TideComp 2000

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?

TideComp 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.

Gives rapid 24 hour graphs showing rates of rise and fall and spot tide heights at any time throughout the day.
Prints monthly tables of high and low tide in familiar tide table format.
Tables can be saved in HTML format for use in web pages or in other documents.
Computes under keel clearance at any state of the tide.
Indicates hours of daylight and darkness and Moon's phase.
Valid until the year 2050,  
Data base of over 4000 locations covering all continents (including Antarctica) and hundreds of isolated islands.
Search functions allow tide stations to be selected by name or geographical location.
Point and click' from a zoomable world coastline chart atlas maps to rapidly locate and identify tide locations.

本人将 TideComp  与英版航海潮汐表2001，2002，2003，2004版随机对比， 潮时误差10分钟内，潮高误差0.5米内。手头无中版潮汐表， 没对比过。

软件为30试用，不知哪位能破解？

航海用的天文历， 不知各位合用不？

本人将 Offshore Almanac 与英版航海用的天文历2002，2003，2004版随机对比, GHA相差0'.3以内，DEC相差0'.2以内。手头无中版天文历， 没对比过。

似乎很不错

不合用，英文版，而且还不是针对中国的读者，不如《天文普及年历》用着方便。
