Description | |
Summary | TotalTide is designed exclusively for SOLAS shipping. It provides instant tidal height and stream predictions for the world's commercial shipping routes. Tidal heights for the world's Standard and Secondary Ports are displayed clearly and concisely both in graphical and tabular format. It uses the same prediction algorithms and Harmonic Constants as the Admiralty Tide Tables. Tidal Stream rates, for more than 3000 positions world-wide, are presented on a chart-based diagram. TotalTide enables selection and, simultaneous, calculation of tidal heights for multiple ports for up to seven consecutive days. Results include periods of daylight and nautical twilight, moon phases and a springs and neaps indicator. Under keel and overhead clearance can be calculated and displayed as a simple, yet comprehensive, graphic to ensure safe passage-making and port entry. The user can also utilise the prediction algorithms by inputting privately held harmonic constants if desired. One CD includes the calculation program and seven geographic Area Data Sets (ADS) providing global coverage. A simple permit system provides access to the area(s) of the world required. The subscription service lasts for 12 months from the date of purchase. Coverage can be added to at any time. TotalTide is Windows based and is designed to run on a PC with a 200MHz processor or better, with a minimum 64Mb RAM and CD-ROM drive, running Windows 98, NT, 2000, ME or XP. |
