Every detail aboard the Boston Boatworks 44 Offshore Express Cruiser is carefully considered before an informed decision is made. For the propulsion system of the BB44, we’ve opted for Volvo DPI Aquamatic Drives.
Fuel efficiency is a primary focus. Diesel offers greater energy output per pound compared to gasoline and promises the most efficient fuel consumption. Pairing this with an azimuth drive, such as an articulating pod, ensures the effective transfer of horsepower to the propeller. For example, an IPS drive boasts about 20% more efficiency than a traditional inboard shaft strut and rudder setup, while the DPI system enhances efficiency by approximately 5% beyond that.
Beyond efficiency, these engines deliver enhanced power, producing more torque at lower RPMs than their gasoline counterparts, crucial for maintaining forward momentum when navigating through waves. The Aquamatic Drives ample low-end torque results in superior ocean-penetrating capabilities.
Moreover, the Aquamatic Drives offer versatility and user-friendly features, ideal for cruising. Stern drives are trimmable, allowing for easy tilting in shallow waters, convenient propeller maintenance from the swim platform, and vertical mounting, which minimizes roll when maneuvering with joystick controls. This enhances onboard comfort significantly.
In selecting the engine for a Boston Boatworks vessel, meticulous deliberation is evident. We believe this attention to detail resonates with our discerning customers, reflecting our commitment to Building Excellence in every aspect of our craftsmanship.
