MMC personnel can assist you in constructing accurate models for tank testing or free-running experiments.

Maine Marine Composites has established relationships with most of the hydrodynamics testing facilities (towing tanks) in North America, and can manage your entire testing program
We will work with you to determine the model loading conditions, operating speeds and wave conditions. Tank testing can be expensive, and proper planning is required.
We can help you with any or all of this -- we've done it many times and we've collected a lot of tankery tricks over the years.

Some tests have to be run in large basins or even lakes. It is difficult to perform maneuvering tests in a long, slender tank so engineers create radio controlled models and test them in sheltered lakes or basins.
MMC can design and construct radio-controlled models, including everything from the hull-form to the data telemetry system.
Tank and model testing can be expensive. An alternative to tank testing is to simulate your design with a computer model, to perform virtual tank testing. Maine Marine Composites has a number of computer analysis tools that can meet some of your analysis needs at a fraction of the cost of a full-blown model testing program.

Developed by MMC staff, the POWERSEA program predicts the motion of a planing boat in calm water, regular or irregular seas. We specify the forward velocity or thrust and the shape of the waves or wave spectrum, and POWERSEA calculates the hull’s motion including surge, heave and pitch displacements, velocities and accelerations.
POWERSEA is used to predict time dependent effects such as porpoising, deck wetting and boat accelerations:
