Crystal Boat 2012 Tender Boat of the Year

Not just sleek in design, the Spire Boat Crystal is powered by a Yamaha F300B outboard motor to go fast and faster. After many years of development for powerboat competitions, the experienced engineering team worked to conceive a catamaran hull that would blend a pleasure boat feeling with phenomenal speed, considering all aspects of hydrodynamics, aerodynamics, aesthetics, ergonomics, acceleration and endurance. The outcome? It feels like driving a Lotus on an empty motorway.
Crystal Boat
Crystal Boat by Marianna Holoway. Awarded 2012 Tender Boat of the Year.
The concept Design structured by the geometry of the crystal (reference to the name of the vessel). Designed a new skin – shell-which embraces the existing vessel following the contours, but also shaping the overall volume. This new skin is composed of a semi perforated structure that follows the geometry of the crystal.
These new sections of the vessel are illuminated with fiber optics so at night it appears as if hovering the upper part where we find two floodlit wings( wings with lights ).The casing leaves open the visual field in front of the passengers and to the side. The transparent elements accordingly to the intensity of sunshine, browned (special glass surfaces) to protect from the sun the luxurious interior of the vessel. We might even say that it is sun-energy for photovoltaic solar energy which gives more power to the boat.The upper casing of the boat will receive the highest number of interventions due to the hydrodynamic characteristics of the lower portion should be kept intact. With this logic a set of ribs, convex (cushions) and concave portions Biomimetic logic spread to upper housing organizing the structure at both surface (skin), and at the level functions (cab cab, front deck-pads, etc). In this way an overall structure which presents morphological interest, and includes different qualities and materials slides through a single logic sculpture.CRYSTAL… A NEW MODEL OF SPIRE BOAT DESIGNED BY MARIANNA HOLOWAY
