Haig Point Transportation, located on picturesque Daufuskie Island, SC, has asked DLBA to assist with a repower of the 55’ (17m) HAIG POINT IV vessel in their ferry fleet. DLBA has previously provided similar services for the HAIG POINT II vessel. All necessary driveline calculation and machinery arrangement tasks will be performed to perfectly match the chosen twin Volvo Penta D13-500 diesel engines with the existing hullform.
Designed in 2006 by Timothy Graul Marine Design of Sturgeon Bay, Wisconsin, HAIG POINT IV currently uses twin Cummins QSM11 engines mated to Twin Disc MGX gears to ferry passenger from locations on Hilton Head Island to Haig Point Landing.
Vessel repowers need to be handled carefully. Changes in weight, particular on smaller vessels can have a dramatic effect on overall performance and can impact USCG stability letters – so it’s important to get it right! DLBA will start the process by establishing a performance baseline of the existing propulsion setup. New engines will then be positioned to ensure proper integration with the hull structure and engine support systems. Every part from the engines to the propeller nuts will be analyzed and tuned to work together as a cohesive system. With the right planning and execution, the final product will be well-suited to its counterpart systems and the needs of the vessel.
