Looks can be deceiving. The pint-sized Yamaha EX packs a surprising amount of cargo space, whether it’s for large tube of sunscreen or a beach towel. Sea-Doo ST3-based models have awesome convenience to access the bow storage compartment (as the handlebars lift up with the top console), but can’t carry as much as you might expect – unless you buy a Fish Pro or the giant cooler that goes on the rear deck.
The Kawasaki Ultra platform that’s been around since 2007 has by far the most storage of any personal watercraft on sale today. But that advantage only applies to the non-supercharged model, because for 2022 the supercharged Ultra 310s have a new top deck. Kawasaki says the 2022 Ultra 310’s class-leading storage has been “completely rethought.” They got that right. It’s now smaller. But at least it’s much more usable and still one of the best in the market (with storage behind each of the front fairings).
To take some of the guesswork out of which model has the most room to carry stuff, we’ve gone through the manufacturer websites so you can save your data – and perhaps your sanity. As you can appreciate, this took ages to compile. In one instance, one of the manufacturers (Kawasaki) contradicted themselves on storage space for the same craft (2022 Ultra LX non-supercharged), depending which website you searched around the world.
We’ve just gone with the total number for the US. We weren’t able to find a number for the non-supercharged Ultra’s space under the seat. It’s not in the owner’s manual either. If you find out let us know. Meantime we hope Kawasaki reads this and can clarify the numbers of the old Ultra top deck (splitting the bow, glove box, and underseat compartments).
Other takeaways? It might not look like it, but the latest Yamaha FX series has a great level of storage capacity and probably deserves more credit than it gets. And incredibly, a Sea-Doo Fish Pro Scout has more total storage than a full-size ST3-based Fish Pro Sport/Trophy. Check out our list and see for yourself how each model stacks up.
