Rowing and Towing

No, this isn't my car. The picture was posted on Proper Course, where ace Laser sailor Tillerman says he doesn't know much about rowing but isn't something wrong here?
I spent much of the weekend towing stuff, as it happens, including taking our majestic 30ft long Solent galley Bembridge to the Hamble. Proceeding at a stately 60mph past a motorway turnoff, I looked in my wing mirror and saw a hot hatch zoom up on the outside lane trying to overtake me before the turnoff. Then he (yes, of course it was a guy) discovered he had totally misjudged how long the boat is and had to hit the anchors and drop round our stern so he could make the turn. Much slower. HAHAHAHAHA.
Which reminds me. Doing the same trip a few weeks ago with our Clayton skiff Gladys behind, I was overtaken by a house. It is very alarming to look out of your side window and see a front door drifting past just a few inches away (it was a very wide house) at a good 70mph.
