You can order them from west marine for $26.95. I am glad we are panning to go up that way. I hope this helps.

On the answer plots to the examples the course has been plotted using the feature on the top of the Safe Water buoy (RW "NH" Mo (A) WHIS). By convention isn't the actual position shown by the circle on the bottom of the buoy (with the light shading surrounding it)?

With a semidiurnal tide it is mentioned that typically a 2 day delay will occur before the spring tide. This would also mean that currents are at their strongest 2 days after the Full or New moon would they not?

so in the example below regarding the lighthouse, marina and monument, I assume we add 180 degrees to the lighthouse bc we are directly South of the object but why do we subtract 180 and add 180 for the other two objects respectively?

On the last exercise the current is 4knts with a direction of 360 or "0". I'm confused about the answer, the current vector is at 180 degrees. Can I please have some help to understand this.
Thank you,

In the quick questions part of the module Q5, the answer says “RYA Chart 3 says that to determine the current from tidal diamonds that ALL TIDAL STEAMS ARE REFERRED TO AT HIGH WATER AT VICTORIA” Not sure how Diamond A is associated with Victoria ?

In the the diamond table the Spring tidal stream values bare shown first followed by the Neap values. On the tidal stream atlas, the order of the value on the vectors is reversed. Is there a reason for this. How to not get confused?
