Fortress Anchor使用条件まとめ

Boat Length 28'-32'ftに対するFX-11の使用条件のまとめ
風速15m以下の湾内で水深8m以下の場合
9㎜three-strand nylon rope
6㎜chain2m(水深8m増す毎に2m追加)
Shackle Size6㎜
5:1scope
サンドや通常の軟らかさのマッドの海底では32度の角度で使用


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.
