Sealine 305 Fly now available in online auction. Everyone can place bids until June 22, 2026. Sealine 305 Fly ready for new boating adventures If you’re looking for a Sealine 305 Fly for sale, this classic from 1985 offers a delightful combination of space, visibility, and relaxed handling. This Sealine is built by Fibrasonic Marine in fiberglass and features a hard-chine hull, giving her a pleasant and predictable character on inland waters, lakes, ponds, and rivers. With a length of 9.70 meters and a beam of 3.05 meters, the boat feels spacious while still remaining manageable in harbors and at bridges. The air draft is approximately 4.00 meters, and inside there is a headroom of about 1.95 meters, making life on board comfortable even for taller individuals. Onboard, it’s all about relaxing days on the water and practical amenities for vacations. The accommodation includes a dining area, shower, refrigerator, oven, mattresses, and hot water. The electric toilet does not discharge directly into open water and is connected to a 70-liter holding tank. For drinking water, there is a 100-liter water tank with a pressurized fresh water system that was renewed in 2025. Hot water comes from a 40-liter boiler that can be used both electrically and on shore power. Heating can be achieved with warm air via a 4 kW Eberspächer heater, allowing for an extended season on board. How does this Sealine 305 Fly perform with twin engines? She is powered by two Volvo Penta AQAD30 diesel engines of 110 horsepower each, both inboard and electrically started. With twin engines, maneuvering often feels calmer and more controlled, complemented here by an electric bow thruster. The specified cruising speed is around 15 km/h with a top speed of approximately 35 km/h, making her suitable for both leisurely cruising and more spirited outings. The engine hours are about 1500 per engine. Instruments such as tachometers, oil pressure gauges, temperature gauges, and fuel tank gauges are present to keep track while underway. Is she suitable for overnight stays and vacations? Yes, this Sealine 305 Fly is equipped for multi-day trips. She offers three fixed sleeping places with the possibility of two additional sleeping places. With amenities such as hot water, shower, kitchen setup, and refrigeration, it’s easy to spend longer days on board. Particularly nice is that the galley was renewed by a ship carpenter in 2025, providing the living space with a fresh and practical basis for cooking and living. What about tanks and energy onboard? For diesel fuel, there is a total tank capacity of 175 liters complemented by two plastic fuel tanks of 175 liters from 2025 and an additional plastic tank of 60 liters from 2025 for the heater. Shore power is available onboard along with a battery charger and alternator. There are six batteries with a total capacity of 595 Ah which is convenient for those who like to anchor longer or stay in quiet harbors without relying entirely on shore power. Navigation equipment such as GPS, depth sounder, compass, logbook, and VHF radio are present including a Simrad RS87 VHF radio with dual controls. What equipment enhances her outdoor living? Outdoors she is equipped with features including a bimini top, cockpit tent, exterior canvas covers, outdoor cushions, safety rails, fenders, and lines. The swim platform with swim ladder invites you to dive on warm days while the outdoor shower allows you to rinse off easily. Davits are present for those who wish to bring along a tender later on. Anchoring can be done with a manual anchor winch along with an anchor and chain. An electric bilge pump provides extra security onboard. Are there any points of concern that buyers should know? There is one known point of concern: there is play in the throttle lever of the port engine. Additionally noted is that she has no osmosis or signs of osmosis issues. The boat was last out of the water for maintenance in 2026 with the latest antifouling treatment completed in 2025. Technical documentation is available which is helpful for those who appreciate insight into the installation and technology. This Sealine 305 Flybridge combines the recognizable Sealine profile with practical layout and equipment suitable for leisure boating and vacations. She is an inviting motorboat for anyone seeking a flybridge motor yacht equipped with twin Volvo Penta diesels, bow thruster, heating system, and comfortable living space. Through Boatauction she now has the opportunity to create wonderful days on the water again with a new owner.
