Whenever you do a mistake on the early stage of building a boat you most likly going to regret it for a long time!!.
This is our case :
we are building a 45' wooden fishing/pleasure boat using greenheart (for keel & bottom planking) white ceder (for ribs& ) and silver balli (topside planking & deck).
we do not plan for the prop shaft hole while we was layng the keel made of several plank of greenheart (very hard wood) 7" thick and 7" wide and now we facing the trouble of bore an hole 2,5" in dia. long about 14' passing with an angle trough the keel!
We think about few different solution but none are very convincing and we are in serious need of professional advice.
Tanks to anyone that cud help.
