Fans of the Deep Impact line have eagerly awaited a revamped version of the Miami boatbuilder’s performance-oriented 39-foot center-console ever since Mark Fischer, the owner of Boats Direct USA, bought the assets of the company two years ago. Well, the wait is over as Fischer, along with his key Deep Impact employee Randy Truesdale and several others involved in the project, recently put the new-for-2017 Deep Impact 399 Sport through its first sea-trial.

In it first sea-trial, the quad 400-hp outboard-powered Deep Impact 399 Sport reached an impressive 84.2 mph.

The 39-footer’s original stepped hull was a proven performer that needed no enhancement, and that proved true again when the new boat—powered by quad Mercury Racing Verado 400R outboard engines mounted on Bob’s Machine Shop adjustable jack plates—reached 84.2 MPH during its first test session. In addition to the above-noted full load of passengers, the 16,000-pound carried 100 gallons of fuel.

“Honestly, I would have been in awe to see the boat break the 80 MPH mark—I was expecting 76 to 78 MPH,” said Truesdale. “Mercury Racing is going to come down to help us dial it in even more.”

“It was an impressive first performance,” said Fischer. “The handling, the ride, and the speed were great. I couldn’t believe we were going almost 85 MPH. There was no wind at all behind the console.”

The wind protection afforded to Fischer and the others behind the console that day came courtesy of a windshield built into the 399 Sport’s most attention-grabbing feature—its new gunwale-to-gunwale fiberglass T-top. An internal aluminum frame adds brawn to the fiberglass structure. But that not the top’s most intriguing feature.

One striking feature of the updated 39-footer is its sleek yet substantial T-top.

“With the new top design, we wanted something unique,” said Truesdale. “So we designed an aerodynamic, back-sloping top with a fixed windshield and two ‘panoramic roofs’ that allow for sunlight but don’t scorch you while you’re at the console.”

Of course, Deep Impact added more than a new top to the boat. The new 399 Sport center-console now boasts lounge seating—complete with flip-up armrests—ahead of the console, as well as a fully air-conditioned cabin with a head locker (In the prior model, the entire cabin, which has been expanded, served as a head locker and stowage space.) Deep Impact also reconfigured the boat’s helm station with a large dash that holds two Garmin 8617 displays and two smaller Garmin units, all networked via NMEA 2000 technology for total touch-screen operation, and new fold-down/leaning post seating.

In a less obvious but decidedly more practical move, Deep Impact eliminated the generator from the earlier 39-footer and replaced it with 110-volt power through an inverter system with four additional batteries.

Although most 399 Sport models will come with triple or quad Verado 400R outboards, the next one will be powered by a trio of 350 HP Yamaha F350C outboards and be used as a yacht tender. Hull No. 4 will be a “cabin boat” with a full cabin all the way forward and a head locker in the console.

Next in line for updating is the company’s 36-footer, called the 360 Super Sport. According to Truesdale, that model only will be offered with triple outboards.

But that’s a bit down the line for Deep Impact. Right now, everyone involved is thrilled with the release of their new 39-foot beauty, which will make its boat show debut at the 2016 Fort Lauderdale event, then join the Florida Powerboat Club’s Key West Poker Run and go on display at the docks behind the Conch Republic restaurant near the FPC’s Poker Run Village. After that, the new model’s 2017 tour will begin with the Miami International Boat Show in February.

“We’re really happy with the finished product,” said Truesdale. “And we’re looking forward to showing it off.”
