Do we only have 2 water vehicles?

I want to do a story on a water planet and can only find 2 water vehicles.

Amphibious Modification (SM) lets you make any vehicle into a water vehicle. 1000 x sil and 1 HP.

There is also the fact that most speeder-type vehicles use repulsorlift technology and therefore fly/hover, meaning they can be used over the water. Now if you're talking submarine vehicles, then there is less choice.

I'm sure one of the Force and Destiny books has some submarine vehicles and possibly AoR Strongholds of the Rebellion, but cant remember off the top of my head.
