About the Winner
Anything attached to the outlet of an industrial pipe is likely to have some level of grunge factor. Aaron Rocklin has developed a Bilge Sock designed to eliminate the release of hazardous liquids into lakes and oceans. The sock absorbs things like gas, anti-freeze, and oil from the sump of the boat/yacht. One boat's discharge is another man's grunge, in this case, Rocklin's. He's happy to be doing his part to help the rivers, lakes and oceans, but he's definitely contending with some grunge in the process.
