There are several Texel measurements. Starting back in 2001 or 2002 up till now. The first weight was 108 kg and now we are at 127 kg. I seem to remember that we passed 115 kg along the way at some point.

I don't know which boat Marstrom sailed himself.

I think we can trust the Texel measurers to weight the ACTUAL weight of an M20. But then again you never know what happens behind the closed doors. Maybe the boats provided for measurement were weighted down to get a favourable handicap.



See my other post. Quick answer is "Not that much weight". Certainly not 10 kg. Don't forget that the guys owning the M20's aren't skimping on parts. They are not sailing with heavy duty dacron sails if that is what you are asking. All are sailing with modern pentex sails. It is also my experience that sails don't differ much in weight.

Marstrom is simply building these boats at a higher weight than he was in 2001/2002. 108 kg to 127 kg is a big difference; you don't get there (19 kg) with some heavier mainsheet blocks and stainless steel rigging. The difference is just way too big for that.




hummmaaah, this is a bit strong. It certainly doesn't kill the speed. If anything the speed difference is within 0 - 2 % = on a par with a bad tack. And then it also dependents on which tack you are sailing. Having the halyard on the windward side of the sail will hardly make a difference at all. Theory predicts that as well. One reason why to have the halyard on the starboard side of the boat !

We have heard all these claims before and still the spi boats are going strong.




Maybe. Weight spi = 1.2 kg weight snuffer ring + sock (on my boat) = 1.5 kg. Position ring and sock on my boat = on average 0.7 mtr in front of the mast. Net difference between the snail setup and snuffer setup = negigliable. The weight is too small to matter much in the big scheme of things and the difference in leverage (0.7 - 0.4 ?) is too small to result in a meaningful moment difference.
