You obviously haven't been stuck on a race course in the middle of a august afternoon on a North Carolina Lake.

In full gear.

While a canteen or other gear is nice, I've already lost three overboard. I've clipped them into the tramp lacing and everything but it gets hairy when its time to drink up.

Outlawing wetjackets and the like is fine, they don't serve an alternate purpose like a camelpack does.

If people are concerned that I'm going to outweigh them on the rail, then I'll go ahead and drink the equivalent of a load of bricks before the races and hold it.

Plus, my diabetic condition makes me more thirsty than your average competitor. I drained a 200oz bladder in under 2 hours.
