Just out of curiosity, how much of the loss is due to air resistance ?
You might try driving at half the speed and taking similar measurements.
A little math will tell you what percent comes from air.
I think your assumption that it comes from air is reasonable. But before
you launch into work and spending money, it might be good to know.

Subject: [EVDL] Improving EV range aerodynamics when towing a boat or
trailer.
Hi Folks
When I tow my 6x16 H20 ski boat 1480lbs behind the 3600lb Bolt or 4400lb Tesla,
watt-hours doubles and associated range is cut in half. I thought the Tesla y
would be better due to the weight ratio but measures about the same reduction
driving the same 2 hour path to the lake. I could put the windshields on
hinges but that’s quite a bit of work. Thinking covering the boat with a high
speed rated cover to remove the seating area cavity and redo the test
measurements. Any other ideas? With 316 mile Tesla range cut in half, I feel
comfortable with a lake up to 70 miles away but there’s some near Roanoke that
are a bit further.
Stay Charged,
Mark
