Hi guys 
I just want to check when new GRIBs are available via Saildocs. I've looked at the Saildocs website but I just want someone with bigger brains than me to confirm that my understanding is correct. 

GFS
- Model is run every 6 hours (0000 UTC, 0600 UTC, 1200 UTC and 1800 UTC) 
- Model is available via Saildocs 4-5 hours after its run (so in Sydney, the 0000 UTC model is available at 1500-1600 AEDT,  the 0600 UTC model is available at 2100-2200 AEDT etc)

ECMWF
- Model is run twice a day (0000 UTC and 1200 UTC) 
- Model is available via Saildocs 6.5-8 hours after its run (so 1730-1900 AEDT and 0530-0900 AEDT)

RTOFS
- Not sure when the model is run, but it's once a day
- Model is available via Saildocs at 1100 UTC (2200 AEDT) for 3 hr increments, and 1700 UTC (0400 AEDT) for 6 hr increments

I have some more rookie/newbie questions..

- to receive the UKMO GRIB, I assume that I need to download it via PredictWind Offshore subscription, then upload the GRIB into Expedition manually. Is that right? Does anyone know when it's available in AEDT?

- to receive the Mercator model, heck I have no idea. I don't think it's available via Saildocs so I assume it's also via PredictWind Offshore - followup question - when is it available in AEDT?

- is there a way to check whether a new model is available? Or would I just wait until just after the latest stated time to get the model (eg for ECMWF, I'll download it at say 1915 AEDT and 0915 AEDT)

- Franks Weather page says the RTOFS model is available around 1700 UTC - I assume he's referring to the model with 6 hr increments. Should I just be downloading the 6hr increment model and not the 3hr? 

- In the Saildocs window that pops up with all the models you want to download, where the options for 'every X hours for X days' etc appear, do I have to make sure that I choose a certain resolution which corresponds with the resolution that is available via Saildocs (I couldn't quite find info on this question on their website)? Or can I choose any resolution (file size questions aside) 

- If I select 'Subscribe (email)', does that automatically download the GRIBs as they become available each day? Or is there some sort of additional process for this option? 

- I don't have Expedition on the laptop I'm currently typing from, but I recall there's another option to download a currents/ocean data GRIB (I think when you're running a route (in the Optimisation ribbon) and I was wondering when this data is generally available? I've just been selecting that option every time I optimise our route

Thank you so much!
