Internet Access While Sailing? 199
ryan schroeder asks: "My mother is sailing to Hawaii this summer and is wondering about solutions for checking e-mail. I know a cell phone modem won't work and a satellite phone sounds a little expensive. I bet someone out there had looked into this. If anyone has a direction to point me to that be great." It would be interested in hearing if any of you folks have gotten Internet access working while out at sea and what degrees of success you've had with it. Who needs land anyway?

I was in fact perfectly serious, amature radio in the right band would be a good solution, you might have to get a license for a non-standard amature band to get the distance, but no other group tries to get low cost radio working, and that is the solution needed here.
I knew the guy who ran (runs?) amature a large radio network. It works, but by his own words it is slow. Maybe that has changed and maybe not - I don't know. Certinaly the band he was working in doesn't have the distance abilities that sailboating needs, but he can easially set you up in a band that will deal with that distance. He would love to help too, just for the challenge of it.

In effect, a set of messages is already held on a sub, and only the ID of the message is transmitted.
There's some question about the effect of ELF waves on biologicals...
Whale/dolphin modes of communication are much higher frequency, and should support signal carrying. I agree that this might be a very promising method of communication. Hopefully those with some know-how will spot this thread and illucidate the matter.

Third up, you -could- use amateur radio. It's pricey and interference is likely to be high right now (high sunspot count), but the speed's not really going to be -that- much faster than the other two options.
Lastly, for a REALLY good connection, load up the vessel with a tightly-wound reel of optic fibre. Plug the other end into a DSL or cable connection, and lay cable as you sail. You should get the full speed of the ISP's connection, that way.

Unless things have changed significantly in the year or so ago since I've heard from them, Inmarsat B equipment is extremely bulky and heavy and can't be carried on vessels under 100'. This is a huge and expensive boat, making it cost-prohibitive for most sailors even if the cost of the equipment itself wasn't already.
If my memory serves, the suitcase-sized stuff is either C or Mini-M with maximum data rates in the slug-like 2400-9600bps range.
Telephone services via SSB were all but shut down a few months ago, which was probably no big loss since the satellite-based systems are both cheaper to use (SSB phone service was billed out at $5/minute!) and more reliable. I don't think SSB is a good long-term bet.

Alternatively, Cellular is probably the most cost-effective and easy to use option. The downside is the range is limited to about 10-15 miles offshore, depending on conditions. You will want to use a marine-grade cell phone, rather than a hand-held, in order to get the best range. You can probably rent one of these.

It's long gone. It was WAY ahead of its time, dating from about 1970. AlohaNet was a VHF radio inter-island packet switching system built by the University of Hawaii, because inter-island data links were very expensive. The basic idea was that stations could send when they heard nobody else sending, with backoff to deal with collisions. Slow, though, due to the available spectrum space. Alohanet was very influential; Ethernet was based on the same idea, and Alan Kay described Ethernet in 1975, when I first toured Xerox PARC, as "Alohanet with a captive ether".
There's a tradeoff between bandwidth, propagation delay, and utilization in Alohanet; you can't make a fast wide-area network that way, because the collision-resolution time goes up with distance. Wireless LANs, though, work fine.

