Some one redesign the interior of my captain cabin. It have full size bad and a lot of cabinets. I like the set up, but it is nightmare to maintenance. I still can not figure out the trough hull on portside at the very back of the boat. To get to see it, I have to take the big mattress out and partially disassemble the bed. The rest of it is cover by cabinets and floor. What is that trough hull for and where is going?.
