Talking saily things smallest walker bay 8' ish and a Grimsby trawler 83.9' and 83tons including the huge pole at the front. Single screw and no bow thruster bloomin tricky to park.
Smallest was my first boat - a 14ft Fletcher. Largest? Princess 23m. I have sat at the helm of Redjet 4 and the Fastcat to Ryde, but don't count that, nor the Portsmouth ferry across to Fishbourne. Have stood by the helm of HMS York, but then she was moored up in Pompey Harbour so that don't count either /forums/images/graemlins/grin.gif
