TIMELESS - Bertram Yacht FOR SALE

The Bertram 450 Convertible is a bluewater sportfish convertible that marries a proven deep‑V hull with the priorities of serious tournament anglers. Interior volume rivals yachts a class above, delivering the poise of a luxury motor yacht while remaining every inch a capable fishing yacht and family cruiser, with confident seakeeping and a notably smooth, dry ride offshore.

A flowing salon–galley–dinette arrangement feels open and purposeful, inviting relaxed downtime or elegant entertaining amid premium finishes and amenities. The guest stateroom is a standout, offering side‑by‑side twin berths rather than the usual over‑under layout. Uncommon in this size range, an elevated cocktail perch forward of the dinette creates a chic social vantage, while the companionway can be configured for a stacked washer and dryer to enhance long‑range cruising ease.

Practicality receives equal attention below decks, where the machinery space is carefully organized for straightforward access and service. The centrally positioned fuel tank stabilizes trim as loads change and serves as an effective buffer to reduce sound and heat reaching the forward accommodations. Clean routing and thoughtful placement of major systems simplify routine care for owner‑operators and crew, underscoring the boat’s tournament‑ready reliability.

Benefiting from numerous upgrades and refinements, this flybridge sportfisher and convertible cruiser presents turnkey appeal for offshore pursuits and refined coastal cruising alike. Trades considered.

Navigation equipment

At the helm, a Raymarine autopilot pairs with a precision compass, a clear multifunction display, and electronic engine controls with a rudder‑angle indicator and odometer to keep you fully in command. Deep‑water intelligence comes from the M265LH depth sounder with CHIRP technology plus a dedicated sonar, while plotting and positioning are entrusted to two Garmin units—GPSMAP 8412SV and 8416—augmented by a third twelve‑inch GPS display in the cockpit and a plotter with a GPS antenna for full redundancy. Communications are handled by a SAILOR RT5022 DSC VHF alongside an additional VHF radio, and a radar with 48 NM range, new in 2025, scans the horizon with authority. A comfortable co‑pilot seat completes this capable navigation suite.

Staging and technical

Anchoring is handled by a 30 kg stainless‑steel anchor on 100 m of 10 mm stainless chain, driven by a LOFRANS 1500 W electric windlass, while bow winches and a powerful bow thruster simplify close‑quarters manoeuvres. Electrical resilience includes new 2022 engine and service batteries and a Mastervolt Charge Master Plus All in One 24/60‑3 battery charger from 2022, with a shorepower connector ready to feed the onboard systems. Safety and bilge management are equally thorough, with a bilge alarm, three electric bilge pumps, an engine alarm, an automatic fire‑extinguishing system, and a fume/gas detector, all backed by an unmistakable horn. Trim and ride are refined by electric flaps and Quick stabilizer fins fitted new in 2025, while deck comforts extend to courtesy lights, a deck shower, a cockpit washbasin, a broad bathing platform with a swimming ladder, and a carbon T‑Top on an aluminium structure, also new in 2025, complemented by Quick underwater lights added the same year. Daily life aboard benefits from a proper entry door, a foldable table in the living room, a draining system, a water pressure pump, a waste‑water purifier plant, and a harbor water connector system that keeps tanks topped up with ease.

Domestic Facilities onboard

Comfort on board is assured by air conditioning and a heater, with elegant interior wooden flooring underfoot and 220 V outlets throughout. The domestic plant features a stainless 80 L warm‑water system, a black‑water tank with a dedicated waste‑water treatment plant, and two RARITAN electric toilets. Power autonomy comes from a Mastervolt inverter 2500V (new 2022), while a new‑for‑2025 watermaker delivers 110 l/h to keep fresh water flowing wherever you roam.

Entertainment

Entertainment is anchored by a FUSION Marine Stereo MS‑RA670 with speakers tuned for open‑water acoustics, while the yacht is fully TV‑ready and boasts a new 50" television in the salon added in 2025 to elevate movie nights and big‑match moments.

Fishing Equipment

For serious trolling, Gibi Marine outriggers—lateral pairs plus a central unit—were fitted new in 2025, transforming the cockpit into a focused game‑fishing command center.

Kitchen and appliances

The galley is culinary‑ready with a two‑burner hob alongside a two‑burner electric hot plate, a SUBZERO refrigerator paired with a SUBZERO freezer, and an ice maker to keep drinks perfectly chilled. A General Electric Power Grill microwave streamlines quick meals, while a washer‑dryer, new in 2025, lightens life on extended cruises and keeps wardrobes fresh.

Upholstery

Upholstery and soft goods are curated for life at sea, with blackout curtains ensuring tranquil nights, generous bow cushions inviting sun‑lounging, protective covers guarding the cockpit, seats, and instruments, and mosquito nets that welcome the breeze while keeping pests at bay.

Additional Information

Additional aboard refinements include a Raymarine tridata, Bennet trim flaps, and smooth‑response electric throttles. In 2022 the bow‑thruster batteries were renewed, complemented by two Vanner Volt Master 60 amp equalisation batteries, while LED interior lighting and a centralized vacuum bring modern convenience. Practical touches such as a cockpit sink and ready‑made provisions for installing a washer and dryer underscore the yacht’s thoughtful, future‑proof design.

Works 2024

In 2024 the yacht benefited from a total polishing of hull and superstructure, a fresh interior carpet, and a complete repaint of the engine room; it also received a new starboard‑side leather sofa and a tasteful recovery of the living‑room upholstery to present an inviting, like‑new ambiance.

Works 2025

The 2025 program elevated both capability and style: a new flybridge bimini and refreshed cockpit sunshade and upholstery were added; Quick Viator stabilising fins were installed; the hull was repainted in ALEXSEAL – Etheral Blue; and a solid teak transom, 9 mm thick, was crafted. Navigation and visibility were strengthened with an additional Garmin twelve‑inch multifunction display in the cockpit, Quick THI QNN 80 W underwater lights, a T‑Top with an aluminium structure and carbon‑fibre top finished with a new Strataglass enclosure, a Garmin radar with 48 NM range, halogen cockpit floodlights, and a Starlink satellite antenna. Handling and angling upgrades included a Yacht Controller remote manoeuvring system and power outlets for electric fishing reels. Fishing hardware rose to tournament specification with forty‑foot outriggers by Gibi Marine, a central twelve‑foot outrigger by the same maker, and two added vertical rod holders. Machinery and electrical improvements comprised a new watermaker producing 100 litres per hour, four new Mastervolt batteries rated at 285 Ah each, a Mastervolt 100 A charger dedicated to bow‑thruster and generator batteries, and two Marco autoclaves, while the main engines had their heat exchangers removed and cleaned and their injectors professionally serviced. Interior fit and finish were upgraded with Corian worktops in the galley and top‑bar featuring scratch‑resistant surfaces, and the running gear benefitted from dynamically balanced propellers (2026).
