Design consideration: do I get to pick my anchoring days? Can I avoid most bad weather through good judgment?
Cruiser - Have to deal so ...
Multiple, diverse kits of:
- The heaviest tackle you can retrieve by hand
- The largest size you can afford & store
- All chain, with a long elastic nylon snubber secured by a trucker hitch
- Ability to lasso tree or boulder as a secondary
- An offset line from rode to midship cleat to keep her nose straight to the waves when the wind wants her to roll
- Sea anchor
Recreational -
You can go lighter, perhaps compensate with insurance and towing coverage

Re: Anchor weight
I have a 28 foot, 13.400 lb boat. I used a 33lb Rocna while riding out hurricane Irene and it held just fine. It was my first experience with winds of that strength and the experience made me appreciate a little more the forces involved. I upped my anchor to a 45lb Manson Supreme and while that big honker might look a little silly on my bowsprit...I feel safe.

Never intended to use two all the time.
I was talking about having two to use conditionally, based on the floor at the anchorage.

Re: Anchor weight
30 foot: 35 lb
44 foot: 60 lb
47 foot: 60 lb
42 foot cat: 45 lb
Deltas and CQR's. Bruces go 2 sizes above book size. Danforth and Fortress book size is good.

For that reason we have chosen to shorten the amount of chain in the ground tackle SYSTEM, simply to reduce cleaning time when we bring the anchor back aboard. Less mud in chain links, less mud on deck... (In other holding ground, we'd add chain.)
As also mentioned, we tend to upsize at least one size from manufacturer's recommendations. Also, size (fluke and stock dimensions) is a factor, not just weight (another reason why the flukes are larger on a Fortress anchor of the same weight as a steel Danforth). This approach only works within reason and -- in heavier weights -- also depends on whether one has an electric windlass or not...

I know that a 44lb Bruce/claw type is very affordable, and I believe I'd go with an all chain rode on that rig.
Thanks

Going with a 44# anchor on your less than 10,000# displacement boat is way way overkill even if the anchor has a poor holding record. Used a 45# CQR on our 20,000# boat for 1 1/2 years of 24/7/365 anchoring and never dragged. Even with a manual windlass, it was no fun retrieving that anchor. Hope that you have a windlass if you go that weight of anchor. Wouldn't count on a young healthy back to aid retrieval as the healthy part might go quickly muscling that much weight.

I should probably mention that I have no windlass at all, and if I went to a heavier anchor with a chain rode I would be looking at adding a windlass.
In that case is still be staying away from electric if I can.
I want as few systems that require power as possible.

I've also priced a 33lb Bruce/claw.
It is 20% less expensive than the 44lb.
That is good news.
I've been reading that heavier is better, but I guess that's only true to a point.

Re: Anchor Weight
25' LWL, 3000 displ: primary 33 pounder with 75' of 8mm chain plus 150' of 1/2' octo poly.
We used 22 pounder in our extensive adventures and it was adequate.

If I were anchoring in the Chesapeake without a windlass, I'd probably go with a Fortress.

Re: Anchor Weight
Pacific Seacraft 34 ~14,000 lbs. I use a 35 CQR (the horror!) and a 33lb Bruce, and have a giant fortress stowed away too. Also a smaller Danforth on the stern. Manual windlass is a bit of a joke, a Simpson lawrence 555 or something like that, but a 35 lb anchor and chain is fine as long as it isn't blowing too much. Singlehanded in a crowded anchorage, with the wind up makes it a chore.
My old Cape Dory ~10,000 lbs, had a 25 lb CQR.
I don't really belong to the upsize crowd, but would if I had a good windlass. I don't think I would go as heavy as some listed here, just too much anchor to have to stow away, and have the fortress for heavy blows in my current cruising grounds.
