There are three main hull types: displacement, semi-displacement, and planing. In brief, a displacement yacht offers high comfort, good volumes and a longer range; a semi-displacement yacht is a crossover between performance and comfort; and a fast-planing yacht suits those who like to travel at speed and who don’t require a long range. You can also choose the number of hulls, with options including monohulls and multihulls such as catamarans and trimarans.
