[Rhodes22-list] anchoring

Peter,

What difference do think the weight of a boat implies for the size of 
the anchor?

I would imagine windage is the factor.

No matter what they weigh, all boats float.

If weight were the factor, the size of a battleship anchor in proportion 
to it's weight would be substantially less than the size anchor most 
people carry on their Rhodes 22s.

Someone recently told me that if you take away wind and current, a 25 lb 
Fortress anchor will hold an aircraft carrier.

I've never tried it, though.

As I've often mentioned, a 2 1/2 lb Fortress Guardian is my go-to 
anchor.  I set it from the stern, and walk it forward.  Once properly 
set, it is extremely difficult to dislodge until you get almost directly 
above it.  There is never enough windage on my boat to deform the 
anchor, part the line, challenge the shackle.

My boat is moored on a 300 lb mushroom anchor as are virtually all of 
the boats in the cove where I keep my boat.  (There are hundreds.)

The cove has been hit by strong winds from time to time, but few move 
from their moorings.  The biggest fear of damage is from other boats 
coming loose, and debris. 

The entire fleet swings on individual anchors.  Anchoring bow and stern 
puts you broadside to the wind with enormous stress on the anchoring 
system if the wind is shifting.  Mushroom anchors are just as strong in 
360 degrees, and you expose your boat to the least stress.

If I had the problem of moving my boat under storm conditions I would 
try to rig up an air bag on a mushroom anchor so I could tow it to the 
place I wanted to set my boat, release the air, and sit on the single 
mushroom.

When your boat is floating freely and always facing the wind there is no 
chafing problem to speak of, and while the wind creates uncomfortable 
creaking in all of the boats, the mechanical stress on the components 
seems negligible.  I put a canvas chafe guard on my bow line where it 
goes over the edge of the boat (no chock).  I have not had to replace 
the chafe guard in 10 years of use. 

Most wind damage around here is done to boats on shore.  The wind 
topples one into the next.  I suspect my boat is far safer in the water 
than it is on land.
