I'm not aware of any difference. The one you see used in our DIY Oil Change articles is mine. I bought it at a boating supply store here in Atlanta. They had a whole stack of them and they were ALL intended for boats.

On the box mine came in it says "Big Boy Topsider MVP". "For your Boat. For your vehicles. Around the home" It is rated at a 2 gallon capacity but, it holds the 8 1/2 quarts from my E430 just fine as long as the Topsider is on level ground.
