Actually I'd venture to say that you have a semi displacement hull. Thats what I think of our 4788 as.

As you indicated she has a full keel, and soft chines.

I've found that mine even at 15 knots is not realy "over the hump" like our planing hull cruisers were.

I could be wrong, but that seems to fit the definition of "semi displacement" *that boat builders and the public have come to use to define a boat that exceeds hull speed but is not as fast as a "cruiser".

That said, I tend to agree with Beebes definition of boat hulls* being either displacement or planing. Using Voyaging Under Power as a guide we own planing hull boats.

Perhaps a better poll would be " What is the maximum speed of your boat"

The link below is to Bruce Roberts site and is his opinion of the differences between hull forms.
