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.

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.
