:Is the length and beam the same as the S&G Guillemot?
:I don't think you need to tweak the dimensions much to have the boat qualify as 'original'.....

Hi John:
The length for the Coroplan kayak has been scaled down to 14'-9" from 17' with all the other dimensions seemingly left as is.

and Allan, Malcolm:
For sideview comparision purposes, I expanded the Coroplan image up to approx the Guillemot S&G image size and then scaled down the depth to see if they match. Aside from the ckpt also expanding they are essentially identical.

The frontview Guillemot image perimeter is exactly the same as the Coroplan section perimeter with no differential scaling - ie they overlay and match.
