Cargo-ship or explorer

There's always something going on at Tradewinds. Yesterday, while I was tanning on my new and delicious Ushuaia, this thing was roaring about by the west-side pier.

Cargo...

Never saw it before, but it does look kinda interesting with all the boxes, cranes and what not gizmoes stuck on it. Plus the name is funny. BTW: What are those yellow spots there on the side?

... or Explorer?

In picture two there's a platform of sorts on the starboard side. It could maybe be used for launching some kind of deep sea explorer equipment. Not that we have a great deal of deep seas to explorer. I wonder wat is the deepest spot in Blake? What's the deepest spot in all oceans of SL?
