| 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. |
