This Cabin porthole tide clock has a hefty solid cast brass casing, scuttle clamps, bevelled glass front and brass hands with black subsidiary indicators on a light cream face. Tide Clocks are influenced by the orbit of the moon around the Earth. To show this, the tide clock has an extra hand, which makes a complete sweep at the lunar rate of approximately 12.5 hours instead of the normal 12. (Please note: because the lunar cycle varies with the Earth's, there are times in a month when actual tides are a few minutes ahead or behind the clock.) The Cabin range is intended for smaller vessels, or a large yacht’s cabin.
