CANALNAV: Canal du Midi GPS

CANALNAV is the first navigation GPS entirely dedicated to the Canal du Midi (UNESCO World Heritage) and the Canal de la Robine — France's iconic southern waterway from Toulouse to the Mediterranean.

Designed for pleasure boaters, hire-boat holidaymakers and professional mariners, CANALNAV offers real-time navigation with automatic alerts for every lock, bridge, aqueduct and spillway on your route.

━━━ KEY FEATURES ━━━

🗺️ REAL-TIME GPS NAVIGATION
Turn-by-turn guidance along 240 km of navigable canals, with map rotation following your boat's heading. Works offline once tiles are cached.

🚦 253 GEOLOCATED STRUCTURES
Automatic alerts as you approach:
- Locks (with operating hours and cycle time)
- Road & foot bridges (with clearance data)
- Canal aqueducts and historic spillways
- Ports, marinas and casual moorings

🏛️ HERITAGE MODULE — 285 photos including vintage postcards
Rediscover the canal through 143 historical postcards (1900-1930) paired with 142 current photos. Compare "then and now" at every structure.

⚓ USER CONTRIBUTIONS
Declare your own moorings (shade, services, star ratings), report obstacles or hazards on the water — instantly visible to other boaters. Community voting keeps information current.

🔍 SMART SEARCH
Find any lock, bridge, town or waypoint. Search by name or by kilometre point (PK).

⛵ BOAT PROFILE MATCHING
Enter your boat's dimensions once: CANALNAV warns you if any structure ahead exceeds your headroom, beam or draft.
