In Response To: Re: Seat of the pants tests (Ross Leidy)

: I agree. And furthermore....

: I don't think there is a practical test. It seems to me that the only
: reliable test is to take your boat into the most wicked conditions that
: you ever expect to encounter and see if it survives. Even then, because of
: possible fatigue effects, you could not count on the same boat surviving a
: second trip through the exact same conditions (assuming you could
: duplicate the conditions).

: You can build and statically test all the panels you want, but all you get is
: imformation about relative strengths of test panels. You may choose to
: apply that information to the construction of a kayak, but when it's
: complete, you still won't know if it's a 'safe' kayak enough unless you
: take it out and destroy it in actual paddling conditions. It's not even
: enough to jump up and down on the deck, because all that tells you is
: whether or not it's safe to jump up and down on the deck. You may choose
: to interpolate using that bit of data and guess that it's a safe boat, but
: without destructive testing of an actual boat operating in actual
: conditions, how can you really be certain?

: But there again, there's the difficulty of reproducing the test conditions to
: get a fair comparison for subsequent boats.

As an instructor for the New Zealand Mountain Safety Council, I learn much more from reading accident reports than from scientific papers about hypothermia etc. Its what happens in the real world that counts in the end. Lets hear from people who have had failures, even minor ones, so we can all learn from them. Did your seams fail? does your hatch leak? how hard did you have to hit a rock before your boat broke? how many times did you drag it over an oyster bed before the cloth wore through?

As a lapsed engineer (BE [civil] specialising in fluid mechanics, 1978) I find all the engineering discussion interesting but largely irrelevant to the goal of building a beatiful boat which will meet basic functional needs, and getting out on the water to enjoy it.
