Hello All,

Not looking to stir the pot or get opinions on "best" anchor just looking to compile some data for my own decision making process. It would be much appreciated if you could please supply the following data. Mine is as follows:

Boat Make/model: 1995 Ocean Alexander 456+3
Boat Length: 48'
Est. Gross cruising weight: 50,000+
Anchor make/type: Original Bruce
Anchor weight: 44 lbs
Amount of chain rode: All chain (250'??)

Click to expand...

Boat Length: 42'
Est. Gross cruising weight: 30,000+
Anchor make/type: SuperMAX (pivoting) - Primary
Anchor weight: ~50 lbs
Amount of chain rode: 25' (+ 300' 8-plait rope)

Boat Length: 42'
Est. Gross cruising weight: 30,000+
Anchor make/type: Fortress FX37 - Secondary
Anchor weight: ~21 lbs
Amount of chain rode: 6' (+ 250' 3-strand rope)

How does that help?

FWIW, our most common cruising grounds usually present a mud, often soft mud, sometimes soupy ooze mud... so our anchors and rodes are optimized (I hope) for that.

Also, we only have one electric windlass, so that influences the weight of the secondary anchor. In fact, even the weight of the primary anchor is partially limited by my decision to not use an anchor I can't lift manually (should the windlass crap out).

Maerin is 43 ft. waterline
is 52,000 lbs in the slings with half fuel and water.
About another 4,0000 lb. full tanks
Anchor is 40kg Rocna, 400 ft 1/2" BBB chain
The Rocna was the best money ever spent on the boat.

Wow, 1/2", that is a lot of chain weight! Your anchor is secondary

Boat is 44,000 lbs “empty.” I went up two sizes over recommendation to a Manson 80 lb, figuring full fuel and water alone would increase the weight by almost 10,000 lbs.

300’ of 3/8” G4 chain.

Ok. You guys have me worried.

40’ Flybridge with full canvas, 29,000 lbs

Using a Delta 35 with 250’ of 5/16 chain.

Would love get an Ultra 45 - not in the cards right now.

66000lbs when fully loaded, high windage flybridge OA: #8 Super Sarca + 320' 3/8" chain. Always good

Nomad Willy said:

Interesting,
But anchor load is usually a product of windage.

Wind age is the variable, yes. I suppose tide and current are more predictable?

and sometimes the worst, surge.

Grand Banks 32, rated at 18,000 pounds but about 20,000 actually.
Just upgraded to Sarca Excel #5, 45 pounds.
150' of 5/16 chain, plus 100' of rope rode.
Haven't gotten the new anchor wet yet!

Boat somewhere over 50,000 depending on load.
300' chain backed by 100' nylon attached to a 40kg Rocna Vulcan.

I like it.

Cruising weight - 120,000 lbs
Anchor - Ultra 80kg/Swivel
Chain - 500' of 3/8"

Fingers crossed!

I had a Danforth anchor that supposedly was plenty big for the boat but found it difficult to set in the river when the bottom was river rock (smooth rocks) and near impossible to set when over a river bottom full of grasses.


I went to an 88lb Delta Fast Set plow anchor. Sets first time, every time.

Originally the boat came with an 88 lb Bruce but it dragged a few times in a blow. Never had an issue once I updated to the Mantus.

Hi Lynn !
As a famous sailor/ motorboater 4 revs round the world (2.5 in sailboat, 1,5 in motorboat)once sad: ”when poeple start laugh at you in the harbor becuse of your big anchor, you are very close”
He ment you can never get to big.
I have 40 kg Delta on my Mainship 400 here in Scandinavia and I’m happy about it.
Good luck !

Boat - 30foot, 14000 lbs
36 lb Marsh stockless type anchor.
100 feet 5/16" chain; 200 feet line.

The boat originally came with a 30 pound CQR, but it wasn't designed for weedy limestone bottoms. I may use it if I ever anchor in mud.

As you can see they don’t have a wide fluke so they wouldn’t do well in soft mud. They still hold well in sand around here as the limestone is often just below.

Mine is bigger than yours



Sorry it was too much of a temptation

Fear not. It will do you well, yer bugger...

Sorry, reading the Dark Tower (finally) and the lingo gets ta yah.

I have a boat that on the slings weighs 11 tonne = 11,000kg = 24,000lbs, and a Super Sarca of 22kg = 45lbs, and it is literally a drop and forget type anchor. I feel a bit lonely actually. Anyone else got a Super Sarca..?
