From one grrl to another...
Since the subject of your original thread got totally hijacked, I'll attempt to answer your question from, well, the feminine angle.
My 1st boat was the Hobie 16. It's not a bad choice for a first boat, not at all. There's lots of them out there, they're simple, singlehandable, etc. you've heard all those arguments I'm sure. They are also prone to pitchpole, and they're not the most comfortable of boats, to me, anyway.
That said, once I sailed on several boats...
Read that as advice #1: sail on as many type boats as you possibly can. If your pic is any indication, you should have NO PROBLEM with invitations ;-). From that experience, you will make a FAR MORE INFORMED decision.
...I, through the kindness of an individual and just plain luck, ended up with a NACRA-made 18 Square.
I love my boat, for several reasons, including: first, she is, although a more modern design than the H16, still simple. She is stable in her beaminess 3.35 metres, more or less. I am able to right her with the use of a righting pole which is, in my case, an old windsurf mast...
Advice #2: The windsurf mast is a good choice because you can cut it to length, and your weight will dictate the length you'll need. It may hang out the back of the trampoline, but aesthetics give way to necessity.
...albeit a 23-year-old boat, she is quite competitive still, especially with my new sail. She is comfortable in her ride, and although made to singlehand, I can carry another person, although not in competition. Read this to mean, she is VERSATILE. Do you race all the time? I bet you're probably interested in casual sailing, so that should also dictate your choice...
Advice #3: You may ask for people's opinions, but the saying goes that 'opinions are like a$$holes: everyone's got one, and they all stink.' Keep that in mind.
I have found that although with respect to the racing scene it would be nice for everyone to have the same boat, unless your main object IS racing, you should purchase your boat with ALL her uses in mind. Your best guide is experience, I honestly believe that.
