Now, I have to wonder what I would do if I were outfitting a boat today. For $49 you can get a Navionics App for the Ipad that has wonderful charts and most of the features of our very expensive chart-plotter! It uses very little energy, has an internal GPS, which isn't as good as the Furuno but is fine for looking at charts. I would still want Radar, as that has been particularly handy.
Our friend Green at
On Watch Sailing did a wonderful article on installing new electronics to take advantage of new technology and reduce cost.
In the US the IPAD was also an easy source for tides and currents as well as
Active Captain, a wonderful interactive guidebook.
Isobel has some apps also! There are a bunch of Montessori based apps for learning letters and numbers as well as geometry figures and musical instruments (one of her favorites, although she doesn't like the Diggerydoo!)
