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?

Thanks for the referrences and the link! The Ghost is a cutting edge design and the decision to place the propellers at front of the torpedo hulls for reduced drag was clever. The Ghost will no doubt inspired future designer / builders.
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!
Have you got a photo? I've been thinking of doing a 1/72 model. I have a lot of drawings and photos of the ship I even made a tee shirt with the Kaimalino on it.
Years ago and not knowing a damn thing about naval architecture I was designing a 32 - 35 foot pleasure craft on CADD. Wasn't sure as to the length/width ratio, so I just went back to work.🤣🤣🤣
Thank you for your research work in the area of Archimedean buoyancy bodies in connection with interference and liquid wave dynamics. New technologies can only arise from old experiences and developments. One thing, however, is absolutely necessary: the additional fixed and adjustable fins and surfaces. And thus again too many areas outside the outer skin that need to be sealed and maintained, as well as vulnerable areas. The basic configuration is absolutely top-notch. No question about it. The only thing missing are the slotted openings open at the bottom for flooding the individual sections of the long buoyancy bodies. Because? Length just works better. Otherwise, very good work for that time. Peter
Can be a good platform for a yacht or transport ferry. With modern technology like solar on the entire roof, hydrogen electric hybrid power and modern computers that shit will be a hit. Just imagine the comfort and real estate you have.
certainly the one i was on was wonderful.... crossing the notorious irish sea you barely felt it move! dont really understand why it wasnt expanded to other sea services/cruise lines. Mine was the HSS stena line ship.

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.
I'm so disappointed we don't have aircraft carriers three times the size they are now handling twice the size aircraft with this kind of design what the hell happened? Just put a huge platform on top of two nuclear powered submarines that never have the ability to take on water ever again and you have an aircraft carrier that's the size of a small City in square footage
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.
n s Simply no need for that anymore. ICBMs and nuclear submarines pretty much made the necessity for such a ship obsolete as well as make such a ship the easiest target to pick off by any enemy missiles, ships or aircraft.
I wonder if this would be built today. With todays tech, ie Electric motor jet turbine drive with diesel electric generator. you could have shorter fins into the water creating less drag and even have four twisting rudders with a drive integrated into each rudder.
So where is it now ?. is it still in use ?. I would love to see the results of all the testing of what works and what didn't work out so well. ( I am a former commercial fisherman with a vessel design that would be considered to be a radical SES, that is unlike any other vessel that has ever been built yet). Now if I could only get someone in the know, to evaluate the design.
You can see this ship when going over the Coronado bridge. Going towards Coronado, be in the right lane, the person in the passenger seat can look down, its just as you pass over the water.
Don't underestimate resistance to new ship designs. It had happened before: Propeller vs steam. The inventor did some very bad seamanship in order provoke the steam warships to intercept him, but the vessels' speed was so much greater that he escaped interception them despite he repeatedly gave them many chances to intercept him. I can't find documentation for that event.

Annapolis should rebuild David Taylor Research Center into a high speed hydrofoil ferry design, research and production facility in order to build Marine Transit for the Chesapeake Bay. No third bridge !

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
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.
Interesting how a lot of promising concepts, that in these days are being "rediscovered", were born decades ago, making a lot of nowdays "innovative" companies not so actually innovative...and it is interesting as well how eventually the "winning" design is still the usual hull...
Lang did not invent this hullform. Canadian inventor Frederick G. Creed presented his design to the Canadian Patent Office and was duly awarded a patent. It is obvious to me that Dr. Lang pirated almost all of Creed's designs and should have been prosecuted for this piracy.

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.

Patent last for about 20 years, there after the invention is public . Copyright last about 70 years after the death of the ower.
a US patent was applied for and received in 1905
Later became the “wave strider” from Kentron of Annapolis.. and a single haul design known as the “sea knife”
So what happened?
I was wondering the same thing....
By old tech the jet suck fuel too much and the sound too loud, not efficient and easy target.
Maybe new tech can fix both efficiency and the sound
SWATH's birth.
Its good if you're not in an actual combat situation with it. One hit to the side from a Somali rpg will take out one of those 4 supports.
