Our Thoughts

The 2001 Bertram 510 Convertible represents a compelling entry point into the classic convertible market, combining the storied Bertram battlewagon hull design with a thoughtfully modernized interior and substantially refreshed mechanical systems. At 51.83 feet with a 16.17-foot beam and 5-foot draft, this vessel delivers the seaworthiness and fuel capacity—1,040 gallons—that serious offshore cruisers and fishermen expect, paired with cruising speeds of 28 knots and a top-end capability of 31.5 knots.

The twin 1050 HP MAN 2840LE403 engines with ZF BW155A.1 transmissions form the mechanical heart of this boat. Critically, both powerplants underwent complete 1000-hour service cycles in 2025, including full tear-downs, valve work, new injectors, thermostats, belts, water pump housing rebuilds, heat exchanger and aftercooler servicing, and gear service. The engines carry just 35 hours since that comprehensive maintenance, and the Kohler 15.5 kW generator—at 5,160 hours—rounds out the electrical generation picture. Fuel management is handled by dual Racor 1000 main filters and a Racor 500FG generator unit, with an Oberdorffer oil-changing system installed on the port engine for ongoing maintenance convenience. Supporting systems include six Power-Mate 8 D batteries, a Charles C-Charge 5000 charger, a ProMar ProNautic 24V/30 Amp charger, and a NewMar DC-DC converter.

The 2025 electronics suite is the standout feature for modern boating. The vessel carries a primary Garmin Chartplotter 8612XSV 12-inch display, two Garmin Chartplotter 8215 15-inch units, a Garmin GMR2536 XHD3 25kW radar with 96-nautical-mile range and six-foot open array antenna, an Icom M604 VHF radio, and a Garmin 740S GPS 7-inch screen. Navigation and boat control are further supported by a Simrad AP-22 autopilot, Danforth Constellation 4-inch compass, and Mathers electronic controls. Connectivity includes Starlink High Performance flat antenna and Starlink router for modern offshore communication. Audio entertainment is handled by a Fusion MS-504 amplifier paired with a Fusion MS-RA 70 stereo system. Additional electronics include a KVH Trac Phone dome, KVH Trac Vision system, an Icom M59 VHF in the salon, ACR remote spotlight, and Bennett trim tabs.

Deck hardware reflects a well-equipped cruising and fishing platform. A Simpson Lawrence windlass with 50 feet of 5/16-inch chain and 250 feet of 3/4-inch strand, paired with an Ideal windlass backup, secures ground tackle. A Wesmar bow thruster adds maneuverability in tight quarters. Outrigger configuration includes three Pipe Welders spreader outriggers. The hardtop is fiberglass with a 3/4 enclosure, and all windows were recently removed and rewedded.

