panga keel lines

this is the 35yr old yamaha designed panga keel lines
this builder squared off the transom
the original had an up swept transom..like panga.com pangamarine etc

i am wondering what would be the right design name features of this hull

bump
any names for this keel line?
it is a flatish triangular section/pad starting from the water line of the bow and runs back to the transom
from the flatish center pad which is edged with straits/skegs it is chined
cheers jack

 

my best guess so far is either
a modified v with full length delata pad along the center

or a 3 chine multy chine hull

the chines are constant and the angle doesnt vary along its length

anyone has any input?
