David,
Do you know what the big difference is be RV and a Boat???
Water can leak out of an RV......
Anchoring out becomes dry camping.
Gunkholing is call Boondocking
A slip is called a space and is still expensive.
Your holding tank is now a Black and/or Gray tank.
Pump out is now a dump, find them were you can.
Potable water is still a serious issue.
Shore power comes in 23,30 & 50 and the plugs are not twist lock.
If you were sailors, fuel will now be a lot more, but if you just sold a power boat, the fuel will be less.
Keep paper maps for the same reason you used to keep real charts.
You should still maintain written maintenance and voyage logs.
