Like so many tools - the impact is very much related to the type of boating you do and the area you are in. No question the technology works as described - and could be very helpful for some. I thought I would be using FLIR all the time, on a regular basis. Was sharing that the expectations of how I thought I would use it didn't exactly pan out.
Jon, I also have dual E120's. The distraction comment was not related to display real estate, rather captain scan time. When underway I am continually scanning the environment visually, radar, chart plotter, frequent glance at the Smartview on engine status. It was adding in that additional scan element. I know that I am not the most experienced captain out there - so I stay very focused on what the boat is doing and my surroundings.
If you have a mate on the helm that could focus considerable time on that screen, then yes. I tend to have that mate forward on the helm so they have a different point of view watching for lights. They are looking to pick up a set of lights that might be blocked by the hardtop posts from my sightline. When we are out in darkness its typically because we left our slip before daylight or we are headed back to the slip after dark. The area around our slip for several miles is heavy recreational and commercial traffic. This is both ICW and after leaving the inlet nearby. Yes I am concerned about obstacles in the water - but highest level of concern in this area is identifying boats around me and knowing what they are doing.
Very small craft who will not show up on radar easily - great positive impact of FLIR.
This makes me think of another technology tool: AIS. I don't have AIS, but I thought that would be an early addition to this boat.
Once again - my preconceived instinct didn't hold up for our boating situation (back to the everyone faces different factors).
Our environment is very heavy traffic from small craft up to 150ft+ yachts. Once we leave the inlet, all the same as inside plus oil tankers, cargo ships, and other large vessels. This is between Miami and Fort Lauderdale.
I have left the inlet, moving 2-3 miles off shore and had 38 radar contacts (all were vessels) on a 1.5NM scan. With an AIS display running on my iPad, most were not transmitting an AIS identifier. The ones that were, were large enough vessels there was no doubt about a radar return.
My feeling is that AIS would let me know about large(r) vessels, but most of the traffic AIS would not help with. I use AIS apps on the iPad at times, but have not integrated it into the vessel.
At the end of the day - there are all types of tools - some fit each of us better than others.
Just my random thoughts,
Mark
