Cabo Rico 38

1977–2008 · designed by W.I.B. (Bill) Crealock · built by Cabo Rico Yachts (Fibro Technica S.A.)

Crealock designed the 38 as an uncompromising offshore cruiser — heavy displacement, long modified full keel with cut-away forefoot, cutter rig — prioritising seakeeping and crew safety over speed. The result is a boat with a legendary reputation for soft motion in a seaway and predictable behaviour in severe conditions. It targets serious bluewater couples or small crews planning extended ocean passages rather than weekend coastal racing.

This is a general read on the Cabo Rico 38 class — informed background, not a verdict on any individual boat. Condition, refit history, and how a particular hull was sailed and stored matter far more than class reputation.

What the Cabo Rico 38 is known for

Exceptional seakeeping — soft motion, non-stalling keel-hung rudder, and cutter rig that allows easy sail reduction make this one of the more confidence-inspiring offshore cruisers of the era.
Construction quality (when original stainless is replaced) is robust — thick fiberglass laminate, solid structural grid, and heavy displacement translate to genuine structural longevity.
Joinery and interior finish are premium for the class and era — all-teak interior with craftsmanship that holds up aesthetically and structurally over decades.
Cutter rig with true two-forestay setup gives offshore versatility — the boat carries a removable inner forestay for a staysail in heavy air, and can be balanced in a wide range of conditions without resorting to a full main.

Known trade-offs

Light-air performance is poor — D/L of 375 and a modest SA/D of 16.3 mean the boat is slow in anything under 12 knots of true wind, especially laden for cruising.
Era-specific stainless steel defects (late 1980s to early 1990s hulls) create serious chainplate and rudder-post risk — a surveyor who does not probe this specifically can miss a latent failure.
Teak deck over balsa core is a known cost trap — any hull retaining an original teak deck warrants sounding every square foot and treating any delamination as a budget line, not a cosmetic issue.
Parts for original Perkins 4108 engines are increasingly scarce and expensive; any engine-related negotiation leverage should be exercised upfront, with repower budgeted as a near-term probability on older examples.

Age-related quirks to expect

Osmotic blistering — polyester resin hulls Medium 1977–early 1990s

Poor-quality stainless steel supplied to factory — rudder posts, chainplates, bow rails prone to corrosion and cracking High late 1980s–early 1990s

Teak deck overlay over balsa-cored deck — core rot if fastener seals fail Medium 1977–2000s (any hull with original teak deck)

Cockpit sole plywood layer susceptible to rot Medium earlier hulls, approx 1977–late 1980s

Iron ballast (7 castings in keel cavity) — early and mid-production hulls; lead used only in last ~40–60 boats Low 1977–approx 2000

Systems to check before you buy

Chainplates and standing rigging priority: offshore, coastal, liveaboard

Late-1980s to early-1990s hulls received substandard stainless steel from the factory. Chainplates on these boats are a known failure point — inspect for crevice corrosion, elongated fastener holes, and any deck weeping at the chainplate covers. Budget for full replacement on any hull where provenance is unclear.

Balsa-cored deck and teak overlay priority: offshore, liveaboard, coastal, weekending

Deck core rot is the most common and expensive structural defect on this class. Boats with original teak overlay are highest risk — any failed seam or fastener over balsa allows water ingress. Tap the full deck systematically; pay close attention to hardware mounting points and around the mast partner.

Hull osmosis (pre-vinylester hulls) priority: offshore, coastal, liveaboard

Pre-mid-1990s hulls used straight polyester resin and are blister-prone below the waterline. Mid-1990s onward the builder switched to vinylester in the outer laminate layers — confirm which resin era applies to the specific hull before purchasing. Look for pitting, bubbling, or evidence of a previous barrier coat repair.

Engine — Perkins 4108 / Westerbeke / early Yanmar priority: offshore, liveaboard, coastal

Original Perkins 4108 engines are now 30–45 years old and parts are increasingly scarce. Westerbeke-equipped boats have a mixed reliability reputation. Assess hours, service history, impeller and heat-exchanger condition, and transmission. A repower (Beta 43 is a common fit) is a realistic budget line for any engine over 4,000 hours or with unknown history.

Cockpit sole and keel-cavity iron ballast priority: offshore, liveaboard

Earlier cockpits used a plywood sub-layer that can rot if water has entered through drains or fasteners. Separately, iron ballast castings in the keel cavity can corrode and swell — inspect for any cracking of the keel fairing, rust weeping at the garboard, or evidence of previous resin fills. Only the last ~40–60 hulls carried lead ballast.

How it fits your plans

Offshore: One of the stronger choices in this displacement range for extended offshore work. The full keel and cutter rig give predictable, confidence-inspiring behaviour in severe conditions; owners consistently report soft motion and a rudder that does not stall. Speed is the honest trade-off — D/L of 375 means passages take longer than lighter-displacement contemporaries.
Coastal: Competent but overbuilt for the mission. The full-keel draft (5 ft) limits shoal-water access, and light-air performance is mediocre when not loaded for passage. Buyers doing primarily coastal sailing should question whether the weight and draft suit their specific waters.
Liveaboard: Well-suited. The joinery and layout quality are among the best of the era — all-teak interior with no visible fiberglass below. Headroom and storage are reasonable for a 38-footer. Two layout options (V-berth Plan A, offset double Plan B) give genuine choice; Plan B is preferred by liveaboards.
Weekending: Functional but not ideal. The boat rewards experienced crews comfortable with a cutter rig. Weekend sailors who want speed and easy single-handing may find the full keel and heavy displacement frustrating in light conditions.
Racing: Not relevant to this class. The design was not intended for racing and will not be competitive in any PHRF fleet.
Motor: Not a motoring-oriented boat. The 5 ft draft and heavy displacement (21,000 lb) mean fuel burn under power is meaningful. Engine reliability is the primary motoring concern given the age of original Perkins or Westerbeke installations.
