Recent heat and hazardous smoky conditions outside prompted me to go through some old photos. Here are a couple images that may interest you, too.
My brother and I set up a booth for the Austrian FD Class at a big boat show in Vienna, and this is where those photos were taken. The photo of the full double bottom boat is a Leonhard Mader; one of the first models with full double bottom. The cockpit was open all the way to the transom where a narrow beam held up the rudder. What struck me is the simplicity of the controls back then. We already had lowers, but the extreme raking had not been fully developed; we were still sailing with the small spinnaker. Also note how the helmsman’s hiking straps are crossing, probably because the helmsman has long legs.
The second photo shows a Hans Mader all wooden boat from the same period but less advanced, with a half double bottom. This one has a curved traveller track. The controls are set up in a similar way and very simple. I suppose this boat had the spinnaker sack on the port side, which is unusual.
