Regulator 37 Fuel Capacity, Specs, Range and Price Guide

Regulator 37 fuel capacity and every tank on board

Regulator 37 fuel capacity is 507 gallons of gasoline as standard, according to Regulator Marine's official specifications. An optional 90-gallon auxiliary tank raises the total to 597 gallons. The boat also carries a separate 21-gallon diesel tank, which feeds the onboard diesel generator, so generator running time never eats into the fuel you need to get home.

Fresh water is 50 gallons, the hot water heater holds 6 gallons, and the head's holding tank is 13 gallons. Those numbers answer most of the questions buyers ask about the 37, because they define how far the boat can go and how long a crew can stay aboard.

• Gasoline, standard: 507 gallons
• Optional auxiliary gasoline tank: 90 gallons, 597 gallons total
• Diesel for the generator: 21 gallons
• Fresh water: 50 gallons, hot water heater 6 gallons
• Holding tank: 13 gallons

How far 507 gallons really goes

With triple Yamaha 425 XTOs, Sport Fishing measured 0.81 mpg at 37.3 mph and 4,000 rpm, the most efficient cruise. That works out to about 46 gallons per hour. Sport Fishing's later test with XTO 450s recorded 38 mph at 4,000 rpm and a maximum range of 370 miles with a 10 percent reserve.

Treat 10 percent as untouchable. That leaves about 456 usable gallons from the standard tank and roughly 537 with the optional tank. At 0.81 mpg the standard boat gives about 370 statute miles, and the auxiliary tank adds roughly 70 more. Boating took a more conservative view, calling the range about 300 miles, which better reflects real offshore days with rough water, trolling and a full crew.

For most owners 507 gallons is enough for canyon runs from the Mid-Atlantic or trips to the Bahamas from South Florida. The auxiliary tank makes sense if you regularly fish 100 or more miles out or want to cross without refueling.

Lou Codega's 24-degree hull, with no steps required

Regulator has used Lou Codega designed hulls for decades, and the 37 follows the formula: a non-stepped deep-V with 24 degrees of transom deadrise, solid fiberglass bottom and a bonded grid stringer system. At 12 feet 7 inches the beam is generous for the length, and the 37 weighs 19,300 lb with engines, much heavier than many rivals.

That weight and deadrise produce the ride Regulator is known for. Boating described it as an easy, dry ride, and the hull feels planted in a head sea. Without steps, the 37 is predictable at all speeds and does not demand a skilled driver, which suits family owners. The trade-off is efficiency; stepped hulls of similar size can run faster on the same power.

Triple Yamaha XTO power, 425 to 450

The 37 launched with triple Yamaha 425 XTO Offshore V8s and now comes with triple XTO 450s, rated for a maximum of 1,350 hp. Sport Fishing recorded 60.2 mph at 6,000 rpm with the 425s and acceleration to 20 mph in 5.6 seconds. Boating recorded 56.3 mph at 6,000 rpm with the same engines, a difference that reflects load and conditions.

Helm Master EX joystick control and autopilot are standard on many boats, and Sport Fishing called the joystick among the most responsive in the industry. Regulator's MyHelm digital system ties the helm together with a touchscreen and wireless key fob. The 37's draft is 34 inches with engines up and 46 inches with engines down.

Fish boxes, livewells and the triple-helm deck

The fishing layout is generous. Forward, a center fish box or dry storage holds 420 quarts, two forward seat fish boxes hold 154 quarts each, and a settee cooler holds 227 quarts. Aft, two 311-quart insulated, macerated in-deck fish boxes, a 322-quart transom fish box and two 33-gallon transom livewells cover the needs of most offshore trips.

Six rocket launchers, rod holders, a windlass with a freshwater anchor wash and an optional tower complete the package. The triple helm seats sit on a module with tackle storage and a slide-out grill, a detail that shows how Regulator balances fishing with family use.

The cabin, head and the 13-gallon holding tank

Below the console, the 37 has a proper cabin that sleeps two on a V-berth, with a galley module carrying a refrigerator, microwave and sink, plus air conditioning and a skylight for natural light. The enclosed standup head includes an electric toilet, a sink with hot water, a shower and a towel rack. Boating measured 6 feet 11 inches of headroom, a figure that surprises people who have only been inside smaller center console cabins.

The 13-gallon holding tank is the number that matters for anyone planning several nights aboard. It is fine for day trips and a weekend with two people, but a family of four on a three day Bahamas run will be looking for a pump-out by day two. The same logic applies to the 50 gallons of fresh water once the shower is in regular use. Plan stops accordingly, or treat the cabin as a comfort station rather than a liveaboard space.

For daytime use the cabin is a genuine asset. It gives children somewhere cool to nap, keeps phones and dry clothes out of the spray, and makes the 37 a viable boat for owners whose partners would never consider a pure tournament console.

Generator diesel, gyro and pump room

The 21-gallon diesel tank exists for one reason: the diesel generator that runs the cabin air conditioning and galley. Keeping the generator on its own diesel supply means you can run it all afternoon at the sandbar or overnight at anchor without touching the gasoline you need to get home, and diesel generators are generally quieter and more fuel efficient than gasoline units in this size.

Regulator groups the systems in an illuminated pump room under the deck, with access designed for routine service rather than contortion. The optional Seakeeper 5 gyro lives there too. Watertight bulkheads add a margin of safety that Boating singled out in its test, and the MyHelm digital system lets owners monitor and switch circuits from the helm or a key fob.

On a used boat, ask for the generator's hour meter and service log, confirm the gyro has had its scheduled bearing service, and run the air conditioning for at least half an hour during the survey. These are the most expensive items to fix after the engines.

Edenton build quality and Regulator's offshore reputation

Joan and Owen Maxwell founded Regulator in 1988, starting in an abandoned grocery store in Edenton, North Carolina, and the company still builds there in a modern plant just down the road. The first Regulator 26, launched around 1990, was named the best up-and-coming center console by Sport Fishing, and Lou Codega hulls have been central to the brand's identity ever since.

Regulator's reputation was built off the Outer Banks, where inlets are rough and offshore runs to the Gulf Stream are long. That heritage shows in the 37's weight, deadrise and heavy hardware. The boats are a common sight in Mid-Atlantic and Carolina billfish tournaments and in Northeast canyon fleets, though the 37 itself is more of a do-everything family offshore boat than an all-out tournament machine.

Resale reflects the brand's standing. Regulators tend to hold value better than most production center consoles, partly because the owner base is loyal and partly because the hulls age well.

Price, running costs and used values

New Regulator 37 prices start around $1 million and approach $1.2 million with the tower, gyro, auxiliary tank and upgraded electronics. That is a big step from the $749,995 Sport Fishing quoted in 2021 and the $829,780 Boating listed in 2022, reflecting both inflation and the move to XTO 450s.

Used boats from 2021 onward generally list from about $640,000 to $1 million. Gyro-equipped boats, those with the 90-gallon auxiliary tank and boats with low-hour engines command a premium. Expect XTO outboard service to run several thousand dollars per engine per year, and add insurance, storage and systems maintenance for a total of roughly $42,000 to $85,000 a year before fuel and depreciation.

Fuel itself is substantial. At about 46 gallons per hour at cruise, a 150 mile offshore day burns close to 185 gallons, roughly $900 at $5 a gallon.
