We have a brand new website dedicated only to AnchorGuardian.

Bringing Safety To Anchoring

Anchoring is a routine and age-old operation, built on mastery, experience and sensitivity. It is as frequent as mooring or loading and unloading cargo. The anchoring process – from laying to lifting the anchor – is critical for the safety of crew and passengers as well as sealife below. It is a dangerous operation that requires specific skills and continuous attention.

Even when ship’s crew work diligently to lay anchor in the most secure way possible, dragging can happen. Immediately recognizing anchor drag can avoid dangerous collisions and even grounding.

AnchorGuardian offers a new dimension of safety at sea by minimizing the risk of anchor dragging, providing predictions and immediate alarms.

Our disruptive, patented technology offers safety during anchoring by identifying in real-time dangerous anchor drag, independent of GPS and any movement of the ship.

Additionally, AnchorGuardian predicts the anchor hold with early warnings and provides essential information while laying the anchor, while at anchor and when lifting the anchor.

For the first time ever, using sensor fusion and sophisticated algorithms, our technology can build a stable dataset of the anchor’s relative and absolute position providing reliable information over the entire anchoring procedure.

AnchorGuardian offers a entire range of intelligent data while anchoring…when you need it.

Providing Critical Information And Alarms

Laying The Anchor

Our Solution

AnchorGuardian provides high sub-meter accuracy with an early alarm if the anchor is dragging, independent of any movement of the ship.  Thereby false alarms due to factors like wind and tide, where the ship sways around the anchor, are eliminated.  A disruptive, patented technology that will change the way we see and approach the anchoring process. 

Our mission is to ensure that no matter the size of a vessel – whether it be a leisure boat, merchant ship, fishing vessel or super yacht – all information needed whilst anchoring is available to ensure safety for sailor, ship and sea.

Dangers Associated With Anchoring


diagram collision

Collisions disrupt holidays, planned voyages and shipping schedules. They damage boats, sometimes irreparably, and can lead to physical harm. In a nutshell, collisions cause havoc for captains, crew and the immediate surroundings.  


diagram grounding

A dragging anchor can lead to groundings. The consequential losses of grounding can be significant: damage and loss to the vessel, other vessels, property and the environment. Not least of which, groundings have also led to loss of human life.

Oil Spills

Anchor dragging has been reported as the root cause of many oil spills and marine ecosystems suffer the brunt of these accidents long-term. They hamper the water-repelling abilities of bird’s feathers, they destroy the insulating ability of fur-bearing animals and they harm fish, shellfish and sea turtles.

Damaged Cables/Pipelines

Accidents with underwater fiber net cables due to anchor dragging can have repercussions to neighbouring countries or even felt around the world when internet connections are broken. Operators estimate anchor dragging to be the main reason for damage to sub-sea oil and gas pipelines.
