Captain's Report

Formula 310 Bowrider

With multiple color options the boring white on white is a thing of the past. The optional tower really adds to her utility without harming her striking good looks.

Mission Statement

The mission of the 310 Bowrider couldn’t be more clear. She’s the second largest bowrider by Formula offered and will satiate the desires of those that have no intention of spending the night onboard, but do plan on spending the days on the water with a boatload of friends. She has the amenities, space and good looks to impress virtually all comers.


By having forward-facing seating for 8 adults, underway they can all enjoy the thrill of boating at high speed and see where they are going in comfort. When cruising more slowly, or when at rest, she can easily seat 14 people in comfort -- as many as most pontoon boats. With her wet bar and options of a refrigerator and grill she can also become a venue for daytime picnics and evening BBQs.


She is also watersports capable and able to get on plane relatively fast to pull skiers. Her 10,792 lbs. (4,895 kg) as tested will help create wake that wakeboarders will enjoy. She is about as big as is relatively easy to handle for these kind of activities.

Razzle-Dazzle 'em.

Her final -- and usually unmentioned – mission, as alluded to above, is the "wow 'em" with her sheer beauty, grace and eye-dazzling finish.

Formula 310 Bowrider

With twin 320-hp engines our test boat was able to break the 50 knot barrier with three people aboard. Just imagine how fast she would go powered by twin 430-hp engines.

Distinguishing Features

Strong Warranty.

Formula stands behind its products with a 10-year structural warranty and a 5-year transferable "Formula Guard" protection plan. This plan includes engine and outdrives for five years.

Choice of Graphics.

Most builders have a “one-and-done” policy regarding graphic choices. Not so with Formula. There are three different choices so that the 310 Bowrider can be dialed in to the specific look that owners are striving for.

• Certainly far more durable than the decal counterparts.

DuPont ChromaPremier Paint.

Formula uses this high-quality paint that has a bright luster, then covers it with clear coat for durability and longevity of high gloss. (See below).

Polished to Perfection.

Formula’s are always easy to spot among the throng of boats. They’re the ones that look far and away better than the rest. On our tour of the Decatur, Indiana plant, we paused at the end of the line to watch a boat being finished out. No less than four workers were at the hull with orbital buffers bringing out the perfect shine. When one of them stepped back to admire her work, we joined in and looked at the mirror-like shine. We saw no flaws or imperfections in the reflection.

The video on Formula's "polish-to-perfection" construction method…

Excellent Tooling.

Formula knows that much of its premium reputation is because of the exceptional cosmetic nature of its hulls. Look at any Formula hull at a boat show and notice the play of light across the surface. Their hulls do not reflect light in waves much less as a washboard. The reason is because the plugs were board sanded for hundreds of hours. Then the molds have been maintained and polished to maintain the fairness of the plugs.

Formula 310 Bowrider

Naturally we’d like to see this engine hatch open a bit wider but it still leaves access for the daily checks. For more involved maintenance, the electric ram can be disconnected allowing the hatch to be opened fully.

Major Features

Single Level Deck.

The deck maintains a single level from the cockpit to the bow, no steps, and this keeps everyone on the same conversational level as well as making transitions back and forth much easier.

Concealed Fiberglass Anchor Locker.

This creates a cleaner, and more uncluttered bow.

Eight Formula Cast Cleats.

The cleats have the Formula logo cast into them.

Air Horn.

We would have expected a basic electric horn on a bowrider, but an air horn is a step above.

Bennett Trim Tabs.

Formula has chosen to stick with the tried-and-proven hydraulic trim tabs and has not gone with the newer, less expensive electric ones. These are standard and include LED indicators to the sides.

Polished Stainless Steel Engine Vents.

Where we often see chromed plastic vents that peel over time, these vents not only look good, they’re durable.

Extended Integrated Swim Platform.

This optional platform not only adds to the usable space to enjoy the platform, but keeps the sharp edges of the outdrive well clear of any swimmers boarding from the concealed ladder. It has been expertly designed and engineered to fit seamlessly with the stern. We recommend it for any owner planning on swimming from the stern or being engaged in towing sports.

Choice of Helm Panel Materials.

Choose between a silver burl or a wood and brushed metallic finish. The steering wheel hub matches the panel choice.

Garmin GPS.

The panel comes standard with a Garmin 536 GPS with color chartplotter, along with a digital depth sounder.

All-Weather Cockpit Seating.

Wet seat cushions are not much fun. But that will not be going on in a Formula boat because its cushions are made with DriFast foam that allows water to flow right through to drain holes underneath. This foam does not hold water. And they are made to withstand the elements.

