Had (what is left of it is in a yard somewhere on the Loire in Nantes) an LB15, the first boat designed by Yves Loday (Barcelona mixed Tornado Gold). I was a bit heavy for it but once I got the Mylar main I could hold it in a breeze. Never got the rudders sorted - they used to pop up at speed... I used to sail every day before going to work at one point so I got quite good at it. Those days (late 70's early 80's) we were sailing against all the big boys who weren't quite pro yet but might as well have been: Le Cam, Pajot brothers, Loday, Poupon brothers... You learn humility. My crew went to high school with quite a few of them, damned good sailor she was, "paré", "à virer" and it was done, magic.
My favorite trick on the river when solo was to gybe with the lee bow stuck in the water up to the beam and with a little flick of the hips I was off on the other tack, I did have some boat handling skills. I scared a windsurfer silly one day, it was squall after squall so I was sailing out, waiting then riding the squall back into the bay. He had never been on a cat, I'm not sure he ever tried again. I said "we don't know each other but when I give the word get back here with me as far back as you can". He got the picture really quick when he didn't move fast enough the first time and the bows went in up to the front beam, after that he was sitting on my shins
You couldn't see the boat, it was covered with spray and froth.
