GMT and BST

[Blue Sunray]

I dont know anyone with three arms......:ambivalence:

The secret is to use Combined Arms tactics.

So can somebody explain why anybody would want to use GMT on a boat in U.K. waters in summer?
I am struggling to see any rationale.
Unless it is related to using some old fashioned paper tidal atlas which for some reason hasn’t yet moved to local time - but even then, surely only look up tides once a day and use clocks for other reasons more times a day.
I am baffled

Simples, all my tide tables are in GMT, Reeds is in GMT, Coast Guard safety broadcasts are in GMT, BBC World Service is in GMT. Saves faffing about adding that hour on secondary port calculations.

Conveniently, when the sun is as high as it gets each day (in a mean kinda way) at 0 degrees longtitude, the place under it is called Greenwich. Lucky it wasn't Portsmouth, eh?

Actually it was, hence Gosport ('God's port').

But the 19th century Admiralty's Diversity and Inclusiveness Committee decreed that calling it PMT was sexist. So they moved standard time to London, and called it Zulu Time just to show they weren’t racist either.

Local time. Nothing difficult in setting the offset on the plotter and AIS. Then again, it could be said we operate on GMT anyhow, just it stands for Greek Maybe Time.....

I tend to use the local time of where my passage started, so I retain the time zone of the passage plan. I’ll swtch to the new local time once I’m in my destination harbour.

Many a French bar's closing time has been missed by relying on this trusty seamanship.
