This report documents the generation of several seaway load prediction algorithms for catamarans, trimarans, and surface effect ships based on available model and full-scale test data. These algorithms are intended for use as quick predictions of seaway loads during ship feasibility and concept design studies. Froude scaling laws are used for geometrically different ships for each ship and load type using first principles and empirically derived studies. Simple seaway load prediction algorithms are then developed and expressed as functions of ship displacement and various key ship particulars. These global load algorithms are quickly computed, making them suitable for preliminary or concept design studies. In some cases, algorithms were developed from a minimum amount of data, and it is anticipated that, as more data is gathered in the future, these algorithms will be further refined. As the ship design progresses and is refined, more accurate but time consuming computational analyses and model tests are appropriate. For completeness, previously developed algorithms for small waterplane area twin hull ships (SWATH) are included in the appendix.
