Photos of Anchors Setting

That's a great setup and a clever way to get photos in cold water. I'm wondering, does the wifi propagate through water? If so you could watch your anchor setting (or not) on your cell phone.

Thanks Mike, I do use the "GoPro app" to verify that the camera is oriented correctly before dropping anchor. Unfortunately, the WiFi signal does not transmit through more than about 3 inches of water.

Malbert: Your idea of hauling the camera down after the anchor has been set is good because it eliminates a very real chance of damaging or losing the camera: With my system of sending the camera down during the set, the possibility exists that the camera could get fouled on sunken debris or rock.

However your "after the fact" method would not get any of those great action scenes during the setting of the anchor.

Here is another anchor setting Video. This time I used the quite short scope of 2.8 to 1. The anchor sets very well initially, but when subjected to my simulated wind/current reversal "torture test", the anchor un-sets and drags.

great video

What a great thread.

Panope, do you you think the buoyancy of your float camera had any effect on the anchor resetting on the short scope breakout?

I do not think the float is large enough to make a noticeable difference. Here is another shot of the camera and float.

Sorted. It had me stumped for a while, as for some reason the embedding was not seen in the preview after editing the post. Only when the post was submitted.

In the end I think the only problem was a missing square bracket "]" after url at the beginning.

I have fixed the embedding for the second video you posted as well. Keep these fantastic videos coming Steve.

Is it wrong to tie a Mermaid to the roll bar?

Oh, I totally misjudged the size. Thanks.

Unfortunately, a third video that I made was shot with the camera not aiming properly. It only shows part of the anchor.

Next time out I will try and get some footage of my Forfjord (big stockless type) in action. I have only used it a couple times and it behaves completely differently than the Manson. Should make for some interesting footage as it takes a bit of distance (dragging) before it sets.

I noticed that it takes me about 8 or 9 minutes to complete an anchor set video. Your mermaid might be a bit short on lung capacity. Then again, with your powered windlass you might shave a few minutes off that time............

Good point. Here in chesapeake I wonder if I'll see anything. I certainly wouldn't see anything while the anchor is setting, I can be sure of that given the muck. I was thinking for chesapeake to set the anchor, wait 5 min for "dust" to settle, then film to confirm the set.

That sure is some hot anchoring action. Maybe next, you can paint it white and try a set in a deep, hard black sand bottom?

Your Mermaid may have some problems with that. In fact, I'm betting you are in big trouble!

Steve, what sort of slope did the bottom have during the second short scope video? It just seems weird that the anchor set fine on short scope first, then failed during the 180 deg direction shift. If the bottom sloped away slightly, then the effective scope angle would be quite different for each direction?

Ben, the bottom is quite flat in that area. It might slope a foot or two for every 100 feet of horizontal distance. Also, the setting direction (and the reciprocal) were about 45 degrees to the slope so the "effective" scope difference between the two directions would be pretty small. That said, the pull that resulted in the anchor un-setting was in the downhill direction.

Perhaps the next time out I will try a couple sets at the even more difficult scope of 2.5 to 1 and see what happens. I think there is as much to be learned by studying a failure as there is a from a success.

Even minor slopes such as 2 feet per 100 are not to be underestimated.

Setting @ 2.8 :1 uphill in a seabed sloping 1:50 the effective slope becomes 2.96 :1

Setting @ 2.8 :1 downhill, the effective slope becomes 2.66 :1

Particularly at short scopes where the anchor is struggling, this can make quite a difference.

One thing that continually surprises me when diving down to seabed level is how much local variation there is in small patches. You would think a sandy bottom would just fill in with wave action and even out. Not so. The effective scope may well be locally helped or hindered even in a seemingly even terrain.
