Solution Overview
Problem
Current high-speed ocean-going ships face challenges in achieving and maintaining a planing state efficiently, especially when fully loaded, due to insufficient cruise power and drag-related issues, limiting their speed and operational efficiency.
Innovation Solution
The implementation of a boost phase assist structure and load shift mechanism, including a retractable lateral wing structure with auxiliary power, to assist vessels in achieving and maintaining a planing state, which can be deployed during initial acceleration and stowed during cruise to minimize drag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a vessel uses cruise power alone to achieve planing state, then the structure remains simple, but the vessel cannot achieve planing state when fully loaded due to insufficient power
Solution Approach 1:
The power system is segmented into two distinct components: a cruise power source for normal operation and a separate boost power source for achieving planing state. This segmentation allows each component to be optimized for its specific function, with the boost power providing the additional thrust needed when fully loaded without requiring the entire power system to be oversized for peak performance alone.
Solution Approach 2:
The power system transitions dynamically between cruise mode and boost mode depending on operational requirements. The boost power is activated only when needed to achieve planing state, allowing the vessel to adapt its power output dynamically rather than maintaining a fixed, overly complex power system configuration.
2Productivity
If a vessel operates at high speed with planing state, then transit time is reduced and productivity increases, but drag increases and requires more power
Solution Approach 1:
The boost power is used in advance to accelerate the vessel to planing state before the main cruise journey begins. By achieving the planing state preliminarily using the boost power, the vessel can then maintain high speed during cruise using only the cruise power, reducing continuous energy loss from drag.
Solution Approach 2:
The boost power is applied periodically only during the initial acceleration phase to achieve planing state, rather than continuously. This periodic activation allows the vessel to benefit from high-speed planing operation during cruise while minimizing the energy loss associated with continuous high-power output and drag.
3Quantity of substance
If a vessel uses larger ships for reduced cargo ton-mile costs, then cargo capacity increases, but the number of ocean crossings per year decreases due to time-consuming port visits
Solution Approach 1:
The vessel dynamically adjusts its operational mode by using the boost power to achieve planing state, enabling larger ships to travel at high speeds across oceans. This dynamic power adjustment allows cargo vessels to complete crossings rapidly without frequent port stops, reducing the time loss associated with large ship operations.

AI summary
A high speed ship configuration for achieving a plane state efficiently, with threshold power available in fully loaded cargo ship. The system may include a boost phase assist structure to assist in the achievement of a plane state. The boost assist may be external or internal to the ship. The boost assist may provide power and/or lift assist. One embodiment may include a launch rail. In one embodiment, the configuration includes a retractable lateral wing structure disposed toward the stern of the vessel and containing auxiliary power providing thrust for the vessel. The wing structure is deployed during an initial boost phase acceleration and may be stowed in the vessel once the vessel achieves full plane operation. In one embodiment, the boost power structure may include propeller drive, paddle drive, or waterjet drive. The boost power structure may provide buoyancy and/or hydrodynamic trim to assist in achieving plane state operation.
