Nick Jaffe Nick Jaffe just cleared customs in Coffs Harbour after a 2 year solo sail from Europe. Apart from being an accomplished sailor, Nick also worked out how to make the Internet work for him along the way.

And not just by getting regular weather reports via a Satellite…

Check out his Website, Blog, his Flickr photostream, his Video and his Tweets. And of course, there is a tracking page.Well done, Nick!

I guess it had to be a 27 year old to show us how it’s done…

ericsson_w25 A few friends have asked about the Wireless Broadband Internet and phone setup aboard Te Moana. Last year, we fitted an Ericsson W25 on our boat. Previously, we had USB modems (Maxon CDMA and later the Maxon Turbo modem) with Telstra mobile data plans. Today I still use the (orange) Maxon Modem while we're ashore (handy in the train or at a customer). But while on the boat I take the SIM card out of the modem and plug it into the Ericsson W25 which Andersen Marine installed on Te Moana last year.

Regulars will know that I'm a fan of the iPhone at sea. Even without specific iPhone apps, the ability to adequately browse standard websites make so much sailing related information available at sea and with the built-in GPS (and now a compass), the iPhone is a great backup to other systems on a boat. And it makes phone calls as well...

Panbo, "the Marine Electronics Weblog" (an excellent source of marine geek news) just published a survey of current iPhone apps which extends the functionality of an iPhone on board even more. But wait....can you get Australian mapping for all these nifty chart plotting apps? Not likely.

You see, there is no copyright on US charts, as the US statutes prevent their Government claiming copyright on works which were created by Government employees. That's why software makers can include (raster) charts at no charge.

I think you could make a good case for abolishing copyright on Australian Hydrographic charts.  Having free raster charts available  would encourage more boaters to have up to date charts and encourage the use of low end systems such as those in the survey above as standby systems and on small craft. How about it, Kevin?

And Caroline, next time you talk to Mike Prince at the Australian Hydrographic Office, ask them why they don't freely license Australian charts which we, in effect, have already paid for through our taxes.

Andrea and I have just completed a six month cruise through the south west Pacific Ocean in "Diomedea", our 48 foot steel Van de Stadt. We sailed from Sydney to New Zealand and then onto Tonga, Fiji, Vanuatu, and New Caledonia as part of the Island Cruising Association Pacific Circuit rally. We returned to Australia. During that time we were able to use a variety of communication mediums to keep in touch with those nearby and those far away.

Radio and Satphone

We maintained a blog, which was created using either email or internet. About 99% of the time it was done by email as internet access was very infrequent.

Email entries can be done anywhere and anytime so long as you have either HF/SSB radio with Pactor modem and computer, or, as we did, Iridium satellite phone and computer. One can upload text easily via email but pictures are much slower and more expensive on the satphone. We found the Iridium to be excellent.

We used two ISP's for email: Sailmail and UUPlus. The former was good to start with but it became increasingly difficult to maintain connections as time went on. The latter was very reliable. The Iridium phone was used extensively to obtain weather information, mostly in the form of GRIB files but also in text forecasts in various countries. Of course, regular emails were sent and received. Occasional voice calls were done as well.(One can also take the phone into the liferaft as the occasion demands.)

The iPhone at Sea

At first glance, the recently launched iPhone is ideal for use on a coastal cruise. It isn't just a phone with a built in iPod. It has a GPS built in, its web browser is superior to any other mobile phone browser and well suited for small data entry tasks such as using the skipr.net "Where is my boat" site. On the surface a great phone for marine use!

IMG_6799 On my recent sail North on Breakaway, the iPhone hadn't been released, but I did have a "Touch iPod", which has many of the iPhone capabilities. Breakaway had WiFi Internet access through the Ericsson W25, so I used the iPod to great effect to keep up with my emails and also used its mini browser for log entries to the Skipr system. For much of the time I didn't need my computer because the iPod had all the Internet access I needed. When I needed a larger screen or more extensive text entries, my laptop could also conveniently connect to the system.

So how about using an iPhone to do everything?

P7070280-1 Until recently, this famous shack in West Bay (Middle Percy) was as close as anyone got to a telephone between Rosslyn Bay and Mackay...

As good as Telstra's NextG service is, with a conventional mobile handset or internet modem, coverage fades away as you move away from the coast or pass uninhabited areas. So...


Weatherillo.jpgOne of the advantages of having an internet connection while cruising is to have the current forecast at hand at all times. But a wise sailor will still expect the unexpected. As I write this, we're anchored on the Shoalhaven river near Greenwell Point, a stopover on an Easter cruise to Ulladulla. I awoke at 0400 hrs to a few creaks and rattles. The kind you get when something is about to change...
Most recent mobile phones allow users to access the internet. One of our design goals at Skipr.net is to be compatible with as many devices as possible, so we'll do our best to make it possible to update a boat's position even by just using a mobile phone. Many phones today come with a web browser which can be used to access the "Report Position" page. If yours doesn't, you can probably install the free Opera Mini web browser on your phone. Here is what I did to install it on mine, a typical, one year old mobile phone (Nokia 6100 GSM phone using Optus as the carrier):
  1. Configure the handset for at the Optus web site (the Nokia 6100 uses WAP)
  2. Download the Opera Mini web browser by sending an SMS with OPERA to 19994441 (SMS costs A$5.00)
  3. Follow the installation instructions.
Outside Australia, you can find where to best download the OPERA Mini browser here.
I was asked by a Skipr user (hi Mark!) about the size of webpages used for data entry. He is proposing to use "mini M sat" for internet access at sea and is rightly concerned about the data traffic (or rather, the cost of that).
Everyone would have noticed Skipr's, ahem, simple user interface. While a revision is on our "todo list", the current implementation shines with respect to size. The relevant pages (logentry, login etc) are measured in kilobytes.
For example the login page is 0.5 kB. I used an EVDO modem to accurately measure the data transfer of a Log entry session.
Here's what I did:
  1. I logged on with the modem (Minimax EVDO/CDMA modem).
  2. Hit the Explorer bookmark which I had set to the "log entry" page
  3. Entered a position and brief comment and received the confirmation page.
  4. Disconnected the modem.
The total sizes were less than 12 kBytes "sent" and 8 kBytes "received" for a full session. As economical as anyone could expect! For comparison, the "Where is" page takes 180kBytes to load.
By the way, any laptop user on a serious "download size" budget needs to take care to disable any applications which "call home" regularly without invitation. Obvious candidates are applications such as Virus protection and Windows XP(disable automatic updates in the control panel).

I'd be interested to hear about anyone experience with systems out there (good or bad).
