Curious as to why you were under jib only? If I only want to go one sail, I put up the main to get it out of my face, all bunched up on the boom and draped into the cockpit, although I think I'm the only guy in the world without a roller furling jib. (also the only guy in the world without lazy jacks)
My 17 foot boat sails fine with only the main. I'd want both up for 0-5 kt puffs.
But the real story here is... WOO HOO! You were out in a boat and had fun. Looks around the forum here. There's some really great threads of things applicable to small water sailors in <20' boats. (and it's neat to read the stories of a 46 footer avoiding the reefs outside Bermuda in a storm) Have fun!
Keep the expenses low and the good times high.
