Re: Keel
E.1.1 a ....a fin and a bulb.
a fin is singular so only 1 fin is allowed.
E.3.2 b.....shall not (3) have openings through which water could flow when in use.

Re: Redress...
Fix it. As some one who has been on the recieving end of this scenario (run down by windward boat on the start line) I think it is important to retain redress. Imagine the situation at a club level regatta, who would want to race against beginers? If they mess up you loose. Not a good scenario. I ju...

Re: What cord for sheeting and sail adjustment lines
Graham, It sounds like such a simple inocent question. But, the truth is, like so many other facets of sailing it is in a large part down to personal preference. The basic starting point is Dynema line as used by kite flyers so readilly available and cheap. Also has better holding power with bowsies...

I would have thought that the principal of HMS is to simulate a full fleet race In the full fleet EVERYONE who does not finish scores fleet +1, the point exactly. One could argue that the last boat would be 20th weather it DNF etc or not But this guy has not completed this race. Just because he did...

I agree with Ole on this. Racing in heats and series is not just about the one heat/race, it is about good preperation to be able to compete for an extended period. Take the example of the boat that gets promoted all the way to A fleet. If the boat can only last these 5 heats it would not win a seri...

The advantages of shareing
I have started yet another thread on this subject to give a different point of view. I have been racing and building IOM's for some time. I thought it great that someone came up with the idea of using the same rigs and keel. It allows me to design and build a more challenging hull (the design envelo...

I agree with the idea in principal. However I feel the actual rules will need a little more work. If a slit is cut into the sail it will need to be joined in some manner? For a conventional broad seam joint there are plenty of controls over seam width, number of seams etc etc, shouldn't these be inc...

Anders On the boat I use at the moment, which is the prototype for my own design, I have the antenna exit the top of the pot. Then it runs inside a tube, which leads aft, and up to clear the end of the boom at about 40deg. On the production model the rx will be placed behind the sheet post so the an...

I have one of each in 2 of my boats that have been running for over a year with the ocasional dunk in salt water and they both still work fine. (bet they don...
