Eelgrass

  1. 1.    Practice proper seamanship.

  2. 2.    If you don’t know what you are doing, or don’t feel confident, ask for help from someone that knows.

  3. 3.    Your groundtackle must be appropriate for your boat.

  4. 4.    Groundtackle must not be caught up in the weeds and eelgrass.

  5. 5.    Danforth-style fluke anchors are the most recommended anchor for the mud and clay of Richardson Bay. High Tensile strength is superior. It will say HT on the side. For instance 40’ boat, 40lb Danforth.

  6. 6.    A 2 anchor system is recommended, 1 from south, one from NW.

  7. 7.    10:1 ratio. 

  8. 8.    5/16” or greater chain, as appropriate for your vessel. Grade BBB, G3, G4, or greater.

  9. 9.    100’ chain minimum per anchor.

  10. 10.  Coming up to a swivel, then 20-30’ heavy chain, and 10’ of at least 1” rope and chafing gear.

  11. 11.  Groundtackle is maintained at a minimum yearly basis, and inspected by a qualified diver, prior to storm season.

  12. 12.  Chafing gear is set up coming off the pendant going to your boat.

  13. 13.  Properly seized shackles.

  14. 14.  All your groundtackle gear in is good condition.

How’s your groundtackle?

Eelgrass meadows beneath the waters of Richardson Bay are presently home to a great diversity of life, micro-invertabrates. They are the nursery grounds for many species of fish, and assists in stabilizing the bay mud and providing a substrate for all sorts of nature’s activities.

The eelgrass meadows in Richardson Bay have grown substantially since records began in ... (reference). But human activity on the water and the effluent discharge from the land do take its toll, and we can do all we can to minimize these impacts.


As an Anchor Out in Richardson Bay, the single most impactful thing you can do to help the eelgrass meadows flourish is to make sure you are not on a single anchor. As your boat swings with the tides a single anchor and chain does in fact drag a very large circle - the radius being your scope - and ploughs away all the eelgrass leaving bare mud.


This creates the what is called the ‘crop circle’ effect




Good Crop Circles

Bad Crop Circles

While it remains unclear what we can do to encourage good crop circles to appear, we do know what we can do to stop bad crop circles from forming.


Its simple: Using a 2 anchor system, with chain on on both legs coming up to a swivel, and a rode, to your bow.

 

It not only is safer, but it happens to be the the Special Anchorage Association’s Anchoring Guidline’s hashed out ad nauseum and forged in the fire of many contradictory assertions and grumbles of various volumes.

You’ve probably heard of Eelgrass if you’ve been listening to any discussion of the Anchorage Community. If you live on the Anchorage you probably don’t even want to hear its name mentioned, Its endangered status is simultaneously used against the community, as grounds for the community’s dissolution, while it is actually so prolific that it makes for a ...


It has grown to its present scope during the many decades that people have been living aboard their vessels in the anchorage,


You might even think that the Anchorage community and Eelgrass are a zero sum game. They are presently cohabiting, and possibly are symbiotic, to date there are few papers studying the impact of anchors on eelgrass beds.
