Towing economy

For fuel economy: Is it better to tow a RIB without a cover but with the light board on an A-frame, or use the boat cover (and have lights under the engine on the trailer)?
I've gone to the south of France and back and the result was 22mpg. Single axle trailer, 6m RIB.

cover was not drastic on my 5.85 towing as it's in the slipstream of my shogan 32-33 mph 3.2 ltr diesel

Gotta have a decent cover to tow with one on-the DucksBack ones balloon right up. I tried it once. Never again.

Lights should be on the trailer for legal purposes, and they're probably more secure there too.

7m RIB 550M + tows on occasion ...no cover..= noticeable improvement in mileage and Performance..with no worries about the possibility of looseing it on the Motorway!..
Shorter trips not bothered,but then you don't need a cover anyway!

Light Tarp carried to cover up if staying over en-route.
I often go to a power wash when nearing Home now to give the Boat and Trailer a good wash off....Short Drive to Dry..Cover AND Tarp when stored works for me.
...Bugger for Flies in the Summer though!...but a decent Polish soon sorts that.

How are you guys getting such good numbers on mpg? It's either super-not-aerodynamic (Bombard DB600 Explorer; it has large diameter tubes compared visually to other boats) or somethings wrong. But what else could be wrong - tyre pressure 4.50Bar (max that's written on a tyre) and the wheels spin without any brake friction.
Or maybe it's just what it is and I should stop worry? The most annoying thing on the trip to France was the amount of stops on petrol stations.

Are you sure this is with the boat? ;-)
I thought Shoguns did that mileage by themselves, without needing any help from boat+trailer combo ;-)

Ford Kuga 2.0TDCI 180BHP. It does 40-45mpg solo depending if it's me or the wife driving it.

When towed behind Mondeo (also 2.0 TDCI) it did 25mpg with the boat, 50mpg solo.
