About Boston Whaler

Premium production

American builder of foam-filled, 'unsinkable' outboard boats from Edgewater, Florida, part of Brunswick Corporation — twenty-one models from 6.5 m entered here, from the 210 Montauk to the 13-metre 420 Outrage, in the Montauk, Dauntless, Vantage, Conquest, Realm and Outrage series.

Boston Whaler says that since its founding more than sixty years ago it has set out to build the safest, easiest-to-own and most exciting boats on the water. Its founder, Richard Fisher, was so confident in his fail-safe boat that he tested it publicly, and LIFE magazine documented the whole thing; the company still says you can cut a Whaler in two and drive away in the half with the engine. That promise rests on its proprietary foam-filled Unibond hull construction, which gives the flotation and strength behind the 'Unsinkable Legend', and government agencies and military forces around the world rely on the boats. Whalers are built at the factory in Edgewater, Florida, where the company's designers, engineers and naval architects hold a long list of patents; improved facilities and technology have let it build more and larger boats, up to the flagship 420 Outrage. Boston Whaler is part of the Brunswick family.
