First commissioned 2017, FPB 78 #2 was built to and is maintained to MCA Category 0 including all the MGN labour conventions regulations. The last word in 4-wheel drive explorer motor yachts, in her current ownership she has steamed through the Pacific, cruised in Chile, the Antarctic, and many points between. She has circuited the planet so far about 1.5 times. Maintained to exacting standards with an epic oak interior and with great accommodation for six guests and four crew, she offers bluewater cruising with no limitations.

Engineered for Toughness:

The FPB 78s are the toughest of all the FPBs with a massive upgrade in the already extra strong hulls. With five watertight bulkheads and double bottom, which extends 6’5” / 2m forward of the forward accommodation watertight bulkhead to the engine room bulkhead.

The centreline plating is one inch / 24mm thick. Outboard of this, from forward of the central watertight bulkhead to the rudders the plating goes to 5 / 8” / 16mm (light green colour in the nearby image). Elsewhere plating is ½” / ½12mm to above the chine waterline (pink colour). The topsides are 8mm. There is a collision bulkhead five feet / meter and half-aft of the bow. A stem-bar extends off the centreline girder in this collision containment area. This stem-bar is 1.75” / 40mm thick and 10” / 250mm deep. It and the topsides in this area are supported by five horizontal stiffeners (breast-hooks) which extend aft into the forepeak as topside stiffeners.

Hull frames in forward forepeak are closer together than other FPBs and the topside stiffeners are overbuilt. As a result of the size these they double as shelves.

Window Construction:

Window glass supplied by Bent Glass Design and glued in place with wide flanges. 12mm threaded, welded inserts are placed in each corner for use during installation. These inserts can also be used to hold storage covers in place.

Engineered for Quiet:

GREY WOLF II was designed from the beginning to be exceptionally smooth running and noise free. She had further build modifications to improve noise levels. This starts with the very thick aluminium plate extending (5 / 8” / 16mm) under the engines and over the propellers. Close framing in the way of the propellers further reduces natural harmonics.

The use of thick EPDM foam for normal hull and deck insulation contributes to sound absorption. The fire control insulation in the engine room covers both bulkheads, hull sides, and the deck to reduce the amount of noise leakage. The air intake and exhaust vents are lined in EPDM foam and baffled to reduce noise on deck.

The engine exhaust systems include both Centrek aqua lifts and mufflers, the latter including special remixing chambers that reduce the tendency for gas and water to separate. The generator also has a gas water separator to quiet the normal generator discharge noise.

Each interior bulkhead, beginning with the forward face off the engine room bulkhead is especially engineered with air space, sound dampening Visco Elastomeric sheet, and sound absorbing foam, and is mounted with isolation material.

Engineered for Manoeuvrability:

The FPB 78 takes the FPB fleet manoeuvrability to a new level. The thrust from twin engines against the large rudders with a 35° rudder angle either side of centre and a seven second hard over to hard over time, coupled with a proportional bow thruster, hydraulic stern thruster makes for exceptional close quarter manoeuvring capabilities.

Spring line cleats mean that aft and forward spring lines can be powered against to pull the boat onto the dock. Two Lewmar 64 electric self-tailing winches, one forward and one aft can be used for both dock lines and kedging. The anchoring bowsprit is also designed to be pressed against pilings or the dock and in the most adverse conditions, it often works to bring the bow in at right angles, and to hold her against the dock with the propellers whilst the boat is winched onto the dock.

System Overview – GREY WOLF II has 240 VAC, 110 VAC, 24 VDC and 12 VDC electrical systems. The backbone of the system is the 24 VDC system, which consists of a 1,650 Amp hour battery bank (batteries replace 2024). Charging of the bank is accomplished by an array of 10 solar panels capable of 200 Amp output, two engine driven alternators capable of 360-amp output, and 3 Victron 5 KW inverter chargers capable of 360 amps charging via either shore power or the generator.

