Water-aware planning over official NOAA ENC geometry — land, charted depths, dredged channels, hazards, restrictions and bridge clearances constrain the path; an independent validator then checks every segment. Results are experimental proposals, never approved routes.

Long-press the chart to drop a waypoint there.

Vessel profiles live on this device only — nothing is uploaded or tracked.

Units apply to SlipLanding readouts; sounding numbers printed inside NOAA chart tiles are meters (official chart convention).
