All autorouting existing today can find a route from A to B only if they are both in open water, while good guidance and planning is most needed in cramped complex waterways with a maze of variables.
A unique breakthrough in boating navigation, Navionics Dock-to-dock Autorouting, instead, quickly calculates a detailed route, even through narrow passages and channels, based on chart data and navigation aids.

On the Boating app, find points of interest (POIs) nearby the destination, like the harbor master, marinas and moorings, fuel stations, restaurants and bars, shops, taxis & launch services, repairs, and dealers. They appear automatically within the Autorouting menu, complete with phone numbers and other valuable information like VHF channels for marinas.
