My rule is, if you anchor your boat and it's still in the same place the next morning and if you do this on a regular basis with the same results, your anchor (and rode) are big enough. Skill plays a part as well so if you're in the habit of just dropping the anchor and forgetting about it, you'll need a bigger anchor than if you set it and back down on it.

My anchor is 33 lb. My boat is 28'

24,000 Lb boat (weighed in the slings), 34', 33# Lewmar claw, 120 ft of 5/16 G40 chain, 240 ft of 5/8 Brait rode. This anchor has never let me down in 100+ anchorings per year, 8 years running. (All mud bottom of SF Bay and CA Delta)

It's not so much the size of the prize, it's the angle of the dangle.

in emergency situations, dropping and depending on it can save your boat.

Overnight anchoring is extraordinarily simple if the place and conditions are good...which one csn pick and choose.

If you have to finesse your anchor or use a fancy technique to secure you snugly.... good luck with bad conditions and a main propulsion or steering failure.

Anchoring here usually means 180-degree current changes at several times a day. Always worries me on overnight anchorings (with 2.5-knot currents typical). Nevertheless, the cheap, not oversized, Bruce copy has always held.

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'??)

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).

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.

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