More about the unique advantages of Hydrofoil hulls and A-foil equipped BENTLEY Marine vessels:

Seakeeping of Hydrofoils:
   
    Some of the principle advantages of hydrofoil ships, over all other monohull or alternative ship types are:
1) The ability of a ship, which is small by conventional ship standards, to operate effectively in nearly all sea environments, and
2) An improved ratio of power to displacement in the 30 to 50 knot speed range permitting economical operation at these higher speeds. The submerged-foil ship can maintain its speed and maneuverability in heavy seas while simultaneously providing a comfortable working environment for the crew.
   
    The ship's automatic control system (ACS) provides continuous dynamic control of the ship during takeoff, landing, and all foilborne operation. In addition to providing ship roll and pitch stability, the ACS controls the hull height above the water surface, provides the proper amount of banking in turns and all but eliminates ship motions caused by the orbital particle motion of waves.

Maneuvering of Hydrofoils:

    Besides the significant speed advantage, hydrofoils are more maneuverable and provide a more stable platform than conventional ships. Foilborne turns are accomplished in a banked (coordinated) fashion. This causes the centrifugal force required in turns to be provided predominantly by the reliable lift capability of the submerged foils rather than by the unpredictable side forces from the struts. Turn coordination enhances crew comfort during high-rate turns because the accelerations due to turning are felt primarily as slightly greater vertical forces rather than lateral forces. For example, a 0.4g turn is felt as only 0.08g vertical acceleration increase while the lateral acceleration is zero. Therefore, hydrofoil ships have design turn rates of 6 to 12 degrees per second, two to four times those of conventional ships, and they can maintain these rates in both calm and rough seas.  The exceptional stability of the hydrofoil ship makes it a superior platform choice for today's ferry operators.

  Vari-Draft^TM Variable Draft Ice-Class SWATH Ship Technology

       
BENTLEY MARINE Vari-Draft Ships can drive right into an unprepared  beach in landing craft mode to load and unload cargo and/or passengers

Next Gen Canted Strut CS-SWATH Technology

    Developed and patented by a leading aerospace scientist, 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 Ship is totally supported by the 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.

    An advanced touch screen automatic motion-control system provides a the smooth ride.

Next Gen High-Speed Autonomous HS-SWATH Ferry :

80' Fast Ferry Vectra with variable draft HS-SWATH hull

    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.

  QUAD^TM 4-Hull High-Speed 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.

More about the unique advantages of HS/CS-SWATH and QUAD hulls:

Seasickness Elimination: The HS/CS-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: The HS/CS-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 HS/CS-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: The HS/SC-SWATH and QUAD wide separation of its propellers enables them to make a complete circle within its length at zero forward speed.

Next Gen Air Cavity Technology for 35% less hydrodynamic drag

Air cavity Hull Laboratory Model Testing

    Dynamically supported Air Cavity hulls provide greater speed per horsepower in planning monohulls and catamarans.  BENTLEY Marine has several designs of monohulls and catamarans with this fuel efficient technology.

    The main feature of ACC is the configuration of the bottom of the hull that has a delta shaped hollow composed of board flanks and stern profiling platform.   In the delta shaped hull hollow there are slots through which air is injected and air cavity is formed  when ship is moving,  isolating part of the bottom surface of ACC from the water and decreasing friction resistance in about 30%.

    ACC hulls have bottom sections before and behind the cavity that are in stationary contact with water. These sections not only protect air in the cavity from leaking, but also render forming action on cavity surface.  The volume of air cavity in an ACC is much less than that of the cushion in a hovercraft and corresponds only to 2-3% from the power of main ship engines.

    The simpler construction of ACC provides great advantages in comparison with other high speed ships with dynamic principles of support.

Our current commercial, pleasure and military designs range from 20 tons to over 1000 tons. The giant 1000 Ton version can achieve speeds over 120 knots and operate in Sea State 5 conditions, becoming the Littoral Combatant, passenger Ferry and cargo ship of the future. Able to carry heavy helicopters at high speeds, the WPT will soon prove to be a superior and attractive Military Ship. It's Stealthy superstructure with concealed weaponry capability will outperform even the most advanced military monohulls and catamarans in the battle field. The extremely flexible modular design also makes the WPT an ideal passenger & cargo platform for offshore operators.
