Deep Impact 399 FS/TE (2012-)
Since 1998 Deep Impact has been churning out highly customized boats that are designed to not only meet the rigors of offshore use, but demanding customers as well. With stepped hulls reinforced with Kevlar, these boats are also designed to get to the action first. Powered by triple 6-cylinder Mercury Verado 350's the 399 can reach speeds in excess of 72 mph.

Deep Impact 399 FS/TE (2012-) Captain's Report

Captain's Report by Capt. Steve

Deep Impact 399

There are enough amenities on the Deep Impact 399 to keep everyone happy, even if you're not fishing.

Mission

The 399 was, for Deep Impact, a natural evolution of the popular 36' (11 m) center console. It maintains the company's reputation for delivering the same quality of build and customization that Deep Impact is so well known for.

Distinguishing Features

While the 399 is impressive in its own right, she does bring some distinguishing features to the table over other boats in class. Here are the ones that caught my eye--

• The console, with its 6'10" (2.08 m) of headroom inside has a full head with sink and shower accessed by a sliding door to the side.

• The helm seat had three across seating with drop-out bolsters and integrated tackle storage.

• The Jump seat has retractable armrests.

• Decking is a crown, rather than gutter design to channel water overboard.

• Gutters for hatches are under the deck so they are not seen. Any water gets channeled back to the next gutter until exiting at the engine cut-outs. This eliminates the use of thru hulls in the topsides and streaks. Further, there are no floor gutters to stub your toes on.

• Macerators pump out through the engine cut-outs as well eliminating some thru-hull fittings.

In a slight turn, you can see the double steps in the hull which inject air under the hull to reduce surface resistance.

Performance

While we haven't tested the 399 to verify the claims, Deep Impact does have performance numbers that they've shared with us. With the boat powered by the new Mercury Verado 350 engines, the 399 reached a top speed of 72.4 mph at 6200 rpm. At that speed she was burning 100.2 gph which translates to .72 mpg and a range of 312 miles at top speed.

Best cruise was measured by the builder at 3000 rpm and 30 mph. At that speed the Verados were drinking only 22.8 gph for 1.32 mpg and a range of 568 statute miles. But let's face facts… nobody's gonna be buying a boat like the 399 to be doing 30 miles an hour. Advance the throttles to 4500 rpm and you'll be cruising at 50.5 mph with an endurance of 472 statute miles. That's just over 9 hours of running at an impressive speed. It's not hard to imagine the places that you can go.

Deep Impact 399

The stepped hull has variable deadrise and varying lifting strakes as the hull moves aft. Transom deadrise is 24 degrees.

Construction

The 399 has a dry weight of 13,800 lbs (6260 kg) which definitely puts her in the heavyweight class, and that is a direct reflection of the build quality that goes into the hull. Even without the engines, the hull weight is just under 11,800 lbs (5352 kg). All of Deep Impact's hulls are reinforced with resin infused coring. The hull sides are cored with Mantex and Airex. Transoms are over 5'' thick, and are cored with 24-lb. Mantex foam. Using a no-wood construction technique the longevity of deep impact boats is self-evident.

But of course it takes more than a thick hull to maintain the rigors of continual punishment from high-speed offshore use. The CNC cut foam stringer system is bonded to the hull to further the build strength. To add even more integrity, the floor boxes are inserted and then glassed into place, making them integral structural components.

Layout

Deep Impact 399

The layout of the 399 shows the center console is right at the center of the boat, in the handling sweet spot. Notice the four large deck boxes that are also adding to the boat's strength.

Helm

With boats in this class I always seem to have a problem with visibility since so many builders fabricate such a high console in order to get the headroom needed below. Here, the height is comfortable enough for even short captains such as me (I'm 5'8.5"/1.73 m), to have a clear view of the bow, and beyond. So I am pleased.

The captain gets a center spot in the three-across seats, and these seats wrap around the occupants for sustained high-speed operation. For standing, the bolsters drop down, further enhancing the wrapping effect of the seats. With your kneees slightly bent, your spinal column is protected.

Instruments. The console is beautifully laid out and again, high-speed operations are the key factor to the layout. The captain is intended to spend his/her time looking ahead, as one does at 70+ mph (113 kph). For that reason, the only gauges in front of the helm are the SmartCraft Vessel View, fuel gauges, and the compass.

