This is my setup for vacation for transporting my Jon boat. I built the boat specifically to fit on top of the trailer, then we put our bikes and luggage in the trailer. I tow it behind my model 3 Tesla and once we are able to travel again we will take it from Toronto to Florida for vacation. Being an electric vehicle, towing takes a huge hit on range so every bit helps.
The area I want to improve is the flat front part of the trailer. I was thinking just a round fairing below the boat kind of like this trailer

Any suggestions?
