Friday, March 12, 2021 Ada Yacht Boat Hulls and Types Hull types and classification of boats Boats are a part of the life of sea lovers. Boats are almost a living space for sea enthusiasts and these people enjoy spending most of their time on their boats. Thanks to the technology we have reached today in boat production, boats and boat types have also increased. It is unfortunately difficult to classify the hull types of boats precisely. These can be categorized differently by different sources and people. The most accurate method used in the classification of the boat structure is undoubtedly the classification to be made considering the construction type of the boat, the hull material and the purpose of use. During the manufacturing phase, it is possible to divide the boat types into two basically according to the hull shape of the boat. The hull of the boat is designed by the designers to be "sliding in the water" or "splitting the water". Boats have to push the water level equal to their masses in order to navigate on the water surface. In other words, boats change places with the water they push. The mass in this definition is the displacement of water called Displacement. It is aimed that boats with displacement hulls repel the most water at optimum power. Sliding or in other words, Planer-based boats are boats that can slide on the water surface. Generally their engine power is high. The bottom forms of these boats are often referred to as Flat or V bottom. Examples of displacement boats include sailing yachts, gulets and many cruise ships. These boats have a water splitting hull to move through the water. Planer hull boats are generally motor yachts. These types of boats move sensually on the water. The table below is a resource that can be used for boat hull types classification. Boat Hull Types BOAT TYPES EXAMPLES ADVANTAGES DISADVANTAGES Flat Bottom Boats River Fishing Boats Suitable for shallow waters. They can be easily transported. It is suitable for calm water and lakes due to its short side heights and its carrying capacity is low. Flat V Bottom Boats Recreational fiber boats and Jet Skiies They are balanced at a certain speed. Their carrying capacity is slightly higher. They are not stable at low speeds. Deep V-Bottom Boats All boats that require speed They are very stable and durable. The risk of capsizing is low. They are heavy by design and require high engine power. Round Bottom Boats Sailboats and Canoes They can move easily on water. There is a possibility of capsizing. Multi Hull Boats Catamarans and Trimarans They are stable and stable at driving speed. Their decks are quite wide. It is not possible to maneuver in narrow waters. The best example of multi-hull boats is the Katamaman. The biggest disadvantage of these types of boats, which are very popular today, is their lack of maneuver. These types of boats have very low maneuverability. Therefore, this is a situation that affects the performance of the boat. In addition, due to their wide body, they may have problems in finding mooring places in marinas. Most of the small pleasure fishing boats are type without hull forms. One reason for this is the balance and stability to be achieved at low speed. One of the advantages of the boats is that the waves stay between the two hulls of the boat, so they are more balanced. Since they have double hulls, their hull volumes are narrow, so the interior living areas are sectioned except for the deck and the hall. They are light boats due to their hull form.
