I have submitted a request that the class allow an increase in the power ratio of the vang, and am starting this topic to see what others think of this idea.

I did not request a desired new power ratio, but left that open for discussion.
I think at least 12:1 would be desirable, and 16:1 would be very easy, because adding one cascade block to an existing 8:1 setup would create a 16:1 power ratio setup.

Quotes from the Class Rules:
1.1 The J/24 is a one design class created to fulfill the diverse needs of recreational sailors such as
cruising, one design racing, day sailing and handicap racing. These rules are intended to preserve
important design characteristics: ease of handling, low cost of ownership, safety, comfort, and the
one design nature of the boat.

3.5.4 Running Rigging
d) One kicking strap (vang) of synthetic rope of not less than 8mm diameter in a tackle not
exceeding 8:1 power ratio. A wire strop of not less than 4mm diameter or synthetic rope strop
of not less than 8mm and not more than 305mm in length may be used to connect the kicking
strap to the attachment bracket on the mast.

I think this change would increase safety and ease of handling (as stated in 1.1 above), and that adoption by any team would be optional, and could be done at very low cost.

I would be interested to hear what others think.

Thanks,

Understand the technical committee is recommending this rejected due to concern about breaking booms. Seems to be 2 issues here, how easy it is to get sufficient vang (which often has people sitting on booms/etc.) and what we experience where it is very difficult to release the vang, which is more of a safety issue. With respect to the 2nd, do folks have vang systems that are easy/simple to release that should be shared? Think ours is pretty standard with a downward facing cleat on the bottom of the whole setup, which is easy to apply from the rail, but difficult to release.
