Boats that are designed for sports competitions must be able to withstand increased loads. That is why high-strength and wear-resistant materials are usually used in their manufacture. The hulls are made of one-piece, and the control system is made as responsive as possible even to a small turn of the steering wheel. The latter factor allows you to perform complex turns at high speeds, which are akin to figure skating. If we return to the material from which the craft is made, then usually it is an aluminum alloy.
Open-type boats are distinguished by high-speed qualities and outboard power plants. Their advantage is not only excellent driving performance, but also excellent cross-country ability. Even with a long journey, they will maintain a comfortable feeling. Stationary engines are more commonly found on larger ships with deck superstructures. This is a completely different category of water transport. Nevertheless, a trip on a sports boat is a spectacle not only pleasant, but also spectacular. Therefore, in the video from the channel "In Search of Facts" you can see a whole selection of some of the fastest sports boats.
