G-Cat is the brand name. You may not see them in ads, because they are not as common as other brands in USA. But they are good, tough boats, loved by their owners. Models include G-Cat 5.0, G-Cat 5.7, and I think also a 20-footer or even 21-footer.
The G stands for Geissler, the original designer/builder.
There are quite a few different models, the 5.0M Mk II and 5.7M being the most common. The G-Force 21 and G-Cat 6.1M are pretty rare, and I've only seen a single G-Cat 5.0M Mk I
I've also only seen a single G-Force 36 Sport Cruiser but that's beyond the beach-cat range.
There is a G-cat 5.0M Mk II with a trailer and new sails for $2200 listed in the classifieds. I've spoken with the owner and know that the sails alone cost him that much.
The G-Cat is a boardless yet symmetrical hull design with three crossbeams. It relies on it's Deep-V hull-shape to go to weather, and I can attest that it's a very functional design. My friend Ralf Cole of Bradenton Beach Boat Rentals only uses G-Cats in his rental fleet due to their sturdy construction and easy-to-maintain design. He takes people who have never been on a boat before and teaches them the fundamentals of sailing in 15 minutes on the water. Off they go and when their time is up they sail back to the beach.
If you follow the race results around Tampa Bay you will find G-Cats still placing well against much newer boats, and Hans Geissler still sailing them.
