The FPB 78 series has proven to be astonishing in terms of capability, safety and endurance at sea as well as being a fantastic platform for living well. IRON LADY II is #3 of this series and so the last and newest of the FPB 78s. She has been specified for serious cruising by her most experienced owners, and during their ownership has cruised in the Pacific, Chile and into the Antarctic in company with her hull sister GREY WOLF II. With her light and airy interior, with 360 degree vision from the Great Room, comfortable Matrix deck for watch keeping and controlling the yacht and 3 comfortable en-suite cabins plus crew, she is extraordinary and is ready for world cruising, offering recovery from capsize, surfing ability, rugged aluminium build and total steering control.
Engineered for Toughness:
The FPB 78s are the toughest of all the FPBs with a massive upgrade in the already extra strong hulls.
She has five watertight bulkheads and double bottom, which extends 6’5” / 2m forward of the forward accommodation watertight bulkhead to the engine room bulkhead.
The centerline plating is one inch/24mm thick. Outboard of this, from forward of the central water tight bulkhead to the rudders the plating goes to 5/8”/16mm (light green colour in the nearby image). Elsewhere plating is 1/2”/12mm 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 centerline 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:
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.
Matrix Deck Windows:
Engineered for Quiet:
IRON LADY II was conceived from the beginning to be exceptionally smooth running and noise free. This starts with the very thick aluminum plate extending (5/8”/16mm) extending 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 specially engineered with air space, sound dampening visco elastomeric sheet, and sound absorbing foam, and is mounted with isolation material.
Engineered for Maneuverability:
The FPB 78 takes the FPB fleet maneuverability to a new level. The thrust from twin engines against the large rudders with a 42° rudder angle either side of centre and a seven second hard over to hard over time, coupled with a proportional bow thruster make for exceptional close quarter maneuvering 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 – IRON LADY 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 14 solar panels capable of roughly 200 amps 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 or 60 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 so as to draw power directly from the heavy duty battery bank. These includes, among others, refrigeration, lighting, heater fans, ventilation fans, and electronics. This permits the owner to turn off the 240 VAC inverters when they are not required which reduces consumption. IRON LADY II is frequently run with the 240 VAC inverters and alternators off when underway as solar power is sufficient to power the boat. This can save as much as 5 liters per hour fuel burn on the main engines.
110 VAC power is supplied by a dedicated inverter which primarily serves US outlets around the boat including the helm monitors (monitors can also be run on 240 VAC by simply changing plugs).
12 VDC is supplied by one of two 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 in the sale.

The main saloon, is a true FPB ‘Great Room’ with 360 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. 4 zone remotely controlled blinds enhance privacy while at the dock and reduces solar glare and heat load at anchor. A 55 inch TV hides behind the doors behind the chair for entertainment – it can also display the Furuno commercial grade radar.
There simply is nothing comparable. Dimmable LED lighting and rope lights create the perfect ambience at night.
The main deck saloon offers a large fully equipped galley to port with induction cooktop, oven, full size dishwasher, 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.
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 and Iridium GO, along with a galvanic corrosion meter.
The alcove also has a desk with seating, drawer storage, ship’s laptop and Sailor Mini Sat C, all conveniently arranged for management of onboard ship’s system.
The electrical panel end cap houses remote 24 VDC Bus disconnects, salon air con controls, DC refrigeration controls, ventilation fan controls and switches for the Maretron N2K backbone.
The accommodation deck has the owner and guest living areas clustered near the pitch center for maximum comfort upwind.
The owner’s suite 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 Owner’s suite features sink with large vanity area, separate toilet enclosure and a large shower with seating which also doubles as a bath.
The suite also features a portlight with shade, large vertical storage lockers along the port side, a dresser, large hanging locker with storage shelves and loads of drawers under the large berth, and dimmable LED lights and rope lighting.
For security, hand grab bars and provisions for overhead hand lines are strategically placed.
Outside the Owner’s suite is a dedicated space for the Owner’s office leading down the companionway to the forepeak. It features a portlight, iMac, printer and multiple drawers for storage of cruising guides et al. The double doors to the Owner’s suite also open to make this one large area. Enormous lockers line the companionway for all manner of storage.
There are guest cabins aft with heads en-suite including full showers. All toilets in the master 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.
Each guest suite features it’s own head with vanity and sink and full sized stall shower with seat.
Summary of Accommodation Finishes:
Note: Artwork is in included in the sale.
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.
IRON LADY II features a huge forepeak with Asko washer and dryer, storage cabinets over, plenty of storage space for neat organization of critical gear, toys, and, under the aluminum decking, for spares. A forward chain bin with fresh water wash-down and overboard drains holds 300 feet of Grade 43 chain. Air conditioning skids for the forepeak, Master 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. This is an engine room that 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 systems are designed to provide easy access and maintenance.
Aft of the engine room is what the Dashews refer to as the “executive lounge”. This is new in the FPB world and can be developed in many ways.
Aboard IRON LADY II, there is a workshop to port, with drill press, grinder/belt sander, vice, a huge variety of tools, an enormous tool chest, and four foot/1.2m long work bench. There is ample storage area under the floorboards, and aft under the forward section of the swim step to store a majority of the spares board plus various lubricates, and engine oil. Located aft is the massive steering gear and AP pumps and manifolds.
To starboard is a double bunk with a wet head and shower. There is a sink adjacent to the tool chest.
Access is available from the engine room via a watertight door and the deck. The space is both heated and air conditioned.
As you step out of the great room, at the main deck level, there is a large athwartships counter, with sink, electric BBQ and storage under the counter.
The great room sides extend aft and forms a protective vestibule to the Great Room and 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 salon is a wet locker which houses a control for the aft deck winch and winch for the dinghy, emergency controls, overboard bag and cleaning utensils and supplies.
Located to port of the matrix stairs 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.
Aft of this is provision for two dinghies. A 16 foot Swift Aluminum commercial grade aluminum bottomed RIB powered by a 70hp four stroke Yamaha outboard with VHF, GPS Chart, depth, Class B AIS and internal fuel tank is included in the sale. This is stored to port and has bow storage for a Manson anchor with chain and rope rode and storage under the bench seat aft for life jackets and emergency gear. A rear arch has four fishing rod holders and stow-able boarding ladder. To starboard, rotatable davits can be used for a second dinghy.
Dinghy launch and retrieval has been simplified and made substantially safer by minimizing the height to which the dinghy must be lifted. It only needs to clear the chocks before moving it outboard with the boom. When off the boat, removable stanchions with life lines are installed in the sockets which secure the deck.
A 10’’/3.0 m long 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.
Three large lockers are available for storage. The starboard side has the flammables storage area with room for as many as a dozen 5 gallon/20 liter plastic containers.
The centre two house spare hi modulus lines and cordage, the diesel driven crash pump, Brownie Hookah system and shore power cord with pigtails. A large aft tank is located under the Freeman hatch (primarily used for ballasting).
Extending aft, on the hull edge are cassette vertical storage areas where the stainless steel flopper stoppers are carried.
The foredeck has access to the forepeak and also holds the on deck mounted emergency anchor. The lifelines have also been raised for additional security and feature 4 stainless cables instead of the usual three. High stainless grab lines running from the house roof to the foremast providing a means to attach life jacket tethers in boisterous conditions, although there is really no necessity to be on the foredeck while on passage.