We wound up using an Inmarsat phone by Magnavox (back then only Magnavox and NEC were *seriously* in that business, but Nera and Thrane & Thrane seem to aim more at the serious marine market now.) Inmarsat is rather expensive, but other than the protocol performance problems inherent in the horrible latency to geosynchronous orbit, it works reliably. Prices have come *way* down from the $17/minute of a few years ago to monthly fees of a few dozen dollars plus airtime of $2-5/minute.
The Magnavox phone we used had a folding parabolic antenna which had great response, but was finicky w.r.t. alignment. Many of the newer (and lower cost) phones use multiple phased array antennae which are much better suited to a smallish boat - you don't want to be trying to keep an antenna pointed straight at the bird while on the seas in a rocking boat! You get what you pay for here. There are some decent entry-level phones that are compact, easy-to-use, and affordable, but they often have data rates of around 2400 bps! 64 kbps phones have been out since late last year.
Also, pay atention to how you get connected to the Net on the ground end. I've heard (second-hand) that the Dutch PTT has good Internet access and competitive rates.
Make sure the computers on both ends have RFC 1323 (the LFN RFC) compliant TCP/IP stacks. This makes a *huge* difference in the way your machine will handle geosync latencies! Most modern machines will have this feature by now, but if it's missing on either end, you'll see big performance problems.
Inmarsat is probably still the best bet for a boat because you get voice and data and they're on pretty much every ship in the world, which can be handy for checking weather, etc. from your neighbors. (Learn the wetiquette for this before spamming folks at high connect charges!)
Iridium would have been a good choice, but sadly, they're gone. Globalstar is still an option, and one that might work for you, but despite their name, they're not global yet, so coverage may be an issue. Globalstar phones though, have the advantage of being seriously multimode: Globalstar satellite, AMPS analog cellular, CDMA Digital, or the crude, brain-frying GSM. These could save a lot of money near shore, if roaming doesn't bite you worse than satellite time!

There are two ends to your problem, the boat end and the land end. You'll need to have radio gear on land, turned on 24/24, 7x7. Given how crowded the HF bands are these days, its not practical to set up your own landside transceiver. There is no way to connect to a dialup ISP these days by tunneling through a radio connection, so abandon that idea now. But there are many boater email services available, a few are linked below.
Satellite gear is expensive, ignore it if you can. It is all high-latency 1200 or 2400 baud packet transmissions, and you end up using the providers email service, and they aren't in the email business. You can't really use satellite phones to make modem calls to any ISP, but if you get desperate set up a 110/300 baud FSK modem on a phone line at home with UUCP on a linux box.
I would assume the boat is already equipped with a good HF radio. If not, then start shopping for a higher end radio with computer control designed to integrate with laptop computers and an SSB HF modem. Read a few boating mags, and a few amateur radio mags for reviews, and search deja for other reports.
In addition to a good HF rig, you'll need a good HF modem. Look at kantronics [kantronics.com] website for starters.
Get your mother trained up on HF radio operations. There is no easy shortcut when you are 1000 miles from the nearest land. It is as important as learning how to sail and basic emergency procedures.
No matter which route you go, it will be necessary to have a server landside to store the email and filter out spam whenever possible, and to intercept messages containing large attachments. Keep the email address off the internet, don't post it prominently on a web page, or post to usenet from it, or spam will follow. Give it out only to those who your mother wants to communicate with, and send out an explanitory email to her friends not to try to send pictures or big attachments.
The link will be between 300 and 1200 baud, so plan accordingly. But any modern HF gear can run in unattended mode, so picking up email can happen over a period of hours.
There are a bunch of commercial email gateway services to boaters.
Check out Message Center [std.com], Mobile Marine Radio [wloradio.com], the HF on Board [hfradio.com] guys are cool for DIY, and globe wireless [globewireless.com] are expensive but reliable.
Disclaimer, I've used globe, they work but you'll still need to know what you are doing on the boat end. And they cost a lot of money. And they don't have any spam filtering, since they make about $2 to $5 per message transferred.
Test out the service for at least a month before heading off to sea. Try it on a shakedown voyage as well. No sense on spending all that money and time just to haul a bunch of useless equipment to hawaii.

All you really need to do is leave your phone line dipped in the ocean before you leave, and plug into the Pacific on the other side. But watch out for Aqua-Boxers; they might use your phone to set up a party line while they are on cruise.
Amature radio? (Score:4)
I know folks into amature radio can get internet connections pretty much anywhere. Connections are 1200 baud, and it is shared, so don't expect much. Web browsing is out, but email can work.
Note that my information is a bit old in this area. I used to know one of the admins for the Minneapolis amature radio IP network, but that was a few years ago and I've since lost touch. Seems like someone in this crowd would have a solution though.

