Seaward 42 Motor Yacht

Based on Seaward’s Nelson 42 pilot boat hull form, this RCD Category A ocean-going motor yacht is at the top of the Seaward range. Its sea keeping qualities are legendary, making it ideal for extended offshore passage making. It comes with either an aft-cockpit or with an aft-cabin. The latter version has a second outside helm position. David Marsh, Technical Editor of Motor Boat & Yachting, gave the following verdict on the Seaward 42; ‘There are the pretenders, the boats with blue hulls and chunky trawler-like styling that only appear to be serious sea-going boats.  Then there are boats like the Seaward 42, which truly can venture forth anytime in any weather.  The 42 is the real McCoy.’  He refers also to the Seaward 42s ‘….outstanding practical detailing that is clearly the result of obsessive compulsive disorder at work somewhere in the company.’

This fine motor yacht is typically semi-custom built to the individual owner’s requirements or can be produced to the following standard specification:

Design and Build

The Seaward 42 shares its underwater shape with pilot boats and service launches operated by professional users in the UK, Denmark, France, Spain and Italy. It now incorporates an integral stern platform moulded into the hull so that the running length of the hull is maximized, further improving ease of powering, trim, handling and sea kindliness.

A full specification for the Seaward 42 is available on request by emailing us at admin@seawardboat.com

Engines & Stern Gear

The standard supply engines are a pair of Yanmar 8LVs rated at 370hp. Options include the Yanmar 6LY-CRs, rated at 440hp, and the Cummins QSB 6.7’s rated at 425Hp. The engines are controlled and monitored by an electronic shift and electronic monitoring system. The port and starboard gearboxes are arranged for handed rotation, driving outward turning 2” shafts and Seaward’s optimised 24″ 5 blade propellers, reducing noise and vibration and increasing efficiency.

The large heavy-duty rudders, as used on the pilot boats, are in aerofoil section in cast bronze and are operated by hydraulic steering.

Fuel Tanks

Two fuel tanks of similar volume (total approximately 2000ltrs) are integrally moulded into the keel section of the hull. The forward fuel tank feeds the port engine and the aft tank feeds the starboard engine. The tank fillers are located side by side on the port or starboard side deck. These are fitted with special splash stops that prevent fuel spillage when filling up. Optional wing-tanks providing an additional 1,000ltrs are also available.

The fuel supply lines are fitted with an emergency cross connection valve, normally kept shut. In the unlikely event one of the engines should break down, the valve can be opened to enable all the fuel on board to be available to the remaining engine.

Interceptors

Zipwake interceptors with helm control are fitted, providing superior performance than trim tabs.

Fresh Water Tank

The fresh water capacity is 700 litres and is carried in a pair of tanks.
Fresh water is supplied throughout the vessel via an automatic pressure pump with accumulator pump.

Central Heating

An Eberspacher Airtronic 5 air heater is standard on this craft. The air is ducted to outlets fitted in the accommodation areas and heads compartment. An immersion heater is fitted to the calorifier to produce domestic hot water when shore-power is available.

DC and AC Electrical

The craft is fitted with two independent 24-volt battery banks. Battery bank No. 1 is reserved for engine starting and high load items including engine room fans. Battery bank No. 2 is used to supply power for navigation, domestic services and lighting.

Both battery banks have their own battery charging facility via a Victron Multiplus 3000W/70-16 inverter charger.

The battery system includes a parallel switch for emergency use.

The 24-volt circuits are each protected by programmed fuses in the digitally switched electrical distribution system.

Electrical controls for the 240-volt equipment are mounted on an AC panel.

The shore-supply system comes with a galvanic isolator.

Interior Layout

The interior layout comprises a forward guest cabin with ensuite shower and toilet, galley, dinette and wheelhouse saloon.

Interior

The interior is constructed in light oak with a satin finish. Other timbers are available. Interior linings are in the owner’s choice of Macrosuede or vinyl. The interior and exterior upholstery is to the owner’s choice of premium fabrics ( or optional leather ), as is the wheelhouse saloon carpet.

Hatches are Lewmar type throughout.

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.

FORWARD CABIN
The forward guest cabin is designed with a pair of generous size V-berths with sprung mattresses or a double berth. Stowage space is provided under the berths with drop-down door lockers to give access to the space, lined with varnished plywood. There is a pair of lockers above the berths forward with shelves outboard. A large hanging locker is fitted aft to starboard.
Ventilation is by way of opening port lights and a Lewmar hatch on the coach roof. There are five overhead LED lights and a pair of reading lights.

