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.
Making the world better, one answer at a time. Lights are always required to be installed on a boat trailer. This is so no one runs into the back of the trailer, especially at night.he size required is determined by the 'hitch' on the trailer or device being towed. 1-7/8 and 2 inch balls are common sizes.     You may also need a T-One adaptor to hook up the trailer lighting.
