After collision, did you get a chance to analyze what you did wrong?
There are lots of ways of messing up a tack.

Fresh Breezes- Doug King

Well, I was trying to tack out during a period of little to no wind. As
well as it being my first time out, I was also trying to explain things
to my 7-year-old. [another mistake, splitting my focus] When I was
making the tack to where the wind "should be coming from if there was
wind" I stopped the turn too early. My mistake wasn't immediately
obvious to me because there was no wind. I was only about 5 feet from a
boat tied up at the end of another dock. A breeze picked up and back
winded my jib and I immediately knew I screwed up. The bow was blown
starboard and I couldn't stop it. It was all very slow and frustrating.

So there I was blown against another boat. Even more frustrating, I
couldn't figure out how to get off of her.
