Now imagine not adding bow height and anchoring and setting scope for 10' but also forgetting to add a 12' Maine tide.... Seen it a few times, often not pretty when the wind blows...

That 70' of scope you thought had you at 7:1 now needs to be 182' for 7:1 and you're now really at 2.7:1 scope when the tide comes in. Less than 3:1 is a long way from the 7:1 you thought you had..

It would be even worse if you initially set for 5:1..

10' @ 5:1 = 50' (forgetting g bow and tide height)

26' to bow chock at high tide = 1.9:1 scope from what you thought was 5:1....

Watched a guy on a remote Maine island lift his anchor right out of the bottom and his boat just drifted away. As the water got deeper his anchor was not even touching the bottom. I tried to save it in my dinghy but did not have the power into the wind. Luckily a lobsterman came along and we towed it back. My guess is he set for 2:1 at MLW then went for a hike on the island and never accounted for the bow height or the 12' tide that day.....

I tried ordering an anchor online and the SAILNET special brings up an error. I then sent a PM here and an email to them with no response. Today I tried calling and I get VM.

Re: Let's talk about anchors some more

Dear Sailnet members, we are in the process of moving our website to a new hosting service and are experiencing problems with the shopping cart at the moment. If you are having difficulty with the check out process please email me at gregkutsen@mantusanchors.com and I will send the anchor your way first and we will worry about the money later.

Re: Let's talk about anchors some more

Hello Sailnet

Just wanted to post a quick endorsement of Mantus Anchors.
I have a 44 foot Voyage Catamaran, it had a 55lb Delta. I am a charter boat Captain current'y doing charters in the galveston Bay area but am heading to the Virgin Islands this fall. The Delta worked ok, but I wanted an anchor that I would not have to think about. While catering to a boat full of guests the last thing I want to worry about is whether my anchor is going to drag in the middle of the night. On my prior boat I had a Manson Supreme which worked great, I was planning on buying one of them until I came across the Mantus at a local boat show. I decided to get the 85lb, I wanted to sleep well. I had problems getting this anchor to fit on my bow roller, after some discussions with Mantus we traded it for the smaller 65lb anchor. This fits perfectly.
I first used the anchor this past Labor Day weekend. The first night there was little wind and figured we would not have a problem dragging, what stood out in my mind was that when we backed down to set the anchor it hooked up so well that it almost jerked one of the guys off the boat. The bottom in Galveston Bay is mud, thick mud, usually when the anchor is pulled up it is completely covered, the Mantus shed most of this mud.
The second and third night were spend at another anchorage, lots more wind and we actually had a 180 wind shift and then a shift back to the original direction over a few hours. I happened to be on the boat while this happened and we never were anywhere close to pulling the anchor loose. I did watch a few other boats drag.
Although I haven't used the Mantus all that much yet I am please with my purchase, it took a lot of convincing to not go with a Manson Supreme but I am happy that I did.
If you have any questions you can contact me directly.

Re: Let's talk about anchors some more

I have a question about anchors in general. Is it possible to have an anchor that's TOO big?

What I'm thinking of is this: The old Bruce anchor site, when they still made recreational anchors, recommended a 20 kilo (44Lb) Bruce as a storm anchor for my boat.

If I decided to use say a 50 kilo (110 LB) Bruce for a semi-permanent mooring, would it even set properly? Would my boat create enough drag to even bury it properly or do anchors need to be in a range of weights to work properly with a given boat's displacement, windage, engine power for reverse pull when setting and so forth?

I'm just using Bruce for illustration - the question applies to anchors in general.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: Let's talk about anchors some more

I suppose, if you can't power back against a huge anchor and drag it to bury the flukes, the wind isn't going to cause you to drag either. That seems unlikely, however.

But, of course, an anchor can be too large. Put a cruise ship anchor on a J-24 and you will sink it at the dock.

Re: Let's talk about anchors some more

Minne,

Most permant anchors are mushroom types for a reason. Yeah one has to dig them in per say, but once dug in they hold in ALL directions. If I were to use a bruce per say, it would probably be 3 or 4 in some type of pyramid style setup, as they were initially designed this way on Oil rigs. IE and anchor or two/three per side of the rig.

Again, it seems to come down to proper size/wt etc along with what the design of the anchor is, vs "just" wt!

Re: Let's talk about anchors some more

Btl,

Yup, I get it. I was suggesting that it was unlikely you would carry an anchor so large that you could drag it with the motor regardless of whether the flukes were set.

Consider your time worth spend. I`ve been a MM and have cruised the Keys and worked while my boat (home) was on the hook, peace of mind is important.

Two comments.

There is an ancient chinese proverb that goes "The nail that sticks out the farthest get hits first" -apply that however and to whomever you see fit.

...and the other one that I`ve read from someone in this forum somewheres said that he`s never heard of an a guy (gal) dragging from using a too big of an anchor.

I`m comfortable with my 35# CQR with 75m of 3/8th 100m of 1/2" and 35#Bruce with 25m of 3/8th with 100m 1/2 on the bow and a 16#Danforth with 15mm of 3/8th with 100m 1/2" off the stern. My 29ft. 8 tonn gaff rigged cutter is engineless with a windless.
