First time on a sailboat, someone told me to grab a sheet. I thought "What? Nap time already".
I immediately took the CYA Basic Cruising, bought and read everything I could find. I hate being ignorant (insert smart a*s retort here).
Vastly easier to learn if you go sailing with someone [who knows how to sail] first. Then you get infected with love of the three Ss: Sea, Sailing, Spending.
