I'm rambling. I'll stop now. :-) Don't ask me about sharpening or sailing or I'll never shut up.
My knowledge of sailing is zilch so that won't get much conversation going with me.
On sharpening my setup starts with the Veritas® Mk II Power Sharpening System and/or a granite block with a strip of adhesive backed sandpaper of ~320 grit for heavy work such as nick removal or back flattening.
After that it is 1000, 4000 & 8000 grit water stones. Mine are Norton and King. They work well for my needs when it isn't freezing weather. If it came upon me today to purchase some stones my first thought would be to buy from Stu at Tools from Japan. There has been some issue of late with family health and it might not be the quickest way to acquire stones.
My cold weather set is made up mostly of odds and ends acquired over the years. Oilstones are not as fast cutting as water stones. My favored "quick removal" oilstones are some old Washita and soft Arkansas stones. The middle stone is a Dan's Whetstones hard Arkansas. My main finishing stones are a couple pieces of translucent Arkansas bought at a gem an mineral show. Also purchased from lapidary supply venues are a couple pieces of jasper. Jasper is as hard as translucent Arkansas but has a finer structure. It is more of a polishing stone.
Like Malcolm, get me talking about sharpening and you will have a hard time getting me to shut up.
