9. Anchoring & the Windlass
Dropping the Anchor:
Preparation:
•Establish a non-verbal communication system for signaling between the helmsman at the
stern and the fore-deck grunt at the bow, necessary because the noise of wind and the engine
will likely make verbal communication difficult and frustrating. Agree upon hand signals to
indicate direction-to-go, slowing down, putting engine in neutral, stopping the boat, anchor
in the water and clear of the water (to gauge risk of anchor swinging into bow), and anchor
free of the bottom.
•Tie the dinghy painter close to the boat at the bow or amidships to avoid wrapping the line
around the propeller and losing the use of your engine!
Location:
•Consider: bottom composition, depth, swing room, shelter from wind and waves, lee shores
(being blown onto shore), tide (and its effects on depth), current, and rights of the
anchorage (first boat there sets the standard)
•Choose a clear area to anchor, ideally in 12-15 feet, with plenty of swing room.
•Make sure not to anchor on a lee shore. Ensure the nearby land mass is protecting you from
the elements and that you are not being pushed onto the shore. A lee shore is the most
dangerous place to anchor your yacht.
Actions:
•Manually lift the anchor over the bow roller and feed out the chain so the anchor is just
above the water’s surface (but not in risk of swinging into the bow).
•Use the elements – approach from downwind or down current, whichever prevails.
•Once the yacht has bled off its forward momentum, use the electric windlass to drop the
anchor. Pay out chain as the elements push you back away from the anchor, but do not drop
all your chain in a pile or it will tangle and bind.
•Use minimum scope of 5:1 (chain to water depth). In heavy weather, you may want to
increase your scope, always ensuring that your swing area is clear of any obstacles.
•Engage engine astern (reverse), slowly building up to 1500 rpm to drive your hook in. Use
200 rpm increments and take transits*
•Once set, put the engine in neutral and watch your transit sight – the boat should move
forward noticeably. It is always advisable to snorkel the anchor to ensure it is bedded
correctly.
at each setting to ensure you’re not dragging before
increasing rpms to next increment.
Attaching the Snubbing Line:
•Once you have set your anchor you must attach the snubbing line. The snubbing line
protects the windlass and improves the anchor’s holding ability, so it is important that you
attach the snubber every time you set the anchor.
•Attach the hook around the chain link (the hook is too big to go through the link) and cleat
off the bitter end of the line to a bow cleat. Pay out enough chain so that the snubbing line is
taut, holding the full weight of the boat, and the chain bellies slack. If the hook falls off the
chain, it means there is not enough slack: reattach the hook then let out chain once again
until the snubbing line is taut.
Setting a Secondary Anchor:
•If a secondary anchor is required, for instance when concerned about wind shifts and swing
room, deploy the primary anchor as above and ready the secondary at the bow. Drive the
