Section 2 Boat Operation
Gunwale Lifting Eyes
Your boat might be equipped with gunwale lifting eyes.
These gunwale lifting eyes are only available as a
factory-installed option .
Your hull would have a special lamination schedule
and aluminum plate inserts to distribute the lifting load.
If your boat has gunwale lifting eyes that were installed
by the factory, you may use them as attaching points
to lift your boat.
If you use the gunwale lifting eyes to move the boat,
attach a four-point harness that is professionally certi-
fied to a working load of at least 6300 pounds (2858
kg) with a safety factor of five. Your boat might have
been shipped with a Boston Whaler lifting sling set that
meets all manufacturer requirements for lifting this
boat.
To provide a 5° bow-up angle during lifting, the front
two straps are slightly longer than the rear two straps.
The front two straps are marked FORWARD and rear
two straps are marked REAR .
Attach at least two guide lines to control the boat while
it is being lifted.
Move the boat slowly.
!
CAUTION
Lift sling angles must always be greater than
60° from the deck, measured in any direction.
Lift sling angles less than 60° will multiply the
lifting forces and will damage the gunwale
lifting eyes and the boat.
!
DANGER
Never allow anyone to be in the boat or under
the boat while you are lifting it. A mistake in the
lifting procedure or a component failure could
cause serious injury or death.
