The sprit will be a custom job done on deck. it will slid out and be pinned in position. My friend is a structural engineer specializing in aluminum fabrications and welding and he did a fabulous job on his sprit but that was a Fraser 30. He will make it for me at cost.
There will be a bob stay to prevent twisting especially if I go to a code Zero as well.
but I will be able to retract it and remove it for OD racing.
I will just do a normal launch and dispense with the furler. that's more for the genakers then the big A sails.
I am waiting to see the size of Sail to select the sheave to suit the load on it.
But I will just cut a new slot and insert the new sheave. no big deal.
