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.
Temporary Hoisting
DO NOT use the ski pylon to hoist the boat.
Incorrect hoisting may invalidate the warranty on the boat.
Incorrect Hoisting
Use only a proper sized sling in the designated lifting
rings to hoist the boat.
Correct Hoisting
NOTE:
For boat houses, we highly recommend the use of a
lifting cradle. Cradle bunk design should mimic the
bunk design of the trailer.
