Jeff is correct. There's lot of room to anchor
in Marsh Harbour. There is enough water
for almost any boat and the holding is excellent. In fact, the holding is so good that it is not uncommon for cruisers to anchor
their boats in the harbour and fly home for a visit.
That being said, as a long-term place to anchor your boat, I wouldn't recommend it. As more than one hurricane
and "norther" has proven, MH is just too open to the north. This allows wind
and surge do considerable damage. Any strong north wind
creates problems in the harbour.
For long-term storage
, you have two choices; mooring or dry storage
