Overview
About this vessel
The sought after 646 Walk Around is here after high demand. Engineered for serious offshore performance, this vessel is powered by the Yamaha F200XSB, paired with Helm Master Level 2 for precision control, with integrated autopilot and joystick functions available, and seamless low-speed manoeuvring. The propulsion system is completed with a Reliance SDS stainless-steel propeller and a dual-battery electrical architecture supported by a C-Teck twin charge port for reliable power management.
The helm is designed for clarity and command, featuring a recessed installation, tinted safety glass, and a Raymarine 12" Axiom Pro with 3D sonar technology for advanced underwater imaging. A cordless VHF upgrade, MS-RA210 Bluetooth stereo, and an auxiliary pillar-mounted switch panel enhance communication, entertainment, and system control.
Above, the raised hard top provides increased headroom and structural rigidity, complemented by an additional row of rod holders for expanded gear capacity. The bow is Minn Kota-ready with a reinforced mounting plate and rail modification, while the transom incorporates twin walk-through access points and a Katchya bracket for auxiliary equipment.
Fishing capability is elevated through a deluxe two-drawer bait board, a large clear-window live bait tank with aeration, a deck wash system, gaff racking, and six gunwale-mounted rod holders. A drum winch with integrated FF functionality and an anchor-ready plate streamline anchoring operations.
Interior comfort includes full cabin squabs with a fifth infill, bolstered seating with sliders, a port-side chilly-bin module, starboard two-drawer storage base, toilet mount, and an upholstered dash brow. Lighting is optimised with forward cabin illumination and dual-mode red and white wheelhouse lighting for night operations.
The vessel is finished with a full single-colour paint system and a comprehensive SeaDek package covering the bonnet, flooring, footrest, swim step, and rear gunnels for enhanced grip, comfort, and aesthetics. Walkaround drainage grates, recessed helm ergonomics, and a raised hard top contribute to a clean, functional layout.
Alloy Eastow trailer integration includes an Extreme trailer catch and tie-down buckles for secure transport. Safety gear is supplied to offshore standards, completing a package engineered for durability, capability, and confidence in demanding marine environments.
