Hi Andy,
I could start by telling you to just practice taxiing the float plane in FSX, but I won’t.
There are some manuals to explain how things work. Some are probably in your Ship Simulator installation folder in PDF form. Others can be found here:

http://www.shipsim.com/ShipSimForum/index.php/topic,4509.0.html (http://www.shipsim.com/ShipSimForum/index.php/topic,4509.0.html)
You can download info.pdf and the mission editor tutorial from here:
http://www.shipsim.com/ShipSimForum/index.php/topic,2886.0.html (http://www.shipsim.com/ShipSimForum/index.php/topic,2886.0.html)
The ME tutorial gives an explanation of how mission waypoints work, and other useful information. It is worth studying even if you don’t intend to make your own missions.
You can always ask specific questions in either the Technical Support section or the Missions section, as appropriate. You can send me a PM with any question,
Regards,
Marty
