Rusty,

You should also be aware, that if you are intending on some serious racing, that the shape and size of the foils (daggerboards) are dictated by class rules. You can do some fine tuning of the foil but major changes, or having a slimmer set made, will probably not be "class legal". In this respect, it will be to your advantage to fix the trunk in the hull as opposed to modifying the board. That being said, I seriously doubt that anyone would every protest you because one daggerboard was modified in this manner - but the potential is there.
