If you wish to find the biggest lobsters do SCUBA diving at the town sewage outflow.
How far offshore at the sewage outflows in the US of A

We may use inland waters differently. Generally I would use that to mean fresh water (lakes etc). I don’t know if that is illegal here but it probably is. Inshore waters we don’t define a distance before sea cocks can be opened in UK watersI don’t know any UK marina that would find black water discharge acceptable.
(I didn't specifically say in a marina. My understanding is that discharge is illegal in UK inland waters, as it is in US inland waters.)
Correct, although they do exist in the busiest areas.(My understanding is that pump-out are few in the UK,
Anything <25yrs old will. Many older ones do. My guess is not many “marina” based boats in the UK don’t have a holding tank (or chemical toilet).many boats don't have holding tanks,
If everything that goes out the sea cock is natural and biodegradable it is difficult to see why discharging it from the boat directly vs pumping out ashore processing at a sewage treatment works and discharging at sea (they don’t discharge clean water). It probably more important that people think in terms of direction of tide, and any enclosure that some distance from a harbour. That’s the problem with pumping out bilges in some marinas the water doesn’t get exchanged within the harbour efficiently so whatever is in the water stays in the marina rather than being diluted, dispersed and digested by the natural processes which mean that pumping out at sea doesn’t get too many people animated.and pumping just a few miles outside the harbor is normal.
That's a red herring.If you wish to find the biggest lobsters do SCUBA diving at the town sewage outflow.

This is correct.If enough water is coming in to justify an automatic bilge-pump, then something needs fixing - and it isn't a bilge-pump.

I’d have to fix the leak in the sky to stop my automatic pump being needed.This is correct.
An automatic bilge pump isn't for normal everyday use . It should only be required when a fault has developed.
I believe that is for ships, not pleasure yachts. Please share where the above came from.UK boat discharge regulations:
Sewage
Treated sewage: Can be discharged anywhere at sea
Comminuted and disinfected sewage: Can be discharged at least 3 miles from land
Untreated sewage: Must be discharged at least 12 nautical miles from land
Discharge rate: The vessel must be moving at a minimum of 4 knots when discharging
Discharge location: Avoid discharging in areas with poor tidal flushing, shellfish beds, or bathing beaches
Holding tanks: If a ship has a holding tank, it should be used and emptied at a pump-out station or when more than 3 miles offshore
Presumably you’d also spot if the water it was pumping was polluting the marina. Clearly owners should be taken to task for that, though surely theres no harm in pumping rainwater out of most peoples bilges.Marina staff here...No, we don't check or ask if you leave your bilge pumps set to auto. Yes, we do regular pontoon walks and would spot if your boat was permanently pumping and let you know ASAP.

How would you know that it was not AC or Heat Pump? Serious, honest question. Very common here in the summer, even when the boats are unoccupied for weeks.

Then I'm unlikely to see it unless it's noticeably oilyPlus quite a few boats pump out below waterline ...

Honestly, we're just trying to help our berth holders out here.
