I may not be as quick as I was when I was a student, but I'm not bad at research now. I've graduated to mentor status, which means I'm too slow to do much but race sail boats. They only go 5kts or so on a good day. :)
Not being a sailor, but a participating guest on several occasions, it seems the objective is to get as much out of the wind as you can - and that can be very satisfying. We take our pleasures when we can - and speed is "relative" - age forces many adjustments and, for some of us, really noticeably is that associated with speed.
May you have a good wind on calm seas (is that possible?).
