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.
Hull, Deck & Superstructure Construction:
- Basic hull and structure is welded aluminium including superstructure with five full watertight bulkheads.
- Bottom is nominally 12mm aluminium plate, 24mm in mid drying out / grid area, 16mm turn of bilge aft through to rudders.
- Integral aluminium tankage for water and diesel form a double bottom between the middle of the forepeak to the engine room forward bulkhead.
- Four internal water tight doors by Freeman Marine.
- Main deck and swim step watertight doors by Freeman Marine.
- Forepeak hatch and aft deck hatch by Freeman Marine.
- Bomar hatches for ventilation, natural light, and emergency escape with retracting screens and shades.

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 make 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
Engineered for Performance:
- Max speed approximately 13.25 knots @ 2300 RPM.
- Cruising speed 10.5 knots @ 1650 RPM.
- Fuel consumption @ 1650 RPM (10.5kts) seven to eight gallons / 28-32 litres per hour, smooth water, calm wind, clean bottom and propellers, half load.
- Cruising range @ 10.5kts – 6100nm, before safety factors.
- True Engine Hours: 4,501 at 8 September 2022.
- The FPB 78s have demonstrated the capability of using their unique hull shape and power to surf, locked into waves for long periods with no tendency to broach.
Engineered for Efficiency:
- The FPB 78s approach is to deliver carbon neutral capability at anchor, including the running of air conditioning in many cruising environments. This is the result of many factors starting with the reduction of heat load through glazing, window films, window and hatch covers, motorized blinds in the Great Room and extensive EPDM insulation.
- Powered and passive ventilation without opening hatches also play a key role.
- While at anchor, GREY WOLF II’s extensive solar array keeps the house battery bank charged. Underway, the solar array frequently supplies the electrical requirements of the boat without using the alternators (in hot climates).
- The traction battery bank is of sufficient size to carry the overnight loads of air conditioning in the Owners’ and Guest suites (with judicious use).
- The size and dual output capability of the generator allows battery charging while using other high amp 240 VAC consumers that take maximum advantage of generator time when it is needed. The generator is fitted with an auto start
- Underway, the two alternators through the inverters are sufficient to power many of the high amp 240 V consumers.
- This all adds up to fuel savings and maximum operating flexibility.
- The anti-foul – refurbished early 2022 along with the required coding survey works, routine works and replacement fin seals.
- Grey Wolf was surveyed in 2022 for with a full 5-year MCA survey for CAT ‘0’. (She has an inspection by the MCA annually).

- Transmission – ZF280I- 3.0 to 1 reduction with thrust bearings and Cardan joints. The trust bearing have been uprated.
- ZF Mathers smart command electronic shift-throttle controls, at both helms with a tethered remote on Matrix Deck (these have been fitted to allow for the system to be upgraded in the future to ‘Joystick Manoeuvring System JMS).
- There is a simple shift throttle control located in the aft starboard wet locker. This is installed in case of total Mathers Control failure. It controls shift / throttle on both engines. The connections between it and the engine room are normally disconnected to reduce failure risk in the event of a lightning strike.
- The engines are cooled using individual standpipes with strainers above the waterline. Engine raw water strainers can be cleaned without flooding the bilge with salt water. The engines can be easily flushed with fresh water simply by closing the seacock, removing the strainer lid, and running fresh water into the strainer whilst the engine is running.
- Special high dry risers with an Inconel injection elbows reduce the risk of engine back flooding and injection elbow corrosion.
- John Deere J-139 network monitoring systems with Power View displays are in the engine room and on the electrical panel in the Great Room for both engines.
- Strong propeller shaft seals.
- Aquamet type propeller shafts 2.5”.

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. Charging of the bank is accomplished by an array of 10 solar panels capable of roughly 200 Amp output, two engine driven alternators capable of roughly 360 amp output, and 3 Victron 5 KW inverter chargers capable of roughly 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 50 Hz 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.

|Accommodation and Deck Description|
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 in order 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.
