If the problems need review, a resolution is introduced in Congress and a study is authorized of the particular channel. On the study's completion, the recommended changes would be made. One of the problems, I would imagine, with port design is that you have to design the port so that many different types and sizes of ships can come through it. I was wondering whether you have any insight into the most demanding types of ships that you have to drive through the New York harbor. Some of the larger ships, passenger ships, are quite easy.
Loaded tankers are difficult ships to handle because of their size and weight.
The SL-7s, because of their size and handling abilities, are very difficult ships. The most difficult part of the SL-7 pilotage in the New York harbor is done by the docking masters and not by the sea pilots. One cliff iculty in piloting an SL-7 is that the wheelhouse is all the way forward. The pilot therefore has lost a lot of his perspective, being right on the bow. He doesn't get a feeling of the ship's mass, and he can't see just what the ship is doing, so the pilot usually doesn't stand there, but prefers to stand more or less in the midship house where some of the stacks are.
