Abstract
The pull force a tugboat can exact when tied to an immovable pie bollard is termed the bollard pull, this is the maximum pull force she is designed to exact on her towing work. This force depends on the size dimensions, hull shape and design of her propulsion machinery. This work is a correlation analysis between the main dimension variables and bollard pull is carried out to obtain useful formulas for the design of future tug boats basing on optimum bollard pull. This analysis is based on a collation of world existing tug boat parameters shown in the paper. An appraisal example computation is also presented to show the method and validity of the derived formulas
