Anchoring Operation
To anchor, turn bow into the wind or current and put
the engines in neutral. When the boat comes to a stop,
lower the anchor from the bow (see Figure 3.30.1).
Proper anchoring requires knowledge of rode and
scope and understanding the relationship between
rode, scope and anchor performance.
Rode: The rode is the line connecting the anchor to
the boat. Nylon line is ideal because it is light, strong
and stretches, it also can be stored wet and is easy
to handle. Add a length of chain between the anchor
and the nylon line to help set the anchor more easily.
Scope: The scope is technically defined as the ratio
of rode length to the vertical distance from the bow
to the sea floor. Scope also depends on the type of
anchor, tides, winds, sea conditions and type of sea
floor the anchor is in. To determine how much rode
to use when anchoring, use this common formula:
Rode length = (bow water depth) × scope
The minimum is 5:1 for calm conditions; normal is
7:1, and severe conditions may require 10:1.
Example:
Rode length = (3 feet + 10 feet) × 7
*
Rode length = 13 feet × 7*
Rode length = 91 feet
* Scope may range from 5 to 10 or more. However,
less than 5, the anchor will break out too easily.
Considerations
• Wind and sea conditions can affect the boat.
• Because the boat is not moving through the
water, there is no control.
• Be sure that the anchor will hold under all
circumstances if you are leaving the boat.
• Understand the principles of rode and scope
and their effect on anchor performance.
SWAMPING HAZARD - Anchor from the bow if
using one anchor. A small current can make a
stern-anchored boat unsteady. A heavy current
can drag a stern anchored boat underwater.
COLLISION HAZARD - Anchor only in areas
where the boat will not disrupt other boats. Do
not anchor in a channel or tie up to navigational
aids as it is both dangerous and illegal.

WARNING
NOTICE
Before using the anchor be sure the anchor line
is securely attached to the eye in the bottom
of the anchor locker and to the anchor itself.
Be careful trailing lines do not foul the .
!
CAUTION
To avoid property damage, engage gypsy lock
and ensure anchor is secured with lanyard
before getting underway.
!
CAUTION

drifting (not under power) at night or in low
visibility.
Keep hands, feet, hair and loose clothing clear of
moving parts (anchor, rode, etc.). Entanglement
