Bertram 510 Convertible: Italian Style Meets Legendary Offshore Muscle
1. General Information
Launched in 2000 and built until 2008, the Bertram 510 Convertible was one of the first models to blend the brand's legendary offshore capability with the sleek Italian styling introduced after Bertram joined the Ferretti Group. At 16.70 metres overall, this powerful sportfisher pairs a proven deep-V hull with elliptical windows, sweeping lines and a luxurious three-cabin interior.
The ideal owner is a serious tournament angler or long-range offshore cruiser who wants speed, seaworthiness and real comfort for family and crew. A 3,940-litre fuel capacity and a fast 28–30 knot cruise put distant canyons and islands within easy reach, while a 700-litre water supply supports extended trips.
2. Construction and Design
The 510 keeps Bertram's signature deep-V hull, which delivers a soft, predictable ride with a slow, gentle roll and excellent manners in head and following seas. A beam of 4.93 metres provides a stable fishing platform, while a 1.52-metre draft remains practical for most sportfishing ports. Styling reflects the Italian influence of the Ferretti era, a clear departure from the classic Bertram look.
Inside, rich cherry joinery sets an upscale tone. The salon offers an L-shaped lounge to port, an entertainment centre to starboard and overhead rod storage, with a full galley forward featuring Corian counters and Sub-Zero refrigeration. Three cabins include a master amidships, a VIP queen forward and a guest cabin with twin berths, served by two heads.
3. Key Features
Tournament-ready cockpit: A transom fishbox, in-deck storage, freezer and a tackle centre with sink and livewell give a big crew everything needed to fish hard.
Twin MAN diesels: Around 1,050 hp per side delivers a 28–30 knot cruise and a top speed in the 30s, reaching 30 knots in just over 20 seconds.
Sea-kindly deep-V hull: Bertram's proven running surface tracks well downwind and drifts steadily in big seas, ideal for long days on the fishing grounds.
Three-cabin interior: A master, a VIP queen and a twin-berth guest cabin with two heads accommodate family and crew in comfort.
Accessible engine room: Entry from the cockpit gives straightforward access to filters, fuel valves, generators and air-conditioning plant.
4. Summary
The Bertram 510 Convertible is aimed at tournament anglers, charter operators and offshore enthusiasts who want a fast, capable sportfisher with genuine liveaboard comfort. It suits owners who value Bertram's deep-V heritage but appreciate more contemporary styling, and it remains an appealing used-market choice for crews heading far offshore in search of big game.
