 \[dg]Skis cannot be powered, but are included here for their Suspension Factor.\\
 \[dd]Regardless of TR, suspension factor is 160 for two legs, 250 for three legs or 360 for four or more legs.

 To determine your land speed, multiply the power by your Suspension Factor, then divide by your vehicle's mass.  Find the square root of this value.  Drop fractions.
+===== Animal Power =====
+Yes, you can tow a vehicle behind animals.  The biggest down-side to doing this is that the top speed cannot exceed that of the slowest animal pulling the vehicle.
+To find the power of the towing animals, go to the [[drawingboard:fundamentals:scale|Scale]] table.  Find each animal's mass, in kilograms, on the Volume column, then read across to the Linear entry.  Total these values for all attached animals, and then divide by 40.  Yes...it won't be a lot.
+===== What About Hovercraft? =====
+Technically speaking, hovercraft are not ground vehicles.  They are very low-flying aircraft.
+Build your hovercraft as though it were an aircraft, but install some sort of Lift Equipment to counter out its mass entirely.  For a TR-1 or TR0 hovercraft, a lift skirt or wing in ground effect will do the trick.  For a more advanced hovercraft, take a look at gravity drives.
