Converting to double-line reefing
I would like to convert my very conventional system with two reef downhauls at the clew, cleated to the boom, and a hook at the tack, to a two-line per reef system (so I'd have 4 lines altogether for my two reefs) with all the lines brought back to the cockpit.
I have bought a 4 way rope clutch, and 4-way deck foot block. I'll need 4 stand up blocks for the deck too. Maybe a small winch will be needed?
The aft end of the boom has two cheek blocks in use already for the reef clew lines so I'll continue to use those.
1) I'm thinking of adding a double block to the underneath of the boom for the two clew lines. What's the best way of attaching this block to the boom? Use a bail? It'll need to be strong.
2) I can add two bullseyes to the mast for the tack lines. I will need a way of tying the two tack lines to the boom, then they get routed up through the tack cringles, back down to the bullseyes on the boom. How do I tie the lines to the boom? A bail again?
I'm trying to design the whole system to at least 1000lb working load. (180sq ft main)
If anyone has experience of this conversion, parts they liked, things to watch out for, advice in general, I'd be very interested to hear.
