Unfortunately he does not know how to explain this. Tidal Stream = “Drift” which will include the “Set”. Put the Drift at the delta along with the Set and work from there to get the CTS.
I’m glad that I watched other videos first before this one because if this was the only video I’d watched, I’d have been totally clueless. Firstly, you should have stuck to your plan and not allowed the students to pull you off . Once you had made a simple first example, then you could have introduced their questions.
Standard Port Colville is in TZ-1. ( Subtract 1 hr for UT ) As suggested in this factitious RYA Almanac book, Do we have to Subtract 1 hr from your calculation and then add 1 hour for Day Light Saving Time? SPDST means South Pacific Day Light Saving Time. SPDST., therefore you add UT+1 I noticed that you have written TZ-1/ UT+1 in your note. I am confused.
So if the standard port is in TZ-1 (or UT+1, as they mean the same thing), then you do not add on the hour for DST (or SPDST) until you have done the HW/LW time conversion for the secondary port. Hope that helps
there was loads of chances to explain or re-explain how we measure distance with our dividers. this video should be removed imo. not a good example of anything other than how to frighten people off going to see.
