The many Testings... Since the first idea of this unique concept.
After the initial testing, we were convinced that we have developed a technically very strong anchor.  Many computer calculated prototypes have been made to reach optimum regarding strength, look, handling and performances under all types of weather and seabed conditions.  The result: a true "What A GRIP-Anchor"!

The Test Graphics shows typical characteristics in different seabed.  
The graphics also shows how fast the "STEALTH" Anchor (model used was 1013, 13 kg, from 1991) penetrates for a secure hold.  The length of scope used was 5:1 with all chain.  The tests were automatically stopped when reaching a tension of 30mv, which equals 3000 Kg. or  6600 Lbs.  See Illustrated Techniques # 15 & 16.
In Sandy bottom:
The anchor quickly gets into the GRIP position (#3).  It then penetrates the bottom with the bill and the flukes.  Quickly turning to the  horizontally perfectly balanced position.  When the top fluke is embedded as well the compression effect starts generating a massive holding power.  Releasing the anchor from sandy bottoms is always easy.  See Ill Tech. # 15.
In Soft bottom:  (Clay, Mud)
The graphic show clearly how the anchor generates more holding power the deeper it penetrates the sea-bed.  When on the bottom pay out 5 - 6 times of scope and let wind and waves take the boat, drifting, to a hold.  The anchor will work itself deep into the seabed as wind forces increase.  Power set the anchor carefully.  See Ill. Tech. # 24.

On hard bottoms:  (Rock)
The anchor gets quick into the GRIP position on hard rough and rocky bottoms and the arrow shaped flukes continuously steer the extended pointy bill to soon catch an edge or cleft for a secure hold (#4). 
There are NO bending forces involved due to the centered forces and symmetrical structure.  The release of the anchor is easy.  See Ill. Tech. # 21.
Pulled quickly to a set.  The hold increases the deeper the penetrates from higher forces and although the bottom slightly gives away, soon a massive hold is developed.
The holding forces increases smoothly to a secure hold, after penetrating through the lose bottom into deeper and firmer material.  Breaking the anchor out is easy!
This graphic shows clearly the 100% firm hold after catching an edge or cleft in the rock.  A chain was used otherwise the curve would not be that steep.

In Seaweed: 
With the HANS Anchor the best way is to
let the anchor go with a free fall including chain and mooring line at the same time to the bottom.  It falls with the shank first penetrating deep into the soft bottom underneath the seaweed.  The pointed bill thereby already underneath the seaweed roots.  Pay immediately out 5 - 6 times of scope and then let wind and waves take the boat, drifting, to a hold.  The anchor will work itself into the seabed, to a secure hold, as wind forces increase.  The graphic shows the same as in "Soft bottom" above.  When power setting anchors, do it carefully not to break the bottom.  See Ill; Tech. #26.

Let Go into Seaweed bottom!
1 - Landing on the Seabed
2 - Moved into pull direction
3 - GRIP Position in Soft Bottom.
4 - GRIP Position in Rocks

An anchor must be your best friend to trust in any situation.
