8.5.2.4.Watersport Boats or skiiboats
These are high-powered Go-Fast boats (specialized towboats in fact) is designed for activities where a participant is towed behind the boat such as waterskiing and parasailing.

• Variations on the ubiqutous water-ski include wakeboards, water-skiing, kneeboarding, inflatable towables, and wake surfing. To some degree, the nature of these boating activities has an impact on boat design. Waterski boats are intended to hold a precise course at an accurate speed with a flat wake for slalom skiing runs. Wakeboard boats run at slower speeds, and have various methods including ballast and negative lift foils to force the stern in the water, thereby creating a large and "jumpable" wake.
• Saltwater fishing boats vary widely in length and are once again specialized for various species of fish. Flats boats, for example, are used in protected, shallow waters, and have shallow draft. Sportfishing boats range from 25' to 80' or more, and can be powered by large outboard engines or inboard diesels. Fishing boats in colder climates may have more space dedicated to cuddy cabins and wheelhouses, while boats in warmer climates are likely to be entirely open.
• Cruising boats applies to both power and sailboats, and refers to trips from local weekend passages to lengthy voyages, and is a lifestyle. While faster "express cruisers" can be used for multiple day trips, long voyages generally require a slower displacement boat (trawler) with diesel power and greater stability and efficiency. Cruising sailboats range from 20' to 70' and more, and have easily managed sailplans to allow relatively small crews to sail them long distances. Some cruising sailboats will have two masts (ketch, yawl, or schooner rigs) to further reduce the size of individual sails and make it possible for a couple to handle larger boats. Diesel- powered Narrowboats are a very popular mode of travel (and accommodation) on the inland waterways.
