    A small mooring, for example for a 30' boat, will weight about 1200 lb (545 Kg) including the chain. However, to service mooring, they need to be lifted which includes breaking them loose. We often apply tension that is over twice the weight. Sometimes we dive and inject air from a hose around it to break the suction from the mud and silt. At the maximum force the OP suggests, he may only be able to work on moorings for really small boats.
