The point I'm making here is: I'm using 8' plywood sheets rather than the 10' called for. After the framing had been faired, the contour looked just as good at 8' as at 10'.
The real thing is PRICE!!
Flounder Bay Boat Lumber: 3/8" AB Marine 4x8= $47.07, 4x10= $111.54
(We would also use 4x8 as longer sheets are getting
more difficult to come by. This means an extra butt joint but not a
problem. brw)
