Yes we have and it is fine. One incident inquired as to whether it would be legal with the trolling motor deployed, to which we politely suggested that many would not be legal with the trolling motor deployed, including side marker lights in some cases. Of course most are anchored then requiring the anchor light as they are not underway, which makes them legal. We will say that the rub rail mounted lights some are using are not USCG approved and are not directionally legal. You can easily verify the USCG regulations on their boat builder web site and find that the bow light is within the degree of tolerance as mounted. BCB
