KTMCD shares good advice. "Day and weekend trips to begin
Take ready to eat food. Buy a whole BBQ chicken (if you eat chicken) and it can be good for lunch and supper.
Bread and cheese and meats are also great. Take lots of "comfort food".
There were days when we went out to the boat on Friday after work, had supper on the boat, had wine etc on other boats moored close by, slept, had breakfast and then had a short day sail. Getting back in time, in the light, to secure everything and go home.
Take little steps until you feel good with them, then expand your horizon a bit at a time.
And remember - nobody yells! You are doing it for fun, so it should be fun for everybody.
