Is it. Or is it positional? A fixed GPS has a horizontal antenna face. How is the phone or pad intended to be held when GPSing.
So on an open (but rolling) sea with no major sky obstructions ... im sorry unless you can point me to a reasonably scientifically run study I'm not convinced.
I have no major pad experience but plenty phone experience with sat pos and I would say in reasonably clear sky I will be showing 8-12 sats no problems, with flight mode enabled. 4 is usually enough for a 100m pos so 8 will get you to +/-15m easily. That's the size of a boat radius... 3m or less doable on calm sea
