Any of you out there ideas on how I can proceed to fit foils (going for simple here so the foils will be straight) to an already build Mini40. my trimaran is an old French design Cobra which was inspired from the full size orma 60 but suffers from volume at the forward section of the floats. So the sole purpose of these foils is to reduce the nose diving and make the boat a bit easier to sail.

I was thinking to put them at 30d of angle how can find the position in the float to drill a hole at the top side and the bottom side for the tube through the float ?

Disable have you done something like this before ?
