Are you looking for a twin-diesel flybridge cruiser that blends proven coastal capability with genuine family comfort, this well-presented Mariner 3800 deserves serious attention. Australian-built and highly regarded for its solid construction and generous 4.47m beam, the Mariner 3800 offers the space and feel of a much larger vessel with an expansive cockpit, and a flybridge designed for long days on the water.

Powered by twin Volvo TAMD61A, 306hp diesel engines, she cruises comfortably at 17 – 19 knots and can reach 22 knots plus when needed. With her practical layout, predictable handling, and versatile design, she would also make an ideal first launch for buyers wanting to step confidently into boating with a vessel equally suited to cruising and sportfishing.

The Mariner 3800 is an iconic Australian flybridge cruiser with timeless lines and the practical pedigree to match. She carries the classic stance of a serious sports fisher yet offers the warmth and volume of a capable coastal cruiser. Crystal’s wide-body and three-quarter keel deliver confident tracking underway and excellent stability at rest. Whether you are trolling the coastline, anchored in a quiet bay, or enjoying a weekend away with family and friends. Her large flybridge offers comfortable seating for up to eight, complete with an updated GRP hardtop and clears, while the elevated helm gives the skipper superb visibility in all directions. Below, the open-plan saloon is light, spacious, and welcoming, with an L-shaped lounge, generous dining table, and full lower helm station. The step-down U-shaped galley is well positioned to keep the crew connected to the conversation while still enjoying sweeping views across the water.

Accommodation is comfortable, practical, and ready for extended stays aboard. The forward master cabin features a walk-around island berth, storage shelves, cupboards, and additional stowage below, while the starboard guest cabin is fitted with two generous bunks, a hanging locker, and a large drawer. Together with additional saloon sleeping space, the layout provides excellent flexibility for family cruising, overnight fishing trips, or weekends away with guests.

At anchor or in the marina, Crystal’s 230v 6.5kVA Onan  genset, powers the hot water, microwave, hob, refrigeration, and battery charging needed for comfortable time away. Whether your plan is a relaxed coastal cruise, chasing fish offshore, or covering distance quickly and comfortably, this is a vessel that delivers with confidence.

For buyers stepping into their first launch, or friends looking to share ownership of a capable and well-maintained vessel, Crystal represents an excellent entry level into the world of boating. She offers the reassuring blend of great seakeeping characteristics, serious sportfishing potential, and comfortable accommodation that makes time on the water both enjoyable and practical.

Please note, this vessel is not located at our Westhaven Sales Arena, so call to arrange an appointment to view her on her Auckland marina berth.
