The answer in the UK is screw in moorings and boats are still permitted to use their own gear however they have to pay to do so.. usually the price of an appropriate mooring.. been in force in Salcombe for example for around 10 years.
Stand back as the cheapskates vent..

Re: anchor-outs have significantly harmed the ecosystem

Audubon California Press Release:
Study* documents environmental impacts of Sausalito’s unregulated anchor-outs
Study documents environmental impacts of Sausalito’s unregulated anchor-outs | Audubon California


“Quantification of damage to eelgrass (Zostera marina) beds and evidence-based management strategies for boats anchoring in San Francisco Bay” ~ by Julia J. Kelly et al
“... Our minimum-bounding polygon defined an area of 84.4 ha where anchor-outs were causing damage within the eelgrass bed. This area also comprised the highest concentration of boats within Richardson Bay. The low damage estimate indicated that the area of eelgrass beds with boats was 80.7 ha. Of this area, 25% of the eelgrass bed was apparently damaged by anchor-outs. The high damage estimate indicated that the eelgrass bed was 82.7 ha, of which 41% was damaged by anchor-outs ...”

Proposed solutions (Richardson Bay) include moving the boats, building fixed mooring emplacements, and implementing stricter regulations.

Re: anchor-outs have significantly harmed the ecosystem

This is a common tactic by the wealthy trying to drive out transient boats and extend their land rights out to the adjacent ocean. It's also fairly common with the ultra-conservative conservationists.

anchor-outs have significantly harmed the ecosystem

Humans damage the environment.
Does anyone think an anchor does as much damage as clearing the land and paving it over, constructing a house or Condo and applying chemicals to the yard to kill insects and make the grass look pretty, the run off from the roads with fuel and oil in it?
Marina I stayed in in Panama City Fl, every time it rained you would see the illegal fuel sheen on the water, except it wasn’t from any boat, it was run off from the parking lot.

Anytime you see these kinds of studies, seek the hidden agenda, cause I can assure you there is one.
Anytime any study is funded to find damage, I can assure you damage will be found.
Question that is usually never answered is just how much actual damage is done? How easily does it recover? And sometimes like a wreck for example the damage can actually be beneficial, but that’s not often studied.

Well you could always go on the anchorage on the Pacific side of the Canal where anchored boats often drag as they herd close to the landing stage.. those of us anchored further out never drag.. the bottoms not so chewed up.

I'm pretty certain you're right about there being an agenda, but it's not exactly hidden.
Audubon's declared mission is to restore and conserve natural ecosystems, focusing on birds, other wildlife, and their habitats for the benefit of humanity and the earth's biological diversity. They accomplish this through conservation, advocacy, community involvement, and by tapping into an active network that include more than 50,000 members and 48 affiliated chapters in communities throughout California. Funding this study would be part of those efforts.

This study DID quantify the damage, and I quoted the numbers: 25 - 41% of 80.7 - 82.7 ha

For those who didn't read the study:
“... Our minimum-bounding polygon defined an area of 84.4 ha where anchor-outs were causing damage within the eelgrass bed. This area also comprised the highest concentration of boats within Richardson Bay.
The low damage estimate indicated that the area of eelgrass beds with boats was 80.7 ha. Of this area, 25% of the eelgrass bed was apparently damaged by anchor-outs.
The high damage estimate indicated that the eelgrass bed was 82.7 ha, of which 41% was damaged by anchor-outs ...”

I don't think it likely that scouring the sea-grass would be beneficial (except to those trying to set an anchor).

Re: anchor-outs have significantly harmed the ecosystem

I guess, running aground as opposed to anchoring is LESS enviormentaly dangerous.

Re: anchor-outs have significantly harmed the ecosystem

The the study seems a little bit, I'm not sure what the word is, excessive. They mentioned dredging, but its only the major channels that are dredged and then not that often. For example the Petaluma River has not been dredged since 2003 and is nearly unusable, except at high tide.

From my personal observations there's always been about 200 boats give or take a bit in Richardson Bay, from 2007 till now. I will note that the sea life, and bird life is the most extensive in Richardson Bay. This comparing it to say Treasure Island, China camp, Paradise Cove, etcetera.

Part of the influx to Richardson Bay, was due to the Great Recession. Another reason was Marina changing the minimum length for the liveaboards, from 30 to 35 feet. I know a few people Anchorage in Richardson Bay for those reasons.

As to why there so many boats there. It's the only place in S.F. Bay area that offers dinghy Docks.

By the way, Boats anchored to the west of the channel in Richardson Bay are regulated by the city of Sausalito. It's the boats in the middle to the east of the channel that are sort of unregulated. There are regulations, but there's no money for enforcement or very little money anyway. There's been talk of The Mooring field for 10 years but again there's no money for it.

I don’t know about San Francisco, but Littleton Colorado (Denver suburb) is using single-ply* bathroom tissue as part of an effort to seal cracks that plague road surfaces. Applied with a paint roller, the toilet tissue absorbs the oil from freshly laid tar as it dries, keeping it from sticking to shoes or tires.
* Don’t use two-ply bath tissue. The upper ply doesn’t absorb the oil, and ends up blowing around.

According to their “2014 CDOT Hot Mix Asphalt Crack Sealing and Filling Best Practices Guidelines”, a material may be needed to “reduce or minimize tracking of the sealant by vehicle tires. Common blotting materials include toilet paper, talcum powder, limestone dust, sand, or proprietary, spray-applied detackifiers.”

Re: anchor-outs have significantly harmed the ecosystem

On a related note in the last 15 years more than 10000 Acres of wetland Marsh has been restored. So environmental progress is being done.

The main issue is the high cost of rent in the Bay Area. In the Bay Area a family of four making $130,000 a year is considered poor, mainly due to the crazy high cost of rent and homes.

41% isn’t a percentage of damage, unless you state what the definition of damage is.
That may seem a simplistic statement, but if your agenda is to find damage, then your definition of damage will differ from someone who doesn’t want to find damage.

This kind of thing is a lot like the studies of the effects of smoking, those varied widely, depending on who was funding the studies.

As has been stated, if anchoring is damaging, then dredging must be absolutely catastrophic, best close those ports, cause the damage there is I’m sure thousands of times as bad as our little boat anchors

Indeed a curious study while considering what else is going on in the neighborhood:


Medieval Diseases Are Infecting California’s Homeless
Typhus, tuberculosis, and other illnesses are spreading quickly through camps and shelters.

I quote the passing mention of dredging:
"... For many reasons – including dredging, coastal development, climate change, and aquaculture– California’s invaluable eelgrass beds have declined throughout the state, prompting the California Department of Fish and Wildlife to declare eelgrass a protected habitat, and highly regulate any activity that might threaten it. ..."
