Boston Whaler 405 Conquest: BoatTEST Review
Overview
The Boston Whaler 405 Conquest represents the largest model in the Conquest lineup, designed with versatility in mind to accommodate families who enjoy both fishing and cruising. This model offers customizable features that cater to a dual-purpose lifestyle, blending comfort and functionality seamlessly.
Cockpit and Exterior Features
The cockpit of the 405 Conquest measures 11 feet 3 inches wide by 6 feet 6 inches fore and aft, offering a spacious and adaptable area. The standard layout includes a flip bench seat at the stern, while an optional summer kitchen replaces this with an electric grill, stainless steel rail, drawer-style refrigerator, sink, and multiple beverage holders. Storage is thoughtfully integrated, including dedicated spaces for a five-gallon bucket and cockpit tables, which Boston Whaler terms 'point-of-use storage.' For anglers, an optional aquarium live well can substitute the summer kitchen, with kitchen features relocated forward under the lounge. Additional fishing amenities include a 19-gallon live well in the aft port corner, rod holders, hawse pipes, racks for downrigger balls, and a first-in-class port side hull dive door with a heavy-duty stainless steel latch for hauling large fish or launching divers. The cockpit also features low-pressure glycol-filled cooling tubes for the 290-quart fish boxes, enhancing ice retention. Comfort and convenience are addressed with an optional 7-foot long sure shade, multiple rod holders on the hardtop, aft-facing lounge seats with beverage holders, a cooler with dual access, a pull-out shower, and wide passageways with secure rails leading to the foredeck. The foredeck itself boasts a 70-inch long by 58-inch wide sun pad with adjustable headrests, cup holders, grab rails, stereo speakers, and USB plugs.
Helm and Cockpit Galley
Access from the cockpit to the helm deck is facilitated by 9-inch tall steps with a 28-inch wide space between seats. The helm features a single-person seat that slides on a power base, with armrests and bolsters that fold up and a swivel function allowing the captain to engage socially when docked. The cockpit galley includes a Corian countertop, a single Kenyan burner, a sink with a fold-up faucet and removable cover, along with ample storage through drawers, cabinets, and a drawer-style refrigerator. The helm windshield is equipped with Boston Whaler's patented power vents and offers an optional full glass configuration. Additional features include overhead spreader lights, outrigger handles, speakers, courtesy lights, and a soft zipper pocket for storing the cockpit enclosure. An optional power skylight replaces standard hatches to enhance natural light.
Interior Living Spaces
The cabin provides six feet two inches of headroom and begins with a private bow stateroom, a highly requested feature in this size class. The sliding cabin hatch is uniquely designed with an articulating lower section to accommodate the hull's V-shape, a patented innovation by Boston Whaler. The bow berth, centered on the boat's axis, measures 80 inches long by 58 inches wide, with steps on either side. It includes adjustable head positioning for reclining to watch a 24-inch TV and stereo system located aft to port. Storage is abundant, with a cedar-lined hanging locker to starboard, a cedar-finished closet with shelves to port, and a large berth base that opens on gas struts for storing sizable items such as a life raft or luggage. A Dyson vacuum cleaner is standard and stored in the bow locker.
Heads and Additional Cabin Features
The private head compartment is accessible both from the master stateroom and the salon, featuring a separate shower area with a rainfall showerhead and a pull-up wand. The showerhead is designed to be recessed into the overhead in future models. The head also includes a vessel sink with Corian countertops, a skylight, and an opening port for ventilation. The salon area benefits from overhead skylights and hull-side windows that provide ample natural light. The dinette table folds to allow easy access and lowers to create additional sleeping space suitable for one adult or two children. Entertainment is supported by a stereo and a 32-inch TV, while controls for cooling, fish boxes, water maker, Sea Keeper, TV antenna gain, and air conditioning are discreetly housed behind overhead cabinet doors.
Galley and Aft Cabin
Located to port of the cabin steps, the galley is equipped with a single burner stove and a sink set in a Corian countertop, complemented by overhead storage and glass and beverage holders. Below the sink, an Isotherm refrigerator and a wastebasket are integrated. Above the galley, a cedar-lined locker offers additional storage with various shelves and compartments. The aft cabin features an 82 by 55 inch mattress that raises on a power assembly to reveal substantial storage beneath. Optional overhead racks can accommodate up to six fishing rods, enhancing the boat's utility for anglers.