Molded Wet Bar.

It includes an integrated sink, Corian counters, a 24-quart (27.7 L) igloo cooler, trash container and safety rail.

Doublewide Helm and Companion Seats.

At the helm we can have a second set of eyes looking ahead, the companion seats face the helm and there’s integrated dive tank storage underneath.

Modular Bow Seating.

Converts easily to a sun pad with dedicated storage for the filler cushion under the starboard seats.

Standard Head.

Formula provides a standard VacuFlush head with 36-gallon (136 L) holding tank and dockside pumpout.

Bow and Cockpit Covers.

Very surprising to see this as a standard feature but Formula apparently doesn’t want to run the risk of a short-sighted owner failing to cover this premium boat. These aren’t giveaways either… they’re color matched, and made from non-fading Sunbrella acrylic fabric with SeaMark and vinyl undercoating.

Automatic Discharge Engine Room Fire Extinguisher.

Another item typically seen as an option but one we’d never want to be without. There is also a standard fume alarm in the engine room. Formula also includes a separate extinguisher mounted in the cockpit.

Formula 310 Bowrider

The engine installation is roomy enough and the compartment itself is clean and orderly.


The Formula 310 Bowrider has a LOA of 31’ (9.45 m), a beam of 9’6” (2.90 m), and a draft of 37” (.94 cm). With an empty weight of 9,875 lbs. (4,479 kg), 40% fuel and three people onboard, we had an estimated test weight of 10,792 lbs. (4,895 kg).

WOT Speed.

With a pair of 320-hp MerCruiser 377 MAG engines turning BIII outdrives with 26 pitch props, we reached a top speed of 51.8 mph at 5000 rpm. At that speed we were burning a combined 51.4 gph giving us a range of 118 miles.

Best cruise

came in at 3500 rpm and 34.1 mph. That speed reduced the fuel burn to 20.4 gph producing a range of 196 miles and an endurance of 5 hours 42 minutes while still holding back a 10% reserve.

We reached planing speed

in 4 seconds flat. Accelerated through 20 mph in 6.2 seconds, 30 in 9.1 seconds, 40 in 13.2 seconds, and eased past 50 mph in 20.5 seconds.

Formula 310 Bowrider

The helm seat is a doublewide version with individual flip-up bolsters.


This is a great boat to drive. She has a solid feel of a heavier boat and her 5-degree bow high cruise attitude feels as if it’s on a more level plane. The bow comes up only 10-degrees upon acceleration producing no loss of visibility to the horizon. With 2 ½ turns from lock to lock on the wheel she responds smartly to helm inputs and she slices cleanly through the wakes of passing boats rather than launching over them. Spray is kept low for a dry ride in addition to being a comfortable ride.


Formula went with an attractive and functional helm that includes a Garmin 547 GPS as standard. Two choices of Raymarine units are available, the e7D ($2,170) or the e97 multifunction display ($5,250). There is full instrumentation in the panel, even with the addition of either the Mercury VesselView or the Volvo Penta EVC display, depending on which choice powers the boat of course.

Formula 310 Bowrider

A chartplotter, digital depth sounder and aircraft-style compass come standard.

Formula 310 Bowrider

To the starboard side are Mercury’s DTS control system, Bennett trim tabs with LED indicators and the Axius Joystick just ahead. Note the color of the gel coat on the helm console blends with the upholstery colors and the hull sides.

To the starboard side, our test boat was controlled with Mercury’s DTS control system, which offered a host of optional features such as engine sync, single lever operations and dock mode for lower power settings. We were also equipped with the Axius Sterndrive Joystick System, which gave us flawless operations around the dock with near surgical precision.


Formula 310 Bowrider

Formula’s 310 Bowrider offers plenty of room to move about, even with all the seats occupied.

The big news with this 310 Bowrider is the newly styled interior, and it’s based largely on customer feedback. By designing “alcoves” into the seatbacks, Formula is able to add ancillary items such as drink holders and grab handles without impeding on the available space of the seat itself. Multiple shades of earth tones keeps glare knocked down, and different densities of foam used in the construction add comfort where it’s needed most.

Formula 310 Bowrider

The U-shaped seating wraps around a base for the standard cockpit table.

Formula 310 Bowrider

The seats have been redesigned with alcoves under the seatbacks that allow Formula to include items such as drink holders and grab handles without impeding on the amount of available seating.

We still have the usual accommodations for storage underneath the seats, and all the cushions are attached to double hinges that allow the “hatch” to remain open without having to hold onto it. This allows both hands to be free to work the compartment.

