The guy has a agricultural contracting business, so I guess he used some mechanical stuff from that fleet to transfers the power on the rolls to thrust of the cat. Attachment 98880 - - - click pic to enlarge
For more info about the car + cat combination he has posted two E-mail addresses at the bottom of this page
Again thank you for those pictures as it has given many vision I needed with not having to make a proto type to see it in action which has taken me to the next stage that is marketability “cost”
Some models I will by pass the vehicle propulsions adaption system and add a simple out board, as with the cars weight on top it will not plane even with large HP and a course pitch propeller on a 15hp four stroke for torque to punch through the water.
this options is when car is not on top of the pontoon it can be used as a speed boat as a 15hp out board can easily plane the pontoon.
I can buy reliable 15 hp four strokes factory price in China plus the folding self-trailer pontoon that if made in production could be sold retail price for complete motor and pontoon with built in trailer system for under $10.000.
I look at the future market that will have frequent floods because of the climate changes and sea levels rising, hence the name Myark “Noahs ark” but also an affordable leisure and commercial boat for today’s standards that has options such as sail, or make car amphibious as it’s a good feeling to be able to keep going and no doubling back to pick up boat trailer especially a mobile home that can land on a remote island and then use the pontoon as a speed boat as demonstrated on an early proto type Myark, Youtube movie https://www.youtube.com/watch?v=DDfSuAtiVkQ
also to have air-condition or heater from car as well as lights suspension window wipers and comfort plus the electronic appliances and luggage space safe and dry.
The advantages of folding the pontoons are narrow on the road and extra width on water place saved garage or sections space and the saving of weight when towing.
The picture Myark folding trailer barge with van on top are roughly the unfolded shape of the new version Myarks and the picture you have sent is much closer.
The pictured Myark size unfolded is 6.m X 3.m
