Mason 33 Buyer's Guide
The Mason 33 on the used market is a Ta Shing–built, PAE-imported Al Mason design from the mid- to late 1980s, a traditional full-keel 33-foot cruiser aimed at couple-oriented voyaging rather than charter volumes. With low production, surviving boats are encountered through considered searching rather than in quantity, and the marque's detailing rewards a careful look at original construction and later owner additions.
Layouts on the Used Market
Most examples follow the standard interior: a forward owner's cabin with a roomy portside double, settees about a centerline table, a port pilot berth, and a wet-gear locker by the companionway. The galley and opposing nav station serve a teak-heavy, somewhat dark saloon where storage reads larger than the footprint suggests. A deep cockpit with high coamings and enormous lockers is universal, while the small foredeck and CQR-set bow roller define ground-tackle setup. The berthing plan confirms a boat for a couple with occasional young children, not a crowd.
Equipment and Common Upgrades
Commonly fitted boats will show a spinnaker and radar, useful for the downwind rolling tendency and offshore visibility. Often-seen comforts include air conditioning, hot water, teak decks, AIS, and autopilot—the last two speaking to shorthanded passage-making. Less common owner upgrades run to lithium batteries, an inverter, an asymmetric spinnaker, electric winches, or a chartplotter, and a buyer should treat those as individual-boat extras rather than expected kit. Power and energy matter most: standard hot/cold pressure water and two 65-gallon tanks are baseline, but added inverter or lithium setups change liveaboard viability. Canvas and sail handling often grow with an asymmetric and autopilot, while navigation is frequently modernized beyond the original screen-bulkhead station.
What to Inspect
The factory-recommended epoxy coating should be verified, as the company specified a heavier-than-normal isophthalic laminate meant to be protected. Check the iron ballast keel for any sign of sealed-section leakage after grounding, since it was taped and sealed in two pieces to limit rust. Confirm the hull-to-deck joint stainless bars and toerail bolts are intact, and inspect the balsa-cored deck and plywood cabin-trunk backing for moisture. The throughhulls should still carry their nameplates and show reinforced surrounding glass. Engine access demands removing companionway steps and a drawer assembly, so test that process and review the drip pan. Note the lack of any permanent swim-ladder mount; the optional teak ladder is removable and must be stowed underway.
Availability and Buyer's Takeaway
Mason 33s are typically found in the United States and the Netherlands. For a buyer, the checklist is short and structural: verify epoxy protection and keel sealing, confirm deck-core and joint integrity, exercise engine access, and assess whether owner-added electronics and comfort gear match your plans. A sound example is a detailed, traditional cruiser best suited to a couple who prize storage and finish over racing pace.
