Hello

I'm new - live in South Puget Sound - Have been reading site ever since I discovered it and look forward to meeting some of the folks here.

I appreciate your contributions - the information was very helpful to me in the early decision making stages and continues to be a nightly enjoyment - what a great group.

A little background then a couple of questions. Hope I posted this in the right area.

I recently purchased a 2000 CD22 - third owner with Honda 40's - during the marine survey - it was noted that there was a very fine crack in the interior hull under the left upper corner of the sink where the lower and upper hulls join about 10" long. I do believe the 2nd owner never saw it - very hard to pick up - but one could slide very fine knife blade inside. - Moisture detector did not notice problems in the related areas. Local Fiberglass tech said it could or could not be a big problem - suggested I mark the ends with pen to see if it was extending [ has not the last month] about 20 hrs or more of travel. No damage or repair to the outside of the hull or anywhere else for that matter.

I realize that we don't want condensation in side - and will post photos once I figure out how to do that on this site.

Its out of warranty and third owner but I wonder if I should contact someone at the factory - if so who. Or does anyone know a good fiberglass repair.

I realized this was a risk in the purchase but decided it was time to make this life change.

Thanks

Jim

Jstates – contact the factory. You will find them very helpful. Their contact info is HERE.

It is easy to post photos once you have an album. If one of the administrators is around and reads this, you will probably have one soon. If not, PM one of them TyBoo or Da Nag and request a photo album.

Welcome to the site and thank you for becoming an active member.
 
Jim,
If the crack doesn't appear to be getting worse, you may want to work a little 3M 5200 into it with your finger, wipe off the excess with abit of lacquer thinner and get on with life. :)

If it was that hard to notice it sounds like you got your moneys worth with the survey.
 
If you do go that route -- be sure and stop drill the crack to prevent it from lengthening (drill both ends with a 1/4 (min) drill bit) -- relieves the stress point. You can fill it with any fiberglass mix.
 
I wouldn't drill into the hull, very thin. I would say that when they put the top on they did not use enough epoxey on that one area. I would do as KATKT suggested and not worry about it. It should be a natural seam and not a crack in the fiberglass. C-Otter
 
Sounds to me like it's a "space" between the hull and the deck where the pulling things don't quite pull it together. Not a "hull crack" at all.

Stop-drilling cracks is a very old aviation procedure, where cracks are comon. If the crack is drilled and filled, you should have full strength (for all practical purposes) of the part again (you fill it with fiberglass or a derivitive and paint). The trick with fiberglass is to make sure you've found the end of the crack to relieve the stress. If you drill behind the end, you'll simply be drilling a useless hole. If it's a non-critical location and you don't care about the crack -- by all means, let it go.

Stop-drilling on F-111:

It sounds to me as if this is at the hull to deck joint--and is not really a defect in the hull. Look and see how it relates to the areas which are puttyed over with epoxy which covers the fasteners inside the boat.

I don't belive that this area is cored--the bottom is what is cored.

Epoxy will bond much better than polyester in a secondary bond. However the safest repair is to epoxy a strip of fiberglass over this "crack, after filling it with epoxy. This will entail sanding down the surface gel coating (which is applied after the boat is bonded together). Normally one would taper/step repairs--but if this is just the Hull to Deck joint, a single layer of cloth will not cause a hard place.

I agree, discuss the repair with the factory before taking action.
