Steve,
On an iPad 3g or 4g there is no reason for a cell contract. The iPad uses it's internal GPS and is independent.
On the recently completed Catalina cruise we used the iPad running the Navionics App. It's for us much easier to use than the Raymarine C80 and has more useful information. The C80 was on, but only used for depth/sonar.
