issue we have is that there is very little knowledge within the club about how to sail a boat like the Topper Xenon.

Being the observant helmsman and having had a few crew on board, I have noticed a couple of things where the manual differs (see http://zambezishark.blogspot.com/2009/07/how-to-sail-topper-xenon.html) from the habits of experienced crew used to sailing other types of boat.

These are (when going upwind)
  • tension tight on jib
  • lots tension on cunningham

I also notice that there are a number of opinions as to where the telltales should go. Some say both fly horizontally across, others having the inside flicking upwards (as per http://zambezishark.blogspot.com/2009/07/where-should-telltails-go.html)

We were a new team and areas that we could have improved were around handling of the spinnaker. We struggled at times and perhaps should have borne away from a straight run to build up speed on more of a reach angle. This will come with practice I am sure. What is not certain either is whether the jib should furl when the spinnaker is up? Marketing pictures from Topper all show it up - I'll have to check some more neutral snaps but I reckon the jib can stay up.

Finally disappointing as it was, there are a whole host of other reasons why we did not do as well...

  • other helmsman was a previous national champion on Enterprises (apparently)
  • there is a tidal channel through the course of River Colne which I don't know very well yet
  • we grounded on the mud
  • my first season
  • luck

Anyway if there are other sailors of Topper Xenons please add your top tips in the comments section below.

Laser Vago Planning

There is a dire lack of videos out there of what a Topper Xenon looks like when it is planning. To give a clue of how the Barman and I looked (albeit briefly) before we capsized I found this video with a reasonably similar looking boat. It does take a bit of skill to do this and they are not out for their first sail.

The Xenon is slightly larger and I believe has a slightly lower handicap (just) - it starts getting picky when you try to decide whether it is with or without trapeze.

Have a look....

Trapeze required for Xenon

I have being mulling over how we came to capsize the Xenon and how we could have avoided it - thoughts are with me still because I am only just loosing the stiffness and bruises I developed last Sunday.

Given that from the weather station records it was blowing F5/F6, and we, without a care in the World, popped the spinnaker up on a dinghy, I think we were pushing it. It was a very gentle blow over and it makes me think that we might have been able to avoid it if The Bar Man, my loyal crewman, had had a harness for the trapeze kit.

If anyone knows of one going, let me know!

How to Capsize a Topper Xenon

I finally capsized the Topper Xenon with the Barman!

Today was a damn good outing - HW was at approx 4pm and we launched at about 2:45pm from Wivenhoe Sailing Club. May be it was a little ominous but I botched the start again - need to get the rudder down faster so I get control of the boat before we get blown into the mud in front of the club house. Knee deep in mud we had a second launch and were much more successful.

The pic above shows how good the wind was - we were out on the peaks. It's on days like this you need a warm-up program as you get a proper workout as the invisible hand (called the wind) flicks the sails with its finger randomly. At 3:45pm we were opposite Bateman's Tower at Brightlingsea (took about 50min - remember we had a botched start). Hmm seems we were averaging 6 m.p.h. which is not too bad - feels faster!

There were a couple of skiers about and oddly enough the RNLI were attending a boat on the east shore.

We had turned and were heading back when it all happened. We tried to line the boat up for a mega down-the-river-gybe with the spinnaker up all the way. We were just about on the plain as it was but this was going to be even faster - sadly not. Only a couple of minutes after we had the spinnaker up, we were over powered by the wind and into the Colne River we went - salty yum.


So we are in the water. Initially puffing because of the cold. All of a sudden the boat is massive - only our heads are above the water and the boat towers high-up floating on its side. We have to right her. I swim round the back and the dagger board is above my head at the top of my arms reach. I get both hands on. Kicking my feet and hauling myself up I get laid across feet still in the water. Nothing happens. Slowly it starts to move towards me and we shout at each other as it comes up straight. Sails up and wind blowing it starts to race off and blows over again. This time worse. The mast starts to sink and she begins to turtle. This is not good. Our arms are aching as we try to haul ourselves out of the water and right the boat. It starts again but blows over. We keep going and getting tired fast curse not going to the gym enough. A speedboat approaches and offers help. They haven't a clue what to do. We need to get the nose to the wind when we right her. A rope is tied to the front and it hauls the nose towards the wind. Another young guy pitches up in a speedboat but he is on his own and useless. We start again. Tired, it's getting harder and I understand how people get too exhausted to do anything. It works though and I try to get over the side. It's too difficult now and I go over the transom at the back instead. I bring down all the sails. The Barman needs hauling on board, he's tired out as well. We re-organise the sails. Thank the speedboat people and get on our way. We are knackered.
It's not over though as we have a few miles to do.

However this is when the good bit happens. All the time I thought I had been on the plain previously were mistaken. We were hurtling along when all of a sudden the boat lifted up above the water and we had a significant turn of speed - WOW it made it all worth it.

There are many lessons learned here - see my coming blog about gennakers (!) - but I would recommend if you are going to do daring things with dinghies and they are 10ft+ it is well worth getting a mast float. Next time I go out, I need to take the mast down and wash the top where it scooped mud from the bottom of the River Colne (meconium style [er....look it up]).

Why a Topper Xenon?

Press and reviews of the Topper Xenon often make referrence to its 'stylish looks' and this was repeated to me recently at the sailing club. I started a conversation about why I had originally bought the 'Zambezi Shark'.

