Well, the biggest difference I’d have to say is maneuverability. Jet skis are a lot more like slalom skiing and require a lot more practice to ride well standing up and turning it results from re-positioning of the rear water jet to the left or right, so, basically you’re kinda pushing the back end around. Same thing with a SeaDoo, although a jet ski since it’s smaller and narrower is a lot more maneuverable that a SeaDoo. The wet bike however is guided by turning the front ski. I found that doing power slides across the water, a lot like a flat track rider does on a bike was a lot smoother on a wetbike than on a jet ski. Jet skis tended to skip across the water like a stone what you got them sideways.
In the end, they’re all fun and the newer SeaDoos are scarily fast. The last one I rode topped out at 54mph (~87kmh) and doing 180’s at that speed on the water is like riding an insane bull into a burning barn…on the water…or something. In the end though, my fondest memories and the most fun I’ve had on any personal watercraft is that wetbike. I’ve still not ridden anything on the water quite like it.
