the best coastal Auto routing app

Ditch integrates AIS and AI technology to elevate your boat navigation experience.

“Where they stand out is the use of AI to calculate the best route; their AI companion can calculate and choose the best route given their vessel’s length and draft.”

“Ditch is an AI-powered navigation aid that shows boaters the real tracks of previous boaters and color codes them by verified Local Knowledge paths to recommend the Smart Path.”

local knowledge

Traditional plotters and apps all work the same way: They create a route based on the depth soundings charts. Ditch approaches navigation differently, by identifying the routes taken by captains with local knowledge.

Depth sounding

Our high-definition coloring enhances visibility, making it easier for boaters to interpret the charts and plan their routes . In addition to NOAA depth sounding contours, Ditch includes the U.S. Army Corps of engineers survey data (where available) at no extra cost.

filter to your preference

Routes created can be filtered based on boat size, age, and other factors that matter to you. Routes made by captains that you like to follow can be quickly identified with color.

SATELLITE view mode

Boaters can utilize this mode to identify landmarks, coastal features, and navigational aids with unprecedented clarity.

Ditch is the only boat application to use statistical models to analyze historical route data and generate an optimal route based on travel data patterns. This technology is Patent Pending.

how to use ditch

annual subscription



The mobile version of Ditch is free to you for a 30 day trial period. After that, you will be able to unlock all of Ditch’s features for $30/year. The web version of Ditch is always free to use.

  • Ditch is available on both mobile and web platforms, so you can use it on any Android or Apple phone or tablet, and use it free on the web.

  • Probably not. While boaters increasingly rely on phones and tablets for wind, weather, dockage, music, navigation and other features there are still proprietary protocols for sonar and radar. However, Ditch routes can be uploaded to a chart plotter in GPX format (and vice versa: routes created by other systems can be imported into Ditch).

  • Ditch is designed for segments that have been frequented by boaters with AIS transmitters. If you're not getting results try creating a shorter route and then select one of the red waypoint targets and select 'Extend Route' to build a longer path.

  • These depth areas represent U.S. Army Corps of Engineers survey data going back to 2020. You can view a key of depths by toggling ‘Show Legend’ under settings.
