I know this question is more rhetorical than anything else (though I was
wondering where Andy was going with his post for second there...
, but it seems like fitting into your kayak the same way twice has more to do with seasons than anything else?
Layer me up for winter boating, and I'm gonna fit alot differently than I did back in September. But shed all those layers down to neoprene shorts for an indoor pool session a week later, and my hip pads don't touch my body at all. Also, if you're anything like me, ya' might put on a couple of lbs over the winter, but shed those pretty quickly once the sun comes out and the world starts heating up again? I've just accepted a few lbs of "winter weight" are going to happen each year at this point: it's when they don't drop off quickly or easy again that I'll start worrying!
For the sake of argument, though, I'm blaming boat fit on multiple layers of polypro, neoprene, and drypants on my hips, rather than accepting responsibility for anything else!
