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.

Did I not also mention windage? Weight is of less consequence
in smaller private yachts than is windage. So your diatribe has
little actual meaning when it comes to smaller recreational craft
as it's not the weight that breaks them loose but the force of
the wind acting upon their surface area exposed to the wind.

Ah, windage... I can only assume that you somehow believe that a
70,000 pound trawler has more windage then a 1,651,228,000 pound
tanker.

As was previously mentioned, you have proven, yet again, that you
don't know what you are talking about.


Get a clue, dock boy! If you had a BILLION pound ship but
no wind or current you could anchor it with a ten-pound rock
and it would stay put.

And you prove your brilliance yet again. "If you had a BILLION pound
ship but no wind or current". Would you care to elaborate on these
conditions and where one might encounter them..... other in your
fevered dreams.