Initially it was not on my radar what-so-ever. I had trained on a Wayfarer and had been using the sailing club's Toper Topaz. The Toper Topaz is a small boat and at the most is designed to take one adult and one child. This ruled it out of my selection criteria as I had visions of taking Mrs Hook out one day.

The Wayfarer was looking like a good option - it was very stable, reliable, kept its value and could fit at least 4 people in. I knew how it worked and everyone said what a good boat it was. There were a few niggles though. All the boats I saw 2nd hand had kept their value just a bit too much and for a boat 10+ years old prices were £1500++. I thought this was too much given the maintainence that I would potentially need to do. Also the matter of style started to come into it - the older Wayfarers, within the range of the boat-fund looked horrible. There were too many home made paint jobs.

Some might say that you shouldn't buy a good boat to start off with. I disagree. Buy the best you can. It's a sport that you have got to commit to. I had nightmare visions of buying a boat and growing out of it very quickly, wishing I had somethig better. If you are new to sailing and you know it is what you want to do, get the best you can so you can enjoy it more.

Having raced for a few months on theTopaz, I had another requirement and that was speed. The Wayfarer was well out of it now and after further research I went to check out a Topper Xenon. I would have looked at more boats, but it was so good looking that as soon as I saw it, it made me buy her. Considerations were...

  • Size
  • Speed
  • Cost
  • Looks

How to sail the Topper Xenon


Here is some useful information for me and my crew to remember when sailing the Zambezi Shark (aka Topper Xenon) - particularly the Barman, as we were definitely rusty during Friday evening's pursuit race er....or was it just me??
The aim this course is of course to beat those pesky Lasers. BTW everything below comes from the Topper manual so must be true..


Upwind
For a medium wind (crew sitting out hard, but able to sheet the mainsail to the centreline) you should be able to use maximum power. Use very little or no cunningham. The outhaul should be set so that there is about a 3in (7-8cm) gap between mainsail foot and boom at the point of maximum chord. Try to keep the boom on the centreline, provided that the boat remains flat.

The jib can be eased about 1-2in (5-10cm) from maximum tightness for optimum performance. As the wind increases, reduce the power in the mainsail by pulling down on the cunningham progressively until the boat feels comfortable and balanced again. If you have tell tales on the leech, use enough gnav to keep them flying.

For very windy conditions flatten the main by tightening the outhaul, tensioning the cunningham further (with a fully-battened sail this has the effect of flattening the sail without pulling the fullness forward and can therefore be used much more than with a conventional mainsail). Sit out hard and sail free.


In light airs, use little or no gnav to allow the leech to open.


Tacking
Be aware that with a fully-battened sail the power comes on very fast after the tack. Do not over steer with the rudder as you will find yourself on a reach. Do not sheet in hard immediately, with either main or jib, until the boat h
as picked up speed after the tack. Whenever the boat slows down it pays to ease sheets, bear off a couple of degrees and then oint up again once the boat has regained speed. In light winds, when about to tack, make sure that there is some gnav tension, as this will help the battens to flick across. Ease the sheet a few inches before tacking. A sharp pull when you reach the new tack will also help the battens across.


Downwind
With an asymmetric Spinnaker, large distances can be gained (and lost!) very quickly. It is essential to keep the boat traveling at the optimum speed and direction towards the next mark. This direction will vary according to the wind strength. In light airs, at displacement speeds, where sailing higher will not result in a great increase in speed, it pays to sail low towards the mark. In marginal planing conditions, sailing higher will allow the boat to plane and the consequent increase in speed help to offset the extra distance traveled. The boat can be sailed progressively lower as the wind strength increases.

Just when to sail high or low and at what precise angles will come only with experience, so keep practicing. The crew can have a better idea of the correct angle to sail by feeling the power in the spinnaker sheet. Allow the crew to call the pressure. Sail as low as possible, keeping the pressure on, unless there are overriding tactical considerations.

Gybing
An asymmetric Spinnaker is far easier to gybe than a conventional spinnaker and takes no longer than tacking. Ideally you should always gybe when the boat is traveling at maximum speed as there is less pressure on the sails. It therefore pays to gybe 'reachto- run'.

If you try to slow down and gybe 'run-to-run' the spinnaker pulls the top of the mast forward, making the boat unstable and less controllable. The additional air pressure will make the mainsail harder to pull across. So be positive and gybe smoothly and at speed.

In strong winds you will probably have borne off so that, although the apparent wind still shows a broad reach, you are in fact running directly before the true wind. If you then try to gybe through your normal angle you will gybe on to a reach and be overpowered! So in strong conditions remember to gybe through a smaller angle. As with tacking, apply some gnav tension and Cunningham when gybing in light airs to help the battens flick across.

Sailing and Fishing

I have been interested in the idea of fishing off the back of my Topper Xenon. I have however come to the conclusion that the style of dinghy makes it totally impracticable. Unlike a Wayfarer it is impossible to drop the main and wrap it up round the boom. Since I have a gnav and not a vang (American I know, should be called a kicker), when the main sail comes down, the boom does as well leaving the deck covered in sail and boom. The advantage however is that when the main sail is up, there is more room on deck. This might mean I am better off fishing whilst underway, perhaps some type of trawling with a line and spinner on the end, the sort of thing you see in the Pacific when line catching tuna - idle thoughts I know when in Essex.

Here's a chap called Blakdog who fishes on the Colne River; I'll keep an eye on to see if there is anything worth catching http://seaanglersnotebook.blogspot.com/2009/05/batemans-tower-brightlingsea-essex.html
