The paper examines the definition and concept of Electronic navigation (e-navigation), Electronic Chart Systems (ECS) and Electronic Chart and Display Information System (ECDIS); research STCW convention’s Manila Amendments requirements about seaman education for operation with ECDIS and develop evaluation algorithm for electronic chart systems on STCW convention’s base; also provides examples of evaluations and compare positive and negative aspects as for officially realized ECDIS, as for new e-navigation systems designed in project "EfficienSea 2". In addition, the paper provides evaluation algorithms’ testing methods and implementation process for all types’ electronic chart navigation systems. Paper is intended to familiarize wide range of specialists with positive and negative sides for last developed ECDIS, ECS and e-navigation systems and demonstrate subsequent possible ways of development for those systems.
