We had our boat in a marina - it cost us $750 a month. We now have a swing mooring up the coast that costs us $65 a month.
Our travel time there is little different to what it was getting to the marina. We have to dingy out to the boat so our planning has to be better because we can't duck back and forth.
But as another post said, sometimes the mooring is a destination in itself. We have had occasions where we went to the boat to sleep over Friday night and go sailing the next morning. The weather turned nasty so we just stayed on our mooring which is in a delightful bay with good protection and great local fishing.
This is where we are.
I have no problems with our new choice.
