anchors... how many? - Wharram Builders and Friends2024-03-29T11:16:21Zhttps://wharrambuilders.ning.com/forum/topics/anchors-how-many?commentId=2195841%3AComment%3A94666&feed=yes&xn_auth=noThree strand rope works out o…tag:wharrambuilders.ning.com,2013-02-23:2195841:Comment:952672013-02-23T00:41:45.538ZAnn and Neville Clementhttps://wharrambuilders.ning.com/profile/AnnandNevilleClement922
<p>Three strand rope works out ok if you have a long "fall" into the rode locker, but on our Wharrams, that is not usually the case. So Nev and I selected multiplait nylon rode to back up our anchor chains. Multiplait resists what is called hockling where the three strand seems destined to do this twisting that gets ever tighter until small knobby knots appear and make the line weaker and more difficult to deploy because of inevitable tangles.

<p>Having never tried a Rocna anchor I may change my mind, but a plough or a bBuce type anchor of maximum manageable weight, including chain, is first choice for a bower anchor. Enough chain to keep the anchor set is as important as the anchor it'self, without carrying unnecessary weight, so three strand rode completes the tackle.......weight of rope happily allows an axess to be carried.

<p>We also use 100 feet of chain every time we anchor and more if there is a blow expected. So do all our long distance cruising friends. Now that we have the 80+ pound anchor we tend to use it alone unless a strong wind shift is expected. Then we put the big guy where we expect the wind to come from and use the 60 pound anchor to hang on until then so we start out like this \ and end up like this / but have gone from the smaller to the larger anchor.

If there is a blow, we get away from all the other boats especially if they are not long distance cruisers because they are more likely to drag. During a blow we keep anchor watch mostly for the other boats and we run up our outboards hourly so they will be warm and ready just in case. Head mounted flashlights are plentiful on Peace IV for just these kinds of nights. Then you have a "storm's over"" celebration on the beach after. We also never allow the nylon to touch the ground. The more chain, the less sailing or "hunting" around at anchor. A weight let down the chain will also reduce the sailing but it is not so much needed on a Wharram as it is on some monohulls. </p> I found the comparison I ment…tag:wharrambuilders.ning.com,2013-02-20:2195841:Comment:951462013-02-20T11:33:58.031ZGalway Bayhttps://wharrambuilders.ning.com/profile/GalwayBay
<p>I found the comparison I mentioned but am having trouble posting a direct link. The article is called Anchors Aweigh in the Gear section at <a href="http://powerandmotoryacht.com" target="_blank">http://powerandmotoryacht.com</a> . What surprised me was how good the results were with only 20ft. of chain and 5:1 scope. This is less chain or scope than I or most of us would be happy with. </p>
<p>I use 15m [50ft] 10mm [3/8]chain and a long scope [uncrowded anchorages].</p>

<p>Yes. In a big blow Peace IV sails at anchor but she does so very slowly and gently so there is no snatch on the set anchor. We have anchored in winds over 60 knots many times in Peace IV. She does not drag with our set up now. WE also have Monson Supreme anchors. Some folks are having a piece of rebar welded to the point of plough anchors to help them cut through heavy grass or crusy anchorages.

Some folks are having a piece of rebar welded to the point of plough anchors to help them cut through heavy grass or crusy anchorages. We have both heavy grass and thick crusts in our favorite anchorage in Bahamas so we tried that and it works fine. It is not costly to have the rebar welded on.

<p>Steve - Lots of good advice here. I am not a liveaboard but in 20 years I have never used a marina either. I did sail a friend's 35ft tri with a 25lb anchor. We often dragged. I started bringing my own anchor out with me !</p>

<p>I have never needed to lie to two anchors we have lots of deep inlets with excellent holding in heavy mud despite the coast itself being very exposed. The old advice was to set your second anchor to anticipate a wind-shift in the second half of a storm. So if S/W veering N/W set the second N of the first so the rodes are 60 / 90 deg to each other. I have never had to do this as so far I always manage to find good shelter.</p>

<p>It all depends how big (heavy) your boat is and where you usually anchor (anchor ground). To save weight (if the boat is light and small) I'd use for 3 anchors max. 20 meters of chain and then 100 meters rope. The main anchor with chain suficiant to the depts and places you usually anchor but with at least 50 meters chain plus rope. </p>

<p>Our boat sits quietly at anchor but that is likely because we usually anchor in rather shallow water and so there us usually all chain down since we have 200 feet of it before we come to the nylon back up rode. I agree that our boats need the same size anchors for similar length of monohulls. Any of our anchors would be rated as properly sized stand alone storm anchors.</p>

I would be happier with two GOOD anchors than four I did not trust ?</p>
<p>I find that in a blow I need at least as good an anchor as a mono. The mono sits quietly in the water pulling steadily on its anchor. My boat wanders and snatches at the anchor much more. I think that in a blow any cat probably does the same. Also if there is any swell the cat "surges" more than a heavy mono. All this can break out the anchor.</p>
<p>Some good news. I came across a comparison test for anchors [you tube] but what was really interesting was that the tests were carried out on rope / chain combo. and this rode set all the anchors and held up to the point where the anchors failed / broke. So confirmation that this works.</p>
