Mantus Anchors

Mantus Anchors

The best setting and holding boat anchor you can buy!

Mantus anchors were born out of that desperate feeling of not being 100% sure that your anchor will hold under stronger or variable conditions.

Many sailors have started dragging under load with the anchor not setting properly, breaking free and then dragging and not setting again.

Mantus anchors are designed to dig deeper, and set stronger to give you peace of mind. They are high quality, practical, durable and affordable.

Mantus anchors set fast and deep with tested, reliable holding power and they even break down for easy storage. You simply will not find a higher quality product anywhere.

Prepare for your big next adventure on the waves and buy your anchor and anchor accessories from our online shop!

Anchor Sizing Guide

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.

However, 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 – even 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
  • Storm anchor recommendations are intended for winds above 50 knots.

These recommendations are all made assuming the worst-case scenario, a poor holding bottom and therefore may seem conservative but we believe are accurate.

Assembly Details

Bolts, Washers and Nuts are provided with every Mantus Anchor.

In the event of replacing a lost fastener, please make sure to always use proper size.

Always use locking washers, or nylon lock nuts, and tighten the nut securely.
