Anchoring
The 210 Montauk is equipped with an anchor storage
compartment located in the bow of the boat. Because
there are a variety of anchors, with a variety of uses,
discuss the types of anchors with your dealer to
find the right anchor for your boat.
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.
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 aid in setting of the anchor.
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:
Bow Height
Water Depth
Rode
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.

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.

WARNING
NOTICE
Before using the anchor be sure the anchor
line is secured to the eye in the bottom of the
anchor locker.
