RE: [Paddlewise] Standardized tests for hatch leakage - was - Sea Kayaker Reviews

I think a better test would be to put about 50-100 pounds of weight in each
compartment including the cockpit and then invert the kayak, possibly even
rocking it back and forth for 20-30 minutes, this would avoid breaking the
boat but keep the hatches good and wet - I'd suspect most leakage would
happen when the kayak is sideways rather than completely inverted, since the
air pressure inside when it's inverted would tend to keep the water out - my
2 cents worth

Peter, this is an interesting suggestion. Have you thought of any good ways
to submerge the kayak? There's a lot of volume in a sea kayak. Perhaps a
couple of hippos from the local zoo could be trained to do it in a
standardized way. Or lots of lead... :)

Here's a question. Would the buoyant forces of submerged bulkheads produce
enough bending toque to break the kayak? Assuming of course that the kayak
is being submerged by a weight in the cockpit.
