Offshore Boats
Center Console
These open freshwater and saltwater fishing boats are built to take rough offshore waters in pursuit of ocean fish like grouper, various billfish, mahi mahi and other migrating species of big game. A baitwell is necessary to keep live bait on board and fish lockers should be insulated to keep fish iced. An aluminum and canvas t-top provides shade and rod storage. Gunnel rod holders, outriggers and other gear are common fittings onboard a center console.

Walkaround
These may be the ultimate family fishers and are most popular in coastal waters, large bays and the Great Lakes where anglers pursue salmon or offshore ocean species. They are equipped with rod holders, livewells and steps to the forward deck to make it easy to follow a big fish around the boat. Walkarounds feature stowaway family seating, a cozy cuddy with plumbing for a toilet and sink that make them a winner for saltwater and freshwater fishing, cruising, swimming and tubing or skiing.
