I read through the Sabre dinghy construction and fitting out notes, and realised that the rudder blade on my boat is distictly non standard. The notes specify essentially a rectangular shape. Mine slopes back from the leading edge. I asked Jim at the Dinghy Shop about it when I left standing rigging there for replacement. He said I could get away with it, as long as I didn't start winning. Not much chance of that, but I will replace it anyhow.
Just as well I discovered this before I put too much effort into patching the old blade up. I have been researching NACA 00-- foils, not that I have much confidence I have understood much, and I am laminating up some ply to the requisite thickness. Tomorrow with the help of some templates I will see if I can make a passable rudder blade that could pass class measurement.
I wonder about the centreboard though. I will have to retrieve it and measure. I bought some closed cell foam for the trolley, and new lettering for transom on order, so with luck we might be ready to go soon.
Looks like Friday might be a possible sailing day weather wise - and I have plenty of boats to choose from.
