<p>Monohull boats are vessels with just one hull, as the name itself suggests. They can be monohull <a href="https://theboatdb.com/boats/type/sail">sailboats</a> or <a href="https://theboatdb.com/boats/type/power">powerboats</a>, which means they can be powered by an engine or by the wind. In addition, monohull boats can have a high level of luxury on board and can therefore be referred to as monohull yachts. At TheBoatDB you can look into monohull boats and explore their features. In addition, you can filter your search through monohull sailboat manufacturers and explore all models available on our site. Compare all models on our website from the comfort of your home.</p>
