The purpose and scope of this paper is to outline the best practices when determining the ship¿s safe speed and best possible speed for sea voyage legs as per COLREG definition, ship¿s owner and charterer requirements and 3-D model of ship¿s domain. In this paper the author presents the attempt to define the following notions: ¿ship¿s safe speed¿, ¿critical speed¿, ¿limited speed¿, ¿reachable speed¿, ¿economical speed¿ and ¿optimal speed¿. The author also depicts methods that can be used for estimating ship¿s safe speed in the restricted sea areas by means of three-dimensional model of the ship¿s domain.

The purpose and scope of this paper is to outline the best practices regarding the watchkeeping procedures, seafarers' competencies and voyage planning in the restricted sea areas, when piloting the vessel and turning the ship in the narrow channels and sharp bend fairways. The author describes the basic principles concerning the navigational equipment settings, their data reliability and limitations. He presents the method that can be used for the classification of the sea areas and estimating the safety of navigation by means of the turning circle diagram, Wheelhouse Poster, Sea Trials Report, ROT technique, Pivot point knowledge and the author¿s own concept with his new model of the navigational risk assessment. He also describes the factors to consider when determining the ship¿s domain parameters. He explains how to use the ship¿s domain model to estimate the safety of navigation and navigational risk in the restricted sea areas, including the best practices for the passage planning, dead reckoning and position fixing and monitoring. He uses the systematic approach to the ship¿s operation in the aspect of estimating its safety when navigating in the restricted waters.
