2021 Highfield Sport 390

This 2021 Highfield Sport 390 is a rigid-hull inflatable built for versatility and rough-water performance. The aluminum hull paired with durable Hypalon tubes creates a stable platform that handles choppy conditions comfortably, while the offshore-oriented design keeps the ride smooth across varying water states. At 12.8 feet, it's compact enough to trailer yet spacious enough for genuine day cruising or fishing.

Power comes from a 2021 Yamaha 50 hp four-stroke engine with roughly 131 hours of running time. The boat cruises at 23+ mph while delivering over 8 mpg—exceptional efficiency for its class. Top speed reaches 34 mph, giving plenty of performance range depending on conditions and load.

Navigation and monitoring are handled by a 9-inch Simrad touchscreen chartplotter with full mapping, side-scan sonar, water temperature readout, and NMEA integration that feeds live engine data and fuel level to the display. Standard equipment includes a Bimini top, full boat cover, sunpad filler cushions, and an 8-gallon fuel tank. The boat comes on a trailer as shown.

The combination of efficient power, proven electronics, and solid build makes this rig equally suited to exploring, fishing, water sports, or casual bay and lake cruising.
