Chassis to connect motorized surf boots, or other multi-body vehicles

A carving apparatus of a multi-body vehicle comprising:

• a front and a rear four-bar linkage which interconnects and keeps two boards or two hulls at a fixed distance, parallel, and in-line to each other;
• said carving apparatus providing the two boards or two hulls, of the multi-body vehicle, an ability to lean into turns keeping the two boards or two hulls at parallel angles while rotating and leans into turns made by a rider leaning into turns while riding the multi-body vehicle;
• wherein the two boards or two hulls provide parallel stabilization for both the front four bar linkage and the rear four bar linkage of the multi-body vehicle by having two parallel bars of the front four bar linkage and two parallel bars of the rear four bar linkage rigidly attached to the two boards or two hulls such that an angle of the two boards or two hulls defines an angle of the two parallel bars of the front four bar linkage and the two parallel bars of the rear four bar linkage allowing the rider of the multi-body vehicle to steer the multi-body vehicle by leaning into a turn and rotating the two boards or two hulls in a carving action.
