Trapeze required for Xenon
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
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.
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?
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
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 has 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.
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
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

Parts of a Sail

Where should the Telltails go?
After a few months of sailing I have now mastered the ability to look up at my sails and make a vague judgement as to their worth. Having spotted the telltales I felt it was the next thing to master in my quest to beat the Lasers.
Once you have the jib trimmed correctly, you can start steering the boat, using the telltales as guides. If the outside telltale "piddles," this means the sail is overtrimmed for the direction of the wind on the boat. You don't want to let the sail out, so you must head up. This, in effect, retrims the sails, except instead of bringing the sails in, you "brought the whole boat in."
If the inside telltale piddles constantly, or if the sail luffs (actual luffing, or just an inversion at the front edge of the sail), the jib is undertrimmed. You don't want to crank in more on the sheet, so you must retrim by bearing off.
Your goal is to make the outside tale flow straight back and the inside tale "lift" occasionally, meaning some air is getting to it, but not all the time. If you don't know how often the inside tale should be lifting, err on the side of too often. It's better to have too much air flowing along the inside edge of the sail, than not enough.
So Lasers, with this and the Roll Tack, you had better watch out.
The next intreguing issue about the sails is to understand what the telltales on the leech-edge of the mainsail are meant to do...
