Design and Construction
Van de Stadt's hand shows in a hull tuned for both coastal and inland passages. The Trintella 53 carries a pivoting lifting keel — a centerboard arrangement that lets her trade deep draft for shallow water when the board is raised, yet keep a seaworthy profile offshore centerboard keel that is a pivoting lifting keel. With the board down her loaded draft sits at roughly 5.58 to 5.88 feet, which lets her into most marinas draft is just about 1.70 - 1.80 meter. The hull itself is solid fiberglass, and the builder paired a lead ballast of about 15,400 pounds against that displacement for a ballast ratio near 31 percent. A length-to-beam ratio of 3.50 and a displacement-length ratio of 214 place her firmly among heavy, volume-oriented cruisers rather than light racers.
Rig and Handling
The ketch rig splits sail area for manageable handling, and the running-rig dimensions give a clear picture of her scale: jib and genoa sheets run about 53.9 feet at 5/8-inch diameter, the mainsheet spans 134.8 feet, and spinnaker sheets reach 118.6 feet, all on 5/8-inch line guiding dimensions of running rig. Her sail-area-displacement ratio of 23.80 suggests a moderately powered hull for her weight. On the numbers, the calculated maximum speed is about 8.6 knots against a theoretical displacement-hull limit of 8.8 knots, and the wetted surface of about 76m2 (818 ft2) bears on that resistance. The capsize screening value of 1.82 and a motion comfort ratio of 33.7 describe a stable, easy-going hull form rather than a lively one, while an immersion rate of about 2,327 pounds per inch speaks to the weight needed to depress her waterline.
Accommodations and Tankage
Below, the Trintella 53 is laid out for a small crew or a couple with guests, with six berths in the standard plan. She is built to stay out: fresh water capacity is 1,250 liters (330 US gallons), and the fuel tank holds 798 liters (210 US gallons) to feed a diesel auxiliary. The listed inboard diesel may be equipped at 121 hp with a shaft drive, a conservative propulsion choice for a yacht of this displacement.
The Verdict
The Trintella 53 is a specialist's cruiser — a van de Stadt centerboard ketch produced in tiny numbers, engineered for long stays aboard and flexible draft rather than speed or resale liquidity. Her heavy-displacement hull, deep but retractable keel, and generous tankage mark her as a serious passagemaker for shoal-water explorers, though the scarcity of hulls means any buyer works outside a broad support network.
Pros
- Pivoting centerboard keel allows both coastal and inland cruising with marina access at reduced draft
- Six berths with 330-gallon fresh water and 210-gallon fuel capacity for extended independence
- Stable, comfortable hull metrics (capsize screening 1.82, motion comfort 33.7)
Cons
- Only a few hulls built, limiting fleet knowledge and spares commonality
- Heavy displacement and large wetted surface cap speed near 8.6 knots
- Ketch rig with long sheet runs demands careful rig management
