Cantieri del Golfo - Italcraft
SARIMA

Sarima

The names Mini and Beetle remind car lovers of automobiles that marked an epoch. Actually, they were a "must" for several generations and were so successful that millions of units were produced over a long period of time. Technically and esthetically renewed, both cars are now produced again for the joy of nostalgic car fans. The same thing, yet in smaller proportions, is happening in the shipbuilding industry with the Sarima. As a matter of fact, the Sarima has been one of the most widely sold boats ever, with more than 700 units produced over more than thirty years. Her success can be hardly repeated in a world where the highest number of units produced, especially in the case of larger boats, does not exceed a few dozens. Managers at Italcraft, of the Cantieri Navali del Golfo group, believe that, notwithstanding her successful past, the new Sarima will easily find a place in the yachting world panorama.

The hull was successfully tested in the ship model test basin and at sea by the Italian Revenue Service control guard, the Carabinieri and other coast guards that use her daily in the most different conditions. Because the boat is produced on a large scale, costs are reduced and the Sarima has a good quality/price ratio. She is a very comfortable open motor boat with excellent performance under way, good speed and a good helm control. The Sarima may be fitted with an inboard engine and Arneson Drive.

CONSTRUCTION CHARACTERISTICS

Hull: V-hull with chine streamlined up forward and raked stem. The two longitudinal steps on both sides end amidships, where the deadrise angle becomes considerably smaller. The hull was model tested in the INSEAN ship model test basin of Rome. The stratification process of the hull and of the deck is carried out in an air-conditioned space, in accordance with the quality standards of the yard, ISO 9001 certified
Hull construction material: fiberglass with Kevlar reinforcing supports
Deck materials and characteristics: PVC sandwich fiberglass
Bow area: PVC sandwich with anti-slipping deck. The forward deck may be used for sunbathing and eventually, on request, a surrounding guardrail for protection may be fitted. Fair accessibility
Cockpit arrangements and fittings: the helm station is to starboard with a settee for two. The dashboard includes all instruments for engine control and optional instruments may be fitted on request, such as electronic chart plotter, hi-fi and VHF. There are no flap indicators. The switches of lights, horn and windlass are adequately positioned. The dashboard is on portside and part of it may be used as outer chart table. In addition, the cockpit includes an aft settee to port. Aft of the settee, over the engine room port, there is an ample sunning area with cushioning
Characteristics of the aft platform: the aft platform is in fiberglass with a total area of 3'7"x9'4". Access from the cockpit is by way of a stainless steel ladder. The platform is fitted with a cradle for the tender, the swimming ladder - concealed when not in use - and freshwater shower
Superstructures and windows materials: window frames are in AISI 316 stainless steel and windows are in Plexiglas.

INTERIORS

Layout and characteristics: interiors have a classical layout: the master stateroom is forward, the galley is amidships opposite the convertible dinette. The aft cabin is almost along the centerline and it is fitted with a double bed. There is one bathroom with double access, from the master stateroom and from the dinette. All cabins are well ventilated, with good lighting
6 portholes, 1 forward hatch and halogen spotlights.
Galley: two-burner range and stainless steel sink (both are concealed when not in use), anti-scratching worktop, two drawers, two-shutter hanging cabinet and cabinet under the sink.

IMPRESSIONS

SEA AND WEATHER CONDITIONS DURING BOAT TESTING
Wind: 5-6 knots
Sea: long swells
Notes: sea trials were carried out with half filled fuel tank, fully filled freshwater tank, standard fittings and 4 passengers

PERFORMANCE
Time needed to reach planing speed: 6 seconds
Minimum planing speed at 2,000 rpm's: 15.2 knots
Cruising speed at 3,400 rpm's: 30.7 knots
Maximum speed at 3,900 rpm's: 38.5 knots with 460 hp engine

EVALUATION OF PERFORMANCE

Seakeeping ability, turning and behavior on waves: the weather and sea conditions were good so it was not possible to test the capabilities of the boat. Nevertheless, the Oyster 34 showed excellent seakeeping ability and behavior on waves (in the wake of other motor yachts). The most remarkable characteristic is the short time needed to reach planing speed with the engines in low gear. This means that, even though the boat sails fast, fuel consumption is relatively low
Wheel and flap response: wheel response is immediate and efficient at any speed. The boat is very sensitive to trim changes made with flaps, but the sea, weather and loading conditions during sea trials were not sufficient to fully test this feature. Maximum speed was reached with flaps at rest and trim in +2 position
Visibility in different weather conditions: excellent even when sitting. The windscreen offers excellent protection. Docking maneuverability: the boat is extremely maneuverable even in small areas because of the two stern drives.

EVALUATION OF COMFORT AND FUNCTIONALITY

Deck: the deck has a clean and classical line with a balanced division of space between the cockpit and the forward area. No guardrails were fitted forward for esthetical reasons and for greater space availability, even if they are commonly found on this type of boat. Stainless steel guardrails may be fitted on request. The cockpit is beautiful, very well arranged and ample
Interiors: notwithstanding the size of the boat, interiors are ample and cozy. The aft cabin has lower headroom but it is still very comfortable and spacious. Interior décor reflects the Italian style, especially in the furnishing, accessories, upholstery and their chromatic combination. Nevertheless, one must consider that the tested boat is a prototype and finishing details may be changed and improved. The dinette is very cozy with a folding table of adequate size. Lockers, cabinets, hanging closets for personal equipment and for storing food and supplies are abundant.
Passengers' comfort: excellent. During sea trials, with the boat at full speed, (approx. 40 knots) and engines at full throttle, passengers could easily chat in the cockpit without rising the tone of their voices, thanks to the perfect noise insulation of the engine room and the protection of the windscreen. The windscreen offers excellent protection even to passengers sunbathing on the aft sunning area
Helm station: fair. The steering position could be improved if the inclination of the steering wheel were adjustable
Galley: of adequate size and fully fitted. Lockers and cabinets for storing food and dishes are abundant
Bathroom: not very spacious but very well arranged
Engine room: access to the engine room is by way of the electrically operated hatch in the aft sunning area. Everything is at hand and may be easily checked
Electrical switchboard and plants: the switchboard, fitted in the aft cabin, with switches and voltage indicators seems adequate and of good quality.
