I guess it won't be too long before we have a new group of younger sailors who have done one or more nonstop, single handed circumnavigations, without leaving the comfort of their favorite easy chair. Heck, they should do it using celestial navigation, while they're at it.
And here I thought the best new product for us sailors was a water maker so one can have a nice, long, warm shower any time one wishes, at sea. Of course, if one is using a program, there would be no need for a shower, as not one hair would be out of place, even in the biggest gale.
For the last six decades I've been responding to those who asked, that the only way to become a good sailor is to sail a lot on a reasonably small sailboat, then a great deal more sailing. And even more, etc. My, how times have changed.
