Ship Lifting
* Tie winch wire rope to the ship hull
* Choose the bow at the bottom of the better position to fill in one or more air bags, when lifting to a certain height, will be the first to reach the ship under the winch tows. Barge bottom flat type, such as airbags and bottom contact area large, if the ship hull weight was small, as long as there is difficulties, from the first feeding can be from one side to the other string into a air bag.
When the hull weight is bigger, according to certain spacing increase 1 to 2 or more airbags, until lift up first. First a "v" shaped powerboat, often because of the airbag and the bottom contact area is too small lifting force is not enough, would require airbag back, sometimes want to back a quarter of the captain to lift up the bow.

* Lifting vessels in conjunction with the lifting gas bag together, playing hard block, good ship, withdraw rubber lifting airbags.
