iPhone app for night sailing

While night sailing near shore, one of the most difficult things is to separate the lights from nav markers from the background lights on shore. What is needed is a phone app that when a phone is pointed in a direction it shows the nav markers one should be seeing and not show the background clutter.

This concept could be extended to sailing in daylight too. Consider the number of times you have been confused because although you believe the GPS, what you see is not what you expect to see. The app could take data from charts and display what you should be seeing and you would then feel better about where you are.

Since no chart (paper or electronic) is 100% correct, shouldn't you believe what you see in reality rather than try to make reality match what you see on the chart? If it displays what it thinks I *should* be seeing and I look over my gunwhale and don't see it, how is that helping me feel better about where I am? I am where I am regardless.

Re: iPhone app for night sailing

I think the daytime app would give help in making you more confident in what you are seeing. It is very diff to ID one point of land over another particularly when there are no aids to nav.
I went on the wrong side of "Don' Rock" in the Abacos because I simply could not believe we were making nearly 8 kts in my 28' boat and thought it could not possibly be "Dont Rock". Fortunately, my draft is only 3'10". A pic of what I was supposed to see from where I was would have convinced me.

Re: iPhone app for night sailing

Sorry. I think I get it now. You're saying the app will help you understand that you're in the wrong spot.

I'm on my second cup of tea now. My comprehension should be getting better soon.

Sorry, but I would suggest one who 'needs' such an iPhone app to sail at night might best confine their sailing to daylight hours :-)

Hell, most boats I get on nowadays, I usually need a beach towel or blanket big enough to cover the cluster of glowing crap at the helm so I can actually see ANYTHING outside of the cockpit...

Presumably, you had a GPS, correct? And, a chart of some kind?

Why on earth would your plotted position on your chart be insufficient to "convince you" where you were, and yet a picture on a freakin' IPhone would have done so???

Have we really come to this? :-)

Re: iPhone app for night sailing

I use INavX
A bit expensive but works perfectly Especially at night when you just want to check your position or way-point without having to go down in the cabin to look at plotter and awake the crew Very bright colors Easy to read and also very accurate

I'm with you my friend. Way too much light on way too many boats at night.
