Just use 100 ft of garden hose. It's guaranteed to catch on anything and everything and is almost impossible to break loose

Re: Anchor weight for 1650 Ib boat...

Given your stated anchoring parameters, I would suggest the venerable Danforth 8-S.
I used one for the only anchor on our prior boat, a 4000# 26 footer, for ten years of summer cruising. We anchor in a sand/mud combo. It Never failed us.
Equally important is the chain. For a general "rule of thumb" go with a chain length equal to your boat length.

With a nylon three-strand rode, you should be OK. Since our '81 model boat did not have an anchor locker, the whole anchor setup lived in a sturdy mesh bag that we kept in a cockpit locker and carried forward for anchoring - not fun, but it worked for us.
There are probably quite a few "correct" answers to your inquiry... pick the one that meets the graphical intersection of confidence and acceptable inconvenience.

FWIW, on our prior boat, a 1550# Ranger 20, we used a similar size anchor setup, but did not anchor out often enough to really "test" it.

Our current boat is a 11K# 34 footer that uses a Danforth 13H. Same area and bottom compostion. Never dragged in over 15 summers. We have had to occasionally power it out (!) the morning we departed, though, from under an est. two feet of bury!

As a longtime Chesapeake sailor that cruised thousands of miles in a 1400-pound catamaran....

* Don't get the Bruce. Unless dramatically oversize it will just drag in many coves with deep mud.

* Do get a 10 pound Danforth. Should hold through anything.

* Deltas are good, better than the Bruce in mud, but must be considerably heavier than the Danforth. About 16 pounds for you.

Manson is very good, but perhaps too pricy for your budget. Best choise, perhaps.

* Do get a second smaller Danforth-type. Always good to have 2. This will only need ~ 6 feet of chain.

An 11 lb claw, 9 lb fast set with 20-30' of 1/4" chain would probably hold your boat just fine thru 40-50 mph winds generally speaking. Altho since you are in mud, one size larger might be better so you have more surface to hold you. As in mud, that is usually the key over weight. Hence why some like the fortress over a steel danforth.

I do not like danforths, I seem to have a hard time setting them. Once I do, the do ok until a tide or wind shift sends me a 180. Then over half the time the anchor does not reset. Hence why I personally prefer something like a claw, spade or equal style newer design setup, they more than likely will reset.

I have used a 9lb fstset in up to 15knot winds with 6' of 3/8bbb chain on my 30OA 6500 lbs sailboat, it sets and does fine. My 7.5KG/16.5lb genuine Bruce has held me just fine in winds to the mid 20's. I have about 20' of 1/4" chain on that setup. Rope is 5/8 vs 7/16 for the fastset. Both serve a purpose, ie lighter is min needed per race rules to throw out, heavier is the prefered if anchoring out, sleeping etc. It is below, other is on the bow.

Re: Anchor weight for 1650 Ib boat...

I have a 7 pound-ish danforth now that I plan to keep as a backup/stern anchor. It fits OK in one of my rear lockers but as noted above, they can (and I think so) be a pain to store, move to the bow etc.

My sister made me a beautiful bow pulpit/anchor roller out of solid teak, installation the current project. I tend to put the pull of the anchor on the bow eye vs the platform so the wood platform will only be used to store and launch the anchor.

I originally designed the pulpit to hold a bruce/claw style so I that's why I was most interested in them. I think I am kinda committed at this point. ; )

I also trailer my boat to areas with sandy bottoms, rock, grass etc so I want a good general purpose anchor. Potomac and lower Chesapeake is just primary area.

OH YES one of the things not said in the rain ,at 2.00 am ,when a 40knt squall hits is

" I think I need a smaller anchor and less chain. "
Bigger is always better, never heard otherwise from folks about anchoring. I think I'll pony up and get the larger size.

Re: Anchor weight for 1650 Ib boat...

Danforth type anchors seem to get a bad rap around here, but in mud bottoms like Chesapeake Bay and Long Island Sound, they work well. Main problem is they do not reset reliably in a windshift. I cruised for 30 years on Long Island Sound with just a pair of Danforths and had few problems. My current second anchor is a Fortress and I like it.

Re: Anchor weight for 1650 Ib boat...

The Danforth-type anchors have been king in the Chesapeake Bay and its tributaries for over 50 years. They still are, IMHO.

I'd go for a Fortress anchor. Very light, very strong, and perfect for the lower Potomac area. The 4lb Fortress is rated for boats to 27' or so and can be had for under $100. But, I'd probably go for the 7lb Fortress which gives you a LOT of safety factor for anything you're likely to encounter.

Check out prices on eBay, e.g., Fortress Anchor FX7 | eBay

Re: Anchor weight for 1650 Ib boat...

Since danforths fold flat I think they are easier to store but in any case he has a roller so that takes care of that. If danforths grab they can hold quite well but the problem is a) they can be hard to set, and related b) they don't reset well by themselves. Any type of hard bottom and they tend to just slide across. If you want less expensive, I'd go plow or bruce, best holding in lots of different conditions, go mantus/rocna. At least my .02c.

And yeah, I had to anchor in a marina which had bad protection from the wind with about 40 feet to spare all around me (if that) and I slept pretty horribly waking up every 10 minutes to make sure I wasn't dragging. For what it was worth I never did and had a little more faith in the anchor after that.
