This exquisite Thames racing skiff was built by Michael Dennett at Laleham. Apparently he has a tree of mahogany that he has been using for these boats, which are built in matched pairs for operations like Dittons Skiff and Punting Club.
Several of these skiffs were at the Great River Race. I was impressed by the complex series of actions needed to bring the blades in. In action, they are held down by a twisted cord halfway up the rowlock, so to get them out the entire loom and handle must be slid out and the blade raised over the cord. The rowers could do it in a swift, neat and practiced movement but it must be much easier with a swivel, when you can just turn the blades parallel to the boat and slide the handles forward. Each to his own, I suppose.