Formula 310 Bowrider

Shade is provided by this optional stainless arch ($9,560). A white fiberglass arch is available ($7,395) as well as a hardtop option ($12,145).

Drinks Anyone?

To the port side is a wet bar with a Corian countertop that is available in a choice of three colors, Lava Rock, Sonora and Tumbleweed, with no upcharge. There’s adequate counter space for food prep, and underneath we have a trash receptacle and a sink.

Wet Bar Options.

There’s storage to the left, and this compartment also includes the house battery switches, while to the right is a pullout cooler. This cooler can be swapped out for a cockpit refrigerator with a stainless front ($2,025). With that option, we’d like to see the white acrylic door removed for better access. If a grill option is chosen ($1,360), then it mounts to a side-mount pedestal at the transom rather than into the wet bar.
We like this concept as it frees up space by the wet bar and takes advantage of unused space on the swim platform.

Formula 310 Bowrider

The wet bar has Corian counters with a sink and trash receptacle underneath. The hatch to the sink is held with a gas strut.

Observer's Seat

Just ahead of the wet bar is a double wide observer’s seat that can be used while facing forward and watching the road ahead, facing aft and watching the wake shining in the distance, or spotting a performer at the end of a tow rope. Otherwise guests sitting here can face the captain and enjoying the scintillating conversation that they always offer.

Formula 310 Bowrider

An observer’s seat to port has versatile seating options and storage underneath.

Head Room

Just ahead of the observer's seat is a head compartment. It comes standard with a VacuFlush toilet, 36-gallon (136 L) holding tank and dockside pump-out. The level of class continues here as well where we have Corian counters, a stainless sink, opening portlight for ventilation and a high-gloss laminate cabinet.

Formula 310 Bowrider

The head is in the port side compartment. It has sitting head room for even the tallest guest.

Formula 310 Bowrider

Inside there’s a standard VacuFlush toilet, Corian counter, stainless sink, and an opening portlight for ventilation. Interestingly, there’s a slide down window leading to the bow walkthrough as well.

Bow Seating

Forward, the bow is roomy enough to allow seating while facing each other and not worrying about knees knocking together. Used in the usual lounge style, there’s more than enough room to stretch out one's legs even for those who are 6'6" (1.98 m). Flip down armrests are provided, and this is a much more preferred method to flip-UP armrests that require releasing a latch to return to the stowed position.

Formula 310 Bowrider

At the walkthrough to the bow, there’s a slide-down window to the head. This is an unusual feature and a desirable one as well to keep the compartment from getting stuffy.

Formula 310 Bowrider

To the opposite side, two doors lead to the storage inside the helm console. The forward door also doubles as an air dam to keep the breeze knocked down on those chilly mornings.

Another neat feature is the ability to remove the center cushions from both sides. This creates two seats where guests can have their feet planted on the deck, much like a regular chair. The forward seat still accommodates the feet, much like an ottoman. And the seats can even be used in the same manner while facing aft. Again, the usual accommodations for storage are underneath.

Formula 310 BowriderFormula 310 BowriderFormula 310 Bowrider

Some of the many seating configurations that the bow seating offers can be seen here. All are quite comfortable and allow for plenty of room for others to join in on the conversation.

Formula 310 Bowrider

The possibilities with this bow seem numerous. For example, with the two filler cushions out why not put in a table where five could sit and have cocktails -- or even six with a jump seat?

Anchor Locker

Fully forward, Formula went with a concealed anchor locker. Our test boat was equipped with an electric windlass ($5,305) with 75’ (22.9 m) of all-chain rode and a stainless steel polished anchor. (Something that one really must have on a boat of this caliber.) A chain counter is at the helm.
We most appreciated that the hatch utilizes a lift-and-lock type of latch instead of the turn-and-lock type that always gets turned in the wrong direction and we only notice it when we start to accelerate and the hatch starts bouncing open. (Why manufacturers choose to use these is beyond us -- but thankfully Formula doesn’t!)

Formula 310 Bowrider

The windlass is optional, and considering the amount of time we spend at anchor while entertaining we wouldn’t want to be without it, especially on such a classy boat.

Swim Platform and Lounge

The swim platform is roomy, but our test boat was fitted with an optional extended platform ($6,810) that really added to the functionality. Both were fitted with the optional teak grained vinyl decking ($5,520). A stainless rail surrounds the platform and created a convenient handhold for those in the water. It also serves to absorb the hit into the dock should an errant captain be at the helm. Two drink holders are also accessible from the water.

Formula 310 Bowrider

With the standard and optional extended platform, there’s more than enough room to enjoy time spent at anchor while some of the guests are in the water. Note the location of the stern cleats -- when crossed they will not rub against the fiberglass bulwark that we see happen on some designs.

