Which facts are we refering to? There has been a lot of opinion expressed, but
no factual support - unless I've missed something, the works of Marchaj,
Bethwaite etc apply equally to Proas do they not?

Fritz notes on his site:
- no need to reef or change sails up to 8 bft - beating - 10 running
- to be safe from any breaking freak wave or gust

in relation to his current project

- can we have some details of how you've managed to design sails that operate
across these sorts of ranges?
