Each year for the past few years, about this time, I wander online dealerships and dockside inventories of salty boats, realizing that I would need storage somewhere because my house isn't equpped to park anything over 20 feet. Plus, my other two boats are more or less filling any available space anyway. Each year I think maybe next year.
Storing a salty boat in a cozy, locked garage at the coast is a great idea, one that I will definitely look into. This option saves on fuel and wear and tear from the elements, and gives you a protected place to do maintenance and repairs when the weather is nasty.
