Mobile Content and Your Boat


Earlier this year I received an Android phone as a birthday gift. Of course the first thing you do when you get a smart phone is go searching for the best Apps available. There are Apps that do useful things like track your bank accounts, and there are Apps that do useless mind-numbing things like blowing bubbles.
Eventually, once I began to comprehend how my phone works, I started looking for Boating related applications. There are actually more than I thought there would be. There are Navigational applications (my favorite is still from Navionics), tidal information, weather data, and quite a few others.
I’ve even read a couple articles about applications that control various functions of the boat itself. This is where I become a bit leery of the how fast things are advancing. The fact is that paper charts have not been completely replaced , yet people are willing to allow their phone to control things like auto-pilots and power distribution panels.
The National Marine Electronics Association(NMEA)  has made incredible progress in getting a protocol established that enables most marine electronics to interface. While the people at Apple, Google and Microsoft are all very bright – I'm not certain that any thought has been given to whether any of these programmers have even been on a boat, let alone piloted one.
The London P&I Club, one of the world’s leading mutual marine liability insurers, published in their StopLoss Bulletin that, “Onboard communication has improved significantly over the last few years, with technological advances enabling crew to use mobile phones and laptops to stay in contact with family and friends ashore. However, the use of such equipment at inappropriate moments may distract crew from the navigation or operation of the ship.
“Another issue is the risk of being exposed to excessive information and simply being unable to process it all. Bridge equipment is increasingly sophisticated and it can provide the crew with access to extensive information regarding the relative positions of other ships. But, unless it is used in a focused manner, it can confuse, rather than clarify, and ultimately prove counter-productive.”
There have been accidents on inland waterways, as well as intra-coastal waterways caused by the distractions of Skype calls, streaming news reports, and Email/Texting. Often, these  activities are being conducted on equipment either adjacent to or on the same screen as chartplotters, AIS displays or RADAR supplies.
There is no doubt that great advances have been made in what is possible to accomplish with technology, particularly within the marine industry. In 2004, the idea of linking different systems together seemed like something from the realm of "Star Trek." Now, in the world of tech, there is an app for everything it seems. The question isn't whether we “can” control a boat from an iPhone, Droid, Blackberry or Windows Phone – rather “should” we take this step. Eventually, sure but this is where the NMEA should monitor closely what the mobile device developers are “attaching” to boats. The most dangerous of the four major smart phone’s to the marine industry is the Droid phones – because anybody can make an application for them. This is great for the general public, but can mean disaster to mariners.
We’ve all had that person checking their Twitter or Facebook account cut us off on the road – boats are not quite as responsive. Already there are apps that are trying to replicate the functionality of AIS systems. What happens when somebody loses reception, or they forgot to plug in their phone the night before when they happen to be in a very busy port? Call me a cynic – but I can see bad things happening.
The bottom line is that there always seems to be a trade off for progress made to quickly.
As always, I appreciate any comments.

METS tp Feature NMEA 2000 ConnectFest Demonstration

From Professional Mariner:
(11/7/2011)
Marine electronics from different manufacturers communicate seamlessly on the network
The NMEA 2000® open industry networking standard will be demonstrated live at a free ConnectFest event on November 16, 2011, at the Marine Electronics Trade Show (METS) in Amsterdam. Dates for METS are Tuesday, November 15, through Thursday, November 17.
An open plug-and-play system, NMEA 2000® allows devices to be added to or subtracted from a network with no down time.
The METS ConnectFest in Room D201 will be an all-day event, from 10.00 to 15.30 hours. A number of diverse manufacturers will be interacting and demonstrating the interoperability of various products in a network environment.
The demonstration provides an opportunity to have direct conversations with manufacturers who have adopted and developed products using the NMEA 2000® protocol. New developments in power distribution and alarms will be demonstrated.
The NMEA 2000® marine open network standard was developed by companies both within the industry and outside it. More than 40 marine organizations invested time and resources to create NMEA 2000®, which is based on CAN (Controller Area Network). Other experts, including Kvaser AB, Oklahoma State University, Sun Microsystems, and the U.S. Coast Guard Research and Development Center, contributed their expertise under the guidance of NMEA.
Today, NMEA 2000® is maintained by the industry's global NMEA 2000® Technical Standards Committee, with more than 100 companies worldwide participating.
In addition to demonstrations, the NMEA ConnectFest will provide answers to questions related to costs, installation, configurability, and scalability. Among matters discussed will be the need for all products on the NMEA 2000® network to be NMEA 2000®-certified. The NMEA 2000® protocol requires that its products and messages have certain priorities built in for ensuring safety on the sea. Only products certified for NMEA 2000® use can communicate with each other.
ConnectFest will also provide hands-on experience with the NMEA 2000® cable and connector system, designed to save weight and installation time and ensuring future connectivity for products on a vessel.
The International Electrotechnical Commission (IEC) has adopted NMEA 2000® as a network standard for the use on SOLAS class vessels with its standard 61162-3. Lloyd's register has accepted the NMEA 2000® cable and connectors.
A 30-minute presentation on the history, structure, and benefits of NMEA 2000® is scheduled for 10.00, 13.00, and 15.00 hours on the day of ConnectFest.
