Some would argue that this view is contradicted by trends in classes such as the F18 and A-Class catamarans, and the International Moth. The F18 and A-Class cats have both seen a trend to wider, flatter hulls in recent years. However, this occurred prior to the successful use of efficient lifting foils. I would not be surprised if, once full foiling becomes more commonplace in these classes, a trend back to more conventional displacement-type hulls occurs.
