I love my jacks
Walter -I added lazy jacks this season and won't sail without them again unless on a racy boat with lots of crew to handle to main. The ability to drop the main by releasing the halyard and forgetting about while moving on to dealing with other issues is invaluable.I have a full batten main and don't have any meaningful problems with catching the sail. You just have to be a touch careful. I'd say the convenience more that outweighs the hassel.My jack are my own design consisting of two cheek blocks on the mast. A line runs from the cleats at the mast winch area up through each of the cheek blocks and terminates at the eye on a bullet block. The height of the bullet blocks is controlled by cleats at the mast. Another line, spliced to be continuous, run through a pad eye on the bottom of the boom at about 2/3 of the distance to the black band up through one bullet block, down under the boom forward where it is not attached to anything, back through the other bullet block and then through the pad eye. Works a treat.When I want to, I can realease the cleats at the mast, lower the bullet blocks and pull the whole mess out of the way - never done it though. Racing, cruising, reefing, unreefing - never had an issue.I won't go back.Justin - O'day Owners' Web
