Harken Vang-Master
The optimal angle of the vang is 45 degrees. The lower the vang mast fitting can be on the mast, the less load on the fittings
and spars.
IMPORTANT! Vang angles that are more or less than 45 degrees will reduce the effectiveness of the vang and load fittings.
Use the main halyard to hold the boom horizontal and check the length and locations. Refer to the stroke length and plan on
setting the vang up so the sailing length is midway or little less than half way. Hold the Vang-Master in place at half stroke
and check the angle to see if it is close to 45 degrees. If it is not, you may need a shorter or longer vang. With boom parallel
with the waterline, the vang should be set as close to a 45 degree angle
as possible to give the best performance through its range of motion.
If you have existing fittings, check the fit of the Vang-Master fork fittings and
also check for good rotation.

block and tackle (sold separately).
Use the main halyard to hold the boom horizontal.
Installing new mast fitting
- Check fit of vang gooseneck to be sure it seats flat on the aft sides of the mast. Be sure to
mount the fitting right side up. If using an existing vang gooseneck, check to make sure the vang can angle into position
and rotate correctly.
Mark holes and use a center punch. Mount fitting using SS rivets or drill and tap method.
Installing new boom fitting
- Check to see if the boom fitting has a fore-aft orientation; be sure to mount the fitting correctly.
If using an existing mast fitting, check to make sure the vang can angle into position and rotate correctly. Hold the boom up
so that it is at about mid-stroke or a little less. Check the vang angle to make sure it is about 45 degrees. Hold or clamp the
fitting in place and mark and center punch.
