Default Anchoring in the Ocean

So..I've just purchased this boat, it's a little 12 ft feathercraft (i think?) aluminum boat with a 2 hp 2 stroke engine. It weighs hardly anything..maybe 80 lbs if I had to guess, with the motor.

Anyway, I need help choosing an anchor for it. I took it out in the ocean to fish with a buddy of mine, and I had, I want to say a 10-15 lb mushroom anchor. Admittedly, I didn't know that you were supposed to let out like 3x the boat length in rope, or that you should have chain on it, or anything of that sort.

So..it was dragging a bit, a very slow drift(with the ocean current)..but we only had it connected to a short rope, that probably had about 3ft of clearance from a straight down drop.(it actually got stuck on the floor, and we had to cut the rope..yeesh) I'm wondering what weight anchor I should use, what type, and just how I should rig it up. I'm not going to lie, it sounds a little technical to drop 3-5x the boat length out in rope/chain, because we're sorta targetting specific kelp patties to fish in..but if it's 100% necessary, I guess we'll have to figure out how to navigate that. Any suggestions?

In my humble opinion this boat is way too small to be in the ocean.

What if the water is deeper than 5 times the boat length?

Yeah, definitely noted. We're usually just fishing off shore maybe 100 or so feet, and only on calm days in calm areas. We've got nice little bays over here that stay pretty stable/flat most of the time..but we're definitely aware of the danger. I picked it up for 300, that was about our budget, heh.

Oh, we don't go out far enough for that. I'm using a navionics phone app to try to keep tabs on depth and things. We're not going any further than 18-25 feet of depth. But..I don't know the answer to your question, either, heh. What if? :P

no need for chain or length on a mushroom anchor, really. They are designed to be used for the weight and, if you're lucky, it would bury itself a bit. That said, mushroom anchors belong on a lake or pond.

Get a small Danforth style anchor and a bit of chain with ~3x the length of rope for the depth you are anchoring in. If you need more than 3x depth, then you probably have bigger problems to worry about.

IMHO, Smallest danforth, 5-8 ft of chain, 100' of rode...should be gall you need.(unless it's deeper at the Flemish Cap?) B-)

I'd also second that it's not really an ocean going vessel....more of in the sound or (lazy) river.

In the wrong river, 2 HP means you'll go backwards

Just my .02

Going to make it very easy for you.

1) With a boat that size you won't need much anchor unless you are in steady current. If you are, than anyplace that sells anchors will help you pick one out. There are so many options it's best just to find a local shop and have them help you. You'll want at least 3' of chain, more for more depth.

2) get an empty bleach jug, preferably white. Tie on enough string to hit the bottom, plus about 50% more if in current. Tie on a leader of 200 or so lb mono (for abrasion resistance) and connect to 3-4lb weight (you can make your own out of pipe and concrete if you happen to have some around, or just buy a lead weight).

3) toss the jug in where you want to anchor at. The weight should unwind and hold the jug in place.

4) once the jug settles, drive buy it and notice the angle the line is with the wind/current. Drive directly inline with the line. Go far enough to have 2-3x the depth.

5) reverse or drift back to the jug. If you did it right, you'll be directly over your spot when the line comes tight.

If you have a compass/GPS you can do this without the jug. Just go to your spot, let the boat drift a minute. Find the heading back to your spot. Drive to your spot and continue on the found heading, drop anchor, and you should be on your spot.

You're probably thinking about 3 to 5 times the water depth as far as the scope recommended. When it comes to referring to the length of the boat, that's usually referring to the recommended length of chain to be attached to the anchor.

The common rule is 7X water depth NOT boat length. An you'll probably need a different anchor + chain especially if you're running in an area with tides. Check with locals what works best for the particular bottoms in your area.

Are you guys saying he shouldn't just toss the anchor over the side akin to his hot air balloon?

HOLY CHIT, guys! It's only a 12' boat.
First, if you had to cut your anchor rope cause you couldn't retrieve it, your anchor wasn't dragging.

Second, on a boat that size, an 6-8# mushroom is more than enough unless you have a screaming current. Chain is optional but would help in a moderate current. Danforth anchor OK too.

Any kinda unexpected boat wake or boats not paying attention to you and you will be in the water with an upside down boat. Any wrong move with that light of a boat and in the water you go.

Just not a smart idea.

This is a troll, but anyways, I use this for my Zodiac. About 100ft. No chain necessary.

3x depth not 3x boat length! Of you are anchoring in 20ft of water let out 60 feet of line.

The actual ratio for Danforth type anchors is 7' of line for every f00t of dept for maximum holding power. More if its windy. It's in the Danforth website and also on the label attached to the real Danforth Anchors. You can expect a real Danforth to grab sooner and more firmly than a knock off because the flukes are different from knock offs. After owning three knockoffs and drifting around I decided to buy the real thing and have not regretted it. A 5# real Danforth Hi Tensile holds a 23' boat in winds up to 30 mph. The only reason for the 4' of chain required is to prevent the line from chafing on a rock and busting the boat loose.

That would be 140' of line for 20' depth.

I have an aluminum 14' boat with a 20hp Nissan I trailer everywhere. It's been around Key West and up to 10 miles offshore to the reefs. Also been to Catalina Island in it a couple o times. Thats about 30 miles offshore. I use a 4# knock off with the al boat.

Perfect for rocky bottoms. I always wonder, how do you untangle it from a rock?
I've never anchored in rocky bottoms.
