 The increasing popularity of catamaran since the 1960s is down to the added space, speed, shallow draft, and lack of heeling underway.The stability of a multihull makes sailing much less tiring for the crew, and is particularly suitable for families.Having no need for ballast for stability, multihulls are much lighter than monohull sailboats; but a multihull's fine hull sections mean that one must take care not to overload the vessel.
