[PUP] ARPA or AIS?

[Scott E. Bulger]

John shared:  We have both and I have to say that whereas Furuno's ARPA is
better than nothing but it is problematic in high seas. & OTOH, AIS has proven
dead on, and when there's a difference vis-a-vis ARPA we know which to trust!



Scott replies:  Interesting, your describing behavior Ibve not observed on
my Furuno system.  I had a Navnet1 6kw model 1943 unit which I then upgraded
to Navnet II.  Both systems worked great.  However we never really saw any big
seas.  10 foot was about average with the occasional 15, but 95% of the time
few if any whitecaps, which is what Ibd assume the radar would pick up.



As far as what to trust, well if you consider the technology involved using
AIS delegates some trust to the other guy, that his unit is reporting
correctly,  A fairly safe assumption.  On the other hand RADAR is 100% on your
unit, under your control.  Considering the number of boats without AIS Ibd
sure feel better about trusting my RADAR than someone elsebs AIS
transmitter.
