Before I started building canoes I got seriously into canoeing--at least seriously enough to do it a lot and to read a number of books about it. Several of my books advocated putting your own through-holes in if your canoe didn't come with them, because if you have to pull or hold a canoe against a current (as in towing with another boat, or lining up or down part of a river) the lower the attachment of the line was, the less likely the canoe was to tip over. Through holes were also considered the strongest attachment point for tying down to a car since it goes right through the body of the canoe and can't be pulled off, like a deck.
A strong transport tie-down is kind of a trade-off, of course, because if you get too enthusiastic with tightening down the ends you can break the canoe over the car roof. But I put through holes in Patience and really liked the look of them as well as their strength, so they're my first choice for this kind of thing.
Congratulations on your progress fixing your Shark! Wow--it sounds big compared to a canoe; I'm trying to imagine a deck where the bottom and the top aren't the same piece of wood :-) Or are you glassing both sides of the same plywood?
