According to this site, “25W is the highest available (about 3.7- to 29-mile range),” but 3 to 5 Watt radios are more common and generally transmit a shorter distance (less than a mile).On the Other: Using a VHF Radio On LandRegardless of distance, according to Sailing Center, “You must not transmit … when your ship is on land (for example, while the ship is on a trailer).” Thus, communication can only be received while on land.