2001 Bertram 510 Convertible: A Classically Built Convertible Yacht with Modern Systems and Serious Fishing Credentials
Overview
The 2001 Bertram 510 Convertible represents a enduring design philosophy in the world of offshore motor yachts. At 51.83 feet in length with a 16.17-foot beam, this convertible delivers the kind of sea-kindly hull and interior versatility that has made Bertram a respected name in the sportfish and cruising markets for decades. The vessel combines the proven seaworthiness of Bertram's battlewagon hull design with a thoughtfully appointed interior that accommodates families and fishing crews equally well. Powered by twin 1050-horsepower MAN engines, the 510 Convertible achieves a cruising speed of 28 knots and a maximum speed of 31.5 knots, making it capable of reaching offshore grounds efficiently while maintaining the fuel capacity and range expected of a vessel in this class. Located in Key West, Florida, this 2001 model has undergone substantial mechanical updates and a comprehensive electronics refresh in 2025, positioning it as a capable platform for both extended cruising and serious fishing pursuits.
Layout and Deck Design
The 510 Convertible's interior layout departs from typical convertible conventions by offering three full staterooms rather than the cramped upper-and-lower berth arrangements common to vessels of similar length. The master stateroom occupies the port side of the lower deck, featuring a centerline queen berth with a full-length cedar-lined hanging locker and substantial drawer storage built into the pedestal base. The en suite head includes a full-length Corian countertop with molded sink, mirrored medicine cabinets, fresh water Raritan Elegance toilet, and an enclosed glass shower stall with a Bomar hatch overhead. Forward of the master, the VIP stateroom mirrors the queen berth configuration with additional cedar-lined hanging storage to starboard and a mounted 43-inch Samsung Smart TV installed in 2025. This stateroom shares an en suite head with the guest cabin, appointed with a molded oval sink, Corian vanity, and bi-fold shower doors. The guest stateroom represents one of the 510's most distinctive design features: rather than stacking bunks, Bertram engineered a side-by-side single berth arrangement tucked ingeniously beneath the salon stairwell and dinette. Each bunk includes individual drawers, reading lights, and a shared cedar-lined hanging locker. A 15-inch Smart TV and night stand between the berths complete the space, making it genuinely comfortable for children or crew members rather than a cramped afterthought. Topside, the 510 Convertible presents a well-organized fishing and cruising deck. A fiberglass hard top with three-quarter enclosure provides weather protection for the helm and upper salon areas. A Simpson Lawrence windlass with 50 feet of 5/16-inch chain and 250 feet of 3/4-inch strand handles anchoring duties, while an Ideal Windlass provides redundancy. Marlin helm chairs flank the wheel, and all windows have been removed and re-bedded as part of recent maintenance. Molded-in spreader lights, Kahlenberg white trumpets, and a Glendinning Cablemaster complete the deck systems.
Helm and Electronics
The helm station integrates a comprehensive 2025 electronics suite centered on Garmin marine systems. A 12-inch Garmin Chartplotter 8612XSV serves as the primary navigation display, supported by two 15-inch Garmin Chartplotter 8215 units that provide redundancy and multi-station visibility. A Garmin Radar GMR2536 XHD3 with 25-kilowatt power and 96-nautical-mile range mounted on a six-foot open array delivers high-definition target separation and weather detection capability. An Icom M604 VHF radio with integrated digital selective calling ensures reliable communication across all frequencies. Starlink High Performance flat antenna and router provide satellite internet connectivity, a significant upgrade for vessels operating offshore or in remote areas. The Simrad AP-22 autopilot handles extended cruising and fishing station-keeping, while a Danforth Constellation 4-inch compass and MAN digital data panels provide mechanical and engine system feedback. Bennett trim tabs optimize hull attitude across speed ranges, and a Wesmar bow thruster improves low-speed maneuvering in tight quarters. Secondary electronics include a Garmin 740S GPS with seven-inch screen for backup navigation, a rudder indicator for helm feedback, an ACR remote spotlight for night operations, and KVH Trac Phone dome and Trac Vision systems for additional communication and entertainment options. An Icom M59 VHF mounted in the salon provides redundant radio capability, while a Fusion MS-504 amplifier paired with Fusion MS-RA 70 stereo delivers audio throughout the vessel.
Fishing Features
The 510 Convertible's fishing credentials are substantial. Pipe Welders three-times spreader outriggers extend the trolling spread, while an Eskimo E1600 SC ice chipper with insulated transom door and cockpit freezer support extended fishing operations. A transom live well, cockpit sink and tackle station, and transom underwater lights complete the working fishing area. An insulated fish box preserves the catch, and a Bluewater fighting chair with leaning post provides the ergonomic platform necessary for battling large pelagic species. A Water Makers WMS-1000 auto flush system ensures adequate fresh water for rinsing down after fishing, while a cockpit midster system and sunshade protect crew from extended sun exposure during long trolling days.
Comfort and Seating
The salon centers on a forward U-shaped galley to port, appointed with Corian countertops, a two-bay molded sink, and four Sub Zero refrigeration units configured as two freezers and two refrigerators. A three-burner glass Kenyon cooktop with high-gloss cherry cabinetry and Magic Chef microwave provide full galley functionality. Storage extends throughout the galley, with deep cabinetry beneath the sink and additional lockers accessed from the stairwell area. An L-shaped dinette in black leatherette faces the galley across the salon, with additional storage built into the windshield area and overhead cabinets. The entire galley and salon sole is finished in cherry, creating a warm and cohesive interior aesthetic. A Scotsman ice maker mounted in the salon provides convenient ice for drinks and food preservation, while a 110-volt water pump and Head Hunter water pump supply fresh water throughout the vessel.
Cabin and Interior
The interior throughout employs high-gloss cherry cabinetry, creating a traditional yet elegant atmosphere that ages gracefully. Each stateroom includes reading lights, substantial hanging storage, and drawer space designed to accommodate extended cruising. The master stateroom features a new 32-inch Samsung Smart TV installed in 2025, while the VIP stateroom includes a 43-inch model. The guest stateroom's 15-inch Smart TV ensures entertainment options for all accommodations. A Splendid Combo washer and dryer installed in 2025 within a companionway locker eliminates the need for shore-based laundry facilities during extended cruises. Fresh water capacity of 185 gallons supports the three staterooms and galley, while a fuel capacity of 1,040 gallons provides the range necessary for offshore operations and extended cruising.
Power and Performance
Twin 1050-horsepower MAN 2840LE403 engines deliver the reliable power expected of a vessel designed for both cruising and fishing. ZF BW155A.1 transmissions with 1.97:1 reduction ratios manage propulsion efficiency across the speed range. A Kohler 15.5-kilowatt generator with 5,160 hours as of November 2025 supplies electrical power for air conditioning, refrigeration, and entertainment systems while at anchor or cruising. Recent mechanical work in 2025 demonstrates a commitment to long-term reliability. Both engines have completed full 1,000-hour service intervals, with only 35 hours accumulated since completion. Work included complete tear-down and rebuild of all heads with new valves, guides, seals, and gaskets; new water pump housings with complete rebuild and new impellers; gear service; heat exchanger and aftercooler service; new injectors; new thermostats; and new belts. Racor 1000 fuel filters for the mains and Racor 500FG for the generator ensure clean fuel delivery, while an Oberdorpher oil changing system for the port engine simplifies
