Movable Hull Panels for Surfable Wake Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine vessels lack effective devices for modifying their wake, which is essential for creating a surfable wake for wake surfing and optimizing vessel performance.
Innovation Solution
The implementation of movable panels coupled to the sides of the marine vessel's hull, which can be stowed or deployed to modify the wake by redirecting water flow laterally and downwardly, thereby creating a surfable wake and enhancing vessel performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panels are deployed to modify the wake, then wake surfability is improved, but device complexity increases
Solution Approach 1:
The wake modification system is divided into multiple independent panels (first panel and second panel) that can be independently deployed or stowed. Each panel operates separately to modify water flow on its respective side of the hull, allowing granular control over wake characteristics while maintaining system simplicity through modular design.
Solution Approach 2:
The panels are designed to be movable between deployed and stowed positions, transforming from a static hull structure to a dynamic system. This mobility allows the wake modification capability to be activated only when needed, providing adaptability without permanently increasing device complexity.
2Object-generated harmful factors
If panels are moved laterally outwardly to modify wake, then water flow redirection effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The panels are positioned and configured to utilize the natural hydrodynamic forces of water flow to drive their lateral movement outwardly when deployed. The water pressure differential created by the hull movement automatically assists in positioning the panels, reducing the need for complex active control mechanisms and simplifying operation.
3Productivity
If panels are deployed to create surfable wake, then productivity is improved, but loss of energy increases
Solution Approach 1:
The panels are deployed only during specific periods when wake surfing activity is desired, rather than remaining continuously deployed. This periodic activation allows the system to create the surfable wake when needed while minimizing energy loss during periods when wake modification is not required, optimizing the balance between productivity and energy efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively modifies the wake of the marine vessel, creating a surfable wake when needed and optimizing vessel performance by redirecting water flow and minimizing drag.
Implementation Method 1
The panel moves laterally outwardly away from the one of the sides of the hull when moving toward the deployed position. Moving the panel from the stowed position to the deployed position causes the panel to modify the wake of the marine vessel.

AI summary
A device for modifying a wake of a marine vessel having a hull. The hull extends between a bow and a transom in a longitudinal direction and between sides in a lateral direction perpendicular to the longitudinal direction. The sides each extend between a top and a bottom in a vertical direction that is perpendicular to the longitudinal direction and to the lateral direction. A panel is movably coupled to one of the sides of the hull and movable into and between a stowed position and a deployed position. In the stowed position, the panel extends along the one of the sides of the hull. The panel moves laterally outwardly away from the one of the sides of the hull when moving toward the deployed position. Moving the panel from the stowed position to the deployed position causes the panel to modify the wake of the marine vessel.
