Thinkin' of a new project.
I've always liked the Cunningham Sea Kayaker S&G ... got the plans ages ago ... a couple of pages full of offsets. I wanna scale up the beam. So ... how do I do it?
One idea ... say I wanna add 2 inches to the max beam. This method assumes the angle of the side panel relative to the bottom panel is unchanged.
Bottom panel: Add 1 inch to the offset at the max width of the bottom panel ... take that number and use it to ratio the other bottom panel offsets.
Side panel: Widening the bottom panel lengthens the chine ... so determine the true length of the chine based on the stock offsets ... and the widened offsets ... and use those to scale up the length of the side panel.
Deck panels: Haven't thought much about it ... should be able to riddle out something similar.
I'm not averse to a little pattern making, trial and error, tweaking or whatever.
Anyone have any ideas?
