The Mantus Anchor

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.

EASY TO STORE The Mantus 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 breaks down for easy storage, so you can store one or two as spares without taking up much needed 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 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)
  • Sharp-headed nose is precision machined to achieve the perfect chisel shape to achieve maximum penetrating power.

LIFE TIME WARRANTY Mantus Anchors offers a lifetime warranty on its anchors *see Warranty section for details.

Metric Sizing Guide (click to enlarge)

Imperial Sizing Guide (click to enlarge)

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 we 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 worse case scenario, a poor holding bottom and thus may seem conservative but we believe are accurate.

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 (40 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 we divided in three categories: Lunch Anchor category is recommended for lighter use, expected winds under 25 knots, working anchor for winds under 40 knots and finally, storm anchor recommendations are intended for winds up to 60 knots. These recommendations are made assuming the worse case scenario, a poor holding bottom and thus may seem conservative but we believe are accurate.
