REFIT: Replace OLOH's Original Anchor
The importance of a boat’s anchor cannot be overstated.  There are many boaters who do not plan on spending any time at anchor or “on the hook” so the anchor’s crucial role as a piece of safety equipment is often overlooked.  It’s pretty simple…should your boat ever lose power or the ability to safely navigate, your anchor could be the only thing on board that will keep you from drifting into a dangerous or even life-threatening situation.  And obviously, when you intend to anchor out – which is a big part of OLOH’s future adventures – you want to sleep soundly, secure in knowing that the hardware tasked with securing your boat is going to do its job and do it well.  Opinions on anchor sizing and type are wildly varied (if you wanna see some fireworks, search for the topic “best anchor” on any boating forum).  But the common sentiment among most opinions we found in our research was that you should have the biggest anchor your boat can comfortably hold and that your windlass can capably retrieve and deploy (the windlass is the winch that is used to lower and raise your anchor).

One of the items we learned about early in OLOH’s pre-purchase survey process was that the boat’s stainless steel anchor’s shank was bent.  This caused the anchor to sit improperly on its mount on OLOH’s bow.   Plus, we were told by several marine professionals and old salts that at sixty pounds it was undersized for the boat.  So this set us on a long hunt for the proper anchor.  The anchor on board was original equipment to the boat and it is not uncommon for boat builders to undersize the “ground tackle” that is included, even on very expensive new boats and yachts.

The bend is a bit tough to see in pictures but someone did something to this anchor that we still find hard to understand.

After a lot of research and many conversations around the docks at various marinas, we narrowed our hunt down to Mantus and Rocna anchors.  As the anchor’s shank needs to pass through the bow pulpit on OLOH, a Mantus or the standard Rocna wouldn’t work because they each employ a roll bar.  We landed on the Rocna Vulcan which was reputed to have similar holding abilities to the original Rocna without a roll bar.

For sizing, we went with the brand’s recommendation for OLOH’s size and weight.   While the 88 pounder (40 kg) probably would have been sufficient, we just exceeded the size and weight guidelines for it.  This put us at the low end for the 121 pound (55 kg) Vulcan but once we determined it would fit, we took the leap.

Move on over partner. There’s a new anchor in town.

The crated anchor arrived perfectly protected and wrapped like a fine piece of 121 pound jewelry (there is cardboard and a cloth sleeve protecting the anchor under the bubblewrap).  The folks at Rocna in Canada have been an absolute pleasure to deal with and completely stand behind their product.

UPDATE:  In its first year of use, while we haven’t been in any particularly challenging anchoring situations other than very strong current in a few places, we can report that the Vulcan has always set on the first attempt and has never dragged.  We always deploy a minimum scope of 7:1 (all chain).  We look forward to getting it wet a whole lot more in its second year and will continue to report back.

  1. Hi, You are spot on about captains defending their anchor choices. In your research did you come across the Super Max anchor? These anchors are manufactured in the US (Reedville, VA) and come with a life long warranty. We own and manufacture the anchor and I am curious if you know about them. We are a small company with an anchor that is manufactured bold for a strong hold! Ann
    1. Hi Ann - Nice pitch (and great tagline)! We did not come across your product during our research but it's always good to know what's out there for next time or for anyone else who's in the midst of their hunt. We'll do some reading up on it ourselves - thanks.
  2. Nice anchor! I am also impressed with the Vulcan anchor and planning on getting one for my soon to be built 50’ catamaran. The builder equips their boats with a 40kg Rocna as standard, but with reports of resetting failures, I am going to request the 40kg Vulcan. I see it has been a few years since you’ve installed it, I am wondering what you think of your anchor? Have you had any issues or recommendations other than what is mentioned in the Rocna user guide?
    1. Hey Pete - As you know from our article we got the Vulcan vs the standard Rocna primarily because standard would not work with our bow pulpit. While we have not anchored out nearly as much as we had intended when we first purchased the Vulcan, it continue to impress us with its easy set and it has never dragged once. We haven't had any issues and don't have any recommendations beyond what we have written. Please let us know how you make out.
