Haul-out

Haul-out process:  
Haul-out with the travel-lift, generally, a travel lift which is a metal frame and sling the lift belts. It is mounted on wheels, the lift moves into position and the belt lowered under the yacht-hull. The yacht is hanging over the belts and lifted out of the water, and moved onto the cradle in a trailer. For the safe, the yacht should be carefully distributed the load between two belts to avoid from damages.
There are two approach methods, either bow first or stern first (Haulout and relaunch guide, n.d). Before approaching to the travel lift, the lift drive should know which approaching. It is important to the travel lift driver because its lifting belts vary and set up properly with each method. Also, the lift driver should know the lifting position of the boat. The lifting positions are determined by the skipper who indicates the direction, the lifting belt should move to ensure it is correctly placed by the lift driver (Haulout and relaunch guide, n.d).
For the bow-first approaching, the yacht slowly enter in the centre of the pen (Haulout guide, n.d,). The travel lift driver will slowly bring belts. Yacht’s engine should keep running with neutral gear and the skipper also stays in the helm until the engine turned down, advised by lift driver (Haulout and relaunch guide, n.d). The yacht will be gently held by the forward belt until the aft belt has been placed. The lift driver will adjust with necessary.
For the stern-first approaching, the yacht should enter stern first in the centre of the pen (Haulout guide, n.d). Before entry, the backstay of the yacht may be removed. The lifting aft position will be on the lifting point with first belt. The lift driver, then, placed the second belt at the forward lifting position.
The lifted yacht move on to the bilge cradle which is proper for the above waterline repair. As Fig 1, the cradle is ready on the haulage trailer, if the workshop is far from the ramp.

The yacht placed on the proper cradle, the position could be adjusted with the height of cradle bars as shown in Fig 2.

The yacht should be secured on the cradle then move to the factory for repairing as shown in Fig 3.

Re-launching
For the re-launching the yacht, it should move to the ramp with haulage trailer. The process is the reverse way to the haul-out processes. When the yacht has been returned to the water the engine will start. The yacht can move advised by lift driver, the lifting belt should be lowered below than the keel and rudder.

  1. It is usual for the boat to enter the travelift bow first, if the travelift operator decides the lift will be better suited to enter stern first it is he (the travelift operator) who will make that call In other words the boat captain is informed which way to approach the travelift
