Data From Trials
Seakeeping, safety, cost to build and maintain, fuel economy, and ability to meet schedule in a variety of conditions must all be considered when applying a particular vessel design for use as a fast ferry for any particular route.
The model tests performed for the 1/4 scale MM56CX test craft, among the largest test craft ever built for this purpose, have demonstrated the abilities of the platform to meet those needs. Motions of the vessel in scale conditions equal to significant wave heights ( H1/3) of 3.0M have proven it's capabilities to the test crew- allow us to prove it to you.
Below are the results for the original foil system, presented as 1/3rd Octave vertical accelerations compared to the O'Hanlon and McCauley 'Motion Sickness Incidence' curves and the ISO 'Fatigue Decreased Proficiency' curves typically used for assessing the effect of exposure to these motions on humans. You will note that the vessel motions for the MM56CX 56 M full scale craft are centered in a region where people are less sensitive to the motion, unlike displacement catamarans and monohulls.
