Our Thoughts

The 2024 Boston Whaler 405 Conquest represents a fully equipped offshore-capable express cruiser built for serious boaters who demand both performance and comfort. At 41.33 feet with a 13.5-foot beam, this hardtop-equipped center console delivers the seaworthiness Boston Whaler is known for, combined with a comprehensive cabin and galley setup that transforms extended cruising from endurance to genuine pleasure.

Power and Performance

Triple Mercury 600 outboards provide 1,800 total horsepower and establish this 405 Conquest as a capable performer across a wide range of conditions. With only 175 hours on the engines and manufacturer warranty coverage extending through December 2027, the propulsion package represents a significant asset. Joystick steering control modernizes helm operation, making precision maneuvering and station-keeping intuitive for both experienced operators and those new to larger center consoles. The self-bailing cockpit sole and 27-inch interior freeboard underscore the design's commitment to seaworthiness in variable sea states.

Navigation, Electronics, and Connectivity

The 2024 electronics suite reflects a comprehensive 2026 Garmin navigation ecosystem. Dual Garmin GPSMAP 9219 displays and a Garmin GPSMAP 9224 provide redundancy and operational flexibility across the helm station. The Garmin GMR 434 4-foot open array radar delivers reliable target acquisition and weather detection, while the Garmin GSD 28 sounder with CHIRP sonar and 3D capability supports both navigation and fishing. Custom acrylic panels flush-mount the GPS units into the helm architecture for a professional, integrated appearance. Maritime Starlink with Fire Stick connectivity ensures reliable communication and entertainment during extended offshore passages. Rockford Fosgate audio has been completely upgraded throughout, delivering high-fidelity sound in the cabin and cockpit environments.

Fishing Features

Rod holders are positioned strategically: three aft cockpit starboard, two port, five transom-mounted, and two under-gunnel starboard, accommodating multiple angling techniques and tackle configurations. The 19-gallon pressurized insulated livewell with dual white LED lighting and clear lid is located in the aft port corner, maintaining bait and catch quality during full fishing days. An ACR RCL-75 spotlight mounted on the hardtop supports night fishing and navigation. The dive door on the port side with removable stainless-steel ladder and dedicated storage provides safe water access for swimmers and divers. Two freshwater showers—one near the dive door and one at the transom—rinse tackle, gear, and crew efficiently.

Cabin and Accommodations

The cabin layout prioritizes comfort for extended cruising. The master stateroom features an island bed with 8-inch Premium Handcraft pillowtop innerspring mattress, electrically actuated hinged backrest, and trunk-style front storage with gas assist. Dual 120-volt receptacles, cedar-lined hanging locker with door-activated lighting, and a 24-inch flat-screen HDTV with Apple TV integration support relaxation and entertainment. The 8,000 BTU reverse-cycle air-conditioner with LCD control maintains climate regardless of season or location. Solid teak flooring with satin finish and pull-down pleated hull-side window shades create a refined aesthetic.

The mid-berth cabin includes a 6-inch Premium Handcraft pillowtop innerspring mattress with hinged storage access, LED reading lights,

