Evo Sport 53m
SHARP DESIGN Naval Architects and EVOLUTION YACHTS WORLDWIDE have teamed up to produce an exciting new concept for a 53 meter cockpit motoryacht with design styling and performance modeled on the traditional sportfisher platform.
The exterior design is modeled on the proportions of the traditional sportfisher with unbroken sweeping sheerline from high bow to low stern, accentuated long foredeck and swept back superstructure. The design cues call for organic soft curves with no harsh angles on forward vessel entry planes and open view vistas facing aft.
The plumb stem and enclosed swim step visually frame the sweeping hull and house lines and in addition form a full length waterline for maximization of performance within the set length envelope. The normally long slim hull form of the sportfisher style is drawn finer forward with the plumb stem making a pleasingly sharp entry. The stainless steel stem cap gives a retro look reminiscent of the early commuter yacht style which blends nicely with the organic curved art deco lines of the superstructure.
Below the waterline the hull form is a deep-vee hard chine style with a higher than normal length to beam ratio than normally seen for yachts of this size, again pointing to the desired performance characteristics desired in the design. The hull features a cutaway forefoot with narrow entry smoothly faired into a long straight run of the hull planes aft to the transom. There is a very slight tuck in the waterlines running aft from the maximum beam location and very slight buttock rise angle from the maximum depth location. The clean run aft is broken only by the tunnels port and starboard, designed to accommodate the steerable Zeus drives and incorporated trim tabs. The transom below the swimstep is angled forward athwartship from the centerline and raked forward as it extends downward to promote enhanced backing down performance and directional stability in reverse at speed.
The sportfisher theme is further carried out with the low covering boards at the cockpit sides and corners, the large multi-chamber bait tank at the end of the cockpit, the powered fighting chairs at the swimstep, full walk-around decks with unimpeded access all around to follow a fish and the three person observation bucket with clear view lines to all deck areas and around the vessel at the highest point of the yacht.
The interior design also follows contemporary sportfisher design with a few twists to compliment the size of the yacht, the level of service expected for a yacht of this class and the spaces created in the styled envelope. The top deck gives a nod to lounging in the sun with open settees and the spa comforts normally found on a yacht of this size. There is plenty of deck space for sunpads if desired.
The upper deck has the main piloting station with all vessel command and control equipment and wrap around windshield, Captain’s suite, small lounges inside and out and exterior day head convenient to the upper deck and observation bucket.
The main deck, as for most sportfishers, features the tenders forward. But with the size and style of this yacht the tenders are enclosed in their own garage allowing for better maintenance conditions and the preservation of the unbroken profile lines. Aft of the tender garage area is the large open-plan galley and food preservation and preparation area, followed by the crew
lounge and mess to port and guest day room to starboard at the head of the main companionway to the owner and guest suites below. The main access to the crew spaces is located off the crew mess on the port side. Access to the exterior main deck port and starboard is provided off the crew lounge to port and the guest day room to starboard. This arrangement is designed to separate the crew service functions with attendant noise, smells and intrusion from the guest and owner activities while still allowing easy flow of each and full access to all spaces as desired.
The main deck lounge and dining areas, aft of and separated by bulkhead from the service and day room spaces, are meant to be light and airy with oversize windows port and starboard plus full height glass wall at the aft end. Outside dining is provided by the large settee and table at the aft end of the California deck overlooking the cockpit, again in a nod to the sportfisher style of arrangement.
The below deck arrangement of spaces is designed to concentrate the noise, smells and confusion of the operating side of the yacht from the Owner and Guest accommodations. The engine room and drive components are concentrated aft with the main propulsion engines, MTU 20V4000 M93, 3900 kW, direct connected to the steerable, contra-rotating propeller Zeus drive
units. This concentrates all heat, noise and vibration sources aft, away from guest spaces. In addition, the crew accommodations spaces are located just forward of the engine room providing a nice buffer zone from the machinery noises, etc., for the Owner and Guest accommodations and in addition providing central access to service areas and the yacht in
general directly from their quarters without intrusion on guest activities. The Owner and Guest suites below deck are laid out consistent with the normal large sportfisher theme, but with larger than normal deck space and room volume. The hull structure will be all aluminum alloy with integral tanks – 68,000 litres fuel, 11,350 litres fresh water – and with superior sound dampening system incorporated. The superstructure will be carbon-fiber/composite.
Top speed is projected at 33 knots with economical cruise in the 20 knot range. Slow speed maneuvering will be by directed-jet thruster system with joy-stick control. SHARP DESIGN and EVOLUTION YACHTS WORLDWIDE are pleased to announce this joint venture and are now involved in further technical development of the project details.
