Tank capacities — where the figures come from
-
Fuel 96 gal
“approximately 363 litres (80 gallons)” — builder (current Neil Marine build), neilmarine.comA single stainless tank under the cockpit floor. The builder's 80 gallons are imperial (363 L = 80 imp gal = 96 US gal). This is the later builder's spec; no document from the original Northshore era was checked.
-
Water unknown
“approximately 340 litres (75 gallons) total” — builder (current Neil Marine build), neilmarine.comNeil Marine's spec gives two tanks totalling 340 L (75 imp gal = 90 US gal); our earlier figure was 96 (likely 80 imp gal from a spec database for the original Northshore boats). Not settled for the Northshore-built boats that make up most of the fleet.
-
Holding unknown
Neil Marine's spec mentions only a gray-water sump, with no holding-tank size.
-
Water heater engine · standard
“Hot and cold water is supplied by pressure pump to outlets in the galley and toilet. Hot water is heated from a calorifi” — builder (Neil Marine builds), neilmarine.comNeil Marine's specification includes an engine-heated calorifier (hot water tank) with pressure hot and cold water; capacity and any electric immersion element not stated. This is the later builder's spec; it may not apply to the original Fairways/Northshore boats.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster unknown
Neil Marine's specification for the boats it builds today, which marks several items as optional extras, lists no thruster, but it isn't a complete option list.
-
Stern thruster not fitted
Nothing was found either way; our earlier figure of none has no source.
-
Steering hydraulic
“A hydraulic steering system consisting of pump and cylinder drives the rudder from a teak steering wheel in the wheelhou” — builder, neilmarine.com · “Emergency steering by tiller in cockpit (a varnished teak tiller is available as an option).” — builder, neilmarine.comThe spec from Neil Marine, which builds the boat today (Yanmar 4JH4 110 hp boats), gives hydraulic steering from a wheelhouse wheel, with a cockpit tiller for emergencies. That doesn't confirm our earlier figure of a wheel in the cockpit; original Northshore-built boats (1977 on) weren't checked and may differ.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on draft, engines, water tank — left blank rather than guessed.
Solid hand-laid hull with encapsulated cast iron ballast, canoe stern, long keel; hull-deck joint through-bolted and glassed over. Ketch standard, sloop optional. Over 100 built in three marks; the Mk III by Northshore from 1995.
Engines fitted
-
Perkins Sabre (Ford-based) — 60 hp, diesel, single
standard
The original Fairways Marine brochure (via sailboatdata) gives a 60 hp diesel without naming the make; Classic Boat's 1978 test boat has a 60 hp Perkins Sabre. Make is from that one boat, so treat as likely rather than confirmed for all early hulls.Sources: sailboatdata.com · classicboat.co.uk
-
Yanmar 4JH3-TE — 75 hp, diesel, single
standard
Classic Boat (2011) gives the Yanmar 4JH3-TE 75 hp as the standard engine of later Northshore-built boats; sailboatdata notes later docs specify 75-80 hp Yanmars.Sources: classicboat.co.uk · sailboatdata.com
-
Yanmar 4JH4-HTE — 110 hp, diesel, single
standard
Neil Marine's current build specification for the Fisher 34 fits a 110 hp 4JH4-HTE (recent production only).Sources: neilmarine.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.

Common problems (1)
-
Mixing elbow failure exhaust
The exhaust mixing elbow on 4JH engines pits and fails, sometimes within a few hundred hours; owners treat roughly 1000 hours as a practical life and inspect the elbow-to-manifold joint for salt weeping.cruisersforum.com · jeanneau.proboards.com · facebook.com
