Guardian Anchors
Benefiting from years of Fortress Anchor Research and Development, Guardian
offers excellent quality, performance and economy. Guardian is made from the
same high tensile, corrosion resistant aluminum magnesium alloy and
manufacturing precision as Fortress.
The use of slightly smaller extrusion profiles and the elimination of some of
Fortress’ extra features, such as anodizing, adjustable fluke angles, and
several machining steps has resulted in a very affordable alternative to those
heavy, rust-prone steel anchors.

Anchor Selection & Specifications Guide |
|
Boat size
recommendations are for boats of average windage and proportions in 30
knots of wind, average bottom conditions, and moderate protection from
open seas. Remember that the loads in 42 knots of wind are twice as much
as in 30 knots.
Use
three-strand nylon rope, 6-12 ft (2-4 m) of chain and a minimum of 5:1
scope. Also, a minimum of 6 ft (2 m) of chain should be used for every
25 ft (8 m) of water depth. For storm conditions use an anchor one or
two sizes larger. |

NOTE: Hard
sand holding power figures above represent loads actually achieved on
production FORTRESS and Guardian anchors under controlled horizontal
pull conditions without dragging or resulting in disabling structural
deformation.
** Rope
recommendations are based on 25% of breaking strength. Rope must be in
good condition.
