According to the last edition of SOLAS the use of ECDIS by vessels becomes obligatory

ECDIS provides an opportunity of use of the hydrometeorological information as additional information (transparent) layers of an electronic chart

It is easier for navigators to have all kind of information in one place (ECDIS) so that other inputs (Fax, pictures, telex, etc.) become not necessary
