If it’s a dream Terry don’t leave it to late. Sometimes the end of sailing comes before we are truly ready for it. This past summer showed me that I am not as spry as I once was to the point of being less safe than I would like.
A right coaster, it is easier sailing if you stay inland. I sail the Hudson River when the sun shines and the winds are gentle. At 74 I am still somewhat spry. It just takes me a minute to muster the energy to get up and do something. I sail a Capri 22 set up for racing which I do not do. The boat balances well and allows me the extra time it takes me to get to that snarled line or such. I can usually count on the winds blowing like snot an hour into my sail or not blowing at all. If I see weather developing in the mountains to the west ( the ones that Rip Van Winkle heard the bowling) I run like H**l.
Every Ski season I ask myself if I can really do this. After first run, the answer has always been yes! Skiing maintains body strength and balance, good things when sailing a smallish day sailer. Missed last season because of Covid. The most masked up people are skiers. Even on a chair there is no real contact pathways unless the skier is intent on spreading their wealth.
Back to the question at hand, 80 seems to be a limit to single handling. Not crewing, I hope.
