⚓ PROJECT COMPLETE: Grady-White 330 Express ⚓

When the owner came to us, he had one ask: build out an electronics and comfort package that could handle serious offshore days without sacrificing the fun.

How it all comes together: the GPSMAP 8616xsv is the command center, pulling in live sonar from three transducers so he never guesses where the fish are holding. The Fantom radar spots weather and traffic well before it's visible to the eye, while the GXM antenna streams SiriusXM marine weather straight to the chartplotter — so there are no surprises out past sight of land. The Garmin and NMEA network gear tie every sensor into one clean system instead of a tangle of standalone units. Starlink keeps him connected miles offshore, and the SIONYX night vision camera means low-light running doesn't mean flying blind. Add the Lumitec Razor light bars, and this Grady-White is just as capable pulling into the dock after dark as it is running offshore at sunrise.

Another owner's vision, fully realized. Congrats to Doug on the new setup — see you out there! 🌊
