I don't see anything wrong with a Tanzer for your first boat except that it might SEEM overwhelming at first in terms of size or having to handle two sails
. I remember when I was a kid learning
I avoided any boat with a jib
because they scared me, I wasn't sure what to do with that other sail out in front! I did a lot of my learning
on an El Toro and then a Laser then Capris and Victories (I know those names probably don't mean anything yet, I'm just pointing out I moved up in boat size slowly
.) And then the first BIG boat I got was 24'!
The Laser is a blast and super simple and you'll learn all the basics of how a sail makes you fly, and once your confidence is up then you'll fearlessly try bigger boats. It's a boat I'd still love to have!
But back to your question, I think the Tanzer is a good choice too!
Welcome aboard here and best of luck!
