Tank capacities — where the figures come from
-
Fuel 45 gal
“Stainless steel tank, of about 175 litres” — search excerpt (1987), jachtmakelaardijkappers.nl · “Réservoir de carburant: 130 litres (34 gallons)” — search excerpt (1990), xboat.frOnly broker listings were found (about 175 L on a 1987 boat, 130 L on a 1990 boat), which can't correct our earlier figure. Beneteau's heritage page links a brochure and equipment list, but the brochure couldn't be checked.
-
Water 145 gal
“Réservoir d'eau douce: 280 litres (74 gallons)” — search excerpt (1990), xboat.fr · “Tanks with a capacity of 640 litres ... for the storage of fresh water” — search excerpt (1987), dailyboats.comListing figures scatter widely (280 L and 640 L), and none is a builder figure. We kept our earlier 145 gal (about 550 L) pending the Beneteau brochure.
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
A builder equipment list exists but couldn't be checked.
-
Stern thruster not fitted
Our earlier figure of none has no source; the builder equipment list that would settle it couldn't be checked.
-
Steering unknown
Only automatically generated spec sites mention wheel steering; no reliable source was found.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Fin keel with spade rudder; a wing keel (4.5 ft draft) was available. No model-specific problem sources were read.

Perkins 4.108 — diesel, single
standard
sailboatdata lists a Perkins 4-108 diesel as original equipment (45 gal fuel). SailCentral also names the Perkins 4-108 and quotes a 28/50 hp range, which is not explained and may be copied data, so hp is left null. A SailboatOwners member cites the boat's general specifications naming a Perkins 4.108.Sources: sailboatdata.com · sailcentral.com · forums.sailboatowners.com

Common problems (1)
-
Rear main (crankshaft) seal leak engine
The original rope-type rear seal is notorious for leaking and often starts leaking again a few hundred hours after replacement; Foley sells a nylon/Teflon replacement seal meant to cure it, and owners check the crankshaft sealing surface for pitting.foleyengines.com · boatdesign.net · forums.sailinganarchy.com
