: Hello,

: I've asked Tom Yost what the max. displacement for his sea tour 13
: is and got answered 275 pounds at 4 3/4 inch.

: No call me ingratefull, sceptical or even plain rude, but this
: seems incorrent.

: I've checked a couple of other designs, Nick's great auk 14, Ted
: moores Venture 14 and CLC's shearwater 14. All being a foot
: longer and both the auk and the shearwater have wider beams but
: they both don't even come close to 275 pounds.

: I even did a quick test in kayakfoundry and it's hard to get the
: displacement below 225 at 4 3/4 inch.

: Is there a quick way to calculate max. displacement for an existing
: design ?

Tom does it on the computer program the boat was designed on, I suspect the number he gave is correct.
