Bulkhead access ports
RumPirate, I noticed that the 3rd and 5th bulkheads (from the bow) did not show cut outs for access to the spaces between the adjacent bulkheads (2nd and 4th, respectively). These will be hard to cut in after the fact and you will need acess to these spaces if you cut in limber holes along the stringers. Are you planning on providing access through the seat tops? That could work!!
