Buy an Quickline Ultra anchor instead. No fussing with the silly roll bar, and it works better. Check it out.

I had to build a completly new bow sprit to accommadate the roll bar. For us the roll bar needed to be in front of the head stay. Ours is a little larger at 25kg and it's like 19" wide and a 13" tall and then the shank is 9" wide, the plow another 20" Thats a ton of surface area. Not something you want hanging out in the breeze. I think they need to be tucked up pretty well. In hindsight, the roll bar is a pain.

Re: Fitting of a Rocna anchor

If you get a Chinese one you won't have a problem.

You should pretty much be able to bend the metal with your hands to make it fit.

Re: Fitting of a Rocna anchor

Weld a standard bow roller on so the roll bar will not hit the bow.
The Rocna will be much better than the Bruce.

Re: Fitting of a Rocna anchor

I don't want to look like a salesman for the Ultra Anchor. But having used the Rocna successfully for two years up until it was recalled and the money paid was refunded in full by West Marine (many thanks to West Marine), I would never consider modifying our boat to accommodate and anchor when so many better choices are now available. We've been using the Ultra anchor just as successfully as the former Rocna and found the pricing within the Med to be about the same as what we'd need to pay for a Rocna.... and again, no roll bar to deal with. And as an added bonus... it looks nicer in stainless steel.

Re: Fitting of a Rocna anchor

The roll bar is the issue and primarily with bowsprits. Typically a bowsprit has the anchor roller surrounded by platform that the roll bar catches and stops the anchor from full retrieval. If there is nothing from the roller axle outboard that will catch on the bar, it should work fine. Switched from a CQR to a Manson without a problem with my Lewmar anchor roller.

The Ultra is a fine anchor but EXPENSIVE. Last time I checked, could buy four Manson Supremes for the price of one Ultra.

I'm afraid that you're being given some ill-conceived advice here. Many of the folks advising you on this thread have no idea that the Malo 39 brings its anchor up through the stem itself rather than via a deck-mounted roller or a bowsprit.

Because of the downward angle of your anchor slot, it's conceivable that a Rocna anchor's roll bar might fit, but I doubt that it would be ideal for your boat. A bigger question for me would be whether the elongated tip of the Rocna anchor would hit your stem before the anchor is fully seated in the roller.

If I recall correctly, the Malo's anchor system was built specifically to fit Bruce anchors, and it does so snugly. There isn't much room for divergence from the Bruce dimmensions. If this is the case, you may find it difficult to deploy anchors other than a Bruce, especially if they have a longer, more pointed tip. Some of the anchors being recommended here have exactly such a design.

I would suggest you contact Rocna directly, and ask whether other Malo yachts have ever been able to use their anchors with the standard setup.

Someone did post a picture of the bow with the Bruce sticking out.

Re: Fitting of a Rocna anchor

Agree with Bash doubt any of modern spade type anchors would fit. See if you can barrow an Al. spade and try it out.

Re: Fitting of a Rocna anchor

I replaced the original Bruce by a 20 kg Rocna on my Malo 37 and the fit is perfect.

Rocna is by far the best anchor I have owned.

Re: Fitting of a Rocna anchor

I used my Rocna for the first time last weekend and was pretty amazed.

Re: Fitting of a Rocna anchor

I understand that the Malo bow roller will be different, but just as a comparison point, I've just bought a 25kg Rocna. I will have to weld 2 extension plates either side of my current bow roller, that will extend forward and down (about 5 cm). These will form a 'stop' that the anchor can rest against. I will need to machine a new bow roller with a groove to support the central shank. I'm going to try something similar to Dashew's hold down, and have a stainless bar I can pin over the top of my bow roller towards the rear. This will have 2 fingers that will locate the anchor as well.

Currently, I've put the CQR back on because the Rocna was flopping around like a dead fish (wait, dead fish flopping?). I wasn't happy that I could lash it securely enough.

Will send pictures when completed (although trying to find an inox man in Greece is like searching for the proverbial needle.)

Re: Fitting of a Rocna anchor

If you are having trouble fitting a "modern" anchor of the Rocna/Mantus/Spade type, the people at Mantus anchors might have a good solution. I used this on my old boat and it solved the fitting problem way easier than rebuilding the roller and/or bow sprit.

Mantus Anchor Mate

The malo is a unique bird, and I am not sure if this would help there or not...
