Anchor - bow roller - MacGregor 26M

[kurz]

Chain is 6mm, line I guess 12mm, could be 10mm?

Okay, I'll admit I've never heard of a "Luke" anchor. At least not a pure bred Luke anchor. I've seen similar kedge anchors, but apparently, these Lukes are popular in some places.

Google showed me this video. Interesting.

An old Luke Fluke!
Haven’t seen one of those for awhile!
A classic look in various parts of New England Coastal harbors back in the day. Most were up on shore and off to the side of boat houses… not hanging on boats. I recall when asking the various lobster boat owners why the general response was because they weren’t just all that good. Curious I asked further and the responses varied from not gripping on the rock boulders bottom, jamming in the rock boulder bottom, to plowing through sand, to weed fouling. Most said that it was an inherited item that was.

Most of the ships had Danforth style anchors which they said had superior holding in a variety of sea bottoms. Some also had a modification for a shackle and ride at the head pivot of their Danforth style anchors. They explained that this aided in retrieval of the anchor in boulder field sea bottom. The way it works is when the anchor won’t release when hauling up the primary chain or ride one could pull up on this secondary line to lift the head pivot free.

I’ve tried this myself and it really does work!

The Luke is kind of a Keys specific anchor. I've drug a bruce, bunch of times, rocna, spade, danforth, delta, barnacle, northhill, and none of them were small either. the Lukes design means a heavy anchor which still fits on the boat. So over yanking out anchors during bad squalls at 2 AM. I wont say i never drug that Luke, but it doesnt go far. even on hardpan coral bottoms.

Interesting. That's kind of the gist I got from the video above. The pure "Luke" is a specific use anchor (not to be confused with a Kedge anchor). From what I can tell, it's popular in the Bahamas (and Keys, naturally).

At 50 pounds, it's a heavy beast, but if it allows good sleep, it's worth the effort.

When it comes to sailing the Florida Keys, there is nothing like local expertise like that of Ix.

Hi All!

While we are digressing into odd anchors … The Bulwagga!


There appears to be a growing popularity of this anchor in the full time sailing community for its quick setting and holding capability… but darned if I can see how one would store it without having a large dedicated ‘hatbox’….

It’s similar to an anchor I ran across up on Lake Champlain (not to be confused with Bulwagga Bay on Lake Champlain ) several years ago but I believe that particular anchor didn’t have a pivoting center shank rod whereas the currently available Bulwagga does…. Maybe it was just an early version?

I’d think a long extension bow roller could possibly mount such an anchor.
It would make an interesting (intimidating?) piece on the bow.. at the very least a conversation starter!

PS: Here is a chart from SV Panope on what commercial boat in the Pacific Northwest tend to utilize just for info

Speaking of unusual anchors, the BOX Anchor is interesting. Apparently, the designer let the patent expire. Stephen (Catigail) from this forum was going to start manufacturing/marketing these things. I haven't heard from him in while and don't know if it ever took off. Seems everyone is making them now.

The Box Anchor gets high praise and can collapse.

Storage of anchors big enough to hold our boats seems to be a big issue. The anchor locker is not big enough to hold an adequately sized anchor. I keep my Bruce off the (BWY) roller. A smaller "lunch hook" Danforth style in the locker.

I saw that there is even a triangle anchor

This is the B.O.A.T.U.S. Review of the Box Anchor.

“Box anchor
With its shape-derived name, the box anchor is a square unit with eight angled flukes (four per side, two each at front and back) providing holding power by maximizing surface area contact with the bottom. Once deployed, the anchor's scoop design allows the narrow panels to set cookie cutter-like into muddy bottoms.

Pros:

Popular with pontoon owners, it requires no chain, sets quickly, retrieves easily, folds flat for storage
Easier to use than many other anchor styles when deployed. Harder to handle and stow onboard
Cons:

Not good for long-term anchoring. When anchoring in areas subject to strong current, high wind, or waves, it can tip forward releasing the back "teeth," reducing holding power.”

Big ship anchoring process


Not quite how it works for smaller vessels or combi chain/rope rodes but a nice sorta simple explantation of the catenary effect.
The real anchoring for large vessels is the inertia loading and frictional sea bottom characteristics of the considerable lengths of heavy (think Adult Blue Whale) chain utilized. It’s why so many commercial vessels can still utilize simpler older anchor designs (like the Forjford) as those anchors aren’t the primary position holding means.

Smaller vessels with significantly smaller chain loads and/or combi chain/rope rodes are much more dependent primarily upon the grip of their anchors with the chain weight (think large suitcase) being the “motivator” for getting the anchor shank to lie parallel to the sea bottom and thus positioning the anchor flukes to penetrate the sea bed.
