This innovative concept seeks to address a critical limitation in ship design, specifically the relationship between speed and hull length governed by the Froude number. Typically, as a monohull accelerates, it generates a bow wave with a wavelength proportional to its speed. When the wavelength approaches the ship’s length, the vessel encounters significant wave-making resistance, which traditionally necessitates a longer hull to achieve higher speeds. The proposed system targets this limitation by manipulating the ship-generated wave system to reduce drag and enhance efficiency.\par

Concept Proposal: Vertical Plate Outriggers for Wave Management

Imagine a monohull ship equipped with vertical plate outriggers designed to capture the bow wave, channel its energy along the hull, and direct it toward the stern to cancel the wave there. This novel concept addresses the speed limitations imposed by the ship's length.

Key Features

  • Wave-Making Resistance as the Target:
    • The design tackles the bow wave generated by the ship's motion. As the ship speeds up, the wavelength of the bow wave increases, eventually matching the hull length and increasing resistance.
    • The vertical plate outriggers intercept and channel this wave energy before it fully develops, mitigating its impact on the hull's speed.
  • Wave Redirection for Cancellation:
    • The vertical plates capture the bow wave as it forms, redirecting the energy along the hull toward the stern.
    • This redirected wave energy either dissipates or interferes constructively with the stern wave to minimize resistance.
  • Impact on Ship Length-Speed Relationship:
    • The system disrupts the traditional hull-length speed limitation, allowing shorter ships to achieve higher speeds without requiring a longer hull.
    • This leads to potential reductions in material costs, displacement, and overall drag.

Ocean Waves: Irrelevant to This Design

  • This proposal focuses exclusively on internally generated wave resistance caused by the ship's motion.
  • It does not address ocean waves (e.g., swells or sea state), which primarily affect stability rather than hull-generated wave systems.

  • Fuel Efficiency:
    • Lower wave resistance translates to reduced energy consumption.
  • Stability Enhancements:
    • The vertical plates may also function as stabilizers, reducing roll and improving handling.

Key Challenges

  • Hydrodynamic Efficiency:
    • Placement and angle of the vertical plates must be optimized to ensure effective wave capture and redirection.
  • Structural Integrity:
    • Outriggers must be strong enough to handle wave forces while maintaining ship balance.
  • Timing of Wave Cancellation:
    • Precise control is needed to align redirected wave energy with the stern wave for effective cancellation.
