Dream, Test, Repeat
Hundreds of hours have already been logged CAD testing and simulating the boat’s performance among Jarrett Bay’s inhouse design team of Gary Davis, Chad Vorhees and Brandon Davis along with input from a select group of specialists, such as scientists at Materials Science Corporation and Maritime Research Associates. The team then turned to the MARIN Research Institute Netherlands for real-world validation. Jarrett Bay President Randy Ramsey explains, “We’ve worked with MARIN before and they can perform large tank and high speed testing comparable to the U.S. Navy’s proprietary tanks.” Gary Davis explains how a 12’ model of the hull was constructed and tested in what would amount to 9 to 12 foot seas by MARIN this past Spring; conducting three rounds of testing in all so far. “Everything we thought about our design was confirmed, the deflection of the hull, how it moved and behaved, it was all captured with slow motion photography. We could not have been more pleased with how it performed in every sea state.” The second round of testing included operating the model by remote control with full running gear; testing the design of propellers, rudders and struts while simulating performance in tight turns and maneuvers. “It performed flawlessly, even beyond expectations. There were people at MARIN vying for a chance to drive the model each day,” Ramsey adds.
“It’s going to change the way boats are built… and set new boundaries in speed, performance, reliability and safety.”
Getting It Done
Ramsey praised Riggs’ work ethic throughout the build process thus far, acting as an everyday advocate on behalf of both the owner and builder, explaining, “He’s a pleasure to work with. He’s been visiting the facility each week, sometimes for more than a day.” In these visits, Riggs views the 90’s progress first-hand and monitors that everything is on track with the various major milestones and timelines for the owner. The pair of massive 2,600 horsepower MTU engines and a pair of 40kw generators will soon be delivered and everyone is looking forward to starting on the cabin house. Riggs appreciates the professionalism and teamwork he’s experienced at Jarrett Bay, saying, “They are a great group of guys to work with. They have a passion for what they do and it shows from initial engineering on down to the wood workers who are building the boat.”
