gkny 26 Posted November 5, 2021 Share Posted November 5, 2021 I had a cast aluminum chock that was integrated with the toe-rail that broke. It was a closed D shaped loop. I have looked for another but not found a matching one. I am thinking about using a square stainless u-bolt for the chock. I would like the line to be protected whether it is running forward of the cleat or aft of the cleat and the skene or angled chocks seem to work only in one direction. If I use a large diameter u-bolt (say 3/8") is that a large enough diameter to protect the line? Quote Link to post Share on other sites

Zonker 5,218 Posted November 5, 2021 Share Posted November 5, 2021 You want roughly the radius = line diameter. So a 3/8" diameter rod = 3/16" radius. i.e. a bit too much point loading unless you are tying up a dinghy with 1/4" rope. I would try to get a closed chock. It's entirely possible your existing closed chock had a fairly tight radius as well. Have a look. Just measure the thickness and see if it will be close to your 3/8" U bolt.

Rain Man 1,961 Posted November 6, 2021 Share Posted November 6, 2021 How about a picture of the good one on the other side of the boat. Maybe somebody on here has one. Quote Link to post Share on other sites
Gouvernail 3,933 Posted November 7, 2021 Share Posted November 7, 2021 Maybe I skimmed too fast but.. what kind of biat snd what year was it built… and the photo of the other side gets you hundreds of additional assistant search eyes. It is all about “fixit thread cred” You can bet your sweet bippy every one of us would like to be the first one to tell you where to get one. 1 Quote Link to post Share on other sites
El Borracho 2,609 Posted November 7, 2021 Share Posted November 7, 2021 FWIW - My dock lines run thru a square u-bolt at the bow. About 1/2”. Makes a 90° turn. Like wise ones @slug zitski & @Zonker said it is not recommended. The 5/8” line wears quicker that it should. $$$. Works for me though. I’m not supposed to be tied to a dock…COVID.

gkny 26 Posted November 7, 2021 Author Share Posted November 7, 2021 The boat is an X-372 from the late 80's. I have attached a picture of the port side. The starboard side broke when the boat took a big roll from a large boat wake. Any suggestions welcome. thanks! Quote Link to post Share on other sites

SloopJonB 12,534 Posted November 7, 2021 Share Posted November 7, 2021 Did you try contacting X-Yachts? If that's no go then Sluggo is right - find an alternate the right size and get two so they match side to side. Quote Link to post Share on other sites

SloopJonB 12,534 Posted November 7, 2021 Share Posted November 7, 2021 Exactly. Of course I rebel at the thought of different style screw heads under grain oriented teak plugs. Quote Link to post Share on other sites

Zonker 5,218 Posted November 8, 2021 Share Posted November 8, 2021 I have literally put up a small bracket with 3 different screw head styles. (Robertson / oval head and flat head Phillips). Have not managed all 4 quite yet. It's wrong but sometimes I've been a long way from a marine store. I'm like a Cuban car mechanic. "Oh look. Here's a bolt. It will fit... Moving on" Quote Link to post Share on other sites
