You can go on stage but your afraid to sail? Fear of stage is one of the biggest fears anyone can overcome! (I used to do allot of public speaking)
By making a post here already shows your getting ready to overcome your fear. I'd like to suggest you go! Have a friend or ask your marina to have a boat nearby in case you get in trouble. GO! (pick a day with light air!)
Do it all in stages!
Know all your gear, safety gear, how to start engine, things to watch out for. how to read your instruments etc.
Docking, tying off, handling the boat around the harbor.
motoring, navigating, learning the "rules the road" etc.
Leaning how to raise sails, douse sails, furling and flaking.
get comfortable with moving around your boat while underway. How to tie off and or use the autopilot.
Make sure you get the boat set up for single handing. it's not terribly expensive to run the lines to the cockpit.
If all this still intimidates you.. try taking a sailing course. Don't rely on hubby. Hubby's are good for lots of things but not teaching!
as evidenced by so many guys here on sail net! They always advise couples to take separate sailing instruction! Reading is something I love to do also, but sooner or later, you gotta get out there! By the way I single hand a 30ftr, or least try to!
PS: there are people that teach how to handle and sail you on your boat too if you can find one.
