Pete,

what is it you want to train for? Is to prolong your life and improve your health, or do you want to do something spesific like racing your F-16 competitively? (when is delivery btw?)


Of the sports I have been active in, catamaran racing as a skipper is the least physically demanding. Crewing is harder, but not really something you need to train hard to master. (except the guys doing Tybee/Worrel, archipelago raid and other similar events).
