Seaward 39 Motor Cruiser

Seaward 39 Motor Cruiser

The all-new Seaward 39 motor cruiser marks a major step forward in the development of these Nelson type all weather motor cruisers. Fitting neatly within the Seaward range between the 35 and 42, she is the first to have a mid-cabin set beneath the main saloon, and sets new standards in marrying quality build and quiet, vibration free running with Seaward’s exceptional comfort and sea-keeping abilities.

And no wonder. She shares the same underwater shape as the rugged all-weather Seaward pilot boats that service shipping in all weathers in ports from Denmark to Spain. The significant advances in craftsmanship and sound absorption come straight from the world of superyachts where Mike Burnham and Stephen Thomas were previously employed.

“This new Seaward 39 in the latest product in a massive development programme to heighten quality, comfort and ride right across the range.” Says Mike Burnham. Among the innovations to reduce noise and vibration are special isolation for the engines, extensive noise absorbent materials incorporated in the layup of the hull and deck, and a wheelhouse that ‘floats’ on an isolation membrane separating it from the hull and machinery. “We have also made considerable improvements to the interior furnishings by bringing these craftsmanship skills in-house. All electrical installations are now carried out by the in-house team as well. In reality, our boats are now built like small superyachts.” Burnham adds.

Owner David Harland is just as enthusiastic. “This is my 5th Seaward and I’m delighted with her. She is exceptionally quiet – so much so that some of my crew didn’t even realise that the engines were running when we were about to cast off – very spacious, lovely joinery and remarkably smooth in a seaway. Recently after our visit to The Nelson Boat Owner’s Rally, we planned to return to Guernsey on the Tuesday, however it was clear from the forecast that the weather was set to deteriorate so we cut and ran on the Monday afternoon. We experienced a typical Solent chop with the wind against tide and a big breaking swell, as we crossed the Channel. The winds were gusting strong F5 but the boat handled without complaint and maintained a cruising speed of 18 knots, with ease.”

The layout accommodates four in the owner’s suite and mid-section guest cabin. She also has a large well-equipped galley amidships and spacious wheelhouse that doubles as a day saloon and dining room offering panoramic views.

The aft cockpit, which is easily accessed from the wheelhouse and side decks, also has a large table for al-fresco dining, together with a stern platform, which is moulded into the hull to provide a safe and stable boarding point from a dinghy and for swimming from.

Round bilge semi-displacement type with flared bow. Varnished teak (or rubber) spray rails and all around 4″ rubber D fendering compliment the purposeful looks of the craft and provide extra protection when going alongside. Standard colour is Blue.

Deck / Superstructure

This is a G.R.P. moulding with substantial gunwales and wide non-slip decks incorporating a bevelled toe rail.  The superstructure has a large vertical flange that overlaps with a similar flange on the hull before being through bolted and laminated to the hull. Standard colour is White.


The Seaward 39 is available with a choice of twin-screw diesel engine options from the Yanmar 8LV, 370 hp to other models from Yanmar and Cummins.
Each engine is independently installed with its own separate fuel tank and start battery. There are emergency back up connections built in – these are described elsewhere.
Everything about the engine installation is designed with safety and security in mind. The large size seacocks are fitted with external gratings to prevent things like plastic bags blocking the water flow. The seacocks are connected to the engines via large filter pots with see through lids. Smaller items of debris and weed that pass through the gratings can be spotted and removed from the pots before they are able to build up and cause a blockage.
The engine cooling water is discharged through the exhaust systems. The exhausts comprise of 5″ flexible hoses connected to Vetus silencers and then up under the side decks before going down to the exhaust outlet pipes. The exhaust outlet pipes exit in the waterline area on the hull side near the transom. The design of the exhaust layout ensures that the transom and boarding platform areas are kept free of exhaust residue and the exhaust gases are not drawn back into the cockpit area when the craft is under way.

Engine controls
Electronic single-lever engine controls are standard.

Electrical System

The Seaward 39 is fitted with two independent 12-volt battery banks, each comprising of two x 110AH 12-volt Numax XV dual marine sealed batteries wired in parallel. The battery system includes a parallel switch for emergency use

The interior layout (shown on the illustrations) comprises a forward located owner’s cabin, a spacious galley, a spacious shower and toilet, amidships guest cabin, wheelhouse saloon and aft cockpit.
Working from forward to aft, the standard interior layout is as follows: –

Chain locker
A watertight bulkhead in the forward section of the craft forms the chain locker. Access is through a dark tinted watertight hatch in the bulkhead with no internal protrusions. It is possible to see inside the chain locker from the cabin without opening the hatch when the chain locker floodlight is switched on.
The fore cabin is designed with a pair of generous size vee berths with sprung mattresses or with the optional double as shown on the GA. The access door opens outwards and can be left open unobtrusively against the toilet bulkhead. Stowage space is provided under the berths with drop down door lockers to give access to the space below the bunks is which is lined with varnished plywood. There is a pair of lockers above the berths forward with shelves outboard. A large hanging locker is fitted aft on the starboard side (port side in different arrangements.)

Ventilation is by way of a pair of opening port lights and a hatch on the coach roof. The cabin sole is in teak and holly ply. There are five overhead LED lights and a pair of reading lights.

