    An ECDIS is a unified navigational information display which presents on an updated chart background,updated route,present position and fast track, combining these as approprite with radar,ARPA and other navigational sensors in order to improve safe navigational through the clear display of the situation in the vicinity of the ship.
    chart can be corrected through a floppy disc,compact disc, even directly through the satellite systems. The latest system of updating charts is that the manufacturer transmit the chart updated as broadcast in coded format. Dedicated software is fitted in the ECDIS which will receive these updates,decode them and correct the charts.

                            Vector charts are more advantageous than raster chart because vector chart enables user to select many alarms, such as depth alarms, various modes such as head up and north up, Zooming facility, Add or remove the data required.

The Squat is mainly experienced over in shallow waters it increases with square of the speed of the ship in order to reduce squat ship speed has to be reduced squat is calculated by the formulae
                                                    squat= V(square)/100*Cb

                                                        The overall decrease in the underkeel clearance fwd. and aft is called squat.

                                                        TO ELIMINATE SQUAT;
                                                        reduce speed,
                                                        Sufficiant UKC is to be kept to avoid SQUAT.
