“Comparative Analysis of Common Methods for Predicting Vertical Acceleration of Hard Chine Planing Monohulls including Correlation to Hydrodynamic Model Test Data”

We talk a lot about going fast here at DLBA.  Speed is exhilarating, right?  Well, we have to remember that it is not the end-all be-all requirement for water borne craft.  There is a little thing called seakeeping, and in its realm, size does matter! Passengers want an enjoyable, comfortable ride – not one filled with large motions and jarring accelerations.  The bigger the boat, the softer the ride, but often times you can’t just make the boat bigger.

Norfolk Dredging Company (NDC)-160

DLBA has once again been selected by NDC of Chesapeake, VA to support them, this time for performing a stability test for the crane barge NDC-160 for the U.S. Coast Guard Certificate of Inspection (COI).  This will be the third vessel in the NDC fleet that DLBA has conducted regulatory stability testing for over the past year.

Ritchie Howell 63

Ritchie Howell is a well-known builder in Wanchese, NC.  DLBA and Ritchie are developing their next collaboration for a current owner who wants a slightly larger boat.  The new 63’ will be a flybridge layout showing off sleek topside shape capturing style consistent with the Ritchie Howell heritage. The hull will be cold molded with Douglas fir bottom stringers providing efficient, but robust reinforcement.  Decks will be of composite fabrication resulting in stiff, but light structure up high.

Artificial Intelligence (AI) Enabled Marine Camera System

At DLBA, it is our privilege and our pleasure to stay on top of the latest trends and technologies and be in a league with others who are doing the same. We are performing for DARPA on the No Manning Required Ship (NOMARS) program to look into the future and explore what capabilities can be achieved with a vessel designed without the ability to carry crew or guests on board.

Electric Maneuvering and Drive Systems for Advanced Craft

Our Thoughts on this Paper
A planing vessel is a high-performance vehicle.  A high-performance vehicle is a vehicle where dynamic forces acting on the vehicle exceed the static forces.  For planing hulls, dynamic lift from pressure on the hull bottom provide more vertical force than the buoyant force of water.
