RE: severne sails tack pully?
my mast base is a rdm carbon radz hawaii with the pull axel running across the board, the same way as the sail. the sail is a 06 model. the base pully system is however a 4 pully system, though I thread it to match the 3 pully sail block. I have done this in the past with other sail with out problems. though the severne is a different thing. personally I wish that sail makers wouldnt sew in all these different pullys as when you change sail brands you seem to have to change every thing else these days as well?