2024 Boston Whaler 405 Conquest: Premium Offshore Sportfisher with Triple Mercury 600 Engines and Advanced Garmin Electronics
The 2024 Boston Whaler 405 Conquest represents a fully equipped offshore center console engineered for serious fishing and extended cruising. Located in North Bay Village, Florida, this 41-foot vessel combines Boston Whaler's proven hull construction with a comprehensive suite of modern navigation, entertainment, and comfort systems. Powered by triple Mercury 600 engines with 175 hours and factory warranty through December 2027, the 405 Conquest delivers the performance and reliability expected from a platform designed to operate in open water while maintaining the seaworthiness Boston Whaler has built over decades.
Hull Design and Construction
The 405 Conquest is built on Boston Whaler's signature deep-V hull with a 13.5-foot beam, engineered to handle offshore conditions while maintaining stability in a range of sea states. The hull incorporates a vinylester barrier coat over the entire hull and hull sides, providing long-term protection against osmotic blistering and environmental degradation. All hardware and rails are fabricated from 316-L stainless steel, a marine-grade alloy that resists corrosion in saltwater environments. The self-bailing cockpit sole ensures that any water that comes aboard drains automatically, a critical safety feature for fishing boats operating in variable conditions. The vessel features 27 inches of interior freeboard, providing dry-boat characteristics and reducing the likelihood of water ingress during rough seas. An acrylic transom door with stainless steel latch provides safe access to the water and dive platform, while a molded fiberglass dive door on the port side with removable stainless-steel dive ladder accommodates swimmers and divers. The boarding ladder at the transom and dedicated dive-door storage in the stern seat reflect thoughtful deck planning for both safety and convenience.
Deck and Cockpit Layout
The 405 Conquest's cockpit is configured for fishing, entertaining, and extended cruising. The aft cockpit features a foldout bench seat to starboard, a cockpit table, and a refrigerator for storing beverages and bait. Coaming bolsters provide comfortable seating along the gunnel, while strategically placed stainless steel drink holders (14 total across the vessel) accommodate guests throughout the boat. Rod storage is comprehensive: three gunnel-mounted rod holders aft on the starboard side, two on the port side, five transom-mounted holders, and two under-gunnel holders on the starboard side. A 19-gallon pressurized insulated livewell positioned in the aft port corner features a clear lid, blue interior, and dual white LED lights, allowing anglers to maintain bait and catch quality during extended offshore trips. Deck hardware includes 10-inch stainless steel cleats at the stern cockpit and bow, spring line cleats, and crosstie cleats at the transom. An anchor windlass with 400 feet of rode and chain, operated by handheld remote control, deploys a polished stainless-steel 44-pound anchor over a bow roller davit. A heavy-duty polished stainless-steel bow eye and high bow rails provide secure attachment points and safe passage to the foredeck. Welded stainless-steel hand rails run from the companionway to the helm deck and into the cabin, with additional rails at the boarding ladders and prep station. Two freshwater showers—one near the dive door and one near the transom door—allow crew and guests to rinse off saltwater. An ACR RCL-75 spotlight mounted on the hardtop supports night operation and docking in low-light conditions.
Helm and Navigation Electronics
The helm station is equipped with an extensive suite of 2026 Garmin navigation electronics, newly installed and integrated for seamless operation. The system includes a Garmin 9224 GPS chartplotter, dual Garmin 9219 GPS chartplotters, a Garmin GMR 434 four-foot open array radar, and a Garmin GSD 28 sounder module. Custom acrylic panels flush-mount the GPS units, providing a clean, integrated appearance while protecting sensitive electronics. CHIRP sonar with 3D capability enables detailed bottom and fish-finding information. Maritime Starlink with FireStick provides satellite internet connectivity and streaming capability, supporting both navigation and entertainment needs during offshore passages. Joystick control steering simplifies maneuvering in tight quarters and when docking, a feature that significantly improves handling precision on a vessel of this size. The helm console houses overhead cabinets with AC and DC vessel system controls, allowing centralized monitoring of power systems, generator operation, and onboard utilities. A 120-V receptacle at the helm supports charging portable devices and powering auxiliary equipment.
Entertainment and Audio Systems
A completely upgraded Rockford Fosgate audio package delivers high-fidelity sound throughout the vessel. The system supports both helm-deck entertainment and cabin listening, with speakers positioned to provide even coverage in all major areas. Integration with modern streaming sources ensures access to music and entertainment content while cruising. The master stateroom includes a 24-inch flat-screen HDTV with Apple TV integration, allowing streaming of movies, shows, and content during extended stays at anchor or dock. A new Ionic Nightwave digital camera system supports security monitoring and documentation of cruising experiences.
Power and Generator
Three Mercury 600 outboard engines provide the propulsion power, with 175 hours on the engines and factory warranty coverage through December 2027. This triple-engine configuration delivers the horsepower necessary for efficient cruising and responsive acceleration while maintaining redundancy—if one engine requires service, the vessel remains operable on two engines. A 1-kilowatt diesel generator with 120-V output powers the air conditioning systems, galley appliances, entertainment electronics, and other onboard 120-V loads when the vessel is at anchor or moored. The generator allows extended stays without relying on shore power, supporting comfortable cruising and entertaining regardless of dock availability.
Stabilization and Comfort Systems
A Seakeeper 6 gyroscopic stabilizer significantly reduces hull roll during cruising and anchoring. Gyroscopic stabilization works independently of speed, meaning the boat maintains stability whether underway or at rest—a feature that improves comfort for guests and reduces fatigue during extended cruising. Air conditioning is provided by a 16,000-BTU unit in the main cabin with distribution to the mid-berth, and an 8,000-BTU reverse-cycle unit in the master stateroom with LCD control. Both systems maintain comfortable interior temperatures in warm climates and support year-round cruising in Florida waters.
Cabin and Interior Accommodations
The 405 Conquest provides sleeping accommodations for up to four people: a master stateroom with island bed and a mid-berth cabin. The master stateroom features an 8-inch-thick Premium Handcraft pillowtop innerspring mattress with electrically actuated hinged backrest, allowing customizable positioning for sleeping or relaxation. Gas-assist hatch access to trunk-style front storage keeps the cabin organized and clutter-free. The mid-berth cabin includes a 6-inch-thick Premium Handcraft pillowtop innerspring mattress with hinged access to storage beneath. Both cabins have solid teak flooring with satin finish, providing warmth and durability while maintaining the aesthetic expected in a premium cruising vessel. Lighting throughout the cabin spaces uses LED technology with RGB diffused courtesy lighting and dimmer control, allowing occupants to adjust ambiance and brightness to suit the time of day and activity. Reading lights in both cabins support nighttime comfort. Opening ports and hatches provide natural ventilation and light during pleasant weather. The master stateroom includes a sliding pocket door separating it from the salon, providing privacy when needed. Hanging lockers with cedar lining and door-activated lights in both cabins prevent odors and provide secure storage for clothing and personal items. The master stateroom also includes overhead storage cabinets on both port and starboard sides with flip-up doors.
Galley and Provisions
The galley features a single cooktop burner, a stainless-steel 12-V/120-V refrigerator/freezer drawer with 3.0 cubic feet of capacity, and a microwave in the overhead cabinet. A solid-surface countertop with undermount sink and matching sink filler with integral cutting board provides workspace for meal preparation. Cabinet storage includes teak wood cabinets with satin finish and maple lining, overhead storage for dishes and galley supplies, and a pullout waste receptacle. LED RGB courtesy lighting under the overhead cabinet and countertop with dimmer control illuminates the work area, while an overhead LED white light provides general illumination. A wine glass holder mounted under the cabinet with integrated lighting