Forward WC and shower
The standard arrangement provides a separate shower and toilet to starboard. The fittings include an electric fresh-water flush toilet, an Avonite basin top and washbasin with single lever mixer tap. The space above the basin top outboard is used to form a locker.
A separate shower compartment features a high-quality shower with single lever mixer tap. The shower tray drains into a sump box fitted with an automatic pump with overboard discharge. Ventilation is by way of an opening port light. An alternative two heads compartment layout is also available.

The no gas galley is to port. Gas cooking is an option. Fittings for the galley include a ceramic diesel fired hob, microwave cooker, double sink/drainer with single lever mixer tap and a built in 47 litre refrigerator. There is also a cutlery drawer and generous stowage for plates and cups outboard. All remaining space in the galley area is utilised for cupboard space. A waste bin is built in. Ventilation is by three opening port lights and a hatch in the deckhead. The sole area in this section is in traditional teak and holly that is both attractive and practical. Other galley arrangements and options are available.

Guest cabin
The guest cabin has twin berths, a hanging cupboards and storage lockers. An opening port light is fitted.

Wheelhouse (general)
Visibility is maintained in heavy weather conditions with heavy-duty multi-speed wipers that are included as standard on this craft. The front screens may be double glazed for improved demisting (optional).

Wheelhouse saloon
Access to the large wheelhouse is via the cockpit through a hinged aluminium door on the port side of the rear bulkhead. The helm console is to port and is specially designed to incorporate the owner’s choice of electronic navigation equipment and the engine monitoring instruments. The starboard side of the wheelhouse console shelf is fitted with a navigator’s desk.

Great attention to detail is given by Seaward to ensuring everything is within easy reach and to provide the most comfortable helming position possible. During construction of the craft, the owner is invited to be involved in the design layout of the helm console.
Two fully adjustable high quality Cleeman pilot armchair seats (or similar) are fitted as standard. The seats are mounted on locker bases arranged for storage, one possibly used for a drinks fridge.

An ‘L’ shaped settee, with stowage within, is fitted to starboard and extends from the aft end of the navigator’s seat to the rear wheelhouse bulkhead. A dining table with a fold-out leaf is fitted.

A sideboard is fitted to port with a built-in bar and bottle stowage. There is also space within for a TV or other equipment chosen by the owner.

Wheelhouse ventilation is by slide opening front side windows, and a half-drop rear bulkhead window.

Hidden/flush (fastmount) headlining panels, removable for access to services are fitted without the need to remove penetrations like vents and curtain rails

Curtain tracks or internal pop on covers are fitted. The wheelhouse sole is carpeted.

Engine room
Access to the engine room is via a hinged self-supporting hatch in the cockpit. Apart from the main engines and associated ancillaries, this heavily insulated compartment(s) is home to the ship’s batteries, inverter and charger and the domestic heating system.

Engine access is provided for regular checks of fuel filters, sea inlets and dipsticks.
Careful attention is given to the location of items such as engine seacocks and fuel filters for service access. Vetus fuel filters are standard on this craft. Duplex filters are available as an option.

Aft cockpit
The user-friendly cockpit is easy to access from the wheelhouse, side decks or stern platform. The stern platform is moulded in and has a door access direct to the cockpit for ease of access. A shaped seat is fitted aft with built-in stowage lockers and a stow-away table arrangement.

Wheelhouse / Cockpit

Access to the wheelhouse is from aft through a single hinged door on the port side of the wheelhouse. The wheelhouse has good all round vision and is arranged with the helm console to port and the navigator’s position to starboard. The helm console is custom designed to suit the engine instruments and navigation equipment. The owner is invited to the factory whilst the craft is being built for a fitting to ensure all the controls, switches, seats and footrests are fitted in their optimum positions. The console area in front of the navigator is flat and will accommodate a folded chart for navigation under way. A navigator’s locker is built into the console shelf for navigation instruments etc. A chart light is provided.Two fully adjustable Cleeman ( or similar ) pilot armchair seats are fitted as standard. The seats are mounted on oak lockers with stowage within, possibly for a drinks fridge in one.
The latest design layout includes an L shaped lounge area with a coffee and dining table aft of the navigator’s seat. The area beneath the settee is available for general stowage and is probably the most convenient place to keep your safety equipment. An oak cabinet sideboard is fitted to port, with a built-in bar and bottle stowage. It is also an ideal location for the optional LCD flat screen colour television or other customer supplied items.
Overhead lights and a central red light for use on night passages provide lighting. Ventilation is by two slide opening front side windows, two half-drop rear bulkhead windows and two overhead vents.
The sole area in the wheelhouse is covered in carpet.

The cockpit is fully self-draining and includes a GRP moulded shaped seating area with soft cushions. The GRP seat bases have hinged lids for access to the stowage areas beneath. A socket is provided to enable the coffee/dining table to be moved to the cockpit area. Entrance from the cockpit to the wheelhouse is by way of a heavy duty hinged door finished in white powder coating.
A full canopy/sun awning arrangement is available on the options list. This comes with side and rear windows and zip up doors for access each side and over the stern. In hot weather the rear can be rolled up and the sides removed to convert the canopy to a sun awning

Exterior and Deck Fittings

The hull is fitted with an upper M4 rubber D fender for additional protection and solid teak spray rails just above the waterline. It is possible to have the M4 rubber in place of the teak spray rails at no extra cost if preferred.
