Have an Anderson 12 self tailer mounted on the cabin
top at the cockpit
Originally had a non self tailing
winch on the boom on this boat and on my old boat. Found it was really fun reefing in anger with one hand cranking the winch and the other tailing. OOPS, forgot about the hand not holding me onto the cabin
top. If you mount the winch on the boom, mount it where you'll be able to crank it with the boom all the way out on either tack.
Boats with internal reefing booms usually mount the winch below the boom on the mast
if there is enough room to swing the handle. You can reef while kneeling and leaning against the mast that way.l With your wooden boom, would have to have blocks at the gooseneck to turn the lines down to the winch.
Get a self tailer for the reefing winch wherever you mount it, makes like a lot easier and safer.
