But Gregory, a 30 lb. danforth will hold a boat perfectly well. It
depends on the anchorage and the weather and water.

We have used a 30 lb Danforth as a day anchor in some pretty severe
conditions. With enough scope and a good bottom it holds our 70,000
pound trawler just fine (30 kt winds, exposed anchorage with 3 to 5 ft
seas).



LOL! There's a man confident in his luck!

Myself, I'd rather rely on using an anchor that is appropriate for the
heft and windage of the vessel. For a 70,000 pound trawler, a 45-pounder
would be the absolute minimum. Even so, I'd be sure to use two of them
Bahamian-style so I could feel secure through most any normal weather.

Interesting. Wrong, but interesting.

The Mont, later renamed several times and last named the Seawise
Giant, claimed to be the largest ship to ever sail the seas, had a
gross weight of 825,614 tons and used a 86 ton anchor. i.e. the ship
was 22,937.7 times the weight of the anchor.

The Trawler you describe is 1,555.5 times the weight of the anchor
that you mention.

Or perhaps a better way to describe it is the trawler gross weight to
anchor ratio is far higher then that of what is said to have been the
largest ship in the world.

Using your criteria of gross weight to anchor weight the trawler
should be using an anchor of 3.05 pounds.

Or, to put it another way... you have proven, yet again, that you
don't know what you are talking about.


Tell me, please, do you set an anchor alarm on your GPS?

I bet you do? If so, then that pretty much negates your feigned
confidence in your undersized day anchor. And, besides, a
so-called day anchor is a rude operation. You said yourself that
you put out lots of length (scope). If the water is 20 feet deep
that means you put out at least 7:1 scope or close to 150
feet. That means you swing a very large circle and might get
too close to those who use a larger anchor and more conservative
scope. Unless it's all chain, that also means possible chaffing
snagging and abrasion on coral heads and sharp rocks.

And you stink-potters wonder why we sailing seaman don't want
much of anything to do with you?

I wonder why?
