2019 Grady-White Canyon 456 “NATILUS II”

NATILUS II represents an exceptional opportunity to acquire Grady-White’s flagship center console yacht, meticulously maintained by a full-time captain with a true "open-checkbook" philosophy since new. Powered by Quad Yamaha 425 HP XTO Offshore V8 engines, this 45-foot luxury vessel delivers unprecedented offshore soft-riding performance built on Grady-White’s award-winning SeaV2® hull design. Every single maintenance record, routine engine service, and equipment invoice (managed directly by the captain) is fully documented and available for serious buyers upon request.

Designed to bridge the gap between a hardcore tournament-ready fishing machine and a luxurious weekend cruiser, NATILUS II is loaded with top-tier optional equipment and modern upgrades. Key highlights include a Seakeeper 6 gyro stabilizer, a Mase 15.5 kW diesel generator, a SIONYX night vision camera, a GMR 624 open-array radar, Reactor 40 autopilot, a brand-new bow thruster setup, and carbon fiber outriggers. For the ultimate fishing advantage, an additional flush-mounted Garmin display is installed directly in the aft cockpit facing the mezzanine, allowing the captain and crew to monitor sonar and charts right from the cockpit.

Notable recent updates and high-value maintenance items completed on board include brand-new battery chargers, new galvanic isolator, new onboard device grounding, warranty-replaced Garmin displays, full generator overhaul, and complete 1,000-hour engine services. NATILUS II is turnkey, fully detailed, and ready for immediate delivery in South Florida.
