In the Mediterranean, it respects the boundaries of Marine Protected Areas (MPAs) and fish farms. The algorithm in v3.1 is notably more conservative than v2.0, making it safer for monohull sailboats with deeper drafts. In the world of digital maritime navigation, few
While modern Navionics uses cloud-based "Community Edits," v3.1 used a physical SD card system. However, it still allowed users to mark new hazards (like a shifting sandbar or a new wreck) directly on the card for their own future use.
