How hard/$$$ to replace furling main with a proper battened one?
Hi, I am considering buying a 20 year old 45ft cruising cat. The main turnoff is the sailplan -- it has a lame small furling main for its size and weight.
The plan is to sail it up the (US) West Coast in Spring/Summer 2011, then Transpac to SE Asia, then on to Europe around the Cape of Good Hope (or Cape Horn if feeling brave).
Question 1: How hard/costly is it to replace the main with a proper fully battened square-toppish one? Can use the same mast?
Question 2: What is the approximate performance hit from the furling main, compared to a properly shaped sail? Are there polar plots for the boats >35ft with furling vs battened sails?
I am a newb here, so please feel free to trample on my feelings like others have done troughout my life.
