Whether you're looking for a tender worthy of the most sophisticated mother-ship or you just want to run the coolest head-turning, state-of-the-art boat out on the water, you'll want to check out Deep Impact's new 399 Cabin Center Console—which is just what we did, during the recent “launch” party in Deep Impact’s new factory. Another benefit of seeing it on dry land first was the ability to get up close and personal with the cutting-edge 24.5-degree hull, without having to use scuba gear.

Twin steps and high-tech construction make the Deep Impact 399's hull one of a kind.

The manufacturer reports that these hulls are reinforced with resin infused coring, with hullsides cored with Mantex and Divinicel, then further reinforced with layers of bullet-proof Kevlar. Beginning with the 399 Series in mid-2013, Deep Impact started utilizing a resin infusion system for all fiberglass components to build parts that are lighter, stronger and more consistent, further improving upon their already highly-respected construction.

Va-va-vroom! This Deep Impact sports quads, and reports a top-end of about 80 mph.

The model on display was powered by four, yes four, Mercury 350 Verado engines with the cowlings painted to match the masculine gunmetal gray and black hull. While we weren't able to test it ourselves at the time, rumor had it that the burly quads will take the boat over 80 mph. A few weeks after its debut, the manufacturer began initial sea trials proving those estimates, reaching an impressive 78 mph on day-one without fine-tuning. This is not surprising when one takes into account that the Deep Impact engine rigging team are top professionals who have years of experience on championship offshore racing boats.

"For our first time out the boat was impressive, especially considering it's a cabin boat," said Randy Truesdale, Deep Impact Sales & Technology Consultant. "It's a very solid boat that is loaded with a slew of creature comforts inside. Overall the ride is amazing and it jumps right up on plane, too. Mercury is going to be down here soon to some more dialing in, so we are very confident we'll see a top speed in excess of 80 mph."

This is due in no small part to the company's proprietary computer generated multi-step hull. The goal of which was to not only go fast, but also to attain top speeds comfortably and predictably. The manufacturer reports that this inventive engineering also "produces 20 percent more speed and miles per gallon."

Shortly after the launch party Deep Impact began real-world, on-the-water testing of the 399.

The design builds upon the company's successful 399 Open, which was launched in 2012, and adds a whole new level of versatility to that proven design. The most noticeable difference, but of course, is the cabin—which is more expansive and airy than one would expect of a Bimini cuddy on a boat with a LOA just under 40'. One design feature that makes the cabin genuinely larger than it would be on a comparable vessel is the fact that the enclosed head is placed inside the over-sized center console, just as on the 399 Open.

The cabin's interior fit and finish are seamless, starting with the twin lounges that are a pleasure to use while enjoying movies on the flatscreen television, taking a quick nap, or tucking in the passengers when you're running through heavy weather. There is also a well-laid out galley complete with microwave, cooktop, refrigerator, and freshwater sink, with ample ventilation via dual windows that further enhance the spacious feel.

Few center console boats can boast the kind of room and amenities you'll find on the 399.

The topside starts off with the same generously sized deck of the Open for easy maneuverability aboard. BoganTec Marine USA provided the upscale non-skid decking and flooring found throughout. The center console has also been enhanced, with a larger T-top that shades a console—which looks like something off the starship Enterprise, and probably provides more data than William Shatner would ever be able to comprehend. Garmin and JL Audio equipment highlight the premium instrument package.

Though the 399 Cabin Center Console may seem just right as is, as evidenced by the three orders placed during the launch party, Deep Impact remains a semi-custom builder.

"We have something for everybody in order to fulfill their unique needs, and that’s one of the keys to our success," stated Truesdale. "There are different deck layouts, engine selection, color choices, the overall look and feel, plus fishing or cabin options, giving us the ability to personalize our boats, which is a major reason our customers keep coming back and we're attracting new clients.”

Other choices: The Hydra-Sports 4200 is another brawny beast that can take either triples or quads on the transom; expect more emphasis on fishing, and less on speed. The Concept 4400 is another choice with a Bimini cuddy in the bow. And you might want to check out the Nor-Tech 3900, which is another semi-custom center console go-fast rig.

Rumor Alert: We've also heard quiet whispers that there may be a 42' model on the drawing board.
