Re: Anchoring Wind against Tide Conditions

Well as a member of the International Bucketeers Squadron, I would say this is an excellent place to use a bucket as a Drogue. Takes no time to set and generally would have only a minimal effect (just enough to move the boat and keep the chain taut).

No or inadequate bucket? how about a pot or something like that?

Re: Anchoring Wind against Tide Conditions

I agree with Dockhead here: anchor and let boat find its most comfortable position. Any thing else is asking for trouble by complicating a simple process.
Ok, anchoring by the stern can have its benefits but in a strong tidal stream or frisky wind conditions you have a recipe for problems that wil not be easily solved once they begin. Like what? Like when the stern anchor drags !/2 boat length and now your boat is sideways to the tidal stream; the forces on the keel will be so huge that both anchors will be driven deep into the sea bottom and prove very difficult to retrieve . I have had to "cut" a stern anchor loose in this very scenario,and if you have a full keel these forces are magnified even more. So now you are in a jam the boat is heeling unnaturally and your anchor lines will be stretched taut like a rubber band.Good luck even getting you'd rode off the cleat and watch you fingers as now your remaining rode smokes out into these now turbulent waters. So now whatca gonna do? Most windlasses will not be up to the task of getting your bow anchor up now. Well lets do what we always do when in a jam and start the motor and power your way out on trouble ,right?
................................Wrong!............ ................................................

Well in order to get out of this pickle one or both anchor lines will need to be slackened right?
.................................wrong again!............................................ ................

Now your prop has just picked up one of your rodes ( most likely) our stern anchor line and now you are anchored in a strong current by the prop! It gets worse.

......................................Now you have no motor...............................

.........................................And its O' dark thirty..................................

Of course your dingy is ready to go and you are a strong swimmer so that when you dive over board with you razor sharp knife clenched in your teeth you 'll
be able to swim back to your craft as it rockets away from you as the prop is cut free.
Of course this is no reason to panic, you have already thought this all though and know you cannot swim well while holding that knife so you have tied a lanyard around that knife so when you let it go it will drop harmlessly drop below you in the water and there is nothing to worry about as you swim after retreating craft.
..................................still wrong!............................................ .........
The knife planes between your legs as you swim and your strongest stroke involves the ironically named scissor kick.

My friends,you cannot make this stuff up.I had a steel sailboat when younger which saved my bacon from the myriad unnecessary snafus I put her through in the interest of perfecting the science (and art) of anchor deployment. I'm an a lot older and somewhat wiser now and still anchor regularly in the strongly reversing currents of NYC with its heavily fouled bottom ( think railway cars or Jimmy Hoffa) and have so far had no major issues with at the single anchor system.
In case you are wondering its a Manson Supreme 25# with chain and nylon rode while cruising. This years cruise I tried the Roverhi suggestion of using the slot with good results, but the chain can make an alarming bang wnen it reverses in the slot.

Now regarding anchoring by the stern in any kind of a blow , this too is fraught with problems. As soon as the companion way is opened, the weather will enter the cabin and soak everything below and what happens if stern anchor drags and one starts dragging through other boats with no way to maneuver? I wrote on a related thread of witnessing a fine Bristol sloop run aground on a sandy beach in Block Island while dragging a lobster pot on the prop in rather benign conditions where the guys waded ashore in shallow water as the waves filled the cockpit , then flooded below
and the boat ended a total loss.
So be warned ,but some here may learn from others and some will just have to pee on the electric fence and find out for themselves.
.................................................. ...............Love you all..........mike

Re: Anchoring Wind against Tide Conditions

Try an Anchor Spring Line (forward quarter spring).

Re: Anchoring Wind against Tide Conditions

I read Gord May's post on the spring lines to point you into the swell. Great stuff, this will help a lot when in the bays with lighter tidal currents (<2kts) but rougher conditions off the wind.

MROHR's post was enlightening but I do not think it is appropriate to anchor from the stern in any strong tidal currents. With only a stern anchor I would think the situation is even worse when the tide changes and now the wind and current are from the same direction as I don't think she would lay stern into the wind with tide strong. We have anchored in some rivers and bays here with 5kt tides of over 15 feet.

Our boat will hang in the current even with opposing winds over 25kts. As she sails over the anchor in the strong winds, she breaks free and the wind will push all 36 tonnes of her against the current into the closest disaster waiting. Thank god for the local Indonesian fisherman who helped us out of that situation.

So is a "running moor" as Nigel1 helpfully identified the best solution in these conditions???

What about an anchor that resets quickly without your assistance?

Re: Anchoring Wind against Tide Conditions

Lots of good stuff here. I've never rigged a spring on my anchor, but it is a great idea if conditions allow.

The bucket idea is also worth trying.

Many times I've done this dance, but it has never caused me any problems - yet.

Will try some of these ideas next time I'm not pointed the way I want to be.....
