I crewed on the S.S.P. Kaimalino. It was the most interesting job I ever had at sea! Those T64 Gas turbines could burn an awful lot of fuel in a hurry! With the chain drive, I was told a sub could hear us operating for hundreds of miles. Those drive chains had to be hoisted from their wells and inspected, course by course, every 100 hours. A giant pain, but great overtime! If you went down in the port bow where the bubble was at night, the bioluminescence from the critters in the water put on an endless light show that looked as though you were going into hyperspace! It was always fun watching dolphins swimming in the bow wave except when they crapped! Great memories of this ship!

Under way, the dynamic flight control would cause the ship to "fly" at a pre-set depth and the only motion you felt was a sort of elevator sensation as the ship went up and down in a level attitude. When at rest, the ship would go beam to the wind , but was un coupled to the waves. The ship would roll one way, or the other for two, or three waves and then start to roll slowly the other way. In large seas, the roll could be around fifteen to 20 degrees. In very steep seas, the bows would crash into the tops of the waves and throw a pretty impressive spray over the bow, especially when the ship was head to wind. We had an admiral and his staff on a dog and pony show ride out of Kaneohe Bay once. The admiral was on the bridge steering the ship and a few of his staff where on deck. Just as we got the the sea buoy I spotted a very steep wave approaching fast. As the ship plowed through the wave crest, , I dove down the companionway to stay dry! The once dignified naval personnel, however spent the rest of the trip wearing wet white tropicals!

Rad Ching remember doing motion sickness studies with the USCGC Mellon (717) in late 70's. Always loved the concept and still believe it's the future. Don't understand or ever been told why the concept never became widely accepted? Not sure, last I heard she was decommissioned and in the Chesapeake mothballed? The chain drive was always an issue for me. Wondered if water turbines or jet drive would be the way to go, as they are highly efficient and great on fuel consumption? The Radisson Diamond (Asia Star) would pull into San Juan weekly. It always gave me a chuckle hearing folks call it a catamaran. 😎 All the best.

In the 80's the Navy proposed a sea control ship based on SWATHS. I think they were referred to as light expendable helicopter carrying sea control ships. LOL I remember the word expendable, but wonder if I mistook it for expandable. The University of Hawaii has a SWATHS research ship and I've heard lots of good things about it. I think if the Navy ever goes back to the jeep carrier concept, a SWATHS would be a pretty good choice!

No. Just make the submerged parts comported (If there is a hole, water only gets into one area) and allow the struts to be released and then a backup propulsion system in the platform. Or, if you really want to do something good, have a 3 strut version of this instead of two. The outer struts take the torpedo hits, while the middle strut has the engine and is unaffected. Also, it's not like there wouldn't be armor, or that those types of problems wouldn't occur in the current ships.

why did this not catch on?

For those wondering why this ship design isn't more broad... the video gives pretty damning clues about it. If this ain't enough, go watch videos of Japanese ferry boats at work, the only highly active area for these. It basically screams in your face why this type of boat isn't used. If that ain't enough either, then one word should: maintenance.

Just think how stable and fast this would be with today's computers . I could see it as refueling and rearming station for the F35B . That would be way cheaper than a 13 billion dollar Ford class that can't get close to shore ever . I'm sure the military would call my idea a force extender like an aerial refuel aircraft but it's over the horizon out of sight and of of being a target

Later became the “wave strider” from Kentron of Annapolis.. and a single haul design known as the “sea knife”

nice to see model predictions were proven in real-life trials !

If the front and rear struts were joined together, the wave motion would be cleaner and there would be less drag. As it is the rear wave of the front strut is causing a higher wave to the bows of the rear struts and the wave under the hull is very ugly indeed. There are no benefits in separating the front and rear strut in a dynamic sense.

Hi Everett - you are right about Frederic G Creed (most famous for the teleprinter company he founded), He invented the SWATH (small-waterplane-area twin hull) some time before 1938, when he presented it to the British Admiralty, and was eventually awarded a British patent for it in 1946 - so the patent probably expired before Thomas G Lang got started in the 1970s.
