The cost of the crane is divided amongst all the boat owners as fairly as possible. Ideally, we should just divide the cost of the crane equally amongst each boat owner.
The cost of the crane is billed by Stratford Cranes by the hour from the time the crane leaves the crane yard to the time it returns to the crane yard. The final bill is paid by the club. Some of the crane time is common to all boat owners. This is the travel time to and from the yard and the time to position the crane to lift the boat. We try to minimize the crane moves because of the time needed to move the crane. The remaining time is the time the crane spends specifically on a single boat.
We time the crane lift to determine how much crane time is spent on a single boat from the time the crane is in position to put the slings on the boat until the time the slings are off the boat. The clock starts if the boat is ready or not.
