on my 12' gregor, i made a single deck from the middle seat to the bow seat. the deck over the open area, I hinged for access to the 6-gallon plastic gas tank and storage for life vests, ropes, misc.

The middle seat had been previously cut open and had an ice chest inserted for an informal fish hold. (for dinner, not for C&R)

I have a pedestal seat on the opening part of the deck (just in front of the middle seat) but I'm going to switch it to a leaning post type of seat.

i have a clamp-on swivel seat on the rear bench. 2 batteries behind the rear seat with a 2x4 framed removable cover.

i made a 3/4" plywood bow "pulpit" to mount the foot-op electric.

20hp merc clamp-on and off I gooooooooooooooooo.
