2020 Boston Whaler 405 Conquest

The 405 Conquest delivers heady performance, serious fishability and versatility for easy cruising.

Boston Whaler continues to build upon its 60-year reputation as a pioneer in creating unsinkable hulls, even as it continues to refine its designs to send today’s boating anglers out in solid, comfortable style. It’s among the top two boat brands that respondents would consider purchasing for saltwater fishing, and among the top three our respondents currently own.

Boston Whaler has seven distinct lines, among them the Conquest family: a fishing-focused craft that also serves as virtual homes afloat, with dining space, cabin with enclosed head, galley and entertainment zone, and other features to delay the return to port delightfully—and catch plenty of fish while at sea!



Boston Whaler’s 405 Conquest delivers heady performance, serious fishability and versatility for easy cruising.

The cabin boasts master and guest sleeping quarters, teak cabinets and sole, ample rod storage, an enclosed head with separate shower, and galley.

At the helm, a single-piece windshield and half side glass or optional full side glass provides total visibility and protection.


For the angler, an optional deluxe prep center at the transom includes a corian topped bait-prep area with hot and cold water, fillet board, 40-gallon pressurized livewell, tackle drawers, leader holders and net bucket storage. Exchange the bait prep area for a summer kitchen and stick with a 19–gallon pressurized, insulated aft livewell.

Fifteen rod holders include ten on the gunwales and five shot guns. A pair of undergunwale rod holders at starboard and hard top holds six more.

Foldaway cockpit seating adds comfort while keeping the deck clear for a fight—a feature prized by 84 percent in our survey. Mascerated fish boxes are refrigerated and she can be rigged with Gemlux 22-foot graphite outriggers.


Boarding options include a transom door and port side dive door with stowable ladder.

Max available power is quad 400 hp Mercury Verado engines, with Joystick Piloting optional, as well as a Seakeeper gyrostabilizer, which one-third of prospective walkaround boat buyers said they’d consider.
