And here's how you do it to build your own boom vang. It works real good, lasts a long time and costs a lot less. I built this one for my Precision 16 last summer and it is great. The parts that you will need are: Ronstan Model 186 Fiddle $15.99 Harken No. 245 Fiddle/V jam $18.29 2ea Ronstan RF180 light blk hngr $$3.59 optional 2ea Wichd #1432 keypin shackles $9.79 (I like the captive pin models rather than the cheaper stamped models that use the key-ring lock) Mount the hanger as close to the bottom of the mast as possible and place the one on the boom at the same distance out that the one on the mast is down below boom position. This gives a 45 degree angle for the line. Be sure to pre-drill the holes large enough because the stainless screws pop a head off in a jiffy when screwing them in. I always mount the pull block (vjam) at the lower end because that lets me pull back rather than down. For the line, I used a piece of the old halyard about 10 feet long. You will love it and you have done it yourself AND saved a few bucks. That is what this boating thing is all about... being able to do things yourself and innovate to get the result that you want. All of the prices above are from West Marine. Great folks and lots of help. take a look at the photos on the site below.
