I only mention these distant stars as a way of introducing the role the solar system in general, and the moon in particular, plays in our daily ocean tides; an astronomic phenomenon of which most people are completely unaware. Tides are the rise and fall of sea levels caused by the combined effects of the Earth's rotation and gravitational forces of the sun and moon. With the moon taking nearly 30 days to orbit the earth this means the tides change approximately 1 hour each day and the rise and fall of these tidal changes depends on where the moon is in relation to the sun.
When the Sun and the Moon are aligned, as in the new or full moon phase of each month, the gravitational pull on the earth and its oceans is strongest, producing large tidal bulges (referred to as spring tides) with correspondingly higher and lower tides. Conversely, when the moon and sun are at right angles to one another in the quarter moon phase, the weaker tidal bulges (called neap tides) produce low tidal change. In the ocean the tidal range is usually less than 2 feet but, in coastal areas, the tidal range can be anywhere from near zero in the Mediterranean & Caribbean Seas to 53 feet in the Bay of Fundy. In Vancouver the tidal range is generally around 12 feet. Learning to read and understand local tide charts is indispensable to mariners if they want to avoid accidental grounding or being carried away because they haven't let out enough anchor rode.
Of course with the Moon just being something that revolves around the Earth, which in turn revolves around the Sun, a star that revolves around who knows what and fades into insignificance in comparison to most of the others in the Universe, it's hard to put it all into perspective when you are either lying on your back in a field or floating out in the ocean. But once you can find a star you recognize and determine whether you are either east of the sun or west of the moon you should be okay.
