摘要

The paper represents a promising hydrofoil design. However in my opinion there is one important flaw that needs to be addressed. Without some modification, the craft as designed will have problems with a destructive yaw / outside-roll couple.It is my observation through model testing that when this craft yaws or turns to port it will roll to the outside, i.e., starboard. This is unlike most conventional stable designs where a yaw initiating a turn or side-slip to port will induce a rolling moment to the port resulting in a balanced turn. This is commonly called "rolling into the turn", and that is normal in boats, hydrofoils, and aircraft. Rolling to the outside is unstable.To prove this assertion, a short series of mathematical calculations were performed to estimate and quantify the problem - see Table Ia and Ib.
