Seaward 35 E20Motor Cruiser
“The sea conditions through which we pushed the Seaward 35 would have forced most other boats of a similar size, and indeed many larger craft, down to a crawl.” – (Motor Boats Monthly)
The new Seaward 35 E20 is an updated design based on the well-proven Nelson 35 pilot boat hull. Seaward commissioned the Nelson designer TT Boat Designs to create a completely new superstructure layout that would enable the interior of the hull to be utilised for the needs of the cruising yachtsman. The end result is a vessel that not only provides sleeping accommodation for up to six, but she is also amazingly easy to manoeuvre and moor with only two people on board.
After testing the Seaward 35 in overfalls off Guernsey, the Motorboats Monthly boat test confirmed the seakeeping qualities when they wrote: ‘The sea conditions through which we pushed the Seaward 35 would have forced most other boats of a similar size, and indeed many larger craft, down to a crawl. Worse, their occupants would have been turning green with seasickness or white with fright. For us these are perfect test conditions. Perfect that is if you are in a boat built for the job’.
This specification describes the standard layout and items of standard equipment for the two new versions of the craft. The main difference between the two is that the ‘Cockpit’ version has a single helm position inside, whereas the ‘Aft Deck’ version has dual control with helm positions both inside and outside. As with all Seaward boats, these vessels are also available custom built with other layout possibilities and different equipment fitted according to the owners wishes, within the design limitation of the craft.

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.
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 35 has a proper engine room that is self-contained below the wheelhouse sole. Easy access for routine checks and service is through a hinged hatch in the sole. The whole of the compartment is well insulated including under the engines. This compartment also contains the vessel’s batteries and seawater filters. Ventilation for the engines is by a series of large GRP shell type vents fitted to the sides of the structure. Three engine room lights are provided; these are switched on/off from the helm switch panel.
In the unlikely event an engine has to be removed the whole of the wheelhouse sole can be removed and then taken out via the rear door.
The Seaward 35 is available with a choice of twin-screw diesel engine options from Yanmar or Cummins in the power range 260 hp to 370 hp with appropriate hydraulic reverse reduction gearboxes.
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.
Electronic single-lever engine controls are standard.
Outside helm/aft deck version
The outside standing helm position is offset to port and raised above the deck level with room for a second person or navigator to stand alongside the helmsman. Standard equipment fitted to the outside helm console includes: –
• Helm pump with stainless wheel
• Electronic engine controls
• Engine makers flybridge panel
• Start and stop switches
• Horn switch
• There is ample room on the console to install repeaters for chart plotter/radar, autopilot and Tridata as required.
The arrangement includes a stainless steel tubular retainer rail with hinge up section. The rail provides something for the occupants to lean against when under way. There is the option of having this rail and the rail surrounding the aft deck, to be made in teak with varnish finish.
The gantry mast is part of the windscreen on this version. The standard cover supplied with the craft fits over the windscreen and wraps around the legs of the mast before encompassing the whole of the rear end of the wheelhouse. A zip up rear entrance, offset to port, is included to give access to and from the wheelhouse with the cover in place. Other designs of cover or canopy/awning arrangements are available on a custom design basis.
Two independent banks of 12-volt batteries are installed. One battery bank is reserved for the engine starting and some electrical items that are only used when under way, whilst the other battery bank is reserved for the lighting and domestic equipment. In the event one battery bank is flat when you come to start the engines, the whole system can be instantly put in parallel by a push button switch at the helm console.
A Victron inverter/charger is available as an option; this system will provide 240 volts from the ships batteries for microwave and ring main when shore power is not available and will act a powerful charger when plugged into shore power.
The Seaward 35 uses digital switching which brings all of the power and convenience of advanced home automation to your boat; it allows you to control onboard electrical and electronic systems like lighting, air-conditioning, navigation lights, wipers, horns, entertainment systems, security systems and much more from your network-connected multifunction display, smartphone or tablet.
Digital Switching replaces the standard mechanical circuit breakers and switches with a state-of-the-art digital power distribution. This system not only offers convenience and ease-of-use, it also delivers on the promise of seamless, reliable operation as well as simple and cost effective installation.
Electrical equipment includes:
• Navigation lights
• Anchor light
• Cockpit floodlight
• 16 LED overhead interior lights
• 4 reading/bulkhead lights
• 2 Red lights for night vision
• Chart light
• 12 volt power socket
• Fresh water pressure pump

