Well done Scotty. You beat me by over a knot peak and about a knot 5x10. Problem with this watch is the file has loads of blips that need deleting using a pc.......and cant be arsed dusting off my pc to do it. Will find a way with a phone somehow! My peak on my watch is currently 259knots with a second of 182m though these were while I was waterstarting between the boats and my hands must have been in the water.......