FORWARD WC AND SHOWER
The compartment is accessible from the forward cabin or dinette and is made with easy clean mouldings. The toilet is an electric fresh water flush type with a built-in valve to allow seawater use as an alternative. The toilet pumps out direct to sea. The basin top is in owner’s choice of Avonite material. Shower and basin taps are high quality single lever type. The shower drains to a sump box with automatic pump out. Ventilation is by an opening port light. A large extractor fan is fitted with a suitable timer control.

GALLEY TO STARBOARD / DINETTE TO PORT
The large galley is to starboard. The sole may be finished in a variety of materials to the customer’s choice including specialist wood finishes, laminates and carpet.

The galley uses an electric cooker and a Miele 6022 microwave is also fitted. A double GN Espace Gastronorm A and B sink with accessories is fitted. A suitable fridge and freezer are provided.

The galley worktop is in the owner’s choice of Avonite. All spare space outboard of the worktop and within the galley is utilised as storage for crockery, utensils and provisions. Other options are available for the galley arrangements if preferred.

The main dining area is to port with a large dining table and ample seating for four people. The table is made to lower to form a double berth.

Stowage space is provided under the seating and there are lockers fitted outboard to take odds and ends.

There are six overhead LED lights plus two bulkhead reading lights along with a central red light for use on night passages.

Ventilation is by opening port lights and a Lewmar hatch in the deck head.

WHEELHOUSE (GENERAL)
Unlike many planning hull designs, the Nelson maintains a fairly flat running trim at all speeds. This provides excellent forward vision from the inside helm position. The vision is maintained in heavy weather conditions with commercial type, heavy-duty multi-speed wipers that are included as standard on this craft. The front screens are double-glazed for improved demisting.

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. Great attention to detail is given by Seaward to ensure 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 or similar pilot armchair seats, one to port (helm) and one to starboard (nav), are fitted as standard. The seats are mounted on locker bases arranged for storage.

Hidden/flush headlining panels will be fitted, removable for services access without removing penetrations like vents and curtain rails.

The starboard side of the wheelhouse console shelf is fitted with a navigator’s desk.

An ‘L’ shaped sofa, with stowage within, is fitted to starboard and extends from the aft end of the nav seat to the rear wheelhouse door. The sofa is mounted on a plinth with chart stowage under.

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

Wheelhouse ventilation is by slide-opening clamp-shut front side windows and overhead vents.

Popper covers are fitted to the forward screens, forward side windows and aft door windows. Curtain rails are provided for the aft side windows and the rear window.

ENGINE ROOM
Access to the engine room is via an access hatch, supported by gas struts, on the centre-line of the cockpit. Apart from the main engines and associated ancillaries, this heavily insulated compartment is home to the ship’s batteries, charger inverter and the domestic heating system.

Careful attention will be given to the location of items like engine seacocks and fuel filters for service access. Duplex fuel filters with sea-through inspection bowls are fitted.

 

Aft Cockpit

The user-friendly cockpit is easy to access from the wheelhouse, side decks or integral stern platform via a transom door. Two ‘L’ shaped seats have built-in stowage lockers and a stow-away table arrangement. A central hatch provides access to a large lazarette stowage area.

Fender storage bins are moulded into the port and starboard side decks, adjacent to the cockpit.

Exterior

The hull is fitted with an upper M4 rubber D fender for protection and with rubber spray rails just above the waterline.

The deck layout has been designed with wide side decks and an uncluttered fore deck to give good and safe access all around the boat.

The self-launching anchor stem head fitting houses a stainless steel anchor. Controls for the electric windlass are by deck foot switches on the fore deck and by remote control at the helm position. A bow protection plate is fitted.

All deck fittings and handrails are substantial in size and are manufactured in polished stainless steel. The pulpit, side rails and aft rails are fitted with a 1.50″stainless tubular top rail and 1.25″ uprights.

The standard mast is in white powder coated aluminium. It hinges aft to pass under low bridges.

The surface finish for the side decks is Hempels deck paint. The aft cockpit and stern platform is in Flexiteek, carefully integrated to the hatch openings.
