M-Hull Origins

• M-Hull was developed as a solution to a problem
  in Venice ItalyWave damage.
• Singularly focused design solutionLow wake.
• Serendipitous discovery.

6
M-Hull High Speed Validation

• Convert captured wave energy into a useful form

Higher speeds Improved stability Smoother
ride quality
Reduced signature Increased payload
fraction Elimination of hull speed limit
7
M-Hull Geometry

• 3 distinct elements
• Central displacement
• section
• Planing tunnels
• Skirts

8
Central Displacement Section

• Static support
• Displacement lift
• Fine, deep bow
• Broad, shallow exit

• Efficient displacement lift
• Does not inhibit high speed performance

9
Planing Tunnels

• Hydrodynamic lift
• Aerodynamic lift
• Independent planing
• surfaces

• Planing tunnel lift
• No hull speed limit
• Positive angle of attack
• Small trim change

10
Skirts

• Contains Bow Wave
• Natural surface effect
• Loitering stability
• Dynamic stability

• High speed aeroplaning
• Poor mans hovercraft
• Enhanced Lift/Drag ratio
• Safe surface-effect

11
M-Hull Dynamics

• Recaptures bow wave energy
• Aeration of water
• Reduce viscous drag
• Use wave energy

12
Reduced Signature

• Elimination of bow wave
• Reduced Kelvin ship wave
• Aeration passively dampens visible and acoustic
  signature

13
Smooth Ride Quality

• Hull shape reduces excitation response
• Fine entry of bows
• High volume aft sections
• Self adjusting wave damping
• Pneumatic cushion

14
Stability

• High speed dynamics
• Water entrainment at loitering speeds
• No heel turns

15
The Art of the Possible

• Demonstrated enormous potential on small single
  M-hulls
• Next step was to evaluate the scalability of the
  design
• If possible, it could lead to a new ship design
  operation paradigm

34
Conclusion

• Evaluating the scalability of multi M-hull
  concept.
• Developing teaming arrangements for rapid
  knowledge transfer.
• Demonstrating new construction techniques with
  advance composites using non standard builders.
• Solving the challenges of military homeland
  defense operations in the Littoral and Riverine
• Accelerating the learning curve by avoiding
  temporization of new ideas.
