There have been several SolCats on Lake Tavis over the years. The one guy who sailed the most was a good sailor to start with, just came across a cheap SolCat (but his kid worked at the sail loft and could fix the tramp & sails for almost nothing.

I do not think a Solcat is a good starter boat mainly for the following reason - hard to find parts. Although right now on our Craigslist, there are two or 3 all for less than $700 =$800 each. If I really wanted a Solcat right now, I'd go buy the best two of these 3 currently for sale, and have lots of spare parts.
It is not a bad design, just a little low freeboard, so you'll definitely get more spray than with a NACRA. Top of hulls are flat so when it starts to dig in, it can pitchpole like a Hobie. I'd consider it a lake boat, maybe OK on a flatwater bay, but it should *not* be considered a surf boat. You will definitely want to protect the bottom of the hulls when lauching, if you don't have a real nice soft beach to launch from. You can either get beach wheels $$, or here's a cheap alternative - buy 3-4 pieces of 10-ft sewer pipe (4"diameter, thinner wall than schedule 40). Throw these pieces on the ground under the hulls when you pull the boat off the trailer onto the ground, or when you pull onto rocky beach from the water. The pipes will keep your hulls up off the rocks.
Much of the rigging & settings you could copy from advice for an old NACRA like 5.2.

Good luck
