Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Thanks Dave. I will need to check the port knee for integrity because I've got slight leakage down the chainplate. That's one reason my mast is down again this offseason - to pull and inspect and re-bed the chainplates. The other reason is to rebuild the mast step, and possibly replace halyards

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

IF cosmetic only, as it probably is, I would not cut out any sound laminate - its the long roving fibres that provide strength. (It's also a lot of work.) IF I were spending big bux on topsides paint I would fill and fair, and maybe bulk up first with 'glass/mat if the divots were deep enough.

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

I imagine a proper "repair" would be a major surgery, involving removing the hanging knee, cutting the dimpled section out of the topsides, rebuilding that section of the topsides to the original curvature and thickness and integrating the rebuilt section with the rest of the local topsides,

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

As Dave said, it may very well be cosmetic.  Just the same, would it make sense to reinforce this area of the hull if for nothing other than peace of mind?  Not sure if this would be over-kill or not.  Earlier in the thread mention was made of the boat builder/marina founder who used to repair

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

The ‘hanging knees’ on Penniless are made of plywood. I re-drilled one when I moved the chainplate because it was not symmetrical with the other side. Quite stout and well tabbed. I don’t seem to have any dimples, but have #593 and a tan hull. Gary From: CnC-List

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

As you say, probably nothing serious - you'd know by now. During that same boat search period, I nearly bought a CS36T, beautiful condition, crazy low price because of blistering. I backed out of the deal because I could not convince myself that the problem would not recur (again) - surveyor

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

So, what I've got is a "flat spot", not a "hard spot", in Don Casey's language. He says "Flat spots in the curved parts of a hull indicate trouble. They occasionally occur because the manufacturer removed the hull from the mold too soon, but more often they indicate weakness, damage, or a

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Graham's description is pretty much what I saw on one of two Corvettes I looked at closely. IIRC the corvette has one chainplate attached to a bulkhead, another to a "hanging knee". In one case (the boat where the hull distortion was pronounced) The hanging knee's glass tabbing was

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Thanks Mike, that's good info. If it was from over-tightening the shrouds, that must have been done by some PO. I just follow the owner's manual prescriptions - tightening the uppers until they're "hard to turn", and the lowers until they have an inch of play. I've never even put a strain gauge

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Hi Randy, Yes, that's it. I don't know about you, but for me as someone who is relatively new to sailing and did not grow up around boats his books are indispensable as I try to learn my way around boat maintenance. Regards ,  Graham Sent from Yahoo Mail on Android On Mon, Nov 28, 2016 at

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Thanks Dave. Regarding the book, the actual book I have is Don Casey's "Complete Illustrated Sailboat Maintenance Manual" - https://www.amazon.com/Caseys-Complete-Illustrated-Sailboat-Maintenance/dp/0071462848 - which is a compilation of six of his other books. Its first volume is "Inspecting

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

An over-tensioned rig and/or weak laminate is also one of the explanations that Don Casey gives for dimples near the chain plates in his book on inspecting old boats.  He also points out that "hard spots" may result from the hull flexing over an internal structure like a bulkhead.  This may be

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Randy At our previous club (Barrachois Harbour Yacht Club) one of our members and the founder of the marina was a former boat builder and was at the time buying and bringing boats to the marina for resale (smart way to fill a new marina). As a boat builder Dana would refurbish most of the

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Thanks Dennis. Agreed, in most cases, (see my other reply) however I have have seen several where dimples" would be an understatement. Agreed also that even in the case of the corvette, it was probably not a structural concern, though that boat did need one chain plate knee repaired. My

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

There are others on the list with factory/design experience who will be able to give a much more informed answer however. if it corresponds to some kind of internal structure I would hazard an amateur guess that its a "hard spot". the boat changes shape a bit over time but can't do so in that

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Thanks Dave. My boat has a non-hydraulic backstay adjuster, and has a "dimple" in the topsides in the area of the port chainplate. I did have it professionally surveyed, and the surveyor didn't mention it or didn't notice it. I also inspected the boat carefully myself after buying it, following

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

Dave, The list refers to this as "dimples". In particular there was a discussion years ago regarding early 32's. You can try to search the archives for it. Conventional wisdom is it is more cosmetic than structural. Bottom line is it is not uncommon in older C's. In my opinion, it has little

Re: Stus-List Buckled Topsides at the Chainplates (was Re: Brokers and surveyors)

First sighted when I was looking at a c corvette. This boat had older Dark blue awlgrip and had been upgraded (including hydraulic backstab adjuster) and was due again for a general refit When sighting down the top sides I detected some deep waviness (like 3/16 to 1/4" distortion) in the top

Dave I was intrigued by your mention below of "buckled topsides at the chainplates". What did that look like when you saw it? Cheers, Randy - Original Message - From: "Dave S via CnC-List" To: "C Stus List" Cc: "Dave S"
