1975–1988 · designed by Walter Schulz / G. H. Stadel & Son · built by Shannon Yachts
Premium hand-laid offshore cutter (ketch option) built in Rhode Island. Heavy-displacement bluewater platform with bronze hardware throughout, designed for seakindly motion and long-distance shorthanded cruising. Walter Schulz personally inspected every hull during the original Shannon era — a level of QC almost unmatched in US production sailboats.
Check this first — the standard boat is a cutter and a ketch was offered. That changes the standing-rigging inventory, the sail wardrobe and the running cost, and it changes how the boat is handled shorthanded — which is much of why a buyer chooses one. Confirm which rig this hull carries before pricing rigging work or reading anything below about sail handling.
This is a general read on the Shannon 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. Use it to know what to look for; for a read on a specific
listing, run a free FairKeel report on that boat.

What the Shannon 38 is known for
Walter Schulz personally inspected every hull during the original Shannon era — Shannon QC reputation is genuinely unmatched among US production sailboats of the same period.
Hand-laid fiberglass + bronze hardware throughout. Build quality is consistently cited as best-in-class for 1975-1988 US offshore production.
Cutter rig design supports progressive shortening — single-hand-able rig management in increasing wind without needing to leave the cockpit.
Strong used-market price retention. A well-maintained Shannon 38 holds value better than most contemporaries of the same LOA — informs negotiation framing (limited downward price flexibility for clean examples).
Known trade-offs
Heavy displacement = slow under power on the original auxiliary engine sizing. Most cruising owners have repowered; an unrepowered original at 40+ years is a project not an asset.
Below-WL access for through-hull replacement requires cabin sole or settee removal on most hulls. Drives up labor multiplier (1.5-2.0×) for any below-WL work.
Premium build = premium pricing both at purchase and refit. Refit budgets need to reflect Shannon-tier parts pricing rather than mass- production-cruiser pricing.
Teak decks (where fitted) are beautiful but a major end-of-life liability by year 30-40 — single largest refit line item if present.
Age-related quirks to expect
Teak deck (where fitted) reaching end-of-life by year 30-40severity: Highaffects: hulls fitted with teak decks
Original bronze through-hulls + seacocks — premium fittings but at 40+ years are at age limitseverity: Mediumaffects: 1975-1988
Ketch variant — mizzen rig + mizzen step add a second standing-rigging cycle and a second mast-step inspection zoneseverity: Mediumaffects: ketch-rigged hulls only
Original engine (Westerbeke or Perkins) — many hulls now on second engine; repower history materially affects valueseverity: Mediumaffects: 1975-1988
Original wire + tangs typically due at 25-30 years. Shannon chainplates are bronze and bolted through bulkheads — the bronze fittings themselves hold up well, but the bulkheads (and the deck penetrations) need inspection for leak history. Keel-stepped mast adds a mast-step bilge inspection.
Original 1976-1990 bronze fittings now at 35-50 years. Replacement on a full-keel hull means cabin sole removal in places for access to the deeper bilge fittings — labor multiplier 1.5-2.0× over a fin-keel equivalent.
Engine (original vs. repower)priority: offshore, coastal, liveaboard
Original Westerbeke or Perkins diesels on most pre-1990 hulls. An original engine at 40+ years should be assumed near end-of-life unless service records prove otherwise. A repowered hull (Beta Marine, Yanmar, modern Westerbeke) is a significant value-add.
Many Shannon 38s were built with full teak decks. By year 30-40 the teak is typically worn thin, bungs lifting, fastener corrosion visible. Re-deck cost is the single largest line item on a teak-deck Shannon refit budget — material to negotiate aggressively if present.
How it fits your plans
Offshore
Designed for it. Heavy-displacement full-keel cutter, bronze hardware, keel-stepped mast — a top-tier US offshore platform of its era. Pardey- class endorsement.
Coastal
Overbuilt for coastal work. Slower than fin-keel boats of the same LOA; not a coastal racer. Owners typically pay a premium for offshore-grade construction they don't fully utilise in coastal-only service.
Liveaboard
Strong. Generous storage, robust hardware, traditional interior joinery. Below-WL access challenging for DIY maintenance (full-keel constraint).
This guide is the class. A report is that hull. Paste the
listing you're looking at and FairKeel grades every claim in it against what's
known about the Shannon 38 — where the evidence is thin, the red flags worth
a second look, the costs likely to land in your first season, and whether the
boat suits the plans you describe in a few short questions.
It won't read the photos or put a number on the boat — that's the $249
Deep-Dive, and for the real answer, a surveyor. It will tell you when a
Deep-Dive isn't worth buying. Free, no account, usually a minute or two.
