I would like to know if the kayaks hydrodynamic properties are changed if I would enlarge a Sea Rover to 18 Ft by scaling up all the dimensions by 18/17 (17 Ft being the original length). I'm about 200 Lbs, need a somewhat bigger boat. I've already build a Sea Cruiser folder and now looking for something quicker in wood, ballistic nylon skin and non folder. Hope you have some answers out there.

I think you might get more help on this from experienced skin on frame builders over at QajaqUSA

Responses to such inquiries seem to be plentiful and prompt.

It's certainly a possibility, but there is no need to strech / widen the Sea Rover as there are other designs available.

It would be easier to stretch a Sea Rider to 18ft by extending the stems only ( shallower slope) a few inches fore and aft while retaining the original cross section width and spacing.
If it's a roller you're after, the Sea Rider is actually better than the Sea Rover.

If you want a skinny Greenland, the 19' X 18" Sea Glider should fit well with your 200lbs.
