Are you seeing that in the harbor Sniper450? Or out sailing on the ocean blue? Are you up in Uchiura Bay, or out further? Tsugaru Straits? Have you got a lat/long position, or mileage or something? The time frame is in the 41a layer, and there are some issues with the layer files due to the RGG having mostly 19380101 start dates for the ships. Hopefully, the next update will eliminate this issue...