With the dual observers adding a hand in the navigation, twin Garmin 5215 touch screens are to either side of the panel so the workload can be divided up quite nicely between the 3D chart plotter, radar, bottom topography readouts, satellite weather service, and probably even a partridge in a pear tree.

All switches are to the port side and are waterproof with indicator lights just above allowing a glance to show which is activated.

Battery switches. Four switches, however, stand out to the upper left for the port, center, starboard, and house batteries. This is undoubtedly a unique feature that allows quick activation of the batteries and I'm on the fence as to whether I like it or not. On one hand, I really hate when I have to go on an Indiana Jones-type quest for the battery switches and find them under some remote cushion… far out of reach, but they're usually in such a position so some numb-nut doesn't come onboard and activate your batteries and run them down on you.

The requisite console cover should alleviate that concern, and the fact that you still need ignition keys means that turning on the electrical supply does not equate to a ne'er-do-well being able to start, and therefore take off with, your 399. All switches, gauges, and nav screens are mounted to carbon fiber panels that look great against the white console.

Deep Impact 399

Everything a proper panel should be. Notice the dual controls for each engine and also how the powder coated supports for the hardtop have handholds built in. My favorite feature… a single lanyard kill switch for all three engines.

Aft Cockpit

The first item of business in an offshore fishing boat is the need for handholds, and on the 399 they're seemingly everywhere. Two large coffin boxes are integrally built into the deck and serve as structural components. Macerators feed debris from the boxes overboard through a thru-hull fitting in the engine cutout.

At the transom is the usual rumble seat, but I use the term "usual" loosely, as this one accommodates three-across seating, armrests, and drink holders. When stowed it lies flat against the transom allowing you to fish right to the stern of the boat.

Deep Impact 399

Overhead, the well laid out hardtop features 7 rocket launchers, two skylights, a pair of outriggers, spreader lights fore and aft, and an electronics box for the stereo, VHF, and a remote spotlight control.

Deep Impact 399

An aft facing seat has tackle storage in the seat back, and it also wraps around the occupants much like the helm seats do. The seat is a Frigid Rigid cooler lying over the battery compartment.

Deep Impact 399

The rumble seat stows flush to allow for increased cockpit space when not in use. A stainless gate to starboard allows for boarding from the swim platform. Two hatches to the top of the transom house a livewell, and vertical storage for fenders. Want two livewells? No problem.

Forward

A sliding door to the starboard side of the console allows for accessing the rather large head compartment without impeding the walk space between the console and the bulwarks. The head is nicely equipped with 6'10" (2.08 m) of headroom, a porcelain toilet, ss sink and a shower. Natural light enters from a skylight overhead, just forward of the windshield.

Forward of the console are two individual seats, again with the generous wrap-around demanded in high speed operations.

U-shaped seats are forward and easily convert to chaise recliners.

At the forward end of the hardtop are LED spreader lights and a remote spotlight on top.

It's hard to think of a head compartment as being good looking but here it is. You've got to love the logo work.

Deep Impact 399

Forward is a generous space provided by carrying the wide beam fully forward. Notice the sub-woofer speaker next to the standard speaker. Dry storage is under all seats and a large insulated box is in the deck.

Observations

One of the benefits of purchasing a Deep Impact 399 is the ability to customize the boat any way you'd like. Deep Impact does not, and doesn't intend to, make their boat in a production-style format. For that reason, you simply will not find any two DI boats that are the same.

The test boat was built for a client that wanted to have all the requisite fishing features, yet with extensive seating and family amenities as well. It is important to understand that the photos of the test boat are not the “only” deck configuration possible. DI offers a bow seating delete for the demanding angler that benefits from additional deck floor space, and a livewell delete for those that would rather have more transom seating without livewells. That delete can be coupled with a starboard side “L” seat module as well.

Max hp for the 399 is quad 350SCis from Mercury Racing. The test boat is shown with the triple 350 Mercury Racing Verado's and with that power the boat carries a base price of $405,955. If you want to dial it back a bit, you can power with triple 300-hp Verado's and you'll be looking at a base of $369,955. Either way, you'll be in a boat that is sure to turn heads, even if you enter the high profile offshore tournament realm.
