I want to repair a couple of cracks/gouges in the hull of my 13 foot '67 whaler. The cracks are through the laminate. The boat has not be used since last July and has been sitting in the drivway covered since that time. Should the hull be dry enough to make this repair and how can I tell?

If water isn't dripping and it doesn't feel wet to the touch, it's dry enough. Chips and cracks in the skin are not serious unless they expose the foam to moisture.

I read a good tip in some Interlux literature:
Tape a 1'x1' square of saran wrap, sealed around edges, to the hull. If you have condensation on inside of saran wrap after a couple hours, hull has trapped moisture inside. This might not matter for some operations, but they don't recommend epoxy barrier coat or extensive epoxy repair if you get moisture in this test. Good luck.

This sounds fishy to me. What about the moisture in the air? Might work if you vacuumed it out.

The plastic/saran 'patch'is the approved aerospace technique for determining if moisture is present. I have used it a lot. I think the manual says 24 hours, but you can apply the 'patch' then apply just a little heat, any moisture will condense on the saran.
