Re: Chain plate or impact.

If the plate let loose a little it would put pressure out on the hull as the rig pulls it inward.

Re: Chain plate or impact.

That looks like impact from the INSIDE. A hit from outside that could cause that sort of crazing would be unlikely to have totally missed the teak rails. I would think there would also be a more distinct primary impact point - down to the glass - instead of just crazed gelcoat.

Could be caused by the expansion of corrosion inside those miserable glassed in chains.

Either way, happy grinding.

Re: Chain plate or impact.

Inside impact didn't happen.

There was a leak, previous owner silicone'd the crap out it.

The chain plates (3) are tied into a horizontal grid - which might explain the 't' shape.

The storm in June - Six Tornadoes Confirmed on June 13th

High water and a gust could have caused it, just don't know - if I took a hammer and hit it I'm real sure it look the same. My insurance co confirms if impact it's covered, if plates pulling it's not, unless the impact loosened the plates.
That's why I've got a thermal camera coming - no guessing and a certified surveyor to put in writing what caused what when.

Re: Chain plate or impact.

Not much of a way for it to have been impact from inside, but an impact to the rub rail and possibly the cap rail could have flexed the hull in around the chainplate. That would make it look like it was pushing out. When is your surveyor coming?

Re: Chain plate or impact.

Hopefully he's coming Wednesday. It's a hook up I happened on when Beth Leonard (yes, that Beth) gave me her card at the rigging talk during the SSCA GAM last weekend - she told me she might know someone.


I've been going crazy trying to find a method of non-destructive testing - apparently there is a guy in Trinadad that x-ray's chain plates for 800 bucks, but no one nearer - or at least they don't advertise or even admit it.

I can't just hole saw a core out because doing so might in fact destroy any evidence that it's not impact related.

Even my insurance agent is telling me to proceed cautiously towards proof. I've been gathering wind/rain and tide stuff to show impact is and was possible.

Re: Chain plate or impact.

If it were 'chainplate' stress, wouldn't it have cracked the inside liner also??????

There is no inside liner - the plates are embedded in the hull and then have cabinetry built over the area.
Only way to get to it is to disassemble the inside.
Here's a shot from the inside - you can see I had some long time ago water damage (more than 9 years the PO owned the boat).

Re: Chain plate or impact.

looks like chainplate stress to me. My Seasprite has it on both sides where the chainplates are embedded. One of the reasons they are coming out
