I'm a big fan of iPads on sailboats. They have a multitude of uses. I will always have a dedicated GPS Plotter at the wheel because they are more robust / waterproof but for planning etc. the new iPad stuff is hard to beat.
My original Mk1 iPad has now been replaced with a Mk4 for my daily use and the Mk1 has been donated to the boat. It has been mounted on the Nav Station panel using the WALLEE iPad mount
The cable connection will be tidied up any year now.
Eventually I will have a WiFi system onboard transmitting navigation instrument data. The technology is improving every year. This is DMK app displaying wind speed, boat speed, wind angle and depth. Nice......
Navionics charts of Biscayne Bay on the Navionics App.
Vessel lights on the COLREGS app.
And the list goes on....................................................
