SkipJack II - Anchoring Instructions
Generally, the minimum scope for secure anchoring is about 5:1. The number 5 in the ratio 5:1 is the ratio of anchor rode (scope), where the number 1 is the water depth plus the tidal shift. The recommended scope depends on the wind and current conditions, but generally ranges from 3:1 for calm conditions and short periods, to 5:1 for rough, windy, or overnight conditions, and up to 7:1 or 10:1.
Example:
35 + 8 (water depth + tidal variation) Χ 3 (scope) =
129 (length of anchor chain)
40 + 10 (water depth + tidal variation) Χ 5 (scope) =
250 (length of anchor chain)
SkipJack II is equipped with an AnchorLift electric windlass
and 250 feet of all-chain rode that is marked with depth flags
every 30 feet. Additionally, the chain has red paint every
10 feet. The last 10 feet of chain before the bitter end is
painted lime-green. Stop paying out the anchor chain once the
lime-green mark appears.
To prevent accidental loss of the anchor and chain, the bitter
end of the chain is secured by a stainless-steel ring that will
not pass through the windlass. The windlass may be operated at
the lower helm or at the bow with the hand-held remote control.

- Check the bottom conditions using a chart. Avoid rocky-bottom anchorages or areas with submerged cables, sunken wrecks, etc.
- Remove the safety pin from the bow roller/anchor.
- Using the windlass control switch, let out some chain and carefully guide the anchor over the bow roller until it is vertical and free to lower.
- Position and stop the boat where you want to drop the anchor.
- Take note of the water depth and tidal state and determine the length of chain necessary for a 3:1 or 5:1 scope.
- Pay out the chain with a 3:1 or 5:1 scope, observing the markers as they pass by.
- Once the anchor hits bottom, place the boat in reverse at idle and pay out more chain so it lies along the bottom until the desired scope is obtained.
- Stop the windlass and place the boat in neutral. Allow the backward momentum of the boat to set the anchor.
- The boat will stop when the anchor grabs tight. The anchor is now set.
- Turn off the engine.
- Visually triangulate your position using nearby landmarks and set an anchor alarm.
- Set the WINDLASS MASTER switch at the lower helm to OFF.
- Install the Anchor Bridle/Snubber.
RETRIEVE ANCHOR:
- WINDLASS MASTER (AT LOWER HELM) ON

-

Anchor Bridle/Snubber
SkipJack II is equipped with an Anchor Bridle/Snubber. The Anchor Bridle/Snubber is used once the anchor has been set and serves two important purposes:
- The bridle relieves all tension from the windlass to prevent mechanical damage.
- The snubber cushions the boat from loads applied to the anchor chain due to heavy wind and waves.
The anchor bridle is a Y-shaped nylon bridle line that has two
braided eyes and a stainless-steel mooring ring. The snubber has
two stainless-steel quick-release shackles, with one on each end.
The two braided eyes of the nylon anchor bridle are attached to
the bow cleat, and the lines are then led through the bow
fairleads. The bridle then hangs below the bow with the
stainless-steel mooring ring a few feet below the bow roller.
One end of the snubber is connected to the bridle ring, and the
other end is connected to the anchor chain.
