I'm wondering because I'm tossing up which mast to get, the luff on the Ezzy is 420 and I want to get a 430 mast (to fit another sail as well).
The website says that a 430 is the second recommended choice, so it should work, but I'm wondering if it means you have 10 cm of bare mast kicking around your toes.
Dave Ezzy made a feature of that pully. He took delight in pointing out that the other brand's pully details were crap because they don't separate the pulleys and its possible for the rope to jump from one sheave to the next. So he put a fence between all of his sheaves. Little did he realize that that particular feature is key to loop and go down-haul threading the dork.
