I have a hole punched into my outer hull in the keel trunk area from a fallen keel. The marina hauled the boat when they noticed that the bow was nearing the water line... I haven't dropped the keel out, but can see the damage.

I had planned to motor the boat 35 miles upriver to its winter storage home and am wondering if I can do a temporary fix.

Questions:

1. How much air space is there between the inner and outer hulls in the keel trunk area?

2. Does it sound reasonable to drill thru the inner hull and fill this air space w/ closed cell spray foam in the area of the hole as a quick, temporary fix for a 6-hour trip?

3. Anyone have any experience w/ impact damage to the keel trunk? I've scanned the posts and found a lot of broken cables and fallen keels but no one w/ damage to the trunk.

Thanks for any help, suggestions, empathy, sympathy.

Bruce, there is about 1-1/4 inch between the cabin sole and the hull, and about the same between the liner and keel trunk. I can send you a picture of that area. Need your email address.

Pictures would be great and will probably save me from cutting a hole from the inside to look around. Email: [email protected] An inch should be enough room for the foam to disperse. At any rate, it can't hurt to experiment and could help a lot. It's regrettable that they didn't fill that dead space w/ foam during construction, it would have strengthened the trunk area and reduced leaks after damage, but I guess at that time no one anticipated fallen keels and the resulting damage.

Bruce, I would rethink using spray foam as a temporary fix. Although it may get you "back home" that stuff is a bear to remove and will make your permanent fix a very unpleasant task.

Bruce,
I checked The MainBrace for a C22 fleet near you. It appears that there are several in NY. Get in touch with the Fleet Commodore for Region 1, [email protected]
His name, according to theMainBrace is Tom Newmann. Maybe he can direct you to a fleet near you where someone has a trailer to rent/loan so you can trail the boat home to be repaired.

Frankly, I would not run the risk of doing what you propose, and the repair may be much easier to do in your own back yard or with some of the fleet's help.

i would borrow a trailer. the hull flexes quite a lot and even a crack (much less a hole) can let a lot of water in quickly. if the boat is already out of the water, there are fiberglass kits you can buy that will fix the hole in a day. probably not pretty, but will do the trick. i was holed in a regatta, beached the boat, put gray tape over the hole and then motored it a mile to the dock. hauled out, my husband got one of the small fiberglass kits with cloth and kitty hair and did the patch with the boat on the trailer. five years later the patch is still holding. good luck
