HYSWAS Hydrofoil Small Waterplane Area Ship is a hydrofoil craft that receives typically 70% of its lift from a single buoyant pod located below a hull that at rest supports the other 30% of total weight. The pod or “lower hull” has its lift augmented by fore and aft hydrofoils. The lower hull is connected to the upper hull by a rigid strut. The HYSWAS is stable at rest because of the hydrostatic characteristics of the upper hull. Underway the foils generate lift that increases with speed, and raises the upper hull out of water. Dynamic stability is achieved by Active Flight Control System that regulates roll, pitch, and flying height. The result is stable passage through significant waves and in some cases, contour flying over ocean swells. Furthermore, Marks tells us the history of this company and their cutting edge roll played in the development of the HYSWAS concept. He also describes the parallel growth of the International Hydrofoil Society and its past and long term president John Meyer.
All of you guys are doing great work look forward to seeing what you do in the future
HYSWAS has a great deal of potential, IMO. The design shown in this video is only one possible design out of many others.
Catalina doesn't have deep enough places for that deep Catalina Express boat. The Isthmus is less than 20 feet, maybe even less, at low tide.
Perhaps there could be hydraulic struts between the SWATH hulls and the main hull. That way seasickness could be totally eliminated.
Amazing staily
Thanks !
Couldn't you engineer the lower hull to raise up and down ? Have it raised when heading for a dock or shallow water. Then lower for optimum deep water travel ? I know some sail boats have a retractable keel . Kind of the same thought. Have it lower hydraulically , then some type of mechanically actuated lock.
that would both add alot of weight and engineering costs, but i had the same idea.
Is there a way to access this study? I am very interested in this project for a development of a hydrofoil Katamaran yacht.
Although so many aspects of this design are fascinating, I can't help but think of how many whales would get rammed to death by it.
Sonar on the front of the submerged torpedo hull?
Haulover inlet beware you have seen your match
Astonishingly poor design choice @3:20 - that underwater fuselage operates at an Re of about 115,000,000 when at full speed, generating *stupendous* amounts of cavitation - no wonder it sucks 825hp to reach only 37kts.
It's not a "TURBIN". That's head wear of a religion.
It's a "TUR-BYNE"
TUR-BINE
