Marine VHF channels are essential for communication on the water, and knowing which ones to use can make all the difference in safety and efficiency. The primary channels for general communication include Channel 16 (156.800 MHz), which is the international distress, safety, and calling frequency, and Channel 13 (156.650 MHz), primarily used for bridge-to-bridge communication. For routine communications, you can use channels 68, 69, 70, 71, 72, and 78, which are designated for recreational boaters. Always remember to monitor Channel 16 when you're not actively communicating, as it's crucial for receiving emergency calls and alerts from other vessels.