The inverters also draw power from the battery bank and provide 240 VAC power at a default frequency of 50 Hz. When connected to shore power or generator, the inverters match the frequency of the source – either 50 or 60 Hz. The generator provides power at either, but normally is run at 50 Hz to save fuel. All high amp ship’s systems run on either 50 or 60 Hz without any modification. This includes the air conditioning, watermaker, washer and dryer and similar. The inverters also will support sources of 240 VAC by supplying additional power from the battery bank when demand exceeds the available supply.

Most ship’s systems, to the extent practical, run on 24 volts to draw power directly from the heavy-duty battery bank. These include, among others, refrigeration, lighting, heater fans, ventilation fans, and electronics. This permits the shutdown of the 240 VAC inverters when they are not required which reduces consumption. GREY WOLF II is frequently run with the 240 VAC inverters and alternators off when under way, as solar power is sufficient to power the boat. This can save as much as 5 litres per hour fuel burn on the main engines.

110 VAC power is supplied by a dedicated inverter, which primarily serves a number of US outlets.

12 VDC is supplied by one of 2 x 24 to 12 VDC converters. 12 VDC can also be obtained from a centre tap on the house bank.

There are also dedicated 24 and 12 VDC chargers for the engine start and generator start batteries. A centre tap and parallel switch on the main 24 VDC battery bank serve as additional backups.

Full, as built, electrical system drawings in paper and electronic formats are available.

Main Deck (Interior):

The main saloon is a true FPB Great Room with 280-degree vision. It is a light and airy place for entertaining, cooking, relaxing, watch keeping, and living within the marine environment. The lower helm mirrors the upper helm layout for ease of operation. Remotely controlled zoned blinds enhance privacy while at the dock and reduce solar glare and heat load at anchor. A 55” TV hides is concealed behind doors (this is on a lift and can be used up or in its stowed position for entertainment – it can also display the Simrad plotter and commercial grade radar imagery).

There simply is nothing comparable. Dimmable LED lighting and rope lights create the perfect ambience at night.

A curtain can be put across behind the watch keeper’s position to stop light pollution on watch if the Great Room is in use.

The main deck saloon offers a large fully equipped galley to port with induction hob, oven, 2 x ½ size dishwashers, an incinerator, loads of storage, upright refrigeration and two under counter freezers with LED lighting. Counter seating for two is available for both eating and supervising the chef. A curtain can be deployed to provide privacy for the guests from the galley area.

In the aft starboard corner of the Great Room there is an alcove with the main DIN rail AC and DC electrical switch panels, genset start and stop, engine monitors, inverter controls, battery monitor, DSM Monitor, SSB with Pactor modem Navtex, Iridium Pilot, Iridium GO, A120 Aircraft Radio and Iridium GO, along with a galvanic corrosion meter.

The alcove also has a desk with seating, drawer storage and Sailor Mini Sat C, all conveniently arranged for management of on-board ship’s system. There is also a PC for Sail mail and Predict wind Weather forecasts.

The electrical panel end cap houses remote 24 VDC Bus disconnects, saloon air conditioning controls, DC refrigeration controls, ventilation fan controls and switches for the Maretron N2K backbone.

Accommodation Deck:

The accommodation deck has the owner and guest living areas clustered near the pitch centre for maximum comfort upwind.

The owners’ stateroom has a magical mix of comfort, security, and visual ambiance. A wonderful spot to curl up with a book if you want to escape, and lovely to be in as you fall asleep.

The owners’ stateroom features sink with large vanity area, separate toilet enclosure and a large shower with seating which also doubles as a bath.

The cabin also features a portlight with shade, large vertical storage lockers along the port side, a dresser, large hanging locker with storage shelves and lots of drawers under the large berth, with dimmable LED lights and rope lighting.

For security, hand grab bars and provisions for overhead hand lines are strategically placed.

The berth can be split into 2 single berths with a lee cloth to divide the berths.

