Anchoring
Your boat is equipped with a windlass, anchor, rode
and an anchor chute. Stow the anchor in the chute
when not in use.
NOTE: Before using the anchor, be sure the safety
lanyard is removed and the anchor is secured to the
windlass chain.
To anchor, bring the bow into the wind or current and
put the engine(s) in neutral. When the vessel comes
to a stop, lower the anchor from the bow.
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.
Proper anchoring requires knowledge of RODE and
SCOPE and understanding the relationship between
rode, scope and anchor performance.

Rode length = (bow water depth) X Scope
Be careful that the trailing lines do not foul in
the propeller
!
CAUTION
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 prevent abrasion of the line.
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. Since you want to know how much rode
to use when anchoring, use this common formula:
Rode length
= (bow water depth) X Scope
The minimum is 5:1 for calm conditions; normal is
7:1, and severe conditions may require a 10:1.
Example:
Rode length = (3 feet + 10 feet) X 7*
Rode length = 13 feet X 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.
