How big is this boat and how much storage space does it have on it? I’m in no way a boat person, but for longer times out at sea would it be possible to tow a small (12-foot) inflatable raft or row boat behind it full of supplies? You may be able to pick up a inflatable boat rather inexpensively and stow it away or on shore close by and being a blow up raft it would be resistant to sinking.
