The M2 Anchor
DIGS LIKE NO OTHER M2 Mantus Anchor is designed to penetrate dense grassy bottoms and set with unparalleled holding power. Expect the Mantus Anchor to set every time the first time!
EASY TO STORE Whether you are a long range cruiser, racing or going out for a day sail. The Mantus breaks down for easy storage, so you can store one or two as spares without taking up much needed boat space. A single bolts is used for the construction to facilitate easy dissassembly and storage.
BUILT STRONG
- Formed from high quality steel plate and high end precision casting.
- ASTM certified bolts are oversized with a large margin to ensure safety.
- Although the bolt used in the assembly is load bearing, only a fraction of the load is transmitted to the bolt.
- Stainless Steel anchors feature a 2205 Duplex shank and 316L stainless steel fluke. The surface is hardened by shot-peening and then electro-polished to provide maximum corrosion resistance.
- In the carbon steel version every part of the anchor system is hot-dipped galvanized for corrosion protection. (All shanks are HT ASTM 514 Steel and flukes are mild steel A36 equivalent).
- Nose of the anchor is reinforced to guarantee a lifetime longevity.
DESIGNED FOR FIT Designed to fit boats with bow sprits and bow pulpits.
LIFETIME WARRANTY See warranty section below for details.
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 rollbar 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 M2 is less bulky. Thus the M2 model provides a better fit for boats with bow pulpits with slotted anchor housing and bow sprits.

ANCHOR SIZING GUIDE
Use the following guide to determine what size of anchor to use:
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.
