You don't necessarily have to buy your own to get the full experience, though. In fact, you can find Seabreacher rental operations in Miami, California, and on various Caribbean islands. The company will also let you spend an entire day testing them out near their production facility for $1,000 (that fee will also go towards your purchase if you decide you actually want to buy one).
Can you hear that? It's the world's Sea-Doos in the throes of existential crises.
