Is Gibbs Quadski still in business?

I'm curious to know if Gibbs Quadski is still operational in the market. I understand they were once known for their innovative amphibious vehicles, blending the thrill of both land and water adventures. However, with the ever-evolving landscape of the automotive industry and the increasing competition, I'm wondering if they've managed to sustain their business. Are they still producing their unique Quadskis, or have they shifted focus to other endeavors? It would be great to get an update on the current status of Gibbs Quadski.
