Thanks for that quick answer! I will certainly confirm everything with a measurer before building anything but your help will allow me to at least start thinking about it

The reason I asked some of these question came after reading

The description of the foils say:

"The jibing daggerboards work as they are supposed to do and lead to very good pointing angles. In choppy conditions the hulls pierce the waves, and the boat does very little pitching, thus leading to stable flow in the upper part of the main sail. When reaching the hulls are fully planning. Lift is provided by the flat underwater bow section and the leeward daggerboard - mounted at an inward angle of 10 degrees relative to the hull - and is sufficient to lift the leeward bow about 15 to 20 cm out of the water!!

Your interpretation of the rules are what I tough but this model seem to go differently, anyone have an explanation for that? A gybing board at 10 degs inboard on a boat that is canted can make an interesting lifting foil and if allowed this is a possibility that I would like to develop
