Posted by Andy Levy on Jan 8, 2015 6:21:44 PM

For some, New Year’s resolutions can be tedious. The day after over-indulging (usually at a New Year’s Eve party), we promise ourselves to do better.

Yacht Computer IT Tips for the Holiday Cruising Season

Posted by Andy Levy on Dec 1, 2014 5:00:00 AM

It's almost holiday time and yacht owners, charter customers and crew are primed to enjoy the upcoming cruising season to the fullest. They anticipate the joys of beautiful scenery, water sports, and great food--and they want to share their experiences with friends and family on board and at home.


That means everyone on board needs to stay connected via their electronic devices, including computers, smart phones, tablets, etc. And it’s up to captains, crew, tech support teams, and management companies to do whatever they can to keep yacht Internet connections working well.


You can read our past articles about vessel Internet issues in our Yacht Technology Blog


And now, we've developed a presentation with tips to prepare your yacht computers and yacht Internet b efore embarking on your first holiday cruise. Just remember that this list should be rechecked as you change location throughout the holiday cruising season, as some items are related to geographic location.  Click on the graphic below to view the presentation.

4 Ways to Deter Superyacht Internet Hackers

Posted by Andy Levy on Oct 28, 2014 8:45:00 AM

Imagine this headline:


Hackers Access Bank Accounts, Passports and Personal Information from Superyacht Guests and Crew!


It could happen. Did you know that a yacht in port can leave everyone on board vulnerable to data theft via their Wi-Fi connections? And the hackers don’t need to be geniuses with high-tech systems to wreak havoc with the cyber-lives of everyone on board.


But how is this possible? Don’t Wi-Fi set-ups on vessels have built-in security systems to prevent access from outside parties? They may, but Wi-Fi connections outside of the vessel could allow the bad guys in.

Yacht Electronic Technology Projects and the 80-20 Rule

Posted by Andy Levy on Oct 15, 2014 2:30:00 PM

You might not be familiar with the term "80-20 Rule," but I'm sure you've seen it in practice. Also called the "Pareto Principle," the "Law of the Vital Few," and the “Principle of Factor Sparsity," it states that in many instances, about 80% of the effects come from about 20% of the causes.


I've seen many examples of the 80-20 rule related to yacht electronic technology projects over the years. And as vessel IT systems become more complex and cutting-edge, I think we'll only become more familiar with this concept.

The capabilities of the GCS team have proven instrumental in helping us deliver a world class technology experience to some of the most prestigious yachts in the world.


J.D. Crawford of Savant Systems


I have been working with Great Circle Systems since 2006 when they did the installation of all our networking and Internet communications equipment on our boat being built in Germany.


The equipment they recommended and installed was exactly as we required.  We have had extremely good results with all of their equipment and it has performed as they had advised.


I would highly recommend them to all fellow captains.
