Overview

The Grand Mariner introduces an innovative integration with Mercury's single engine joystick system, enabling enhanced maneuverability for single-engine boats. This advancement allows the vessel to perform 360-degree rotations and precise parallel docking, significantly improving handling and control in tight spaces.

Exterior Design and Features

The boat features a thoughtfully designed exterior with adjustable seating that can be set at various levels or laid flat for comfort. A conveniently positioned cooler is accessible both from the deck and the water, allowing swimmers to easily retrieve refreshments. The Grand Mariner is equipped with a cladded power tower that includes interior lighting, enhancing both functionality and aesthetics during evening use. Upgraded wood trim accents provide a refined finish, complemented by premium JL Audio sound systems integrated into the design.

Cockpit and Bridge Technology

The cockpit center is elevated and incorporates sophisticated integrated lighting within the dash for improved visibility and ambiance. Navigation and control options include dual Simrad displays or customizable gauge configurations, catering to different user preferences. The helm features a joystick control dedicated to precise docking maneuvers, supported by premium wood-trimmed steering components. Lighting controls are managed through an advanced LED system with multiple modes, including SOS signaling for emergencies, automatic docking light activation, and a 'dock party' mode that illuminates tower lights for social gatherings.
