Response to Roger
I'll respond now to keep this current but I do have a picture that I can post later if you needed. I don't have it with this computer. Yes there is sitting room, in the back half (wider) part of the cabin. That equates to about a third of the v-bunk. Aft of the V-bunk,yet still under the cabin roof, are three storage compartments, from port to startboard looking forward: one to port, walkway, then two to starboard. The first to starboard was orginally the compartment for a flush through head. The smaller compartment outboard to starboard is where our deep cycle battery is kept. It's weight is offset to the port by the outboard motor (inhull mount on the old boats).The compartments in the cockpit seat are in the forward portion, one per side. The starboard one is lined and has a plug to be used as a cooler but is not well insulated, the port is just open to the hull. They are about (estimated by memory) 20" long by 12" wide and about a foot deep inboard down to about 8" outboard. The combined inside and outside storage would likely not meet the 2+2 quarter berths but all of these locations can be accessed without moving other things. You do lose a security of a lockable hatch as the aft full aft wall of the cabin is canvas (sunbrella for us) but also nicely covered up with screening for great ventilation in hot sleeping weather. However you do gain a forward hatch that can also be screened and is nice to have if you need to poke through to the fore deck in bad weather. Finally, I'm not sure but I think you sit a little deeper in our cockpit since the seats didn't need to be high enough to have legs stretched out underneath but I can't be sure but I know it feels like more between you na the water.
