: Would you clue me in on the Joe Greenley seat, I need to build a better seat
: for my COHO, one that doesn't make our legs ache or go numb......Wayne G.

Here is a link to Joe's seat page, if you order one from him it will be perfect, if you make it yourself you will have it sooner and you can customize it as you complete it. Just use a station form closest to the middle of the cockpit or make a form from a piece of cardboard. Use a piece of closed cell foam about 2x2x3ft 4in thick. Make seat about 16 in front to back, leave front of seat about 2 in off hull and carve cheek recesses down to about 1/2 inch of hull. Center an 8 in wide cheek plate on each side of the seat to fit your hips outside and the hull inside. The backband support should be 4 in wide, deep enough to reach back to aft bulkhead and 3/8 to 1/2 in higher than top to bottom dimension to allow for compression(under the cockpit coaming). Hip (cheek) plates should also be 3/8 in higher to allow for compression (under the cockpit coaming) as this compression is what holds the seat in place. The top of the backband support should be as high as the top of the coaming. The backband is made from either strips to match your boat or plywood or laminated plys glued up into an arc to match the back of the cockpit coaming. This is padded with 1 in thick closed cell foam. Slope backband 1 in back at top of 5 in wide band. Piece of cake, I've got two of 'em.
Glue up with contact cement, paint it on until it stops soaking it up and stays shiny when dry.
