This is how it looks when made with stacked BS1088 plywood

: Here is my standard cockpit. I am 6"-2" with a lot of
: legs and like 4" clear behind my back to the coaming so my
: cockpit is 33" long (and 16" wide).

: You also see a woodworkers' trick for drawing curves (an equal
: number spaces on both sides with the spaces being equal length
: per side, on the two intersecting straignt lines tangent to the
: start and end of the curve; connect points between the spaces
: with straight lines).
