Tony took this cool promo photo for me on our little waterfront:

My summer here started with work around camp, cleaning up and reorganizing our storage rooms and fixing boats. We had three kayaks with gaping holes in them from last summer. We have a trailer that doesn't have fenders over the tires and the kayaks sat on the tires during a 2 hour trip, resulting in massive holes in the sides. We needed those boats for this summer, so I fixed them with an old kayak, a blow torch and metal spoon. I figured since I was at it, I might as well make an instructable (a tutorial) on fixing one. In hindsight, I think a heat gun may have worked well, perhaps better than a blowtorch. Here's my instructable:
