*Suggested anchor weight/boat size is limited for use on a good anchoring bottom such as deep and
consistent sand, mud and clay. Boat size recommendations are for boats of average windage and proportions
in 35 knots of wind, average good bottom conditions, and moderate protection from open seas. Note that the
loads in 43 knots of wind are twice as much as in 30 knots.

*XYZ urges mariners, whenever possible, to avoid anchoring in living coral to avoid damaging this important ecosystem.
A boat anchor should NOT BREAKOUT when overpowered if set correctly in good holding ground. It has long been an accepted theory that any boat anchor will eventually breakout if pulled on hard enough, even if set well in good holding ground. In other words: A boat anchor system's weakest link is its holding power. At XYZ, we claim that this theory is not valid! With the Extreme’s huge strong fluke, ultra short strong shank, ability to dig extremely deep, and the ability to correct itself for different angles of pull; The XYZ WILL NOT BREAKOUT if overpowered, but will continue to bury! The Extreme has been repeatedly tested under extreme conditions (up to 1100 HP commercial vessel). When the XYZ was set in deep sand, we were ALWAYS able to break the recommended size rode (often 5/16" chain) WITHOUT the XYZ breaking out or deforming in ANY way! Your XYZ holds! It will not breakout.*
*Assumes that the boat anchor is well set in deep sand. In other, lesser holding bottom conditions, the XYZ will set and hold better than any other anchor of similar weight.
from 0° to -170°
The boat anchor on your boat should be like the brakes on your car, designed for use in the most severe situations! When your life and your boat depend on a boat anchor, there should be no compromises! The XYZ has been tested under EXTREME
loads. 5/16"/8mm chain broke - the XYZ held!
The Design of the Extreme enables 360° rotation. Even when pulled from 170° backwards, the XYZ will rotate horizontally and continue to set deep.

BOAT ANCHOR SHANK
A long shank is easy to bend or even break; a short shank is much stronger. The optimum shank is short, strong, and sharp on both the bottom and top edges. Sharp edges allow the shank to cut through the bottom, not restricting the boat anchor's ability to bury deeply. ALL EXISTING BOAT ANCHORS have long shanks simply because the boat anchor design does not allow them to be shorter.
Ultra short, light, sharp
and strong Shank has almost no penetration resistance.

The Shank is made of 17-4PH mirror polished stainless steel or high strength galvanized steel.
Cutting-Edge Saw Blade
is made of corrosion resistant
stainless steel. 17-4PH is
used by NASA and in the aerospace industry. Very high yield strength (up to 1100-1300 Mpa 160-190 ksi) can be achieved.
Connection between the shank and the fluke
is made with 4 OVERSIZED 18-8 stainless steel machine screws. (1/2”/13mm - on 33lbs/15kg). Each screw is capable of holding 2 (two)
