Temporary Hoisting
Correct Hoisting
If the boat ever needs to be hoisted, special attention should
be given to the following recommendations:
• Hoist the boat using a horizontal lifting bar only.
• Never attempt to lift the boat by means of a cable sling from
bow to stern lifting eyes.
• Hoist operator should slowly and smoothly lift the boat
without jerking to avoid damage to the lifting eyes.
Incorrect Hoisting
DO NOT use the ski pylon to hoist the boat.
Incorrect hoisting may invalidate the warranty on the
boat.
— 7
Use only a proper sized sling in the designated lifting rings
to hoist the boat.
NOTE: For boat houses, we highly recommend the use of a
lifting cradle. Cradle bunk design should mimic the bunk
design of the trailer.
