Two boats, one hull, and two model pages that say almost exactly the same thing. Scout's 670 LXF and 670 LXS are both 66'9", both on a 16'2" beam, both carrying 1,500 gallons of fuel, both offered with four or five Mercury V-12 600s, and both rated to 3,000 horsepower. If you are trying to work out which one you want from the website, you will not get there by counting engines. The document that separates them is Scout's own LX Series flyer, and it does the job in one line.
One line separates the two 670s
On the flyer's optional-equipment page, under a heading called Model Selection, there are two choices. Sport version: no upper station. Fishing version: includes flybridge.
That is it. LXS is Sport. LXF is Fish. Scout's LXF model page makes the same point in prose, calling it the ultimate fishing version within the 67 LX Series, complete with an incredible upper station flybridge for the discerning offshore fisherman.
Both boats were designed in partnership with the superyacht design studio Harrison Eidsgaard, and Scout describes the 670 as one of the largest outboard-powered sportfishing yachts built in the world. At 66 feet 9 inches, it is the longest model Scout lists.
The numbers, as Scout publishes them
Scout's model page states that the 670 LXS is powered with four or five Mercury V-12 600 horsepower engines, producing up to 3,000 horsepower, with a top speed of approximately 60 mph, a fast cruise of 40 mph and a range of approximately 500 miles. The LX Series flyer, writing about the LXS specifically, is more conservative: five Mercury V-12 600s, a projected top speed in the upper 50s, the same 40 mph fast cruise, and approximately 450 miles.
Plan off the conservative pair. And note what the two documents agree on: engine count is an option on both boats, not a difference between them.
Every speed number attached to this boat is a builder projection, which makes the sea trial - with the engine count you actually intend to order - the place where the verifying happens.
You can still do arithmetic on Scout's own two numbers. Fifteen hundred usable gallons against approximately 450 miles is roughly a third of a mile per gallon as a planning figure, and range estimates normally hold a reserve back, so real economy should be a bit better.
Carbon into the stringers, the deck and the hardtop
Scout has built carbon-epoxy hulls at the top of its range for years. On the 670 the laminate goes further than the hull: carbon fiber and fiberglass infused stringers, an infused deck, and a carbon fiber epoxy infused hardtop frame support.
If your marina, your lift or your insurer needs a rigged weight or a draft, get the number in writing on the build sheet - Scout's flyer lists the draft at 37 inches and the model page at 41.
Three staterooms, and Scout publishes the headroom
This is where the 670 stops being a large center console and becomes something else. Three staterooms, two heads, and standing heights Scout actually puts in print: every standing area in the cabin is at least 6 feet 7 inches, and the upper interior atrium has 7 feet of headroom.
The master has a single queen berth on a powered hydraulic bed with storage underneath, a lighted hanging closet, and en-suite access to the day head and a separate shower. The aft VIP is a double berth behind a lockable door with its own standup area and en-suite access to a separate head and shower. The third cabin is an aft crew stateroom with twin berths and a lockable door. Every berth ships made up, and the lower cabin area is carpeted throughout.
The atrium is what you get instead of a flybridge
Take the upper station off a 67-foot boat and the question becomes what replaces it. On the LXS the answer is inside rather than above.
The galley is not below decks. It is on the main deck, in what Scout calls the upper interior atrium: a two-burner induction stovetop with an exhaust vent, a convection oven and microwave, two Jennair drawer refrigerators and a Jennair drawer freezer, and a 15-inch round hot and cold sink. Seating is a wraparound couch for five, with storage inside it and beneath it, around an electrically actuated high/low dining table that expands.
The detail that defines the room is the window. A 6-foot-8 aft window drops electrically, and the atrium and the cockpit become one space. Forward of it, behind a lockable glass door, is the lower salon: a 7-foot-2 couch over storage, a 32-inch smart TV, a Garmin 943 MFD with full vessel controls, and panoramic overhead glass with an electric shade. Between the two, the mid-deck breezeway carries a 6-foot-5 bar top with two Release Marine 360-degree swivel stools. Forward, the bow has a 50 square foot sun lounge pad on backrests that lie flat or raise up.
The hardtop above all of it stays clean, reached by a concealed ladder and a Lewmar hatch, with a sliding fiberglass sunroof and an electric shade garage on the option list. Scout's standard Garmin layout is a single starboard-side helm; a second pair of screens to port is an option rather than a second station.
Systems match the accommodation: a Kohler 24 kW diesel generator on a dedicated 184-gallon tank running two Dometic variable-speed chillers totalling 48,000 BTU, two powered 50-amp shore cords, separate AGM 12V and 24V banks, Zipwake trim tab control, and real teak decking through the cockpit and breezeway as standard.
It still fishes, it just does not lead with it
Standard fishing equipment on the Sport version is not token: two 60-gallon in-floor fish boxes, 30-gallon baitwells port and starboard with see-through windows and Hooker electric pumps, six flush-mount gunnel rod holders and nine at the transom.
What tells you which configuration you are standing on is the transom. The LXS ships with a versatile 20/60/20 transom: baitwells port and starboard around integrated centre couch seating with a storage box underneath. Scout's sportfish transom, 30/40/30 with large pressurised baitwells, a five-tube tuna tube system, full-width bolsters and walk-through gates, is an option here, and it is the transom Scout requires if you want a fighting chair.
Two hydraulic fold-down beach platform doors take the beam from 16 feet 2 inches to 19 feet 6 inches when they are open, with a dock access step built in and stowage for the boarding ladder.
Who this boat is for
The 670 LXS is for the owner who has outgrown a center console, does not want a sportfish, and wants the entertaining spaces at the front of the design rather than bolted on behind the fishing. Three staterooms, two heads with separate showers, a main-deck galley, air conditioning that runs all night off a generator already aboard, and a walkaround deck with beach platforms on both sides.
It is the wrong boat if the upper station is the point - that is the 670 LXF, same hull, same engine options - or if you need tested numbers before you commit - here the figures are projections, and the proving happens on your sea trial.
Everything else is settled at the order desk, and the first question on the sheet is the one Scout's website will not answer for you: upper station, or no upper station.
