I was involved in a fast catamaran ferry build in Norway that used one of the first integrated propulsion packages from ServoGear. That concept...
I'm with you there. I bought a heavily built early 1980s 25' Deep-V Rampone that had originally been built with a pair of Volvo 140HP gas engines,...
They do both require prime movers and lift fans or some other sort of compressor to supply pressurized air. The ACV and SES fully capture the air...
We design and help to construct hovercraft and surface effect ships...have for 35 years. We were also involved in a number of surface drag...
This thread invites confusion because it has included discussions of both air lubrication and air lift and they are two different things. Air...
You've described, more or less, what was attempted on a few catamaran hull designs and at least one mono hull. All were failures in terms of any...
I'd be interested to know more about the successful examples you are referring to. Always good to see the successful ones.
We launched/commissioned 15 of that Cirr120P SES series, in Noway, from the mid 80s though about 1992. All went in to passenger service and, last...
Speaking as someone who has a few SES designs to his credit; the effectiveness/efficiency of the SES has never been debated since the 1960s when...
That reminded me that it was a Russian guy that was pedaling licenses to add air-lubrication to various hull types. I've since forgotten his...
We played around with a number of air-lubricated/pressurized-air cavity craft over the last 35 years or. Key results: Air lubrication schemes...
Full dynamic foil support of man plus machine at 3 mph ..and the ability to sustain 3 mph+ plus is definitely impressive. I know my old self won't...
I'd still like to know how much buoyant lift the foil and structure volume provides.
Certainly appears to be a fair amount of buoyancy involved there....
Based on that power ratio, it would be more accurately an electric-powered pedal-assist bike. I like it though..as a hydrofoil designer/advocate...
And another that I've worked closely with on some very large and prestigious yacht projects.. The story of Donald L. Blount and Associates -...
I have not worked on any of their recent projects, but have worked with Baron Rohl on some very large yacht projects that he managed. He has quite...
One of the first things I learned about designing and testing foil-borne craft were the pitfalls involved in trying to employ any of the more...
Maybe I missed it in the discussion, but every vessel we've been involved with that used foil lift - any lift at all - had a cross-over point...
The seakeeping of our 43' foilborne craft was amazing. I wish we could have afforded to keep it around as a pleasure craft after the trials...
