bolo - boaters on the lookout

Free boating awareness app for hazards, fuel prices, wildlife sightings, and local reports. Simple map-tap updates, not routing or charting.

bolo is a free boating awareness app for real-time hazard reports, marine fuel prices, wildlife sightings, and crowdsourced waterway alerts.

bolo is not a routing, chartplotter, or turn-by-turn navigation app. It is a crowdsourced awareness layer for boaters who want to know what is happening on the water before they get there.

With bolo, boaters can: • Report hazards like floating debris, shoaling, submerged objects, obstructions, crab pots, speed and no-wake zones, closures, and unsafe conditions • Check and share nearby marine fuel prices • Post wildlife sightings, oyster reef observations, and local waterway notes • See community reports around marinas, ramps, harbors, rivers, bays, and coastal waterways • Help other boaters stay aware on the water

What you can report or add a note on:

Hazards: floating debris, submerged objects, shallow water, fixed obstructions, and bridge closures

Underway activity: congestion, crab pots, trap lines, speed and no-wake zones, bridges, locks, buoys, anchor spots, and moorings

Conditions: rough seas, poor visibility, strong winds, strong currents, and changing local conditions

Social: sandbar gatherings, raft-ups, dock parties, and local boating activity

Wildlife: dolphins, manatees, whales, sharks, sea turtles, oyster reefs, and more

Services: fuel prices, marina updates, pump-outs, waterfront restaurants, boating stores, boat rentals, boat ramps, and more

Other boaters can confirm reports or add tips to services. Share a report with a tap, and get push alerts when something is reported nearby.

How it works:

Tap the map to drop a pin or add a location. Your observation is geotagged and visible to nearby boaters.

bolo weighs reports by reporter reputation, so trusted boaters' observations carry more weight.

Features: • Live map with real-time community reports • NOAA weather alerts for your location • Nautical chart overlays with buoys, beacons, bridges, and other marine markers • Confidence scoring as more boaters confirm reports • Reputation levels from Newcomer to Expert • Proximity alerts for nearby hazards • Free to use

Good for: • Recreational boaters • Sailors • Powerboaters • Jet skiers • Anglers • Marina and fuel dock users • Yacht clubs and boating clubs • Harbor and local waterway communities

Situational awareness, not navigation:

bolo does not replace official nautical charts, NOAA publications, Coast Guard resources, AIS, radar, weather, local notices, or safe seamanship. Use bolo alongside your normal navigation and safety tools.
