The center wheel will have lite springs that disengage while towing (center wheel up). There will be a U shaped bar connecting the center wheels and two seats attached to the bar. When one sets on the seat, his weight will transfer to forcing the center wheel against the drive wheels. Two people will be twice the force. The axial force on each wheel will also have an mechanical advantage due to the contact angle. The center wheel will be an add on after I get the atv working.

I am using two hydraulic drives so both sides can go forward or backward independent of the other. The drives will be in the water with the hoses ran along the sides in the wings. The motors and pumps will be in the wings and not in the tube. The tub will be open except for the removable seats.

I am concern that the front drive wheels may just spin and the back wheels won’t skid.

Other features:
The wings on each side will be filled with Styrofoam so that even if the boat is swamped it will not sink.
To tow the atv I will have a built in tongue on the front that will lift the front drive wheels off the ground. The tongue is not shown.
This atv will be registered as a boat and a trailer.

As I work out the details I will update the picture.
