Re: Anchoring with changing tides and wind

My link was really meant to be a generic response to the question. (one technique)

Anchoring methods and anchor types/size should be specific to the waters and conditions, So I am happy to defer and refer the OP to those who sail in his waters.

I should note that I took the danforth that came with my boat off the bow and replaced it with a Spade. I stowed the danforth and use it as a spare. I also have a smaller one at the stern that I can deploy quickly in an emergency. ( engine dies in a bad spot)

Re: Anchoring with changing tides and wind

1 - Observe what others have done and do similar
2 - Anchor in areas of similar size boats with similar rode if you can (a boat on all chain will swing quite differently than one on chain/rope)
3 - Be aware of the expected tidal change - both for depth under the boat at low tide, and for adequate scope at high.
4 - As has been said ensure anchor is solidly set - this goes for swinging free, of course, but ESPECIALLY for stern tie situations. Cross winds/current can put very heavy strains on the anchor and rode.

Seconding Jackdale.. never seen a Bahamian anchoring setup here, and one boat anchoring bow and stern can ruin a bay for others that would prefer to swing free.

We stern tie a lot, but actually sleep better swinging free. On a windy night the only way I can relax if stern tied is if the wind is coming off the beach. Otherwise it's either a crosswind, or you're on a very close lee shore. Remember if the anchor lets go then the only thing you're tied to is the beach.. or rocks... and that's where you'll go... Still, it's a common practice for many reasons, and in reality in summer (in our area) for the most part the winds shut off overnight if the weather is fair and settled...

Re: Anchoring with changing tides and wind

Everyone has already covered most things I would suggest, but I'll chime in to reiterate a few things:

- Chain is pretty key in this scenario - you can supplement the chain with a lead weight, or put the two Danforth's in sequence on the rode. We've never tried this, but we've read about it.

- That being said, the only time we ever drug anchor in the PNW was when we used our Danforth. It's not so good at resetting. After that instance we started using our slightly over-sized Bruce and haven't dragged since (it resets quickly and easily in most conditions). We LOVE our Bruce anchor...it's held us in some pretty crazy winds. You should totally buy the Bruce that's being offered for $20 (what a steal!)

- Letting out a lot of scope is also a good idea, if you have enough space. Be conscious of your swinging radius if you have neighbors. If you don't have neighbors, just let it all hang out! Not really...but you can be generous with your scope.

- When you arrive at an anchorage hail your new neighbors on the radio to get their opinion. Let them know that you're new at this and that you would benefit from some friendly advice - most people are awesome about helping newcomers...though it also means they might not sleep soundly knowing they're anchored next to a newbie .

- Set your anchor so that you're facing the same way as everyone else in the anchorage and back down on it (with your motor in reverse until it is set - ie, you're not moving backwards anymore).

- I highly recommend picking up the Daschew's book Practical Seamenship - they have a great section on anchoring strategies.

- One of the biggest challenges we've had with changing wind, tides and current is that even though we stay put through it all, we somehow get wrapped around our rode (or rather, it get's wrapped around us). This happened in San Francisco when we were anchored off of Angel Island and in La Paz (both times we were moving around quite a lot). If that happens there are two strategies we've used: 1) let your rode out quite a bit more and then maneuver your boat to get "unstuck" - sometimes easier said then done (you just have to try it out) or 2) tie your rode to a life-ring and come back for it (this one kind of freaks me out, I have nightmares about losing our beloved Bruce). I'm sure there are other strategies.

Good luck to you! Have fun!

Re: Anchoring with changing tides and wind

Without having a dinghy to aid in setting the stern anchor, you can (first) set the bow anchor. Let out EXTRA rode so you back down over the spot you would take the dinghy out to. (second) drop the stern anchor there, leave a little extra behind the boat and cleat it off. (third) don't use the engine, yet pull or windlass the bow anchor in to the length that sets you where you need to be (meanwhile this should set your stern anchor well in the mud), cleat off the bow rode. I say don't use the engine because you don't want to back into the stern rode and catch your prop, and you don't want to chug forward into the bow rode quicker than someone can pull it out of the water.

Then just find the balance of the two rode lengths.

Use a kellet as I have described above. Since we used one we have not had to experience anchor rode wrap around the boat, keel or prop again.

If you don't the rode may decide to saw through the soft lead keel when you wrap. I have seen it leave quite an indention in a Tartan 34 once when it wrapped the beavertail part of the keel and gashed it pretty well.

Re: Anchoring with changing tides and wind

when in doubt, ask someone who is already anchored where they set their hook and from which direction they set it and what they use , and you will learn fast.....
every anchoring i do is in tidal waters with clocking winds--every direction daily each. isnt hard to make it work. i do it with one genyooowhine bruce 30 kg anchor and using 150-160 ft on ground in 20ft of this changing situation and i have no problem.

isnt hard to learn, and do not forget to ask until you are secure with your method which will change for you until you have it set into your mind.

Re: Anchoring with changing tides and wind

In 10 years of living on the hook the only time I have used the Bahamian anchoring technique is


wait for it


the Bahamas. Specifically off Nassau and in one ot two of the cuts like Farmers. I would always check to see what the other boats around me were doing before setting the two anchors at 180 degrees. If you have significant additional rode on one of the two anchors using the dink is not required.

Finally no thread on anchoring is complete without a mention of the ode to the credit card captains/. Watch for the man coiling the rope and the girl in the green bikini who contribute to the recovery in their own ways.

Classic, classic, classic!

These are what get 'guns on boats' threads started.

Re: Anchoring with changing tides and wind

Awesome. Thanks. Great advice.

I guess because I haven't anchored I imagine the winds coming up super stron like it is now and slamming the boat. But most places I will anchor are pretty protected coves, not like if I were anchored in front of port townsend oday with the wind 30 mod onshore. There was a guy anchored out. Ill see if he's still there.

Re: Anchoring with changing tides and wind

I did practice today bit went well. I backed down on it with the engine and didn't budge. Then I watched for a while while i ate and didn't drag.
