Pepin, I'm not sure how the French measure their boats <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />but having measured your boat this afternoon and double checked it, Nick and I reckon its 5.003 metres long, ie 3mm over length and not 3 cm's. We measured both Nicks and mine as well and they all are about 2 - 4 mm over the 5.00m mark.

We also measured a latest version of the Stealth and its about 5mm under length ie 4.995 metre.

I have a possible theory on why you came to be 3cms over length, did you use the Dinghy Stores tape measure, it has an imperial measure on one side and a metric on the other, the imperial starts at Zero, the metric starts at 30mm, I'm not sure why but it does and I have seen this on similar tapes before. We just started from 1.00 metre to make absolutely sure.

So by my reckoning you can use a F16 sail and be totally compliant to fit within the rules,If your boat was one of the very early boats and not made by Stealth Marine, you may want to check the weight as they are right on the weight, perhaps even a kilo or two under. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />

From my understanding the earlier masts were slightly softer than the later masts, you may perhaps want to consider moving the diamonds slightly foward to compensate.

Hey you got a lot of boat for your money, I reckon you will be up to speed pretty quick as you used to get your old Nacra shifting pretty well. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
