Red Port

The Red Port is one of the two ways to cross the Red Line when traveling on the Grand Line. It was first alluded to by Pappug

Overview
The Red Port is the official, legal way to cross the Red Line, however it is conditioned by approval of the World Government. There seem to be a fee for traveling through he port. Those who are granted the approval, are required to leave their vessel, and to find a new way to travel on the other side.

Layout
So far, only the port on Paradise was seen. It is seemingly build on two Yarukiman Mangrove, which allow the land to have the same properties as Sabaody Archipelago, consisting on occasional bubbles to float in the area. It has several low buildings, with cylinder roofs. On the shore there is a ship's bow, with the World Government symbol under its bowsprit.

The port feature two very large vessels called Bondolas, made of bubbles, and are connected by wires to act as lifts back and forth from Mariejois at the top of the Red Line. They are large and strong enough to fit the very large Shirahoshi and Neptune, as well as several other royalties and their parties.

Locations
There are two ports, one on each side of the Red Line. The Paradise station is located behind G-1 Marine Base (formally Marineford).
