A real game-changer came several years back when Jarrett Bay teamed up with MTU on its 4000 Series diesel engines. “We learned a lot with that experience — not only working with big power, but with running gear and fuel placement as well,” Davis says. “The result on our hull designs was a minor tweak here and there, and we found we were exactly right with deadrise, water flow, performance and efficiency. While each boat is different, from our 50-footers to our 70-footers, it enabled us to be more consistent from boat to boat,” notes Davis. “With this new 90-footer we’re building, the owner wants to go as fast as he can, and with the current big engines just about maxed out, we’ll be working with what we have to deliver a boat that can not only handle any sea condition, but also move through the water as efficiently as possible,” he added.
