Our son said you can buy a mooring there out right for 3000 but slips are 20yr waiting lists. That way we wouldn't be paying high rent. All suggestions please.
Well you certainly have a lot of research to do. Boat to look at, stories to read, all fun stuff.
Since this idea is motivated by family in a specific place you probably would want to find out more about the mooring specifics.
Where exactly would the mooring be. Protected flat water vs. bumpy rough mooring field can make all the difference.
What about dinghy docking? Do you have a safe place to leave a $2,000 dinghy and motor for when you are on land. How much, how far?
Water, fuel, food, repairs etc how much and how far?
It would be great if you visited and got to talk to someone already doing it.
Be aware the many Yacht clubs have moorings but do not allow live-boards.
Also if you find the perfect place you may find it easier to buy a boat at your destination. Getting a boat ready for a long trip with no experience is bigger job than just finding a boat and moving aboard.
