Tank capacities — where the figures come from
-
Fuel 40 gal
“Fuel Tank: 40 gal (151.42 liters)” — search excerpt (1994), vessel.yachtbroker.org · “40 U.S. gallons (150 L; 33 imp gal)” — spec database, en.wikipedia.org · “37 gallons of fuel” — search excerpt (1995), boattrader.comA listing and a spec-database copy give 40 gal; another listing (and a listing site's 1985 boat) says 37. No builder figure was found.
-
Water varies by year
“40-gallon aluminum potable water tank (an additional 60-gallon fiberglass tank is beneath the saloon sole)” — review, goodoldboat.com · “95 U.S. gallons (360 L; 79 imp gal)” — spec database, en.wikipedia.org · “Fresh Water: 86 gal (325.55 liters)” — search excerpt (1994), vessel.yachtbroker.org · “85 gallons of water” — search excerpt (1995), boattrader.com · “80 gal capacity total in 2 tanks” — search excerpt (1992), grayandgrayyachts.comWater tanks differ boat to boat (80 to 100 gal in two or more tanks). Good Old Boat magazine's featured boat had 40 + 60 = 100 gal, and Practical Sailor notes integral liner tanks on early boats. No builder figure settles a standard.
-
Holding unknown
“Holding Tank: 16 gal (60.57 liters)” — search excerpt (1994), vessel.yachtbroker.org · “a 16-gallon holding tank” — search excerpt (1995), boattrader.comTwo independent listings (different brokers, 1994 and 1995 boats) agree, and match the 16-gal integral tank in the sister Pacific Seacraft 34's owner's manual. No builder figure for the 37 was checked.
-
Water heater AC + engine · factory option
“some components ... that should be standard on a boat of this quality, like lightning grounding, hot and cold pressure w” — review, practical-sailor.com · “Six gallon hot water heater from engine heat exchanger or shore power.” — broker listing (1998), denisonyachtsales.com · “Six gallon hot water heater from engine heat exchanger or shore power” — broker listing (1998), blueyonderyachts.comPractical Sailor's review says hot and cold pressure water was an option when reviewed. Listings for two different 1998 boats reproduce factory standard-equipment text with a 6 gal heater on engine heat exchanger or shore power, and the builder's late-1990s 34 manual calls heaters standard on all its yachts, so it likely became standard later.
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
No builder list, review or listing mentions a thruster on the Crealock/Pacific Seacraft 37.
-
Stern thruster not fitted
Nothing was found either way; our earlier figure of none appears to be an assumption.
-
Steering varies by year
“with the now-standard steering pedestal in place (the boat was designed for tiller steering)” — review (2000), practical-sailor.com · “Newer boats have wheel steering, but tiller steering was common in the Crealock 37 and in older Pacific Seacraft models,” — review (1989), goodoldboat.comTwo magazines agree the boat was designed for a tiller and early boats (a 1989 example) often had one, while wheel steering on a pedestal later became standard. The changeover year and the pedestal maker aren't stated.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on ballast, draft, deck construction, hp (Yanmar 4JH2E) — left blank rather than guessed.
Built as the Crealock 37 from 1978, by Pacific Seacraft from 1980. Sloop, cutter or yawl; cutter most common. Engines ranged from a 24 hp Volvo in early boats to a 50 hp Yanmar in later ones. Solid hull (balsa/foam hull core was a rare option). Fin keel with skeg-hung rudder; external chainplates.
Engines fitted

Volvo Penta — diesel, single
standard
sailboatdata lists a Volvo diesel for the Crealock/Pacific Seacraft 37 (first built 1978 as the Crealock 37, Pacific Seacraft from 1980) without model or rating; likely the earliest boats.Sources: sailboatdata.com

Universal 5432 (Kubota-based) — 32 hp, diesel, single
standard
SailNet PS37 owners report original Universal 5432 32 hp engines on a 1982 boat and a 1983 boat (hull 151).Sources: sailnet.com
-
Yanmar 4-cylinder 40/44 hp — 44 hp, diesel, single
standard
SailNet owners mention 40/44 hp four-cylinder Yanmars on mid-period boats; search results show a 1990 PS37 with a Yanmar 4JHE 44 hp (listing not read).Sources: sailnet.com
-
Yanmar 4JH2E — 51 hp, diesel, single
standard
A Denison listing for a 2000 PS37 quotes the manufacturer's spec as a Yanmar 4JH2E four-cylinder 51 hp diesel; a Bluewater listing for the same boat gives the 4JH2E as 54 hp. SailNet owners describe 50/54 hp Yanmars.Sources: denisonyachtsales.com · bluewateryachtsales.com · sailnet.com
- Yanmar — 50 hp, diesel standard
-
Beta Marine 38 hp — 38 hp, diesel, single
common repower
SailNet PS37 owners report repowers with a Beta 38 and with smaller Yanmars (32-39 hp) in place of the 50 hp Yanmar.Sources: sailnet.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.
Generator
No builder or review source mentions a generator; one 1998 listing shows a 2500 W generator (likely portable) and another only a wind generator.

Known problems for this model
-
Osmotic blisters on 1980s hulls hull
The same surveyor saw a significant number of blisters on several early-to-mid-1980s 37s, mostly cosmetic but worth addressing; later hulls use a vinylester skin coat to resist blistering.spinsheet.com · practical-sailor.com
-
Aluminum fuel tank in the bilge corrodes fuel
A surveyor reviewing the 37 notes Pacific Seacraft placed aluminum fuel tanks low in the bilge where standing bilge water can corrode them quickly; check tank condition and access.spinsheet.com
-
Cored deck - check around hardware deck
Decks are cored (Practical Sailor describes end-grain balsa with plywood under hardware; a SpinSheet surveyor described plywood core), so moisture-meter the deck around stanchions and fittings.practical-sailor.com · spinsheet.com
-
External 304 stainless chainplates rigging
Chainplates are bolted outside the hull so they are easy to inspect, but they are type 304 stainless; inspect for crevice corrosion at the deck and bolt holes on older boats.practical-sailor.com

-
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
