I have a Hardin 45. tanks are all 90 gallon, fiberglass
, and accessible under the raised salon deck
by inspection ports
in floor or outside/plumbing under companionway
ladder grate. I can sit/crawl down in this space.Another 100 gallons in the aft captains quarters could easily be accomadated around the drawers/rudder shaft, This seems to be the lighter storage
area of the boat, as long as you don't fill up the aft deck
like the previous owner of ours did. He had 2 full size deck boxes and a 12' dinghy/25hp on the aft deck! This boat does not have a cutaway.
