DIGS LIKE NO OTHER
The Mantus M1 Anchor digs in like no other anchor. It has been designed to penetrate dense, grassy bottoms and set with unparalleled holding power. When tested, Mantus Anchors set faster and deeper than any other tested anchor including; Rocna, Manson Supreme, Bulwagga, Fortress, Bruce, CQR and Danforth anchors.
EASY TO STORE
The Mantus M1 Anchor line up simply has the best boat anchors available, whether you are a long-range cruiser, racing or going out for a day sail. The Mantus quick-set anchor is stowable and breaks down for easy storage, so you can store one or two as spares without taking up much needed boat space.
- Formed out of high-quality steel plate. Contains no cast parts.
- Shank and shank boot are welded from top and bottom.
- Shank and roll bar are bolted to the fluke.
- ASTM certified steel bolts are oversized with a large margin to ensure safety.
- Although the shank is attached to the fluke with 4 bolts, a single bolt has sufficient strength to handle the maximum expected load on the anchor.
- In the carbon steel version every part of the anchor system is hot-dipped galvanised for corrosion protection. (All shanks are HT ASTM 514 steel and flukes are mild steel A36 equivalent)
- Sharp-headed nose is precision machined to achieve the perfect chisel shape to achieve maximum penetrating power.
After the release of the Mantus M2 Model we often get the question: Which one is better?
Both Anchors have an amazing setting and resetting ability and both are excellent choices for a primary anchor, but each has its own small specific advantages.
Both anchors roll over well in most bottom conditions and it is rare for a properly weighted anchor to end up upside down, nevertheless M1 Anchor due to its roll bar is better at rolling over in a really soft silty bottom.
The M2 Anchor is less likely to get plugged up with muddy weeds and, without the need for the roll bar, the M2 is less bulky. Thus the M2 Anchor provides a better fit for boats with bow pulpits with slotted anchor housing and bow sprits.

When making sizing recommendations for a working anchor we are generally referring to the needs of a cruising boat spending most of its time on anchor. In doing so we try to envelope high sustained winds (50 kts) and assume poor holding conditions (low viscosity bottoms). Some may think these recommendations to be too conservative especially when compared to sizing tables from other manufacturers.
Companies often make claims of superior anchor efficiency, stating that their small anchor X will outperform a much heavier anchor from their competitors and often use sizing charts as a marketing tool to that end, recommending anchors and anchor systems that are dangerously undersized for their intended use. Comparing surface area can be a good judge for potential holding capability.
Our anchor sizing recommendations are presented in the table below and divided in three categories: Lunch Anchor category is recommended for lighter use, expected winds under 30 knots, working anchor for winds under 50 knots and finally, storm anchor recommendations are intended for winds above 50 knots. These recommendations are made assuming the worst-case scenario, a poor holding bottom and thus may seem conservative but we believe are accurate.
