SeaArk: Silent Running
By Lenny Rudow
The development of an ultra-quiet boat has anglers and dayboaters excited about stealth.

Correct Craft's Watershed Innovations and the University of Central Florida's Senior Engineering Design Program have partnered to work with SeaArk to develop an ultra-quiet boat. Students intend to apply "computational fluid dynamics" and electric propulsion to this end. A more or less silent boat could have benefits to both people enjoying a day on the water and anglers trying to remain stealthy as they fish.
While electric propulsion is certainly quieter than internal-combustion engines above the waterline, most of the underwater noise created by modern powerplants is generated by propeller whine. From the angling perspective, other attributes of the boat will have to come into play. Chine-slap, for example, is a common complaint among shallow-water anglers who believe strongly in the advantages of a stealthy approach.
For people in the boat, however, silent running is undoubtedly just as important. Luxury carmakers learned long ago that loud noises lower comfort levels. That's why Sea Ray Boats has invested in what it calls "Quiet Ride," a combination of noise-mitigation construction features, including such high-tech advancements as laminating a fabric into the hull which converts vibrations into heat to reduce overall sound levels.
In development for several years and slowly migrated into the model lines, with Quiet Ride Sea Ray was able to cut sound levels on some models in half. In this case, engineering students plan to design, build, and test prototypes over a yearlong period.
"It's exciting to collaborate with UCF students on this project that will help mold the future of fishing-boat technology," says Correct Craft President and CEP Bill Yeargin. "Our vision is not only to improve the marine industry but also to progress in research and development. Partnering with key groups is an important part of Watershed's model and UCF is the nation's top partnership university."
