Introduction
Tides and currents can be very helpful in navigation when you know how they work! Navigating by the stars and using wind, tide and current are all part of the fun of sailing. But when you want to go somewhere specific, knowing about tides can help you make sure that your boat doesn’t get stuck on a sandbar or end up in a channel when it isn’t deep enough for your draft (the depth between the waterline and keel).
Tides and currents affect where you want to go and how long it will take to get there.
Tides and currents can be very helpful in navigation when you know how they work! The reason behind this is that tides and currents are caused by the gravitational pull of the moon, sun and Earth’s rotation as well as by wind, underwater topography and other factors. They also can have a dramatic impact on where you want to go and how long it will take to get there.
For example, if you are planning on sailing around an island that has both strong tidal currents and high winds (such as many islands in Hawaii), then it would be best to plan for your trip during low tide so that your boat won’t get swept away from shore or into shallows by waves from passing boats or large ships.

Tides are caused by the gravitational pull of the moon, sun and Earth’s rotation as well as by wind, underwater topography and other factors. The tidal range—the difference between high tide and low tide—can be significant in some locations.
Currents are caused by tides, winds, underwater topography and other factors.
Currents are caused by tides, winds, underwater topography and other factors. Underwater topography affects currents because currents are caused by tides and tides are caused by the gravitational pull of the moon, sun and Earth’s rotation as well as by wind.
When planning a sailing trip, consider whether the current will help or hinder your progress during your time on the water.
When planning a sailing trip, consider whether the current will help or hinder your progress during your time on the water. Currents can be helpful or hinder your progress depending on where you are and whether they’re flowing with or against you. All currents are strongest at the surface, but they also affect the water below—strong currents can cause you to drift off course (if it’s not blowing too hard). Tides and currents can help you get to where you want to go if you know how they work together.
Know about tidal variations for best times for launching or coming into port.
You can tell the time of high tide by looking at the moon in the sky. During full and new moons, when the moon is on one side of Earth, tides are highest; during first and third quarters, when the moon is opposite Earth, tides are lowest. The height of a tide is a function of how closely each object orbits another: if two objects are very close together in space (like our moon and Earth), it takes less time for them to come into alignment than with objects that are farther apart from each other.
The height of an ocean’s tide varies depending on many factors: distance between two bodies in space; gravitational pull between those bodies; shape or size of those bodies; wind conditions at sea surface level or near shore; water pressure under water surface level (this one’s tricky because even though it might be calm at high tide time due to lack of waves crashing against rocks or shores nearby areas where currents run fast enough may still experience high winds).

Tides and currents can be very helpful in navigation when you know how they work! They can also be your worst enemy if you don’t understand them.
Tidal variations are important to have in mind when planning a trip, as they can affect where it would be best to travel. To get into port, for example, it’s best to arrive during slack tide, which is when there is no current pushing against the boat. If we arrive at low tide but there is still current pushing against our vessel, we might not be able to dock properly or could even damage our boat if we try docking at an unfavorable time. It’s possible that parts of our vessel like rudders could get caught on something under water and make docking difficult or impossible until the waters begin flowing again during high tide (or until another method of getting back into port becomes available).
Conclusion
We hope this information helps you in your next sailing trip! Tides and currents can be very helpful in navigation when you know how they work. The next time we’re out on the water, we’ll keep these tips in mind.
