Seaward 25 E20 Motor Cruiser

The latest Seaward Nelson 25 E 14 twin-screw all-weather motor cruiser at speed off the Needles

Seaward 25 E20 Motor Cruiser

“Heading out to sea, nothing fazed the boat, and I think she would rise to any challenge…” (Simon Everett, Powerboat & Rib Magazine)

The Seaward Nelson 25 has found favour for many years with discerning motor boat users and ex sailors alike. Now updated with a string of improved features, the latest Seaward 25 E18 is even more practical. The possibility to step aboard after breakfast, turn the keys and be in Cherbourg for lunch with maximum comfort and security will appeal to all those more used to the typical 12-14 hour English Channel crossings. Twin diesel inboard engines on shaft drives are standard on this craft, with a choice of horsepower. The engines are installed completely independently of each other, each with their own fuel tank and electrical system. The  keel and twin rudders and contra-rotating propellers make simple work of negotiating even the most difficult of berths. This amazing manoeuvrability is not just the result of having two engines but is due to a combination of factors unique on a craft of this size and type.

There is a desk locker to starboard and there is a useful teak hanging locker underneath.


The cockpit is fully self-draining by way of drains through the transom fitted with non-return flaps. There is easy access to the engines through the hinged cockpit seats. Access to the steering gear and fuel system is under the aft seat locker that comes with a lift out stowage box.
There are lockers fitted port and starboard for general stowage.
