Network connected marine electronics system

A system comprising:

• a marine communications network enabling wireless communications functionality on a marine vessel;
• an electronic navigation device for the marine vessel comprising a processor and a memory storing a first set of marine data comprised of a plurality of items;
• a mobile communications device comprising a processor and a memory storing a second set of marine data and a mobile software application including instructions executed by the processor of the mobile communication device to
• receive and store, using the marine communications network, a marine data set comprised of marine data indicative of at least a portion of said plurality of items,
• determine whether the second set of marine data matches the first set of marine data, and
• create a new data set based on a combination of at least a portion of the first set of marine data and the second set marine data when the first set of marine data and the second set of marine data do not match.

A system comprising:

• a marine communications network enabling wireless communications functionality on a marine vessel;
• an electronic navigation system installed on the marine vessel comprising a processor and a memory storing a first marine data set comprised of a plurality of items, wherein each item of said plurality of items of said set of marine data stored in said electronic navigation system comprises an updatable version identifier that is indicative of a version of that item as currently stored in said electronic navigation system;
• and
• a mobile communications device comprising a processor and a memory storing a mobile software application executed by the processor to
• receive and store a marine data set comprised of data that is indicative of at least a portion of said plurality of items and an updatable version identifier that is indicative of the version of that item as currently stored in said mobile communications device,
• generate a new set of data comprising marine data set associated with at least one of the updatable version identifier and one of a first timestamp and a second timestamp that is indicative of a latest data update to said particular one of said items.
