Pretty sure they went to composite coring in the 2005 models. I have a Msg in to the factory. I will update then. These 4-piece hulls are super stiff and very light.
I have owned two of them.. The DV model was discontinued when the Cobia line came to the Ft. Pierce factory. I have the last one they built. 2011
I gave Capt. Dave my cell phone to go into specifics.
There are many DVs in the Keys, and they are at home from offshore to The Park. Scuba tanks fit in the fishboxes and the two deck lockers. We flyfish off the bow for Mahi.
Nothing like it made since. Only point of note is the low bow. In snotty inlets, you have to be careful to keep the bow up so you don't take the crests over the bow.
