I have a Bristol 27. It was originally sold with a roller furling boom. It is common to find these boats with the boom replaced (for slab reefing). This is the case on my boat. However, the boom is only a few inches longer than the foot of the main sail. I don't have enough room to tighten the foot of the sail. What would be the cheapest way to fix this? Buy a new boom? Buy a new main (it is in reasonable shape)? MacGyver something to extend the boom? Ideas?
