What is your Bigness Factor?

[s/vPainkiller]

66 lb anchor / 41 foot boat = 1.60

Of course my anchor is a Lewmar Bruce, so that probably invalidates my vote...

1.32, which I believe is two sizes larger than anchor manufacture recommendation (Manson supreme).

Hey, not trying to poke the lion but bruces rock! Just need big ones

[Cotemar]

500 lbs / 36 feet = 13.88

[s/v Jedi]

Pathetic these numbers of y'all except for Cotemars mooring

176lb. / 64' = 2.75

[Target9000]

60/32 = 1.875

Not too shabby.

There is another flaw in this metric, it doesn't account for the new generation anchors. By only looking at weight vs. LOA, you might as well just have an engine block down there. New generation anchors don't derive their strength from weight but from design.

No judgments are being made about the quality of your anchor, just its size. Anchor companies size their anchors by weight vs. length in their charts.

Sure, but it's not a linear relationship. They do their own calculation. Thus a 50 foot boat requires more than twice the anchor that a 25 foot boat does -- which would seem blindingly obvious.

since we are measuring our anchors?


1.29 here....35 pound manson on 27 foot boat

[sailorboy1]

1.38, now I feel inadequate

maybe we should also now refer to this as the
"fear factor"

[boatsail]

should state what kind of anchor it is so we know if it is a dragger or a new generation that holds the boat opc orn:


really though....great thread!

[Tim R.]

Primary anchor 1.125
Storm anchor 1.625

Yes, but anchor companies make size recommendations based on their designs.

For a 30 foot boat, here are a couple of the size recommendations:

• Manson Supreme - 15-25 lbs - BIB 0.8
• Manson Racer - 7.5 - 7.9 lbs - BIB 0.25
• Manson Plough - 30-35 lbs - BIB 1.0
• Lewmar Delta - 14 -20 lbs - BIB 0.47
• Lewmar Claw (Bruce style) - 16.5 - 22 lbs - BIB 0.55

This metric just simply doesn't work. A properly sized anchor has a BIB ranging from 0.25 to 1.0.

Sorry man, sometimes you just can't over simplify things with numbers.

Yes, but Don. You can count your davits or stern ladder to make all the girls smile again
