Last week I decided to build a whole new support system for my jin pole that would include snap clips at the four cable attachment points. I fabricated a nice pretty new system and made all the support lines exactly the same length as the old ones that had been bolt and shackle secured. oops ! if you do this, then there won't be enough slack in the lines to hook them in place on the mast and deck, due to the shape of the hooks. if the cables were made long enough to do so, then they would be very slack once they're hooked up. my solution was to build yet another cable support system, with the mast attachment point secured with a bolt through the mast instead of using the snaps there. just something to consider if you use similar snaps. the up side for me as a trailer sailor is that it should save 10 minutes or so, at both set up and break down. 20 more minutes of sailing time. yaaaa .It also wouldn't be that difficult to add a quick clip where the leverage system attaches to the deck so the whole thing could be easily removed - which is would be the AL bar plus line plus blocks plus quick connects.
