Kevin:

We have a factory installed Hoyt Jib Boom on our Alerion Express 28. It's the nuts for single-handed sailing!!!
  • It allows the boat to point higher than with a regular jib.
  • It's smaller than a regular jib.
  • If you're flying a smallish (135%) Genoa and have roller furling, you should be able to use the jib boom in an emergency/unexpected increase in wind speed.
  • With ours, the weight of the boom doesn't allow running wung out in wind speeds less than 10-12kts (we don't have the optional extender/preventer).
Good luck!!!

This image shows why the pivot is moved back from the stay. It allows the boom to move out more before hitting the pulpit.

Your installation looks pretty simple. What did you use for the pivot and swivel?
Thanks

Just a bolt some washers and a "U" bracket.

At first I used a 2x3 attached to the tack and clue but that would not let me sheet out far because of the pulpit.

I made the pivot and moved it back about 18 inches.

I replaced the wood spar with the alum. one since I needed a gin pole to step the mast anyway. The pole is 1 1/2 inch by 1/8 thick alum. tubing.

Thank you
Did you provide some type of backing under the deck to keep the bolt from pulling through

Just a large washer.

I think the most load is compression, kinna like a wisker pole.
