Design considerations for a cruising yacht include seaworthiness, performance, sea kindliness, and cost of construction, as follows:<ref name="RYA" />

* ''Seaworthiness'' addresses the integrity of the vessel and its ability to stay afloat and shelter its crew in the conditions encountered.
* ''Performance'' hinges on a number of factors, including the waterline length (longer means faster), drag in the water (narrower hull with smooth appendages), hull shape, and sail shape and area.
* ''Sea kindliness'' is an indicator of steering ease, directional stability and quelling of motion induced by wind and waves.

Multihulls offer tradeoffs as cruising sailboats, compared with [[monohull]]s. They may be catamarans or trimarans. They rely on form stability—having separate hulls far apart—for their resistance to capsize.<ref name="RYA" /> Their advantages include greater: stability, speed, (for catamarans) living space, and shallower draft. Their drawbacks include: greater expenses, greater [[windage]], more difficult tacking under sail, less load capacity, and more maneuvering room required because of their broad beam. They come with a variety of sleeping accommodations and (for catamarans) bridge-deck configurations.<ref>{{Cite book|last=Tarjan, Gregor.|title=Catamarans : the complete guide for cruising sailors|date=2008|publisher=International Marine|isbn=978-0-07-159622-0|location=Camden, Me.|oclc=233534126}}</ref>
