NCHORING
Proper anchoring requires knowledge of RODE and
SCOPE. Read this section carefully, understanding
the relationship between rode, scope and anchor
performance.
The rode is the line connecting the anchor to the
boat. The scope is technically defined as the ratio
of the rode length to the vertical distance from the
bow to the sea floor.

Scope =
Bow Height + Water Depth
Since you want to know how much rode to use
when anchoring, the formula is:
Rode Length = (Bow Height + Water Depth) x Scope
• Scope depends on the type of anchor, bottom,
tide, wind and sea conditions.
• Minimum is 5:1 for calm conditions; norm is 7:1;
severe conditions may require 10:1.
Example:
Rode Length = (3 feet + 10 feet) x 7*
Rode Length = 13 feet x 7*
Rode Length = 91 feet
* Scope factor may range from 5 to 10 or
more. Less than 5, the anchor breaks out
too easily.
