DIGS LIKE NO OTHER - The Mantus Anchor is designed to penetrate dense, grassy bottoms and set with unparalleled holding power. When tested, our anchors set faster and deeper than any other tested anchor, including Rocna, Manson Supreme, Bulwagga, Fortress, Bruce, CQR and Danforth anchors.
Inclusive Adventures is a Mantus Dealer with experience. We switched to a Mantus M1 Anchor on Possibilities II and an M2 on Possibilities 1 after two dragging incidents.
As a nonprofit, when you purchase from us, 100% of proceeds support providing Inclusive Adventures experiences that produce a shift in PERSPECTIVE from vulnerable to capable with participants and the community.
Ships from Houston TX USA. Under <150lb ships Ground. Orders over >150lb ships FedEx Freight typically $205 to $300.
EASY TO STORE The Mantus Marine anchor lineup 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 needing to take up much boat space.
BUILT STRONG
- 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. Bolt Details.
- Stainless Steel anchors feature a 2205 Duplex shank and 316L stainless steel fluke. The surface is hardened by shot-peening and are then electro-polished to provide maximum corrosion resistance.
- In the carbon steel version, every part of the anchor system is hot-dip galvanized for corrosion protection. (All shanks are HT ASTM 514 Steel and flukes are mild steel A36 equivalent)
- The sharp-headed nose is precision machined to achieve the perfect chisel shape to achieve maximum penetrating power.
Generally, our recommendation is to go with the M1 unless it does not fit. Especially muddy bottoms in rivers, lakes, US Intercoastal, etc
M2 is DESIGNED TO FIT boats with bow sprits and bow pulpits that the M1 with a longer shank and rollbar simply won't fit.
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 and holds better in really soft, silty, muddy bottoms. M1 Hoop acts like a scoop in the mud, improving holding power.
- M1 hoop might help prevent chain fouling by wrapping in circles around the shank if the shank tip or ears are not embedded in a harder bottom.
- M2 has a shorter shank and eliminating the rollbar provides a better fit for boats with bow pulpits with slotted anchor housing and bow sprits.
- M2 anchor is less likely to get plugged up with muddy weeds without the need for the roll bar

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 of potential holding capability. Our anchor sizing recommendations are presented in the table below and divided into 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.
