@maritimemaster: Thick fog, pitch black night, and your radar has already found the ship you cannot see. In under 90 seconds: how radio pulses become range, bearing and a live picture of everything around your vessel, why it works when your eyes fail, and the honest limits every skipper should respect (small GRP boats, sea clutter, rain). COLREGs Rule 7 says use it properly, so save this one for your next night passage. #LearnOnTikTok #maritimetraining #maritimemaster #boating #navigation #deckcadet #sailing #seafarer⚓️ #seamanship⚓️🚢⛴️
