GMT and BST

[[70521]]

IT is always GMT onboard the boat, means that I don't have to faff about doing funny stuff with an hour in the summer. Does anybody else use GMT onboard?

Only problem is pub closing time!

Ship's clock & instruments on GMT, watch on BST (never missed last orders yet) - only time I wear a watch.

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.....

 

[dunedin]

Local time every time.
Would seem bizarrely complex to do anything else:
- all other time sources in local time - watch and phone
- crew working in local time - if I say planning to leave by 8am they will assume local time
- all local opening hours in local time - shops, pubs, restaurants, harbour offices, lock gates
- if in tidal waters tide times in local time - eg phone App, if I print a months tudes, or generally if I use a local marina source all in local time.

Why would I use a different time zone (unless operating a jet airline crossing borders 6 times a day)

I don't sail during winter time. Far too cold.

Not so long ago the tide tables were printed in GMT which caused confusion . I recall an occasion when one so called professional made the correction the wrong way so was two hours out.
Tide tables in recent years are in local time which is the far better arrangement.

Reeds is still in UT. It would only be less confusing to have it in local time if you didn’t expect it to be UT. And then you’d get confused when crossing the channel.

It may appear as though my clock is set to gmt and I’m too lazy to change it. Actually it’s set to zone time and I just haven’t taken this boat west or east of 7.5 degrees. That’s my story anyway.

Port of London Authority still in GMT

As is Harwich.

 

[Praxinoscope]

I have two clocks on board, one is BST the other is GMT, opted for this set-up when trying for YM Ocean and needed GMT for sextant sights, just saved one calculation.
Having got used to it I still find it quite useful to have both.

Always use local time and downloaded tables are in local as well. Only slight problem is remembering opening & closing shop/bar times up the Guadiana as Spain is 1 hour ahead of Portugal on the other bank. Portugal (same zone as UK) is considering doing away with winter GMT.

Boating mainly in UK and french waters in summer, GMT as athird "time" is just too confusing to use after BST and French time on the same trip.

Pretty well all french tide tables for atlantic coast are in Heures Legale is French Summertime or French wintertime as applicable, it makes sense, I dont know why we continue to dick around with GMT in the summer.

Ditto, only once I'm more than one time zone away from the U.K., ship's clock goes to local time.

I use UK summer/winter (not UTC/GMT) time for everything on board. I use a tablet for chartplotter, tides, weather, etc so it automatically switches the nav apps i use to summer time. Even if I visit the continent I still keep to UK local time and just rely on my phone to automatically display both UK and local to remind me where i am!

I wonder if any of us still navigate using "magnetic" ?

Generally been "True" and UT for some years now.

Forget all that stuff concerning Cadburys Dairy Milk and the one about virgins.

Well all the time actually coz thats what compasses show.....

Im a fan of having one clock in UT and ships time in local. I do hop around time zones a bit!

 

[dunedin]

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

 

[Blue Sunray]

Pity the poor blokes that find themselves wearing three watches, one for them, one for the crabs and one for the locals.

 

[MM5AHO]

I use UTC, wondering if GMT is accurate enough?
Most tide tables, and tidal almanacs are not in BST.

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