Outside the owners’ stateroom there is a dedicated space for use as the owners’ office leading down the companionway to the forepeak. It has a portlight, printer and multiple drawers for storage of cruising guides and other documents and data. The double doors to the owners’ stateroom also open to make this one large area. Enormous lockers line the companionway for all manner of storage.

There are port and starboard guest cabins aft with en-suite heads including separated full sized shower stalls with seat. All WCs in the owners’ stateroom and guest suites are Raritan Atlantes macerating freshwater heads, so no more vacuum system issues.

The Guest suites feature large berths, under berth drawers for storage, portlights with shades, vanity area with mirror, hanging locker, cupboard, and drawer. The Port guest cabin has a pipecot.

Summary of Accommodation Finishes:

Note: Artwork is in included in the sale apart from the owners’ stateroom view of St Peter Port

The companionway also features a port side systems room that houses the autopilot black boxes, fuel transfer manifold, Maretron system black boxes, hydraulic crash pump and manifold, bilge pump, house battery ventilation fan and cofferdam with access to the port side stabilizer. Access to the starboard side stabilizer cofferdam is under the stairs. Also located in the companionway is a linen cupboard and panel housing the main DC bus disconnect breakers.

GREY WOLF II has a huge forepeak with storage cabinets above and plenty of storage space for neat organization of critical gear, toys, and, under the aluminium decking, for spares. A forward chain bin with freshwater wash-down and overboard drains holds 300 feet of Grade 43 chain. Air conditioning skids for the forepeak, owners’ stateroom and Great Room are located here with easy access for service as are the Headhunter potable water pumps.

Aft of the guest staterooms is the walk-in engine room. It is an engineer’s dream and the sophisticated owner’s pride and joy. It is accessible from aft deck and aft starboard head.

Things to Note:

All GREY WOLF II’s systems are designed to provide easy access and maintenance.

Aft of the engine room is what the Dashew’s refer to as the “executive lounge”. This is new in the FPB world and can be developed in many ways.

Aboard GREY WOLF II, there is a workshop, vice, a huge variety of tools and an enormous tool chest. There are ample storage areas under the floorboards, and aft under the forward section of the swim step where most of the spares board plus various lubricants, and engine oil are stored. Located aft is the massive steering gear and AP pumps and manifolds.

Main Deck (Exterior):

As you step out of the Great Room, at the main deck level, there is a large athwartships counter, with sink, electric BBQ and under counter storage.

The Great Room sides extend aft and forms a protective vestibule with stairs to the Matrix Deck.

The area under the stairs to the Matrix Deck is enclosed and houses the compactor and life raft.

Adjacent to the door to the saloon is a wet locker which houses a control for the aft deck winch and winch for the dinghy, emergency controls, overboard bag together with cleaning utensils and supplies.

To port of the Matrix stairs there is an enclosed day head with Raritan Fresh water manual WC. It also houses the refrigeration compressors which are both fan and raw water-cooled.

2 x Extra electrically operated winches

Dinghies:

Aft of this is provision for two dinghies.

A 10’’ / 3.0 m boarding / swim platform extends aft from the main deck. The entire swim step has been raised 50 mm and belting has been added around the perimeter to reduce over-wash and to add protection.

There are 3 large lockers are for storage. The starboard side has the flammables storage area with room for as many as a dozen 5 gallon / 20 litre plastic containers.

The centre 2 lockers house spare hi modulus lines and cordage as well as the shore power cord with pigtails. A large aft tank is located under the Freeman hatch (primarily used for ballasting) as part of the MCA MGN 280 Cat ‘0’ ballasting.

There is a further hatch for access to the rear hydraulic thrusters with more storage.

Extending aft, on the hull edge are cassette vertical storage areas where the stainless-steel flopper stoppers are stowed.

The foredeck has access to the forepeak and holds the on deck mounted emergency anchor. The lifelines have also been raised for additional security and feature 4 x stainless cables instead of the usual 3. High stainless grab lines running from the house roof to the foremast provide the means to attach life jacket tethers in boisterous conditions, although there is really no necessity to be on the foredeck whilst on passage.
