Discharge of grey water
Being a "rookie" sailor, most of the rules and regulations surrounding sailing is new to me. I have a couple of questions about discharge of gray water, and I have not been able to come up with a prior discussion in this forum on point.
1. Is grey water included when discussing no discharge zones?
2. Does the "three miles from shore" rule that applies to discharge of black water also apply to grey water?
3. Since grey water comes from sinks and coolers, which are above the water line, is it necessary to use a vented loop in the same manner that one would be used for a holding tank/head set-up?
As always, your comments and suggestions will be greatly appreciated!
