California Commercial Dive Boat Discharge

[kaerius]

A much worse water pollutant(and it's also horribly gross to swim through) is the exhaust, and sometimes engineroom runoff expelled by diveboats. Let's just say that most boats don't run on the cleanest fuel posible in the first place... in fact many boats run on what's basically oil refinery waste product(look up marine fuel oil aka heavy fuel oil, it's what's left over after turning crude oil into gasoline).

Dive boats will be burning #2 diesel, pretty much the same distillate fuel used in a lot of European road vehicles. Unless you're diving from a container ship or supertanker you aren't going to be exposed to bunker fuel exhaust.

Sorry, Commercial dive boats burn the same fuel used in trucks, farm equipment and diesel cars and pickups - #2 diesel fuel.

Bunker fuel is used in the large ships.
