Each of these has obvious advantages and disadvantages and you have to decide what you want to do with the boat now and in the foreseeable future.
Heading back to Lake Ontario for this summer. Now in Bermuda and heading to Long Island Sound in the first week in May. Then on to the Hudson and the Erie Canal.
