Steve on SV Panope has done similiar tests with every anchor made. He does a ninety degree swing to see if the anchor will reset easily. I recommend his videos to anyone who is in the market for a new anchor. By the way, the Vulcan scored the highest of any anchor.
This video was originally done for a forum I am a member of so perhaps more explanation is needed here. Most anchors have a minimum recommended scope of 3:1 and hence I used that. Other anchors tested by forum members had about the same. I think the main point is that the anchor never released from the bottom and stayed dug in even in a silty bottom and yes I did apply quite a bit of power. I had 2 x 350hp engines @ 2000 plus rpm so any anchor would move under that force. The Vulcan is a great anchor and has great holding power so you will not be disappointed in it should you decide to purchase one. I do normal let out around 5:1 scope when anchoring but to compare it to the other tests done I only used 3:1. I will try to get some more videos done in nicer sandy bottoms.
great video, but I have a request: if you ever find the will to do this again, could you maybe include a 180 test? this is to say a test whereby you set the anchor normally and then turn around and go the other way until it sets again, just to see how it would behave in an anchorage with changing currents thanks anyway :)
Why only 3:1 scope? no anchor would be expected to hold at a shallow scope with throttle applied. would be interested to see the holding power under proper use. I have been thinking of purchasing a vulcan.
Excellent camera setup there. I wonder if a scope of 7:1 were used there would have been less or even no "ploughing effect" when you gave it 350hp and it would have just buried itself even deeper.
Hi Keith, Sorry I was away and didn't see your message. You made the right choice I think buying the Rocna. I believe the fortress anchors are also very good and I will be buying one as a light weight second/spare anchor. Plenty of tests on here showing the fortress in action but I don't think it is quite as good as the Vulcan. Cheers
Keith have you been pleased? I have owned both. Never had an issue with either although I agree that the danforth style anchors are more likely to be disturbed by a significant change in pull direction and have a slower reset. I have also had my fortress catch huge weed balls and had the flukes jammed at one offset with wedged clams.
Sure. Cruisersforum.com lots of great info and a hell of a lot of video and photos of anchors setting. SV Panope does a lot of these videos and they are great information.
@@ross82 I sold the boat a little while ago but kept the anchor for a while longer in case I bought another boat. I only just recently sold the anchor as well but over the years of use I was very happy with it.
Hello Dave, Thank you for posting this great video! We love to see Rocna owners testing and showcasing their anchors and we are happy to hear your positive feedback. We would like to seek your permission to add your video to the Independent Testing and Reviews section of our website.

Hello Rocna. First thanks Dave for the clarification on my initial question and appreciate the video. I have since purchased a Rocna Vulcan 15 (33lb) and used it on my 33 Tiara in windy northeastern conditions with similar bottom conditions to the video (mixed mud/sand/silt). My only concern now is breaking my windless! Haha. The anchors set so abruptly and solidly that even a gentle drift backward in a moderate breeze snaps my chain to attention upon setting. I have been able to throttle backward once the bridle is attached to my all chain rode at about 5:1 scope with no movement. Any more power and I fear breaking something. Very pleased with your product. I have a marina-mate who also purchased a rocna based on my research and experiences. He is quite impressed as well. Peace of mind has no price. Thank you.

What a 3:1 scope means depends heavily on distance between bow roller and seabed: ua-cam.com/video/FOKVO3JBgDY/v-deo.html
Putting a strain gauge in the line would also be good information. Thanks for the video. Considering this anchor.
1 minute into that video and I was switching to Amazon to buy one. Things badass.

Brilliant idea, your camera rig!

It would be nice to know what 350 hp is equivalent to in Beaufort scale ..... probably force 20 😄
I'm curious, do you know what size the anchor is? Vulcan 15?
Wondering how much power was applied?
I am deciding on either the Vulcan or the Fortress marine anchor. Do you have an unbiased and objective opinion between these two?
Fortress doesn't like to be disturbed, but may provide a bit better holding in some bottoms. I'd go Rocna except for a storm anchor
+Colwell Janacek I ended up buying the Rocna.

+M3hammerdown I ended up with the Rocna 10 but I haven't used it yet.
Thanks very much for extra information. Are you able to share the name of the forum?
Sure. Cruisersforum.com lots of great info and a hell of a lot of video and photos of anchors setting. SV Panope does a lot of these videos and they are great information.
All chain rode?
Yes it was all chain.
What size was the anchor? I this your current anchor on your boat?
It was a 20kg Vulcan anchor and yes it is still the current anchor on my boat.

Hi Rocna Team,
No problem I am happy for you to use the video. I shall endeavour to make some more.
