In Spanish, Puerto Vallarta is often shortened to Vallarta, while English speakers call the city P.V. for short. In internet shorthand the city is often referred to as PVR, after the International Air Transport Association airport code for its Gustavo Diaz Ordaz International Airport.

Good nav lights are literally a life saver, I have really good led ones that are visible form 3 nautical miles on mine since I night fish almost exclusivly. Have almost hit several people who didn't have lights on at night.
A steady red light marks the port (left) side of a boat; a steady green light marks the starboard (right). White lights are masthead lights or stern lights on the back of the boat. They make the boat visible at night. A steady yellow light marks the stern (back) of a tug pushing barges. The position of the lights on a boat has significance. Large ships have white lights on two masts. The forward mast light is the lower of the two white lights, making it possible to tell which way a ship is moving. Law. The size, type, color and visibility of a ship's colored lights is dictated by the U.S. Coast Guard Navigation Rules.
