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 horizontial pull conditions without dragging
or resulting in diabling structural deformation.
*Rope recommendations are based on 25% of breaking strength.
Rope must be in good condition.
