Planning a Yacht Refit? Don't Forget Electronic Systems Integration!

Posted by Andy Levy on Dec 27, 2013 4:43:00 PM

We all know that yacht refits are a huge part of the yachting industry. It used to be that a refit meant changing out the finishes, updating the mechanics and adding some key touches determined by the owner.


But with all the technological changes occurring in the past 5 - 10 years, today's yacht refits require a great deal of computer, communications and entertainment upgrades. How many refits is the yacht industry expecting? According to Juliette Warter, Director of International Marketing for MTN Communications:

VoIP Yacht Telephony: Pure-IP vs. Hybrid IP/PBX

Posted by Darren Mayhead on Jun 5, 2013 10:32:00 AM

Yacht telephony has gone through some radical changes in the past few years. Old-school PBX systems are being replaced by systems using Voice over Internet Protocol (VoIP) technology.


With VoIP telephony, the voice server and phones are connected to the vessel's IP network rather than a separate dedicated telephony network.


There are primarily two types of VoIP systems available: VoIP IP (often referred to as Pure-IP) and Hybrid or Converged IP/PBX products.



In this article, I'll discuss the differences between Pure-IP and Hybrid IP/PBX systems so you can make an educated telephone communications choice for your vessel. But first, let’s review the meaning of “telephony.”

5 Tips for Selecting a Marine System Integration Specialist

Posted by Andy Levy on May 28, 2013 12:30:00 PM

Great Circle Systems has been in the yacht IT business since 2000. Since we started, the popularity of on board computer systems has grown exponentially.


As vessels become larger and more sophisticated, and as our work and our entertainment become ever more reliant on high tech wizardry, there is a natural proliferation of on board information technology.  


Designing and installing each technology in isolation can result in a hodge-podge of systems that are inefficient and difficult to maintain.



These days, many people who contact us for IT work already have an understanding that something must be done to organize their vessel’s ever-increasing technical systems. They just don’t know how to begin the process.

Integrated Computer Networks for Yachts: Pros and Cons

Posted by Andy Levy on May 21, 2013 2:03:00 PM


Yacht technology is getting more and more sophisticated every day. We rely on electronic and computer systems to run everything from navigation to telephony. And as soon as we incorporate a new system on the vessel, we wonder how we ever lived without it.


Traditionally, each technical system was installed as a stand-alone entity.  But adding systems one-by-one can quickly result in a hodgepodge of hardware and software systems, each with a unique purpose and configuration.


If you’re like many captains and engineers we talk to, you are feeling overwhelmed by the need to maintain so many stand-alone systems simultaneously.

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.
