When predicting a ship's resistance, what technique involves building a small model and pulling it through water in a specialized tank to measure forces?

The technique involving building a small model and pulling it through water in a specialized tank to measure forces for predicting a ship's resistance is known as towing tank testing or ship model resistance testing. In this process, a ship model, which is a precise, scaled-down replica of the actual ship's hull, is constructed. This model is then moved through a controlled body of water contained within a long, narrow facility called a towing tank. A specialized apparatus known as a towing carriage moves along rai....
