Why do you think that is? Because every email you send/post to NavList starts a NEW thread. This can be more than a little annoying for those of us who like to keep track of conversations and topics using the "threading" function in their email software. So PLEASE, use the REPLY TO function in whatever email software you use to send to the list, this should stop ALL of your posts being started as a NEW thread. Of course, if you want to start a new topic or conversation then it goes that you should "compose a new message or email". I suppose there could be some bug in the AOL email software which starts a new thread regardless, and I wouldn't be a bit surprised, as AOL software is well known for it's bugs and sometimes non-compliance with internet protocol standards including SMTP. > program for radio transmissions.

So you use AOL when in range for "cellular aircard" or WiFi hot spots which by definition means you have to be on or NEAR land as both of those technologies don't work very well for long haul at sea data transmission. And if I understand you correctly you don't use REPLY TO when using AOL email software. > For HF email I use the Winlink 2000 system via Ham radio and use a program > called AirMail. For sat comms we use a service called Seawave which uses the It seems rather obvious that for long haul at sea communications one only really has two choices: HF and Satellite. I suppose I could drag a long cable behind the ship but that could get kind of messy with the rudder and prop and the necessary repeaters would get kind of heavy. Does the AirMail software have a "reply to" function? I'm willing to bet that it DOES have a REPLY TO capability.

Connecting to the net via iridium or INMARSAT can be pretty darn expensive so I fully understand why you would want to use it sparingly or for short duration voice only. Even batch processing of email through a satellite link can get expensive especially if large attachments are used either incoming or outgoing. BTW, this attachment problem is why "GRIB" files are sent and used by most newer weather depiction software for at sea weather graphics. GRIB files are small in size yet depict a lot of information, hence they are very suitable for use in low bandwidth applications like HF communications. > When I reply to the list, i usually hit reply, then delete all the extra > text, which is what i do as a matter of course here or ashore. When using sat Just above you stated that you did NOT use the REPLY TO capability in your AOL email software and that is all you use to post to NavList.

And now you are back to composing new messages which is what I suspect you do ALL the time when posting to NavList, hence the reason your posts to NavList always start a new thread. I have two technical challenges for you. First, post a message to NavList that does not use the AOL email software, you can use AOL to get online if need be, but not for email or a post to NavList. Second, post a message to NavList that is a reply to an existing topic that will actually thread under the topic instead of starting a new thread. Somehow I am not very hopeful, especially for the first challenge. > I do not think that at sea comms is too far afield for the list, as even in > my short time on here, we have gone on tangents far less germane to > navigation than at-sea comms. If I am wrong on this, I will certainly end the > conversation with this email. I guess we just disagree on the issue of whether at-sea communications falls within the definition of navigation. I would agree that it is essential for accurate weather prediction and analysis. And that good weather information is essential for making good time between between ports and for severe weather avoidance. The simplest solution is just a good basic HF radio receiver. So IMHO it is only tangentially related to navigation.
