Spinaker crane details

[Brion Toss]

Hello,
Even if the old crane is stoutly enough connected, which seems doubtful, it sounds like it is definitely old school, and not the best you could do. We often fabricate new cranes, which are made of plate aluminum, usually with a vertical stiffening rib. These angle well forward and to starboard, so the halyard block will clear the jibstay on both tacks, and have a good lead to deck. The plate angles upwards, and has a U-bolt bail at its end. The idea is that the halyard vector is split evenly when the sail is up.
If we had a masthead pattern, we could make a bail like this for you.
Fair leads,
Brion Toss
