Respond with 2 boats with only 1 tow vehicle
Unique design lowers the top rack to allow the upper boat to be launched.
Another possibility ... A Connector Boat and inflatable boat. We call this the Complete Water Rescue Package
And yet a third option ... your two inflatable or two flat bottom boats 
Our 2000 series Double Stack Transport Trailer is the answer.
Solid, adjustable dual axles to allow you to adjust tongue weight based on the boats you are transporting and a heavy duty electric winch to lower the top boat into the water without even getting wet.
Interested in the trailer only until you can replace your watercraft, call (800) 737-2831 or email for details.
