Article: Trim Optimization – Using NavCad for Prediction Confidence
There are cheaper, less time consuming alternatives to CFD surrogate models, writes HydroComp’s Don MacPherson. This article has been reprinted with permission from the October 2020 issue of The Naval Architect. One tool in an operator’s hunt for fuel reduction...Performance Prediction for Sailboats Under Auxiliary Power
While the primary objective of most sailing vessel designs is performance under sail, auxiliary propulsion is also an important consideration. Often, the heaviest non-structural components on a sailing vessel are the engine and its fuel. Since weight reduction is key...Towpull: System Analysis and Component Sizing
Tugs, trawlers, and other workboats require the ability to generate thrust for more than their own transit. They need supplemental thrust – known as “towpull” – to pull nets or push other boats. More than just “bollard pull”, towpull requires a properly functioning...
Article: UV Tail Shape and Vehicle-Propulsor Performance
Successful underwater vehicle (UV) performance is all about a properly functioning system. The components of a UV’s Vehicle-Propulsor-Drive system are not individual performers. They must be in harmony. Often overlooked during system design is the relationship between...
