If a mast limit is set it should take account of the existing boats, i.e. set it to the length of the longest mast. The Stealth has 8.4m mast

<br>My comments on the weight carrying ability are that it seems to me that f16ht will end up with similar sail area to our Stealth R for which a crew weight of around 145kg is best. f16ht will be a foot wider that the Stealth so it should need less weight to keep it upright. <br><br>
