vang requirements

Hi again,

The last bit of equipment yet to be attached on our DSI (circa 1963) is the boom vang.

Problem is the mast is just under 22 foot and it is (at that length is HAS to be) stepped on the cuddy top. While I can get the necessary (according to the vang I bought from D&R Marine) 22 inches on the boom to drill the first hole for the vang plate, there is only 17-18" of mast from cuddy to bottom of boom. That will definitely not allow for a 45 degree angle of vang to mast. It will have to be maybe half of that. Plus, the lower section of the mast is taken up by halyards & fittings so that they will interfere with the vang when the boom is not closed-hauled.

So, what is the minimum acceptable angle for the vang? And, how can the fittings and halyards (made fast) be avoided?

Good Luck! (I'm thinking of simply not using the vang at all.) Please don't tell me I need a new (longer) mast!

interference and angle

The interference with othe rigging will be minimal and yes the angle has to change slightly to a somewhat shallower angle but the loads on this rig are very well within the capability of this vang. I have pictures of my set up which shows exactly the problems you are foreseeing, but they have not been problems in actuality.

Send me an e-mail at roger02 att mts dott net and I will send you pictures of my set up and you can see for yourself before installing.
