Is the clock operation influenced by its orientation ?


No, you can install it anywhere in the house.


How can I find the high tide time in my area ?


This information can be found in tidal charts, or by clicking on the «Tide tables» link on your left, or from local broadcast or newspapers. If those sources are unavailable just contact us. We will be glad to provide you the exact information.


Can a tidal clock work on any maritime coast of any country ?


Yes, almost anywhere. Anywhere on the globe, tides are mainly caused by the attraction of the Moon. So, just as a wrist watch can be used anywhere if it is set for the correct time zone, the tidal clock will work if it is set to the correct high tide for the area. (see "Setting your tidal clock").

This being said, there are some exceptions to the rule. First, some rare coastal sectors have diurnal tides (only one high tide per day), instead of two like most sectors. This phenomenon is caused by a specific topography and is almost always geographically limited. The tidal clock is not intended for use in those areas.

Secondly, in the upper waters of a river where tides reach (e.g.: St-Lawrence River at Quebec City) the tide cycle, although consistent in duration, may vary for the "Low Tide" position: instead of being equal in duration, the ebb tide is longer than the flood tide.


Do I have to adjust my tidal clock when we are changing time from daylight saving time to standard time or vice versa ?


No, those conventions have no effect on tides.


Can I install my tidal clock on my boat ?








Your tidal clock may deteriorate prematurely if exposed to high levels of humidity, it is up to you to determine if humidity levels can be a concern.


Can I use your tidal clock if I live along the US or Canadian West Coast ?

Absolutely, the vast majority of the Western Coast sectors have semi-diurnal tides, e.g. approx. 2 High and 2 Low tides per day, and the clock movement used in all our products is balanced for those semi-diurnal tides.  Sectors where tides are diurnal (1 High and 1 Low per day) are rare and geographically small.  To verify if your sector has semi-diurnal or diurnal tides, just check on a local tide chart:  semi-diurnal sectors have 4 entries per day most of the time, diurnal sectors have only 2.  In doubt or if you can’t find local information, just ask us by email, we’ll be glad to check that for you.
