I thought that a centerboard has to be in the center of the boat/vessel.
Now the daggerboards in my P-19 are not located in the center of the boat .... as niether are the boards in my H-18, so I call them daggerboards. Can you imagine the confusion when you tell a first time sailer to "pick-up the centerboard" and point to the edge of the boat ....
So MY definition is centerboards are located in/on the centerline of the vessel, daggerboards can be/are located else where on the boat then on the centerline of the vessel.

Of course this is my personal opiniun.
