Catalina 320

1993–2006 · designed by Gerry Douglas (Catalina Yachts in-house) · built by Catalina Yachts

Mid-size Catalina coastal cruiser slotting between the Catalina 30 and the Catalina 36. Designed for coastal cruising, weekending, and club racing. Standard fin-bulb keel plus optional shoal/wing keel, spade rudder, masthead sloop rig, and fiberglass construction — the production Catalina recipe. Roomy interior for the LOA; aft-cockpit.

Check this first — the standard boat has a fin-bulb keel with a shoal or wing keel offered as an option. Draft and ballast distribution both change with it, and so does grounding behaviour — a winged keel that beds into mud is harder to free than a fin. Establish which this hull carries before judging draft limits or stiffness.

This is a general read on the Catalina 320 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.

We grade that listing's own claims against what's known about the class, and flag the gaps a survey would catch. Free, no account. No listing yet? See what the free report looks like (a real one, anonymised), or search for a Catalina 320 for sale and come back with the link.

What the Catalina 320 is known for

Known trade-offs

Age-related quirks to expect

Wing keel option vs standard fin keel — different draft + ballast distribution; confirm before pricing severity: Low affects: all (option)
Perkins M30 / Westerbeke 29B-30B / Yanmar 3GM30F engine variants — verify the installed engine against hull number severity: Low affects: 1993-2006
Original holding tank + sanitation hoses reaching end-of-life by year 25+ severity: Medium affects: 1993-2000
Deck-stepped mast — check deck-core compression under mast step on older hulls severity: Medium affects: 1993-2000

Systems to check before you buy

Engine (Perkins M30 / Westerbeke 29B-30B / Yanmar 3GM30F) priority: coastal, weekending

Engine variant depends on hull number and production year — Perkins M30 on early hulls, Westerbeke 29B / 30B during the mid-1990s transition, and Yanmar 3GM30F on later hulls. Heat exchanger + raw-water pump are typical 25-year wear items.

Standing rigging + chainplates priority: coastal, offshore

Most original wire + chainplates now at or past first re-rig interval (~20-25 years). Chainplate leaks into deck core around shrouds are the recurring class issue.

Deck core + hull-deck joint priority: coastal, offshore, liveaboard

Class-typical Catalina pattern — moisture-meter survey essential. Targeted areas: stanchions, genoa tracks, chainplates, mast step, traveller. Localised repair affordable; widespread coring failure is a project-boat outcome.

Mast step + deck compression priority: coastal, offshore

Deck-stepped mast loads the deck core directly. Compression / moisture in the core under the mast step is a class issue on older hulls. Check deck flex + mast-step bedding.

How it fits your plans

Coastal
Sweet spot. Designed for it. Forgiving sailing characteristics, roomy interior, well-known to surveyors, parts ubiquitous.
Offshore
NOT designed for it. Fin-keel + spade rudder + light displacement + production-grade ballast retention = coastal platform. Significant prep required for any sustained offshore work.
Liveaboard
Workable for two on coastal liveaboard; tankage modest (~25 gal fuel / ~50 gal water typical) — frequent re-provisioning.
Weekending
Excellent. Designed for it.

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 Catalina 320 — 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.
