## Abstract

The current invention offers an instrumental improvement to the prior art of USPTO Rudofsky U.S. Pat. No. 5,643,029 Motorized Surf Boots by providing a connecting Chassis Assembly that provides a rider the ability to lean into or “carve” through a turn (like a downhill snow skier or in-line roller skater does) while keeping each of the boards of the Motorized Surf Boots parallel to each other, at a predetermined distance from each other, and in-line with each other (meaning one board will not shift ahead or lag behind the other). Also included in this chassis invention is a device that provides an automatic and adjustable dampened spring back action, which serves to re-center the Chassis, thus the Surf Boots back into an upright or vertical position, in order to assist the rider in controllably ending the “carving” action and instead continue to move in a straight direction.

## Claims

### Claim 1

Apparatus comprising:
a front and rear Chassis Assembly, each of which include a commonly known “four-bar linkage” which interconnects and keeps two boards, or hulls, or other structures of multi-body vehicles at a fixed distance, parallel, and in-line to each other (meaning one board will not shift ahead or lag behind the other). Said apparatus provides the boards, hulls, or structures of multi-body vehicles the ability to lean into or “carve” into turns.
First means of attaching said apparatus between two boards, hulls or structures of multi-body vehicles.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein there is included a spring and/or damper device in order to provide an adjustable spring back or re-centering action of the said apparatus of claim 1.
Second means of attaching said adjustable spring and/or damper within the construction of said apparatus of claim 1.

### Claim 3 (depends on 1)

The apparatus of claim 1. wherein the components of said front and rear Chassis Assemblies can be quickly attached, or detached as desired, from the Boards of Motorized Surf Boots, Hulls, or other structures of multi-body vehicles using appropriately designed mounting brackets and/or quick-release pins.
Third means of attaching said mounting brackets and/or quick-release pins forwardly and rearwardly along said boards, hulls, or other structures of multi-body vehicles.
