G-cats are nice, sturdy boats and they are great for non-sailors because they have a really open tramp and a forward tramp! I have only seen a few and I've owned one for a short while, but I was impressed.

There are two versions--one is a rental boat with a shorter mast and the other is a standard G-cat. If you get the rental version, you may not be happy with it, but it would be about impossible to get a used stock G-cat mast. However, I replaced my 5.0 mast with a Nacra 5.2 mast. I had to move the tang and all connectors, but it was almost the same size extrusion. The mast base even fit in!

The boat has enough hull to it, that it is screaming for a spinnaker or Hooter sail!
