The 2026 Boston Whaler 405 Conquest is a 40-foot center console built on a fiberglass hull and powered by four Mercury engines delivering 1,600 horsepower. The boat combines open-water capability with a design focused on stability and handling across a range of conditions, from day cruising to offshore fishing and exploration.
The 405 Conquest centers on a flexible open layout typical of the center console format. A single head is incorporated into the design. The helm area features advanced navigation systems, and seating throughout the boat emphasizes comfort and functionality for extended time on the water.
Boston Whaler's construction standards are evident throughout the hull and deck, with attention paid to quality materials and finishing across all visible surfaces and operational systems.
