A movie that fails to move a boat with a crane and falls

A movie that fails trying to move a boat on which people ride from land to water. Whether the balance was destroyed by the weight of man, it dropped considerably fancy, and the person who got into the boat was thrown out by the impact of landing.

Details are as below. The thrower drops to the water luckily. It might have been able to reach the boat with water as long as the balance is kept a little more.

When you move the boat with a crane as usual it is like this. It will be a bit uneasy if the hull becomes oblique, but it is arriving safely.