The aft facing rumble seat

has storage underneath and we always look to this for storing the wet towels and bathing suits as its position right over the engine provides a natural drying space. The seats also fold flat to form a sun pad.

Formula 310 BowriderFormula 310 Bowrider

The aft facing seat easily converts to a sun pad. We count 6 ss cup holders in this picture -- there are 17 in total on the boat.

Pricing and Notable Options

The Formula 310 Bowrider has a base price of $240,480, including the twin 320-hp MerCruiser 377 MAGs. We can drop down to 300-hp or bounce up to 430-hp engines but this seems to be a nice match for this boat in terms of speed and power.

Our test boat was equipped with

some options worth considering, including the Axius Joystick Operating System and Mercury VesselView display ($23,280). These engines were also equipped with the SeaCore saltwater protection system ($6,555). We strongly recommend this option if operating in saltwater. The electric windlass with chain and anchor is a helpful touch as we ALWAYS anchor out when enjoying our boats ($5,305). While the 310 comes with a color chartplotter, our test boat was equipped with an upgrade to the Raymarine e7D ($2,170).
Other options to consider are the stainless steel sport top ($12,145), the extended sport swim platform ($6,810) and the teak vinyl decking ($5,520). These options brought the “as tested” price of our 310 Bowrider to $306,650 MSRP.

Formula 310 Bowrider

Captain Steve examines the chemical bond between the re-molded, foam-filled stringer and the hull in a Formula FASTech boat under construction. The 310 Bowrider also has its stringers chemically bonded to the hull the same way.

Formula Construction

Frankly, we don't hear about many hull failures these days, but the few we do learn about usually involve someone beating the living heck out of boat going at high speed through square waves offshore. It's almost as if they are trying to tear the boat apart. Happily it doesn't happen often.

Born to Raise Hell.

Nevertheless, one of Formula's strong advantages -- and one of the reasons its boats cost what they do -- is that its hulls are built to take punishment. Because the builder came from an offshore racing heritage -- and is the ONLY major sportboat builder today which can say that -- it is well-acquainted with what can happen when a boat is abused, and it also knows how to keep its vessels together under the most challenging conditions. Failures under extreme conditions usually happen in one of the following areas--
1) Part of the hull delaminates
2) The hull-deck joint cracks
3) Interior bulkheads and cabinetry come adrift
4) Engines leave their mounts

Formula Building Techniques--

Formula 310 Bowrider

Captain Steve steps on a bulkhead that is "floating" above the hull by a slight gape that can't be seen because it is glassed over. Hat sections, stringers and angular boxes all add stiffness and rigidity to the hull.


Hull Construction:

Resin-encapsulated, suspended cross-framed stringer and bulkheads are securely bonded to bowrider hulls with biaxial laminates for optimal force distribution. Additional structural reinforcement – custom fiberglass shapes are used in the hull bottom and along gunwales.
See the video of Formula's hull construction…

Hull-to-Deck Joint.

Formula uses a chemical Plexus methacrylate chemical bond plus stainless steel bolts through stainless steel backing plates to join its hull and decks. Methacrylate adhesives provide a unique balance of high tensile, shear and peel strengths with the maximum resistance to shock, stress and impact across a wide temperature range. It is able to combine the properties of strength and elongation (flexibility) into a single high performance system, which gives excellent fatigue and impact resistance. As an adhesive, it is far stronger than fiberglass and resin.
Plexus is ISO 9001 certified and has been tested and certified by the world's most respected marine agencies, including Lloyd's of London, Det Norsk Veritas, Icelandic, and the American Bureau of Shipping.

Formula 310 Bowrider

Angled brackets connect cabinetry to bulkheads to keep them in place while pounding at speed through lumpy seas.


Bulkheads and Cabinetry Installation.

Formula's CAD/CAM routers cut wood parts to precise dimensions to fit perfectly. Then durable metal angle brackets are bolted into place to insure integrity. Bulkheads are glassed to the hull with a space in between to avoid contact. Drawers are premium quality and are dovetailed for added strength.
See the video on Formula's cabinetry making…

Engine Mounts.

All Formula engines mounts are thru-bolted using heavy-duty cast aluminum mounts and backing plates. This is far superior to lag screwing directly to stringers as in most other boat builders do in this class.


For the select few that can afford to be in this club, the Formula 310 Bowrider is a rewarding place to be. Formula doesn’t build boats that anyone would consider "cost-efficient", but that makes them even more special. Some consumers demand an exquisite product, and when it comes to boats, Formula delivers them.
