Height limits for boat transport depend on the route and type of boat. In general, 16.4ft (5m) is the maximum safe height, as most motorway bridges are at least this high. If your boat is wider than 9.5ft (2.9m), your movers may have to inform the Police force about the boat transport details. The Police may delay moving times to ensure road safety. Further, telling authorities ensures that you don’t encounter problems during transport. Full loads may also need an escort vehicle.
