molitva leyli Advanced High Speed SWATH Yacht - Canted Strut CS-SWATH
Developed and patented by a leading aerospace company, the Canted Strut Small Waterplane Area Twin Hull CS-SWATH, is wide hull design ideal for long range cruising at moderate speeds, while the more advanced High Speed SWATH can glide at 45-55Knots. Composed by two submerged torpedo like lower hulls of a varying cross-section connected to upper hulls (sponsons) by four canted struts which pierce the water surface. A SWATH is totally supported by buoyancy from the fully submerged torpedo like hulls. The reduced waterplane area of the struts partially decouples the ship from wave action on the sea surface, thus substantially reducing wave-induced force moments acting on the vessel and producing very very small ship motions in rough waters at most headings and speeds, which translates in an unsurpassed ride quality and seamanship.
Variable Draft High-Speed SWATH Yacht
HS-SWATH. Developed and patented by a leading European Navy scientist from BENTLEY MARINE and offered exclusively by BENTLEY MARINE, the variable draft High-Speed Small Waterplane Area Twin Hull HS-SWATH, uses a slender patented semi-planing hull that reduces wave drag, making it possible for this unique SWATH to achieve 45-60 Knots cruising speeds in very heavy seas.
4 Hull SWATH – Four Interconnected Variable Draft Torpedo Like hulls
QUADTM 4-Hull SWATH. This innovative SWATH design, is based on four interconnected variable draft torpedo like hulls, which increase hydrodynamic and seakeeping performance for greater speeds and superior comfort. Variable draft, means you can navigate in shallow waters too.
QUAD’s short hulls are able to rise above the wave “hump” much more quickly, similar to the way a ski boat pushes a large wave when it’s traveling slowly but rises above that resistance when it reaches higher speeds. Contrary to displacement yachts, which are heavy “floating tubs” too large to move beyond the hump and encounter more resistance the faster they go, thereby becoming fuel inefficient at higher speeds, the QUAD offers about twenty times better seakeeping in heavy seas with the ability to maintain full speed.
A 115ft QUAD 4 Hull SWATH, has seakeeping characteristics comparable or superior to a 350ft monohull ship.
QUAD’s exclusive Multi-Display Touch-screen Control and Maneuvering System makes it a snap! The computer controls an automatic Fin / Ballast Motion System and has Alarm and Monitoring capabilities.
SWATH Monohull with Outriggers
The ultimate technology for large Fast Container Ships or even Aircraft Carriers, with far superior seakeeping than monohulls, better fuel consumption and increased deck space. BENTLEY MARINE Team of Naval architects and engineers are the world leaders in this technology are are ready to suit your particular commercial or military needs.
BENTLEY MARINE SWATH Monohull with Outriggers provide far better seakeeping and speed than the recently launched English military ship TRITON which uses a conventional monohull with outriggers.
Unique Advantages of SC-SWATH and QUAD Hulls
Seasickness Elimination Design
The SC-SWATH and QUAD do not bob up and down like a cork on top of the waves as conventional monohulls and catamarans do. Its submerged hull rides like a submarine below the waves, while the waves passes harmless through the surface piercing struts, giving these type of vessels motion characteristics of ships three times its length and up to twenty times its displacement.
More Deck Space Yacht
The SC-SWATH and QUAD wider beam-to-length ratio provides much more deck space then comparable displacement monohulls, meaning more useful space along the ship.
Ability to maintain Speed and Direction in Rough Waters
Conventional ships must dramatically reduce speed in rough sea conditions to avoid slamming damage from waves and to avoid seasickness of passengers onboard. Like hydrofoils, the SC-SWATH and QUAD can maintain up to 90% of its speed under sea state 4, conventional monohulls and catamarans only up to half of it.
Excellent Low Speed Maneuverability Yacht
The SC-SWATH and QUAD wide separation of its propellers enables them to make a complete circle within its length at zero forward speed. source Bentley Marine; http://bentley-marine.com/
