from previous announcements, RAM fill is going to allow all of the 4500+ pounds of ballast in a 244 to fill in about 30 seconds. Same with draining.
They also are putting on a CATs system, which is essentially a forward adjustable rudder on the boat.
They also are talking about an 'asymetrical wave plate'. Just looks like my wing plate, with one side hacked off. Not really digging that. They've gone from a simple wake plate, to a wing plate, to now 3/4 wing plate. Not real sure about this one.
