302 Waterways

302 Waterways is the community-powered navigation app for the East Coast, from Maine to Florida. It was born on Delaware's Indian River, Rehoboth and Assawoman bays, and now covers every Atlantic state: the Gulf of Maine, Cape Cod and Long Island Sound, the Jersey Shore, the Delaware Bay and River, the Chesapeake, the Outer Banks, the Lowcountry and Florida's Atlantic coast. See what local boaters know, in real time: shifting sandbars, shoaling, hazards, no-wake areas, and the routes people actually run — all on a live chart with NOAA nautical charts and high-resolution satellite imagery. WHAT YOU GET • Live map — NOAA charts + satellite, channel markers, depth, marinas, fuel docks, and public boat ramps • Public ramps and marinas you can actually use — from each state's official public water-access data, leaving out resident-only, permit, members-only and private sites • 3D (Plus) — see the water the way it really looks, with NOAA's high-resolution depths underneath; explore, plan a trip and cruise in 3D • Trip planner — pick where you start and where you're going from ramps, marinas and your saved spots (set a home marina or ramp for one-tap trips), or draw the route with a finger; it stays on the water • Directions for your boat (Plus) — pick where you're going and get the recommended way: into the marked channels and along them, in the deepest water at the tide you'll meet, through the bays rather than the ocean when there's a way inside • Safe Route (Plus) — the deepest way for your boat's draft at the tide you'll meet, clear of reported hazards and sandbars • Apple CarPlay — the chart and turn-by-turn boat directions on the CarPlay screen, with spoken turns in port and starboard or compass headings; 3D with Plus • Your chartplotter — send any route or recorded trip to your Garmin, Lowrance, Simrad, B&G or Raymarine plotter, or Navionics, as a GPX file, and bring your plotter's routes, tracks and waypoints in • Bridge clearances — the room under every bridge and power line, at today's tide, and whether your boat fits • Military and restricted waters — Navy, Marine Corps, Army and Air Force ranges, naval bases and the Coast Guard's security zones, each with what it means for you: keep out, closed only while active, transit only or slow down • Emergency — the Coast Guard, marine police and towing for the waters you're on, with your position ready to read out on VHF 16 • Community reports — sandbars, shoaling, debris, hazards, no-wake areas, and wildlife sightings, confirmed by other boaters • Cruise mode — a heading-up, follow-along navigation view with your speed and course, that auto-zooms with your speed and calls out hazards and no-wake zones ahead • Routes — record your track by GPS and share the line so others can follow it • Conditions — tides from more than 1,500 NOAA stations, wind, and weather at a glance, and an hour-by-hour chop forecast for each bay (Plus) • Friends — connect with other boaters and see the routes they share with you • Mark an area — draw a caution area to warn the community Built by boaters, for our waters. Free to use. 302 Waterways Plus, a monthly or yearly subscription, adds boat directions, Safe Route, 3D and 3D Cruise, route alerts, the bay chop forecast and 3D trip videos. IMPORTANT: 302 Waterways is community intelligence — not a certified nautical chart and not a replacement for official charts, a dedicated GPS chartplotter, or safe seamanship. Conditions change; always navigate responsibly and carry required safety equipment.
