Internet Communications While At Sea?
ubergamer1337 writes "Next semester I will be participating in a college study abroad program known as Semester at Sea. The gist of it is that over four months 600ish students sail around the world on a converted cruise ship, visiting diverse port cities while taking classes when we are between ports. Debates about its educational merit aside, my internet options while I will be at sea will be severely limited. We get just 100 minutes of internet access for the entire voyage, and once thats gone the only internet access we have is a university email address, which is limited to messages under a megabyte with no attachments. I have been pondering different ways to staying in contact with friends and family back at home without running to an internet cafe in every port, and I have already decided that I want to set up a blog that can be updated by email, but I wanted to ask the collective wisdom of Slashdot if anyone knows of any other ways to transmit more then just your standard message through email. Some things I would be particularity interested in being able to figure out would be a way to send photos (encode them as text?), and a way to get Wikipedia pages etc. emailed to me."
My wife and I love cruising, but she runs her own business and can't be away from email for that amount of time. Thankfully there are options now :)
Most ships these days have cell towers on the ship connected by satellite that usually provide GPRS data (and it looks like the SAS one does as well). The problem is they're considered international roaming, which costs tons of money. However, T-Mobile has an unlimited international 'email' option for blackberry for $20/mo that we've discovered includes BIS traffic through the web browser and even tethering (though we've heard conflicting reports about tethering, we've never been charged for it while at sea). There's always Mobi-shark for routing laptop traffic through the BIS, if tethering is a problem.
So we either tether to her laptop, or just use blackberry and a wireless keyboard and end up with a reasonable means of staying connected (granted, at dial-up speeds). Of course there's also the expense of the blackberry and monthtly plan, but that's only going to add ~2% to the cost of the semester.
There's also the option of paying for the wifi access on a per-minute basis. The latency sucks, but if you're using a fat email client (thunderbird, etc) it only takes us 1-3 minutes to sign in, send and receive messages, and sign out. On commercial cruises they charge somewhere around $.50/min, so when there's cabin based wifi we generally opt for that route, since it's way less hassle than the cell option, we don't have to worry about T-Mobile changing their policies on what's included, and $1.50 a day is not a huge price to pay relative to the cruise.
If they're limiting your email to text based only with no attachments, it's probably at their computers (since I'm not sure how they'd restrict you to that on theirs), which means your options for doing funky encoding stuff to get around it will likely be limited. If not, and you can use your own computer, there are tons of ways to convert anything to text (after all, that's what your email client has to do to send attachments, too). The downside is the receiving end would have to be smart enough to know what you're sending.
For wikipedia, I'd say take a copy with you.
Surf the RMS way: set up some kind of server at home that you can email a link to and it will wget it and return the content back to you via email. Since you have seemingly unlimited email access, this might be the most efficient way to surf.
You can also encode images into base64, don't know how big an image it would take before you hit the 1MB limit, but it's possible.

Speaking from experience, we hated going this route. You end up spending all of your time in ports searching for internet, which is really the last thing you want to be doing in some exotic foreign city :)
Plus, we've discovered that it's nearly impossible to research ahead of time, the language barriers alone make googling for it really hard.
That's a ridiculously good point. Applications like Gallery 2 have remote applications that I'm sure can be tuned to your disconnected-mode needs. Simply get everything ready to upload before you login, then when you're online all the human slowness will be taken out of the equation.
55.5 seconds per day doesn't seem like a lot, but if their internet connection is worth their (sea) salt even a 1mbit satellite link is almost 7 megabytes of data per day... assuming everyone else isn't doing the same thing at the same time of course.
If you're really interested in the process, check out Message Queuing. The idea is asynchronous communication between client/server so that you can do stuff when disconnected from the network, and saving your precious "almost" minute per day :)

That is all.
Is it sad that I am more likely to recognize you and your posts by your sig than your name or UID?
There is pretty much next to nothing you can do. Since you are at sea you won't be able to use your cell phone to connect to the web.
A satellite phone with a very very slow dial up connection is your best bet, but too cost prohibitive. Here's a company that does its job fairly well http://www.globalstar.com/
The only way you'll have affordable and uninhibited internet access is to wait until you get to port.
However, for wikipedia you can actually download an offline version of the entire database. For a wikipedia like experiance follow the instructions on this website

Also the raw dump for the english articles is here:

Oh you can also download a DVD version of Wikipedia from that link above. Definitely worth looking at!
Good luck! And definitely have an awesome time. That program sounds interesting and I will look into it as well since I'm a 2nd semester college freshmen.
In essence, you want what used to be the norm back in the BBS days - queued up mail.
Actually, this is still the way email works. It's just that, with the connection always up, you never see stuff waiting around in your outbox anymore as it gets sent right away.

There is a free email option. It requires a HAM license (note: morse code is not required anymore) and a SSB transmiter and a hundred foot antenna. A good SSB unit is around a thousand bucks.
It is only for text based non-commercial emails but functions anywhere (under most weather conditions).
Doesn't sound like a solution for a students desire to surf the web for free anywhere/anytime but email is available and pervasive just about anywhere.

Just get a HAM license, and use WINLINK/AIRMAIL and you can have all the free email you want.
http://www.winlink.org/
http://hamradio.arc.nasa.gov/meetings/HFradioatsea.html
You can run winlink over HF using any HF radio ($200+) and a decent wire antenna on the ship.
Its very popular for sea and also use in remote locations by Missionaries in Africa etc..
You can also use APRS to do automatic position reporting for your ship over HF Radio as well and your family would be able to track your location on a map. http://www.findu.com/
There are also various 'nets' where people all get together on a particular frequency and exchange messages etc. HAM's sill provide national message traffic passing services (Aka TELEGRAMS) for health and welfare messages for people. This is one of the main function that HAM's provide for RedCross, disaster locations etc.
You can come to the net and pick up and messages, and send a telegram to any family friends via HF voice.

Amateur(HAM) Radio is a very very valuable addition to worldwide boating activities.

I fish commercially in Alaska during the summer. If you think being away from your email is heaven, then you haven't experienced the hell that is the high seas. You might have seen Deadliest Catch, but nothing can really explain the weeks of 1 or 2 hours of sleep a night (some days you won't even get that), the constant balancing act of having your sea vessel tossing and turning in 20 foot surf (you can't rest. Standing, sitting, eating, getting knocked to your feet, during every activity 24/7 your body's muscles are working HARD to keep balance.) Getting to shower once a week if you're lucky. Life at sea is hard. After a couple of months of this, every letter, every morsel of home is heaven. Last summer I was able to reach a WiFi point one single day much to my surprise. I managed to connect to AIM and get about a dozen messaged back and forth from my girlfriend before I got disconnected. THAT, my friend, is what heaven is on the high seas.
I checked out the SAS website, and they say "Email Service and Internet Access - Participants can access web-based email accounts, such as Yahoo, AOL, Hotmail, etc. The technology fee charged to all students and lifelong learners provides 125 minutes of Internet access. Internet usage beyond 125 minutes will incur a charge on a per minute basis." So, he doesn't get cut off after 100 minutes. He gets 125 minutes, but he can pay for more. It's not as bad as he makes out.