Some Ships Have Access (Score:4)
We went on a New Years cruise on the Norwegian Sky and it had an Internet cafe and in room access (via a fake dialup to an on-ship extension). It is EXPENSIVE and slow, but it works.
I know this was the first ship with access, but supposedly most cruise lines are now putting it in the older ships as well.
It was funny to be checking mail in the Internet cafe and have people ask the help guy why they couldn't connect to AOL and what was the local number out there. Maybe AOL should consider putting some POPs on bouys. :)
eMail access options (Score:4)
Being a bit of a chinch mite, I'd opt for the pocketmail solution, you just have to wait to do email until you get to shore.
Ham Radio? Could work (Score:4)
Additionally, they would have to learn to understand Morse Code at a rate of 5 words per minute (in order to get Shortwave privileges, which would probably be necessary for getting email in the middle of the ocean).

Satellite probably best bet (Score:5)
1. Satellite comms, preferably Inmarsat or some other well established crowd with geostationary sats. Yes, it's expensive, but kitting a boat out for that kind of voyage is _really_ expensive anyway, so maybe another grand or so won't hurt. Check out:
http://www.inmarsat.com/suppliers/index.html
Inmarsat-B may be the one - 56kb modem equiv, fits in a suitcase.
2. SSB radio, but I've never heard of anyone running digital comms over it. And it depends on weather conditions how far it goes. But, it's nice to be able to hear real live crackly voices 1000 miles from land...
3. Set off the EPIRB and when the come to rescue you tell them you're fine but could they send this message for you?
What boat is being used here? Are they looking for crew?!

I think that of all people he should be the most knowledgeable about the issue of 'net access from the middle of nowhere. There may even be information on his site -- plenty of stuff there.

1 Wire cutters
1 RJ45 crimper
1 foot of electrical tape
300 miles of CAT5 cable
First, locate the underwater cable running to Hawaii. Use the wirecutters to strip to pierce the shielding and strip the end of your CAT5. Use the electrical tape to splice into the cable. Use the crimper to put an end on the CAT5. Now you can sail anywhere within ~300 miles of your splice. For longer distances, use a longer cable.

HF/SSB Solutions (Score:5)
On the satellite side, there is exactly one product on the market. I don't remember the name or mfgr, but you can find them in any boating gear catalog. This is a small, self-contained unit with a small keyboard and LCD display. They go for about a grand, plus you need to subscribe to service and pay per message. Not cheap, but I hear they work quite well.
The other, and much more common, option is HF/SSB/Marine Radio. Any ocean-going vessel will (or should) have a SSB radio, although you need a fairly decent radio and a good antenna for data use. If you have a General (or better) class amateur radio license, then your choice is simple: WinLink 2000 http://winlink.org/k4cjx/ [winlink.org] is pretty much the defacto standard for amateur radio internet email. Yes, the software runs under 'doze, but it is free, and the service is also free, run by fellow ham operators.
If you do not have a General Class license and are operating on Marine SSB frequency bands, there are a number of commercial solutions that work just the same as WinLink. Unfortunately, they are not cheap, and none of them provide service any where near as good as the amateur WinLink setup.
In either case, (Marine/commercial or Amateur/Ham) you will need a radio modem to sit in-between your laptop and your radio. Which one you get will be determined by which service you use. If you go with a commercial provider, they will tell you what unit to use. If you use WinLink, there are many more options, all well documented on k4cjx's web site.
Also, if you are serious about this, I *highly* recomend that you take at least two laptops with you and that someone on board knows how to re-install both of them. Yes, your laptop will get fried, so make sure that you have an extended service policy on it! Why? I guarantee that someone will start the engine, start the anchor windless, or kick in the wind generator while the laptop is plugged in, sending a nasty spike through the electrical system and frying your laptop, or at the very least scrambling memory and corrupting the disk. Keying up 1KW on your HF radio can also do nasty things to your laptop as well.
BTW, I spent nine months as a live-aboard in the carribean, so I know all these issues only too well. If anyone wants more info, I'd be happy to provice all the gory details...
