ICW Planner turns a day on the Intracoastal Waterway into a clear timeline: when each bridge opens, how fast to run each leg, and what the tide and current are doing when you get there — from Norfolk (MM 0) to Miami and the upper Keys gateway.

Built on official data — NOAA tides & currents, USCG notices, and 33 CFR bridge regulations — and designed to keep working when the signal doesn't.
Arrival time at every bridge on your route, cross-referenced against its real opening schedule and restricted-hour closures. Free.
Per-leg speed recommendations so you arrive right as the bridge opens — less waiting, less throttle-jockeying. See how total wait changes across a band of cruise speeds.
Tide-adjusted vertical clearance at fixed bridges, plus tidal-current timing that turns speed-through-water into real speed-over-ground.
Will you fit under it — and float over it? Tide-adjusted air-draft and grounding/shoaling advisories at your ETA.
USCG Notices to Mariners filtered to your mile range, with per-bridge alerts for outages and schedule changes.
The ICW magenta line with status-colored bridge pins, tide graphs, and a tap-through detail view for every crossing.
Speed-limit / no-wake / manatee zones, overhead cable & pipeline clearances, and lock-passage beam advisories.
Optional location-based heads-up when you enter a speed or no-wake zone while you're moving.
Save your trips, and plan around sunrise, sunset, and nautical twilight computed on-device.
