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
Be careful trailing lines do not foul the propeller.
!
CAUTION
Keep hands, feet, hair and loose clothing clear of
moving parts (anchor, rode, etc.). Entanglement
may cause severe bodily injury.

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.
Anchoring
To anchor, turn bow into the wind or current and put
the engine in neutral. When the boat comes to a stop,
lower the anchor from the bow (see Figure 3.36.1).
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 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
1
Rode length = 13 feet × 7 1
Rode length = 91 feet
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 are leaving the boat. Understand
the principles of rode and scope and their effect on
anchor performance. Because there are a variety of
anchors with different uses, discuss with a Boston
Whaler dealer the right anchor for this vessel.
1 Scope may range from 5 to 10 or more. However,
less than 5, the anchor will break out too easily.
NOTICE
Turn on anchor light when at anchor or drifting
(not under power) at night or in low visibility.

INSTRUCTIONS AND WARRANTY INFORMATION.
To avoid property damage, engage gypsy lock
