Howdy, new to the site and somewhat new to sailing

I plan to purchase a cat next summer, as the wife and I are saving for a house this year. I am however going to be doing some crewing this summer on an H16 and possibly an F18.

Spent last Saturday down at the LNYC with one of their members getting in some seat time on the H16, we are going to be racing the PeeDee event in a few weeks.

The 18sq caught my eye, I like the idea of a uni-rig since most of my sailing will be solo, and I like the wide beam for stability. I am 200lbs, so I would imagine righting would be no problem...

How is the boat two up, just for cruising? They seem pretty rare, but I think through the good folks at the LNYC I should be able to find one when the time comes. Would it be too much to handle for a relative newbie with only 1 year of crewing experiance on cats?

My only other sailing experiance was crewing on a Morgan 38 back in MI.

Any insight would be great, thanks!!
