This mod adds seaplane docks to a couple of default airports and seaplane bases in Alaska and British Columbia. Usually the default seaplane airports come without parking spots unlike land airports. Now you can start cold and dark in some of these places, too. I have not added any scenery objects, just the designated areas. Some of them are shown as being on land on the game map before you start the flight but I checked and you actually spawn on water.
The following airports and seaplane bases are included:

CAV5
A23
CAQ3
