I am thinking of adding a boomvang to my Typhooon to increase performance in light winds [usual conditions in late spring on Long Island Sound] any suggestions or experience?
Please advise,

Re: Downwind performance

I also sail on Long Island Sound (eastern) and I have found that using my whisker pole on the genoa helps considerably especially on a wing-wing broad reach. I personally feel a run is dangerous especially in variable winds of the sound. Full keel boats do not sail particularly well downwind to begin with so the answer generally is a sail area problem rather than trim. My solution was an asymetrical spinnaker..once you get used to them they aren't a bad solution.
Just my humble opinion. Hope this helps.

Jack; Normally a boom vang is used to keep the boom from rising up and making the sail too full. The idea is in higher winds "the harder she blows, the flatter she goes..". The vang is tensioned in higher winds and slacked off in light air. The second use for a vang (block and tackle version) is used as a preventer for downwind perfromance. The use as a preventer obviously is to 'prevent' the boom from slamming around on a run in seas. By making the vang fast to a toerail or stanhion base midships will have the effect of preventing and if tensioned further will keep the sail flatter to avoid chaffing on the spreader.I am thinking of adding a boomvang to my Typhooon to increase performance in light winds [usual conditions in late spring on Long Island Sound] any suggestions or experience?

You have the right idea Jack....great for downwind as well as the more traditional use for flattening the main upwind. Place a bail on the boom and near the boot of the mast. Use at least a 3/1 purchase. The boom vang at the mast foot should have a swivel snap shackle release to move it out to a pad eye near the toe rail. The shackle at the boom bail can be fixed swivel if you like. This will flatten the main downwind (exposing more sail area to the wind) and also serve serve, not as a traditional boom vang but a "preventer" to protect against accidental goose wind jibes if you get off the wind a bit. Not only will the boom lift but will not accidently move to the other side. Great to controlling the funnel of wind into the fore sail as well to keep the clew out and filled.

Excellemt upgrade as noted below. I did the following: A padeye mounted on the aft surface of the mast. The washers and locknuts will slip into the slot below the halyard exit. West Marine sells a good tackle setup with snap shackles-It comes in 3 sizes, get the small one. For the location of the boom bail use a line to measure up from the padeye so that it forms about a 45 degree angle. A Shaeffer bail will fit the boom, but it must be bent a little bit. Tap the holes in the boom, and use ss scrws with some Loctite.
It will really help to flatten the sail going downwind, and if you add a hook, the tackle can also be used as a cunningham.
