I shimmed mine with washers when I reinstalled it, even so it still thumps if the waves are large enough as the cable looses tension.

tnc, Good to see you back in the water, if your girlfrend is sailing with you, I would say she's a keeper. Better luck sailing.

Hmm, I've heard this before, but thought it was a back and forth thump, ie the bow raises on a wave, swing keep swings a little aft, then bow comes down, keel goes forward and thump.

My boat had the keep pin totally redone just before I bought it ( saw the receipts from a good local marina ), so I *hope* its not going side to side. On mine, it was definitely correlated with the bow coming down after a good lift.

Don't some swing keels seem to have a mechanism to lock the keel down?

i did some investigating today... when i re installed my new keel i glassed over the large hole above/aft of the pin that the nylon rod came through. i did this because on the inside at the area that the flange mounted to was rotten. it was bad enough that i know that it would never have sealed back up. i assumed that this nylon pin was designed to lock the keel down so i didnt think that i would need it. however i think that maybe the nylon rod is used to push on the side of the keel to take up any slack??? my original keel never made a noise when the nylon rod was in place...

today i cut an 8 inch circle out of a 1/2" thick nylon sheet. then drilled a 5/8 hole in the center. cut a 5/8" slot from the edge to the center hole, leaving just enough material around the hole so that i can smack it with a hammer and get it to "click" onto the keel pin. was planning on using this as a shim to get the keel to tighten up a bit, but the 1/2" shim was too much/too thick. tomorrow i'm gonna try to find some thinner material and try again...

Yup, that's what the nylon pin its for, it was there for a reason to start with.

Yeah mine was really corroded to almost nothing and did not work so I just removed it, it really is only a issue in really large waves and even then I crank it up a little more to put more tension on the cable.
