As a result of a federally funded research project, Kitsap Transit, underwent a study to not only implement a beach monitoring system for erosion, but also brought on All American Marine and Teknicraft to research a low wake wash vessel design.
With the community and mission in mind, a wake propagation model was developed to predict vessel wake parameters (i.e. height, period, direction, and phase) at the shoreline along the proposed ferry route. This model was used to evaluate the potential effects of alternative fast ferry operations on shoreline erosion and sediment transport.
The ultimate goal was to evaluate potential shoreline protection solutions for areas where the impact cannot be minimized. Using a Computational Fluid Dynamic (CFD) Modeling Automated Systems-Based Design, tank testing, and a vessel optimization study featuring 3 different hull shapes, 3 different hydrofoil profiles, and 9 new vessels, Teknicraft and All American Marine designed and built the Rich Passage. It is the lowest wake wash vessel in its class, setting a new standard in hull design. A huge win for our operators working in sensitive areas, and applicable to many vessel types and industries where erosion and environmental impact need to be considered.
