Freshwater vs Saltwater boat; ASA courses
Not only would I look at "fresh water boats" I would try to find a "northern boat". One that has not baked in the sun, sat in the warm salt water and. most importantly, one that has been hauled out every fall and had 8 months to "dry out".
After owning boats on the Atlantic Coast and Lake Champlain I can say that the differnce can be striking.
