TideComp

What's the tide doing in Portsmouth, Phuket, the Galapagos or San Francisco? These are questions long distance cruising and racing yachts frequently need to answer quickly.

Even in regions that appear to be free of tides, such as the Mediterranean or parts of the Pacific, the small rise and fall can produce some surprisingly strong currents. Many Polynesian atolls are impossible to enter when the tide is flowing out and, unless you choose your time carefully, a passage through the straits of Gibraltar or Messina can be disturbingly uncomfortable. And if you have the misfortune to run aground on a reef, wouldn't it be useful to know the time of high tide even if it's only a few centimetres?

The TideComp application provides all the answers, no matter where you are. Its robust mathematical algorithms have been developed over 10 years and used by numerous ocean voyagers and circum-navigators including Whitbread race and Blue water Rally participants.

For local authorities, it is used for planning dredging operations and effluent outflow control, For yacht clubs, it provides advance data for planning events and for Greenpeace, it was the way to obtain tide data for the nuclear test sites of Moruroa and Fangataufa.
