The other at 26 ft. has been used both with a 50 hp motor giving 20 kts and with a rig. No attempt has been made to separately power the wheels. The 26 footer takes two people to push on flat, hard sand. We are confident we can design the basic structure for any size. We believe the Amkat can be effectively powered with one hydraulic pump on the engine to drive both the propeller and the wheels.
Hydraulic motors are available to fit within the hub of wheels.
Some investigation is needed to assess and check the availablity of suitable equipment to achieve the required performance on water and on land. With the hydraulic motors within the hub of each wheel the connection to the pump is via flexible hose. It would be possible to fit rubber tracks to conventional tyres if required to operate over soft ground conditions. The sophistication of the controls will depend on the application and the performance required. Steering will obviously present a challenge.