The standard interior layouts are shown on the enclosed drawings (these show some items that are on the optional extras list) and includes the following: –
The no gas galley is in the mid section of the craft. 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.
The main dining table is situated opposite the galley with ample seating for four persons on a pair of forward and aft facing double seats. Stowage lockers are fitted outboard of each seat for general items and there is an open fronted locker outboard of the table for books or general stowage.
The area below the table is on a raised plinth. The lower part of the plinth includes a chart drawer suitable for full size admiralty charts.
When required, the dining area will convert to form a double berth. Lowering the table and placing the backrest cushions on top make this up. The table can be utilised for chart work when planning those far off voyages.
Standard lighting includes four overhead lights plus two bulkhead reading lights along with a central red light for use on night passages.
Ventilation is by four opening port lights and a Bomar hatch in the deckhead.
The sole area in this section is in traditional teak and holly that is both attractive and practical.
A watertight bulkhead in the forward section of the craft forms the chain locker. Access is through a Bomar watertight deck hatch in the bulkhead. A light is fitted inside the locker to enable viewing inside without the need to open the hatch. The switch for the chain locker light is located in the forward cabin.
Shower / washroom
The standard arrangement provides a dedicated shower/wash room to port. The fittings include an Avonite worktop, wash basin with single lever combined shower mixer tap. The space above the worktop outboard is used to form a locker. A hinge up teak slatted shower seat is fitted on the forward bulkhead. 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 and a tannoy vent in the deckhead.
The toilet compartment is to starboard and includes a hand basin with hot and cold water supply via a single lever tap set in an Avonite worktop. A locker is fitted outboard. The standard manual pump toilet arrangement comes with inlet and outlet seacocks. Ventilation is by way of an opening port light and a tannoy vent in the deckhead. There are various other toilet options available including: holding tank system, electric pump toilet and electric fresh water flush toilet – see options list.
The forward cabin (or owner’s cabin) is designed with a pair of V berths fitted with a pair of fully sprung mattresses. The layout includes a hanging locker to starboard, two tilt type stowage lockers on the inboard side of the berths, a built in stowage locker at the head of the port berth and lockers to port and starboard outboard above the berths. Ventilation is by way of a pair of opening port lights and a Bomar hatch on the coach roof. The cabin sole is in teak and holly ply deck. Three overhead lights and two bulkhead reading lights are provided. Access to the forward cabin is through a passageway between the shower room and toilet. The doors are fitted in such a way that they are dual purpose with latches to hold them open as well as closed. With both doors latched in the open position the forward cabin is completely separated from the dinette area each with separate access to the toilet and shower.
Access to the wheelhouse is from aft through a single hinged door (double doors and down one step on the aft deck version) 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.
An identical seat is fitted to starboard for the navigator. 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.
The latest design layout includes an L shaped lounge area with a coffee table aft of the navigator’s seat. The seating area is enlarged when the navigator’s seat is tilted forward. The settee can be made to form a double berth or two bunk berths on the cockpit version. The area beneath the settee is available for general stowage and is probably the most convenient place to keep your safety equipment. A oak cabinet with sliding doors is fitted opposite the lounge area and is an ideal location for the optional LCD flat screen colour television. A pair of oak lockers form the base for the helm seat and is built to include a slide out tray for bottle and glass stowage.
Six 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 (on cockpit version only), two overhead vents and the rear door (described elsewhere). The sole area in the wheelhouse is covered in carpet.
Cockpit (cockpit version only)
The cockpit is fully self-draining and includes a GRP moulded U 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 aluminum hinged door finished in white powder coating.
A tonneau type cockpit cover is supplied as standard. The alternative of 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.
Seaward Boats come with a comprehensive standard specification. Optional extras enable you to customise your vessel if you so wish. We are able to supply and install most types of Raymarine electronic navigation aids and safety equipment.
Seaward are always pleased to discuss any non standard requirement P.O.A.
Exterior and deck fittings
The exterior of the vessel is in traditional Seaward/Nelson style with a 4″ size rubber ‘D’ fender fitted all round with teak spray rails – teak badges are optional.

The pulpit has a thick tubular top rail and a thinner tube at the mid height down each side. An inboard pilot rail system is available according to the customer’s preference at no extra cost.
A good size uncluttered foredeck and wide low profile side decks makes mooring up a safe and pleasurable experience on the Seaward 35 – an important consideration for husband and wife cruising. In fact it would be difficult to make stepping on and off easier.
Standard colour for the hull is Oxford blue with a white bootop and a white superstructure. The underside of the hull is coated with a solvent free epoxy system before the application of red antifouling. Decks and cockpit sole are coated with Hempel grey non-slip deck paint or teak decking (at extra cost) according to owner’s specification.
