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.

Where should the Telltails go?

It is some time since I completed my RYA 1 & 2 dinghy sailing course. It is on these courses that you learn and prompty forget what things like the telltales should be doing to get you going as fast as possible. To prove my point, when last out on the River Colne, just short of Bateman Tower, even the Bar Man, my experienced crew could not remember.

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...
