Seaward 25

< Back to search


The Seaward 25 is a popular semi-displacement motor cruiser, deservedly sought after thanks to its excellent sea keeping, practical layout and high build quality. Ranger is a good example of her class and has clearly been well maintained. Her impressive specification includes twin Yanmar 75hp engines, electric windlass, radar, autopilot, heating, full cockpit cover and more.

Viewing by appointment only at our Essex office on (01621) 785600. 


The cosy cabin has a double vee berth forward with central table which can be dropped to form a double berth with stowage in various lockers and shelves. Aft to starboard is a well designed galley consisting of a Plastimo Neptune two burner gas cooker with grill and oven, stainless steel sink with pressurised hot and cold water supply, folding top to give additional worktop space and good stowage. To port is a separate heads compartment which has a Jabsco marine toilet and moulded basin with pressurised hot and cold water supply. Teak interior woodwork, light grey linings, and navy blue upholstery (upholstery new 2018) combine to create a feeling of traditional high quality workmanship and makes an ideal setting for a couple looking for long weekends away in comfort. Moving aft to the wheelhouse, a comfortable helm and folding navigators chair are complimented by the large, practical cockpit which can be closed off with aluminium folding doors. The cockpit is fitted with port and starboard bench seats and a single bench seat aft. Eberspacher diesel fired warm air heating with outlets in cabin and wheelhouse.

Mechanical Systems

Located below two insulated engine boxes in the cockpit, two Yanmar 4JH2-HTE four cylinder, 75hp diesel engines. Freshwater cooled via heat exchangers. Twin lever controls with electric start. Twin 130L stainless steel fuel. Shaft drive with Ambassador Stripper rope cutters via P-brackets to twin three blade propellers. Twin bronze rudders. Bennett electric trim tabs. Vetus exhaust alarms.

The engines are in good cosmetic condition and have proved faultlessly reliable during current ownership. The engines were removed in 2018 for the engine mounts to be replaced and were given a thorough 1,000 hour service by Yanmar agents, repainted and refitted including the new mounts, skin fittings and one new exhaust elbow. The propeller shafts were replaced in 2021 and fitted with Tides Marine shaft seals and new cutlass bearings. The engines were last serviced (including new turbo unit) in October 2023 and are currently reading just under 1,450 hours total run time.
