The Hull Fineness Ratio known as the hulls beam-to-length ratio is an interesting number. While it works well in heavy seas the drawbacks include reduced interior volume forward and a very wet ride because the waves come up and over the bow as a matter of course. In the daysailing sizes catamarans are faster than trimarans owing to their ability to fly the windward hull and sail on one hull at a modest angle of heel.
