Thanks Malcolm,
That's a great solution to one of the perennial problems of deck fittings. Just in time for my current project!

p.s. Do you guys know about TEDtalks.com ?? They're lectures by some very interesting people.
The ones I watched yesterday when it was too hot to work outside covered situations like this one. This surfboard solution is outside my kayak-teacher-photographer-writer world, but it's in Malcolm's. So you share, we learn, things get better. Of course surfboards aren't very dissimilar from kayaks, I'm sure there are many more divergent connections.

One TED speaker asked 'Who invented the mountain bike?' No company, no design team, nobody invented the MTB, everyone invented them. MTBs are now 65% of the US bicycle market, $18 billion. (Imagine kayaks growing that fast and huge, a little scary.)
These are the ones I watched yesterday.
