Default danforth anchor size recommnedation....?

I have a danforth anchor for my Wellcraft 180 Sportsman. The anchor is about 6-7 pounds. It is fine when water is calm. However last Saturday when it was choppy, wind 20 knots, the boat started dragging it. I live in Miami, so the bottom is sandy.

What size anchor do you recommend so the boat won't be dragged again? Thanks so much and I apologize if the question is too basic.

This isn't meant to be smart@$$, so don't think it is... I don't think a Danforth is a great anchor, but I have a few myself. (I really like the delta-style anchors much better. even considering the price - they're worth it.) That being said, I'd honestly get the biggest Danforth you can afford/manage in your anchor locker. Your anchor will never hold "too well", so a bigger anchor will only be a problem if you can't manage it.

Also, make sure you're using the right amount of chain. Even if your anchor is the right size, it may not get dug in properly if you use too short of a chain. Ask the old salty dogs around here. The chain really does make a difference.

A size 8 danforth with chain should do the job. Maybe 8' chain.

I agree with the above. If you had eneugh chain and rode even a small danforth will hold quite a bit in sand. I bought a 14# plow delta clone for my 24 wa. I like it better than my backup dan. I have a bow pulpit and danforths dont sit as well as plow while under way. Add some chain to your set up and make sure you have at least 5:1 slope on the rode.

Fortress 4lb. Buy once cry once. Amazon. Back it up with
4ft stainless chain and you will be proud to whip it out at the sandbar!

Out holds a 8lb danforth on my 4000lb Baja.

A 9 pounder with 10-15 feet of chain should be fine for that boat. Anchoring is 80% technique. Don't just throw it over, let out some rode and tie it off. Drop it over, back down gently (or let the wind back you down) while letting out rode 7 times the depth. Tug gently to pre-set once it will take a hard tug so you can pull the boat forward manually, cleat it off and set it with reverse power.

I noticed a huge difference when I went to all chain. It makes a huge difference.

Danforth makes several types and qualities of anchors. A 5H has more holding power than the 14S.

H = High Tensile and S = Standard.

The 5H with 20' of ⅜ chain and lots of 7/16 or ½" three strand line should be more than adequate. the larger line is much easier on the hands than say, ⅜ (which would be adequate).

And anchor exactly like caltexflanc said above.

Be careful not to buy cheap Chinese chain. It can disappear in no time at all, and that 5H is a pretty expensive anchor.

ditto on both bigger anchor and more chain. 8' is the absolute minimum for temporarily anchoring. For bad weather or overnight I would want double that.

Your boat is comparable to my former 18 HydraSports. I used a 5 lb Danforth Hi-Tensile (was about $80 at the time) w/6 ft of chain. The line (rode) would fail before that anchor would pull out of sandy bottom. I'm using it on my current boat, since it's rated for a much larger boat. I added another 6 ft of chain as added insurance. Fortress are hard to set if you anchor in moving water, like a tidal river, bc they're so light and don't get to the bottom quickly enough. Your current anchor should be more than adequate if you use 6-8 ft of chain. Anything more is overkill unless you routinely anchor in stormy conditions.

Listen to this. Much more the chain rather than the anchor. A guy on THT taught me a cool trick. Put 8 ft of chain on it for day to day calm fishing use. Have an extra 10' plus of chain with a shackle to attach if it's rough. If that anchor tension stays parallel to the bottom that's the key. Also danforth isn't the best in sand.

Keep in mind the scope too. 3:1-4:1 recommended. I do a bit over a 2:1 if I'm just fishing

We also spent the weekend down in miami and sunday it got real windy in the bay. I used to have problems to set anchor (just to set) but i had only 3 or 4 feet chain. Bought 11 feet stn stl chain and now the trouble is getting the anchor out next day lol. I am using a fortress 11, really good stuff. Buy half the lenght of the boat in chain, it will make a tremendous difference. Good luck.

Bingo: t3rockhall and Cobia 217 are right. First you want a genuine Danforth--not a Danforth type! Second you want the High Test/Tensile Danforth. The Fortress is also a great bet. I anchor regularly with a Fortress FX 7//Guardian 6 with a 22 foot pilot house boat--recently I was in 50 knots plus (enough to blow my inflatable over the top of our boat, over 6 feet above the water) without drawing in sand. The Delta (again, get the real thing) is OK, but the Danforth/Fortress is better in sand or mud. If I drug with the 14# Delta, the #7 Fortress would always hold. I have used the Danforth HT in 12, 22 and 40 lbs sizes on large boats for many years. Look at the fluke construction, the sharp edge, and "T" shape to give stiffness.

Also the 3rd generation anchors are great. I include the Ronca, Manson Boss, and Supreme, as well as the Spade etc. Recently I have been using the 10# Manson Boss, and it works better than the 14# Delta, in all conditions I have used it in (including a full month of anchoring each night recently.

Yes, chain is nice, but with the Fortress you can have good holding with just the rope rode. I always use at least 6' of chain, and for the primary anchor about 25 feet of chain, with 1/2" 8 Plait.
