We have chartered a power cat from The Moorings many times & it's always been a great experience. Jan 7, 2017 will be our 12th time. $6,000 including air & all boat expenses for the 51' cat per couple sounds right on. You will love the BVI Islands.
I had the same problem with our 380. Replacing the lower & upper track rollers resolved the problem. The 2 upper rollers are slightly different in height which alines the lock with the stricken plate. The job is at least a case of beer project. Good luck.
Your Shower Sump pump is under the floor hatch just in front of the Salon steps. !' square box with 4 screws on each corner. Take top off and clean. The pump may be shot. If so you will have to replace.
Good Luck
Has anyone installed a backup Camera? I would like to install a camera to be able to see full width of swim platform when backing into slip. I will either use a Raymarine E series GPS for display or install 7" delicated display.
I feel your pain. I've got the same problem on my 2000 380DA. Dometic no longer makes the exact 42 gal tank, but has a replacement. $835+tax & ship. We will also have to take riser & manifold off to access. Hope to make repairs in Oct.
