Deep Impact 399 Open

Tournament center console or family entertainment platform

FIRST IMPRESSION: There's nothing subtle about the Monster Energy Team's 399 Open from Deep Impact that I tested during the 2012 Miami International Boat Show. From the big, triple Mercury 300 Verado outboards to the screaming vinyl hull graphics, this boat is amped up to go big-water fishing, as if fueled by its sponsor's caffeinated energy drink.

TARGET MARKET: Here's a 39-foot center console than can compete at the highest level in the Southern Kingfish Association (SKA) tournament circuit, but is also well suited for kite-fishing or working wrecks and oil rigs. The Deep Impact 399 Open is a good fit for the angler who wants the ultimate in a go-fast fishing boat that can also serve as an entertainment platform for family and friends.

FISHIEST FEATURES: The 399 virtually flew across the water. Buried throttles produced a top speed of nearly 66 mph, which should get you to the fish fast. The boat also featured twin, 55-gallon livewells with clear-acrylic lids built into the full transom. Twin alcoves at the helm hosted a pair of 15.5-inch flush-mounted multifunction displays. You'll find tackle storage and rod holders in the seat-back pod. Coaming pads surrounding the cockpit cushion your legs while you fight a fish. The elevated foredeck is a useful feature, but be careful — freeboard in the bow is minimal.

THE LAYOUT: Deep Impact builds only custom boats on order. A hull reinforced with resin-infused coring and several layers of Kevlar means the 399 can take big seas in stride. Three-across, racing-helm seats with drop-down bolsters offer extra security when running fast. Housed inside the console is a marine privy with 7 feet of headroom. The level of fit and finish is impeccable.

FINAL WORD: The 399's multi-step hull creates a cushion of air under the running surface to reduce drag. This, combined with 24 degrees of deadrise at the transom, allowed it to easily bridge four-foot wind waves and never pound in my test. At the same time, it is a stable and comfortable fishing platform at rest, with all of the features you need to best any tournament rival.
