mastrom quality control allows him to make

285 lbs = 129.105 kg platform within a margin of no more than 0.1% = 0.129 kg = 129 gram or the equivalent of 1 and a halve ronston smart ratchet blocks (the small kind) ? The pre carbo ratchmatic Harken ratchets were 142 grams per single block.

I think this to be a really strong claim. Halve of a plastic coffee cup with resin weights the same 120 grams if not more.

If you spread that out of two hulls of about 15 - 17 sq.mtr. overall surface you would add a film of only 42 micrometers = 1/600 of an inch.

And the funny part is that people can easily differ by some 5-10 kg's per person or 50 - 100 times the margin that Mastrom gives his boats. What is the use ? That is a whole lot of accuracy for nothing.

Better still is one of the sailors decided to take a cup of coffee for the race, as Mitch did at the 2004 F18 worlds, than that crew would allready by 2 times the marstrom margin overweight. No wonder Mitch finished 15th in that race. (joke). A pair of sunglasses weight 100 grams or more
