Catalina 34 Mk II Sailboats for Sale

Layouts on the Used Market

The Mark II arrived in 1996 with an interior arrangement that had already been well sorted by a decade of owner feedback on the earlier model. The forward V-berth cabin is full and private, separated from the main saloon by a bulkhead, and forms a genuinely usable sleeping space rather than a wedge you crawl into. The main saloon follows a conventional but roomy arrangement: a starboard dinette faces a port settee, with the L-shaped galley placed aft on the starboard side and the head forward to port near the companionway. That head placement — moved aft from the original forward position in earlier Catalinas — doubles as a wet locker and is a genuine convenience on a cruising boat.

The aft cabin, entered through the galley via a door that the cook will tolerate rather than love, offers an athwartship double berth tucked beneath the cockpit. In cooler climates this cabin functions as a comfortable second sleeping space; in warmer anchorages, limited ventilation often relegates it to dedicated storage. The galley itself is a known compromise — counter space is modest, and serious cooks will find it tight — though the overall interior volume consistently draws praise from owners as among the best use of a thirty-four foot hull they have sailed.

Most boats on the used market carry the standard fin keel at around five and a half feet of draft. Wing-keel examples are out there and appeal to sailors navigating shallower estuaries and tidal rivers, but the consensus among active sailors favors the fin for all-around performance. A small proportion of boats turn up with the taller rig option, which adds meaningfully to light-air performance and is worth seeking out if you sail in regions prone to soft breezes.

Equipment and Common Upgrades

Boats on the used market are typically well-equipped by the time they reach a second or third owner. A bimini, dodger, autopilot, and chartplotter are now standard fitments across the overwhelming majority of listings — these items have been added so consistently over the years that finding a boat without them is the exception. Furling headsails are essentially universal, and most boats carry a roller-furling jib in the 155-percent range suited to the lighter conditions of the Chesapeake, the Gulf Coast, and Southern California.

Radar, an inverter, a cockpit shower, and air conditioning appear frequently enough to be considered common rather than exceptional — particularly on boats that have spent their lives in warm-water cruising grounds. Spinnakers and asymmetric kites turn up often, reflecting that many Mark II owners do race or at minimum enjoy downwind sailing. A furling main is a less universal but often-seen addition.

The owner upgrade most commonly praised in community forums is the elliptical rudder extension, which was eventually incorporated into later production hulls and addresses the weather helm that is the design's most discussed shortcoming. On older Mark II hulls that have not yet received this upgrade, it remains a worthwhile improvement to budget for. Three-bladed propellers in place of the original two-blade are another common and sensible addition, smoothing out vibration and improving motoring manners meaningfully. Solar panels, electric winches, a hot water system, and upgraded electronics represent the next tier of owner improvements — present on some boats, absent on others, and each worth factoring into your comparison when evaluating otherwise similar examples.

The Universal M-35 diesel became the standard engine in the Mark II, a four-cylinder unit that runs more smoothly than the three-cylinder M-25 found in the earlier Mark I. Boats on the market are old enough that engine condition, service history, and impeller and heat exchanger maintenance records deserve careful attention regardless of which powerplant is fitted.

What to Inspect

The Catalina 34's fiberglass hull is solid laminate with no core — a construction choice that sidesteps balsa delamination but means the foredeck and cabin sole area can feel somewhat flexible underfoot compared to cored boats of similar vintage. The deck uses a plywood core, and any soft spots or delamination around fittings and hardware penetrations warrant close investigation before purchase. The hull-to-deck joint uses a shoebox method with adhesive and mechanical fasteners; inspect this seam carefully along the full perimeter for separation or weeping.

The companionway hatches are large by design and have been noted as a ventilation and access trade-off on older hulls. Leaky ports were a documented issue on pre-1988 Mark I hulls, and even on later boats the portlights deserve a close look with a flashlight from below during a rain test or with a hose. Wiring on older examples can be disorganized and age-corroded; a full electrical inspection is not optional on any boat of this vintage.

Rudder bearing slop is a recurring theme in long-term owner reports and should be checked by pushing and pulling the rudder at the gudgeons while an assistant watches for play at the tiller or wheel stock. On boats that have not received the elliptical rudder upgrade, the original spade rudder may show wear at the bearings from years of weather-helm loading. The engine mounts on the Universal diesel are known to deteriorate after several decades and are worth inspecting and budgeting to replace if they have not been attended to recently.

The interior fiberglass pan liner that forms the furniture structure is bonded in place and limits visual access to much of the bilge area and inner hull surface. A competent surveyor will use a moisture meter extensively here; osmotic blistering has been documented on older hulls and is worth checking on the topsides and bottom. The chainplates, while they have a good reliability record as a fleet, should be unbolted and inspected for crevice corrosion on any boat that has not had this done in recent years. The LPG locker arrangement on earlier hulls received criticism for limited tank stowage; confirm that any gas installation meets current safety standards.

Availability and Buyer's Takeaway

The Catalina 34 Mark II is among the more widely available coastal cruisers in the North American used market, with concentrations on both the East and West Coasts of the United States and healthy availability in the Great Lakes. Canadian listings turn up consistently, particularly in British Columbia and Ontario. The model is less prevalent in European waters but not unknown, and the active international owners association means that community knowledge is accessible regardless of where you are shopping.

This is a buyer's market in the best sense — enough examples exist that you can afford to be selective and walk away from a boat that does not present well. The combination of a large production run, strong parts availability through Catalina Direct and the owners association, and an extensive collective knowledge base makes the Mark II among the easier boats to own over the long term.

Before making an offer, verify:

• Rudder bearing free-play and condition of the rudder stock seal
• Engine service records, mounts, impeller, heat exchanger, and transmission fluid
• Deck core integrity around all chainplates, stanchion bases, and deck hardware
• Portlight and companionway hatch sealing
• Hull-to-deck joint condition along the full perimeter
• Wiring age, labeling, and condition of battery banks
• Whether the elliptical rudder upgrade has been fitted, or budget for it
• LPG installation compliance and tank stowage arrangement
• Osmotic blister history and any previous professional bottom work
• Documentation status and standing rigging age
