When the boat is hoisted from the water, proper use of the stern
eyes or a sling system is required for all MasterCraft models. Though
stern eyes are designed to lift a boat from the water, care must be
taken to ensure you do not damage your boat. A spreader bar used
at the stern, will help ensure that the load at the stern eyes is vertical.
A strap placed between stern eyes, and then lifted from the mid-point,
is not the recommended method, and will put substantial additional
stress on the stern eye mounting location.
DO NOT use the ski pylon or any portion of any tower
for lifting. ey are NOT designed to be used as a cen-
tral lifting point. Also, DO NOT use the stern ski tow as
a lifting ring. e deck may be damaged. See the Storage
Cradle sub-section of this section. Also never lift a boat
with water in the bilge or containing a water-filled device
such as a ballast system or sack. e extra stress will put
an excessive load on the hull and lifting equipment that
may seriously damage the boat. Such damage may not be
covered by the warranty.
Using Lifting Eyes
An overhead hoist with a minimum two-ton capacity should be used
to lift your boat. Cables should be properly rated for each model.
Each cable should be rated at or above the full weight of the model to
be lifted. When lifting, keep the bow slightly higher than the stern to prevent
any possibility of water running into the engine exhaust manifold.
Using Lifting Slings
An overhead hoist with a minimum two-ton capacity should be used.
Slings must be six (6) inches wide by twenty (20) feet long and each
sling should have a minimum capacity rating that is equivalent to the
weight of the model that is to be lifted. Use an eight-foot spreader
bar on each sling to prevent damaging side pressure to the deck or
gunwale molding.
li fti n g t h e boat
Lifting slings must never contact shafts, struts or hard-
ware protruding from the hull. Damage may result
that would void the warranty.
When the boat is out of the water, it is important to
support the hull correctly to avoid any hull damage.
Such damage may void the warranty.
Storage Cradle
If a storage cradle is used, the hull must be properly supported
to prevent load damage. This can occur with as little as fteen (15)
pounds per square inch of pressure. DO NOT support the boat by
resting the hull on the keel (the central fore-and-aft structural mem-
ber in the bottom of the boat’s hull, extending from the bow to the
stern). Vertical supports must extend from the chine (the angular in-
tersection of the bottom and sides of the boat) to the keel with no
gaps between the hull and cradle supports. A total support area of at
least 250 square inches is required for proper support of boats under
25’ and 500 square inches for boats over 25’. Protect all items extend-
ing from the hull (i.e., the rudder, propeller, ns, etc.) to prevent them
from resting on the cradle or the ground. DO NOT apply any load
stress to the propeller, shaft, rudder, swim platform, water intake grate
or other protruding items.
