The jpeg compression arrived with Grib2 and most of the raw NOAA data seems to use it, but the NOAA interface in Exp doesn't seem to return jpeg packed data.

Saildocs and PredictWind do both send grib data in Grib1 format. The Saildocs data is often packed a little better, so the file sizes can be slightly smaller.

However, both Saildocs and Predictwind are downloaded as .bz2 files that are then compressed by Exp so the lack of jpeg compression doesn't make as much difference.

Great Circle downloads in Exp are grib2 downloads with an option for jpeg compression with grib2.

Have you looked at the raw data feed into the Exp com port?

It shouldn't make any difference. You should be able to use the one you normally use as Exp only uses the sail at the target for tacking or gybing sections of the route.

It lets you do over-laps and it does have a nice picture.

The sails for the routing output should be the sails at the target angle, even if the output says (-14) for twa.
But yes, do extend the sail chart.

Probably the best solution is to have a free account linked to a different email address. That way you can only download the free data and can't inadvertently break the rule.

It turns out that Saildocs only supports HRRR wit the email interface. Something to do with bandwidth.

Posted. This also has some other grib improvements.

I this is data form the H5000 Websocket, then you are correct - the H5 does not send AIS data and you need a separate feed. Something like an Actisense NGT-1 would work.
