Working out a course to steer across the tide 2.

Create a transit with the destination and the background.

If you are going from buoy to buoy, this is a very simple approach.

Identify the destination buoy, before you start the leg.

Identify some distinctive feature behind the destination mark, it need not be on the chart!

Steer directly towards the buoy, and then adjust the vessel's course into the tide, until the buoy stays steady against the background and in the original position.

Advantages
Disadvantages
This technique is very simple, and only requires a little practice to perfect. Any technique should be practised before it is really needed. Practice this when there are no hazards near the required track.
It works best over relatively short distances. This is not an efficient method over long distances, especially over several hours, when the tidal stream will change direction.
You are able to stay on deck, the best place for the skipper in confined waters. You must have land behind the destination to create the transit.
If the current changes in strength or direction, it is quickly apparent. You must be able to see and correctly identify the destination.

Conclusion:

A good technique in confined waters, in clear visibility. Especially relevant for passages with difficult pilotage.
