Mantus Anchors

[Toxophilite]

Hello!
!2' Gartside 130
180 lbs
probably 400-450 lbs with me and gear. Over night camping anchor

I have about 6' of chain I can use.

If it is assumed that I will be anchoring appropriately for the location and conditions...

Mantus says their 2.5 dinghy anchor would work fine for overnight boat camping (Mantus site says it is 4lbs though they call it a 2.5lbs anchor )

They have a heavier 8lbs Galvanized one for about $10 more (site says it's 11lbs)

The nice fellow at Mantus said the 2.5 dinghy anchor would be good for boat camping overnighters

What do knowledgable forumites say?

Re: Mantus Anchors

I would go for the 11-lb anchor, definitely. I think a lot of people who do a lot more anchoring out in small boats than I do would say, use the biggest heaviest anchor you can fit onboard. Saving $10 and a few pounds isn't worth it.

Re: Mantus Anchors

Look up Panope anchor tests on YouTube. This guy, on his own dime, not sponsored like most phony anchor tests, put the Mantus 2.5 anchor through some tests with a big, heavy boat and that little anchor excelled.
In fact, I suggest everyone look at his tests. No one else has come close to them.

I've met the guy and he is the real deal. My primary is a Mantus 2.5 and the backup is a Danforth HT 5 lb.

I have learned a ton from Steve and his anchor tests. https://youtu.be/a9Zh-MrmwaA

Re: Mantus Anchors

Autonomous what sort of/size boat are you using..a skerry? Wi-tom Do you have a navigator? or is that your brother's boat or am I confused.. I watched some of your videos I believe.

That's the thing, the mantus 2.5 tests are pretty impressive ,they're light and not too big. Most people use the 8lbs anchors for much bigger boats. Twice as big and many times heavier.
However another part of me thinks, bigger, heavier, better, galvanized, ballast...

I generally think one generally tends to overdue things in little boats rather than the opposite.

Re: Mantus Anchors

those anchors with the loopy things on top get jammed up with kelp. you think the hook is in the bottom but it aint sometimes
got a lotta kelp up here.
tests schmests...they always test in sand
i use a 30 pounder on my 24 ' boat...sometimes it has 30 pounds of vegetation in its mouth on top. like a remora.

I sail a Kurylko Alaska (18' Whitehall-style sail-and-oar boat)--about 250 lbs empty. But I've also used (and posted a lot about) my brother's Phoenix III, a Ross Lillistone design, about 180 lbs empty, maybe.

I don't do much "real" anchoring--often I'm tied to shore, with a tiny seaplane anchor off the transom to hold the boat off the beach/rocks. No kelp, no tides. But my main anchor is a 12 lb. Northill--old school, but cheap.

I do think a light rowboat-type boat like ours doesn't need much holding power compared to a keelboat or heavier boat. But better too much anchor than too little, maybe. It will be interesting if more PNW small boat folks weigh in on this question.

Re: Mantus Anchors

Personally I'd carry both the larger anchor as my main everyday anchor and also the smaller one as a back-up in case I couldn't retrieve the bigger one or I needed to lay out a second one in high winds. I carried two anchors in Fire-Drake, my 18' sail and oar boat - an 11 lb Danforth, and a 1 kg Bruce that I bought when I didn't know any better. In my new boat my larger anchor is a Rocna. I still also carry the Bruce, just in case, figuring that an undersized anchor is better than no anchor at all if you've lost your primary.

Wizbang makes a good point about the prevalence of kelp on our coast but I have found that all three anchor types I have used can bring up a lot of kelp with them after a night spent on the hook in a kelp-filled cove. In those cases, I would hope that the heavier anchor stood a better chance of penetrating through to the bottom. Not being a diver, I have never confirmed that but I sleep better with a larger anchor.

Re: Mantus Anchors

I'd want the length of chain to equal at least my waterline.

Autonomous what sort of/size boat are you using..a skerry?

The poor neglected Skerry just sits inside these days. You know someone that wants to buy one?
I have 17' sail-n-oar with about twice the capacity of the Skerry.

Nope. Panope's anchor tests are in a class by themselves. No one else has come close, ever.
Watch a few and then get back to us.

Re: Mantus Anchors

Is the mantus 2.5 the anchor you use with your 17' boat? What design if I may ask?

Love to have a Skerry, Likely can't afford it. Glued ply Lapstrake?

I think the 2.5 would do all you need it to do. I also think you would never regret going up a size to the 11 pound.
Any dinghy anchor will struggle in kelp. Just doesn’t have the weight.
+1 of Panope anchor testing!

The Skerry is a glued lap CLC kit.
The other boat I referred to is a Gig Harbor Boat Works Salish Voyager.
FWIW my Mantus 2.5 is an early one I bought used. It does not have the clip in rollbar, rather a welded straight rod from ear to ear.

Re: Mantus Anchors

For a glass boat that Salish Adventurer is attractive, looks well thought out stout and practical. ah you have the galvanized dinghy anchor?
The one they said they stopped making 4 years ago?
