The technology being used is going to go across the entire gambit, because we get some very old ships that are still safe and still meet all the requirements and transportation regulations, but they are not as technically advanced as some of Donna's cruise ships.
With respect to the noise, it will vary significantly from ship type to ship type. The cruise ships, as an example, have a lot of Azipod vessels. They are electrical and have smaller engines producing electricity that powers a podded system. It's much quieter than an older bulk carrier, with a very large single-propeller engine, coming in to pick up grain.
It will vary. Right now, there is a voluntary study going on in the Haro Strait area and the Georgia Strait where these things are being measured.
All of the industry has been participating at very high percentages to try to get a true sense of what we are dealing with.
