1-Can the boards and rudder be inclined either inboard or outboard or they need to be perfectly vertical in relation to the hull?

2-If need to be vertical to the hull, can te hull be inclined in relation to the vertical of the boat ?

3-Is it possible to have gybing or otherwise orienatable board?

1. they need to pass through the top and bottom centreline of the hull.
2. yes
3. yes

4-Does this mean that each hulls need to have the same appendages or that the section of appendage must be symmetrical ?

5-Does one hull need to have both of it's side identical?


4. each appendage (rudder or foils) must be symmetrical around its own centreline.
5. I don't think so contact your local measurer for confirmation.

6-Is it against the spirit of the rules to gain vertical lift by other way than hull forms?


I'm guessing yes.

So epoxy is allowed when joining wood but not for laminating fiberglass, am I right? What about covering wood with light fiberglass?


I think you could use epoxy when covering wood but again would consult a measurer before committing funds.
