Staying Connected

Keeping in touch with friends and family and getting information is harder than when living on land. Sometimes it can be your only contact with the outside world. Sometimes it keeps you sane and importantly, safe!

We knew that it would be important to be able to obtain regular weather information while we were at sea. It would be paramount when on passages as we would be outside of internet, mobile phone and often VHF radio (short distance radio) contact of anyone. When you are 3 days from land, it is heartening to know that you are not sailing straight into the storm of the century or that you should get moving because one is nipping at your heels. We were lucky that our boat had recently been used for blue water cruising and that the gear was reasonably up-to-date.

Ever since Guglielmo Marconi made the first transmission from Galway to Newfoundland in 1901, sailors have been making use of radio communication. Harnessing technology honed in the first and second World Wars, the High Frequency radio (HF, known as Single Side Band to our US friends) is reliable and a great communication tool for remote travellers.

Our boat already had a HF radio fitted, enabling us to contact people via radio sometimes hundreds of miles away, the only requirement was that the recipient also had an HF radio with a suitable receiving antenna. This meant that we could contact the Volunteer Marine Rescue (VMR) stations in Queensland and Charleville Radio (a large radio installation in inland Australia) if we were in serious trouble and were making a mayday call. The boat also had fitted a Pactor modem which enabled data, in very V E R Y slow increments to be emailed from our computer via the HF radio. We signed up to a great service managed out of the United States called Sail Mail. This organisation asks for a yearly subscription fee of $250 and in return connects us to its myriad of receiving stations throughout the world to send our messages on, even when we are thousands of miles from land or another boat.

The excitement of receiving email while at sea is hard to compete with!

Our Sailmail subscription also included connection to a weather service operated by saildocs. The information in the weather messages was drawn from historical data as well as current high and low pressure systems building, so the weather predictions were extremely accurate (on the Australian east coast) where there is high monitoring of conditions and less so in area where there was minimal monitoring (most of Asia). We would review weather predictions up to 3 weeks ahead of a passage to see what was trending and also if there was anything changing that could show signs of dangerous weather. The crossings of the Gulf of Carpenteria and the Arafura Sea were great examples of very strong weather systems moving through (driven by the trade winds), but while they were strong they were consistent and we were able to pick our windows to make the safe crossings. Generally we would receive daily and 5 day forecasts while we were in northern Indonesia, because once again, we were experiencing some very strong wind and sea conditions on a daily basis.

So we were able to gain some reliable weather information via the sailmail service. The weather packages come in a concise file (known as a GRIB file) and it takes some practice to understand what the symbols and colours all mean, but the darker the colour and the more ticks on the wind arrows mean a stronger weather system. When there is little wind, I would call the picture an image of ‘pick-up sticks’ because it was just a collection of sticks dropped in no discernible pattern...the only humour I could find at times like those.

We also regularly sent messages to family via the HF mail system to let them know we were ok. The service was limited, as it only sent text data (no pictures or attachments) and we only had a certain number of minutes per week. This restriction could be excruciating as the modem runs at the speed of your old household dial up system (complete with the sounds) circa 1997 and it could take up to 30 minutes to get the right connection on the HF radio dial, dodging through used frequencies and interference. This could be extremely frustrating when you are pinned into the nav station while the weather outside is throwing the boat around and inducing some serious seasickness.

Most of our time in Indonesia the Internet was inadequate to send emails, so we relied on the HF mail service even when we were in port. As we moved west to Malaysia, Thailand and then north to the Philippines we were able to get reliable internet coverage. We bought SIM cards in each country  (sometimes multiple cards because the company coverage varied depending on our location) at a rate of about $7 a week we could be on email, Skype and Facebook and be speaking to friends and family as if we were just around the corner. We also subscribed to the Australian Governments ‘smart traveller’ email system which sends out security alerts for the places you have signed up for. This would be useful to know if there was political strife in a country/ island that we were about to travel to, ahead of time. But getting used to this kind of connectivity was going to be interesting in the months ahead as we spent up to 20 days at sea at a time with nothing but HF mail and our salt crazed imaginations for company.

The BBC World Service is also broadcast for 2 hours each day (1 hour in the morning and 1 hour in the evening) which we could pick up on the HF radio in South East Asia. So we were able to keep in tune with events of the outside world. It was interesting how much I looked forward to these 1 hour segments, often just to listen to the strange special stories that their reporters submerged themselves in. As we did not have access to local television, this was as close as we got to any kind of news stream. While we were in Malaysia, we were lucky enough to be able to tune into English language radio stations on the FM radio, however this was usually pop music and information targeted at the lowest common denominator. Once we made it further east to the Pacific, we could hear the Australian news and stories booming in over Radio Australia. Initially it was really interesting to hear people on remote Pacific Islands telling their stories, until the Australian Federal Government cuts to the ABC meant that the segments were all but eliminated and replaced with Radio National stories. Reasonably interesting for us as we were missing a bit of Australiana, but I imagine less interesting to the islanders who were their intended listenership.

While we were in the company of other boats we would use our VHF radio to stay in contact when within 20nm of each other. We used this regularly when we were travelling for a passage to make sure everyone is still ok and to keep track of anyone who was having trouble or would be arriving later than expected. All boats sail at different speeds depending on the sail configuration, the design of the boat and those sailing it, so more often than not there could be between 1-2 days varying in arrival times of different boats at a harbour for a 400nm passage. Other ways to stay in touch for longer passages would be to use the HF radio at scheduled times on pre-arranged channels (referred to as a ‘net’) to catch up on everyones whereabouts and also to forward weather information if necessary. When we were sailing in April from Sydney to Darwin, we ‘met’ cruisers on the net that were 1000nm ahead of us giving tips on good anchorages and weather systems they had experienced. We did not meet some of the voices on this net for 3 months until we arrived in Darwin at the great Woodstock of cruising in July. This informal radio relationship gave us a great opportunity to meet other cruisers who had 20,000nm of experience as they had already sailed half-way around the world and could help us learn the tips of the cruiser life.

We opted out of the SatPhone option providing phone and internet contact while at sea, connecting you to satellite systems. The initial outlay is quite expensive and because we already had the HF radio we were well covered for that kind of communication. We do know other people who have SatPhones and think they are great and very reliable, but you do pay for the convenience.

Via our sailmail we were able to send a position report to another group called YoTreps who logged all of our positions and placed them on a map, so that our family and friends could see our location. That was always a nice feature because people often don’t know where Taka Bonerate in Indonesia is, so putting a pin on a map made the information more visual. There were a number of bugs in the system and Hugh decided that he wanted to make a better platform for us to report our location and got busy coding. After many hours tapping away at the keyboard and some involvement of our friends as handy guineapigs, keelscape has become our new way of mapping our location.

So for budding cruisers out there we highly recommend sailmail over the HF radio and meeting other like minded cruisers on radio nets, because what else have you got to do while in passage but have a chat on the radio? Also try this website for logging your position and keeping your family notified of your location.
