After having consolidated its position on the market by expanding its traditional main product - boats with outboards - Sessa Marine decided to produce larger cabin cruisers as well. Last year, when the flagship Oyster 36 was presented, Sessa Marine was enthusiastically acclaimed, even more than expected. In fact, the production manager Mr. Massimo Radice, told us the number of units produced had exceeded by 30% the estimated outlook of the previous year.

These numbers explain why the yard thought of strategically launching, on the wake of the 36, a new important cabin cruiser, the Oyster 34, a smaller version of the flagship. Notwithstanding the small size, this new fast commuter is an ambitious boat with a strong personality, offering original open spaces on deck and comfortable interiors with top quality materials. The newborn Oyster 34 is the result of the experience gained in the construction of this type of boats. The Oyster 34 was born from the cooperation of the yard's technical design department with Styleproject - a pool of designers, coming from the automobile sector, who have been working in boat design for years.

The result does not go unnoticed: the boat has a beautiful outside line and top quality interior finishing. At the helm, the Oyster 34 gives an excellent impression: the top speed exceeds 36 knots with two 230hp-Volvo Penta diesel stern drives, seakeeping ability is excellent and corresponds to the design spirit of the boat.

Wind: none

Time needed to reach planing speed: 4.7 seconds
Maximum speed at 3,800 rpm's: 36.5 knots
Cruising speed at 3,000 rpm's: 25 knots


Seakeeping ability: even if the lake conditions were calm and the exceptional qualities of the hull could not be fully tested, we steered the boat in the wake of a local ferryboat, at maximum speed and at cruising speed, and the Oyster 34 was smooth on the water and had an excellent trim
Wheel and flap response: response to the wheel is quick and adequate. Most probably, performance is improved when the yacht is powered by the 500-hp Mercruiser engines. Flaps are sensitive and adequate
Helm station: the pilot seat is comfortable and very well protected against the wind; instruments are easy to read and adequately positioned; the steering wheel is of high quality and throttle controls are suitably positioned
Docking maneuverability: excellent in any conditions.


Deck: ideal solutions designed for extra comfort both in the cockpit as well as forward. The forward sunning area may be easily reached through the central passage across the windshield. The superb finishing and design of the cockpit is the result of the acquired experience of the yard and of its willingness to satisfy at best its clients. The outside sink and icebox are very useful. Interiors: the finishing is excellent. Critics might dislike the American-style open space in a boat with Italian quality details. The dinette is comfortable and very well arranged, with an oval adjustable table. The galley is well fitted but discreet. Choice of a double bed or twin beds (with optional central flooring) in the aft cabin is highly appreciated. Upholstery and lining material is of the best quality. Lacquer work is worthy of the tradition of the Lesmo-based yard
Helm station: the helm station is very well protected. The three-paneled dashboard is discreet yet adequately fitted. The pilot seat may be adjusted.
