Wade's Boom Truck, Bridges Point Boatyard, Brooklin, Maine. (1967 Ford F-600)

Used for stepping masts, of course. Wade Dow built the famous Bridges Point 24's, which were designed by Joel White. The boats are now being built at the Bridges Point Boat Company over on Mount Desert Island. Mr Dow still maintains & stores a fleet of BP 24s at Brooklin. There are some great stories and essays about Joel White and his legacy as a boatbuilder and designer at OffCenter Harbor.com.  I think subscription to OCH is $29/year which is a deal, for a rich source of information and advice about boats, Maine, sailing, and all things nautical.
