Second Dumb Question--Cape Dory Typhoon Chainplates

[peter guerrero]

I understand Cape Dory provided a reinforcement kit to correct a weakness in the chainplate fasteners/assembly. Has anyone installed this kit or reinforced their chainplates? If so, what did you do? See my earlier post about whether to unstep the mast to undertake this repair or whether a single shroud can be loosened with no ill effect. The boat is in a slip so it will be subject to some motion during this repair.

have not heard of such a kit for the chainplates. they did have a set of fiberglass knees that could be added inside the cabin to expand the load area for the side decks in the area of the chainplates. these were to help keep the cabin from depressing under the load of mast compression via shroud tension. i doubt you could find these, that is why ty owners install compression posts if they have this problem. search the archives for lots of info on this subject.

Peter-The Ty chainplate setup is very strong-it should not have to be reinforced. The deck may have to be. And regarding sloopjohn's post, as I believe the bolts do NOT go thru cored deck. I had a leak from the chainplate a few years back and decided to remove and rebed them. You need a real rubber arm, but I was able to remove the nuts with a socket wrench, extension and a long socket. I was however unable to budge the bolts. Instead of hammering or any other destructive method, I abandoned the plan and just put nylock nuts with washers back on smeared with lifecaulk. The leak was cured!

mike/peter,
the chainplate bolts do go thru the deck. when i redid the non-skid on my deck last year i removed the chainplates in the process so that they could be rebedded. i had to pry them out gentley but did not pry under the chainplate fitting for fear of ripping up the deck. i placed tape on the fitting to use as a padded base for the screwdriver i worked under the head of the bolts and then pried up. everything appeared dry and i had no leaks in this area so i simply rebedded the fittings when the deck job was completed. the bolts appeared in good shape, but being 25 yrs. old i put in new ones as cheap insurance.

According to the diagram in the CD Manual, the chainplate bolts go thru the hull-deck joint: there is a lip on the outer edge of the deck which sits on(and is bonded to) an inward turning flange on the hull. The balsa core of the deck is farther inboard. That's why I was not concerned with water migration into the core.

Its 66 degrees here on Long Island now-but our boats are all on the hard! A little more skiing till we can go sailing again!

72 in philly and very tempting to launch the Laser, but that water is still awful cold and the Laser is awful wet!!!

Did some Laser sailing this fall, and I had a blast! I think I may pick one up this season.
