Remarks :
Built by Seaward Marine and designed by Arthur Mursell, this rugged and capable Seaward 23 features a GRP semi-displacement hull with teak brightwork and twin rudders. Powered by twin Mermaid 56hp diesel engines on shafts, she offers solid performance with Bennett trim tabs for enhanced stability.
Well-equipped for navigation with Raymarine and Garmin electronics, she also includes shorepower, an inverter, and USB charging. The cockpit features ample seating, a teak table, and both summer (new 2024) and winter canopies.
Below deck, there’s a compact galley with hob, grill, microwave, and sink, plus a separate heads compartment with Jabsco toilet and basin. With 210L fuel and 190L water capacity, diesel heating, and reliable systems, she’s ideal for coastal cruising.
