Captain's Report

By Capt. Steve


Yes, you can have it all. And it’s all in one package with the Canyon 336.  This model has been around for quite some time, but Grady-White has recently upgraded the boat to include a boatload of features thanks to listening to the voice of the customer.  The result is a 336 that’s better than ever.   

Grady-White Canyon 336

 The Grady-White Canyon 336 is improved from stem to stern, keel to hardtop.   

The build quality is a lot of what separates a Grady-White from the competition. They all have the characteristic wide flared bow, ala Carolina flare, that conjures up images of the big game fishing boats. There’s a 50+ degree deadrise at the bow for excellent wave penetration. Her trademarked SeaV2® hull design varies that deadrise that reaches 30 – 35 degrees at midships and continues to flare until it reaches 20-degrees at the stern, providing her offshore handling characteristics.

All Grady-White boats have a hand-laid fiberglass hull with a fiberglass grid stringer system laid in and bonded to the hull. Foam is injected into all the void areas, making each Grady unsinkable.

So, What’s New?


One of the first things Grady-White focused on, in its list of improvements, was the console.  It’s much bigger now and therefore can accommodate new and larger electronics displays.  Our test boat had a pair of 17” (43.18 cm) screens, and if the Yamaha and VHF were to be relocated, the panel could easily accept three 12” (30.48 cm) units.  Because it’s a larger and higher panel, I’d like to see the addition of a step at the deck to elevate the operator.  I’m of average height at 5’8” (1.73 m) and I was occasionally losing sight of the horizon ahead.   


The T-Top has been given a re-design that now accommodates integration into the full wrap-around windshield, protecting the operator and observers without having to look through curved glass.  An electrically actuated opening vent is at the top, adding much appreciated ventilation to the helm area. But if that’s not enough, there’s also an option for air conditioning with vents aimed right at the helm seat area.   This will also require the 5kW generator upgrade.

An electronics box is located just above the helm and a zippered PFD storage is just behind.  In addition to the LED spreader lights, there are speakers, courtesy lights, grab rails integrated into the supports, and there is an option to add outriggers.  

The top was also redesigned to accommodate the optional SureShade® electrically retractable awning w/Sunbrella® canvas that extends well out to the aft section of the cockpit at the trailing edge.   The new arrangement makes the awning much less bulky, and now the mechanisms are well hidden and protected.  

The T-Top is fully featured and includes PFD storage.  Most important is how it integrates into the windshield.   

A SureShade® electrically retractable awning in now integrated and concealed into the top of the hardtop.  


By redesigning the console, Grady-White was able to pick up almost 2’ (.61 m) of headroom inside the cabin, bringing it to 6’2” (1.88 m).  The old electronics box used to drop down and impinge on the available space.  No more.  Now it’s more of a flush overhead.  The 7’4” (2.34 m) berth has also benefitted from a re-design so that it’s not only roomier, but a ratcheting cushion in the middle converts the berth into a sitting area.  Additionally, thanks to more space overhead, six vertical rod racks have been added to this lockable compartment. 

Inside the cabin, there’s a berth that now includes a flip seatback to convert to a sitting area.  Notice the rod that is in one of the 6 vertical rod holders.    

Hull Side Door

Previously an option, the inward opening side door is now standard.  The latching system is exceedingly easy to use, and the door swings on heavy duty hinges.  Because it opens inward and is low to the waterline, there is the added advantage of using it as a boarding location from a floating dock or a tender.  

The hull side dive door is now standard on the 336 and loaded with impressive features.

Yamaha Helm Master EX with Full Maneuverability

A big change is that the Canyon 336 now comes with a full upgraded control system thanks to the Yamaha Helm Master EX system.  It includes...

  • Digital Electric Steering – It begins with a new digital electric steering system. Now that this has gone digital, it was easy for Yamaha to add features like Joystick steering and an autopilot tied into the GPS so that the boat will automatically follow selected waypoints, and even several waypoints built into a route.    
  • Electronic Key System – The ignitions have new start/stops that are activated with a floating key fob.  If the key fob isn’t near the ignitions, the engines won’t start.  It can be overridden with a code, but for all intents and purposes, the fob needs to be near the helm.  
  • Full Maneuverability Package – This is an optional feature that Grady offers on the 336. The joystick provides the improved maneuverability at the dock, no surprise there.  However, additional features include Stay Point that will hold position and heading, Drift Point that holds the heading but not position,  and Fish Point that allows us to set the bow or the stern to hold position while the opposite is allowed to swing with the wind or tide.   

The joystick also has +/- buttons so we can adjust the thrust while maneuvering on the joystick.  This isn’t a remarkable feature as all joysticks have adjustable power, but what is remarkable is that others only have a hi/low setting.  This unit, however, allows adjustment through five individual power settings for extremely precise maneuverability.  

The Helm Master joystick has many new features, including three station keeping modes and five power adjustments
  • New Control Binnacle – The digital engine controls are upgraded to include the usual individual trim buttons.  But there’s also a new Cruise Assist feature.  On the left throttle (the primary with single lever control), there’s not only the trim button but also a +/- button that will adjust the speed in 50 RPM increments.  It has a full range of 450 RPM before the throttles need to be moved again and the cycle can start over.  So, while we can’t just keep hitting the + button from idle on up to full speed, we can dial in a more precise speed setting without gently tweaking the sticks. 

It gets better.  When trolling at idle speed, start dropping the speed down even further with the – button, and the system will actually start taking the engines in and out of gear… 90% in and 10% out, right on down to 10% in and 90% out for really slow troll speeds.  

Miscellaneous Improvements

Those are the major changes.  Some are much more subtle.  All the upholstery has improved stitching that’s not only more appealing, but stronger.  The sound system has been upgraded to a Fusion Apollo series with top of the line Signature Series speakers and a subwoofer to the port bulwarks.     

Now let’s go over the rest of the boat’s features, starting with the principle mission of the 336… fishing. 

The Fishing Features


The 28-sq.-ft. (2.60-sq.-m.) open cockpit is the business end of the fishing features.  Padded bolsters run all the way around the boat, and in the cockpit, they top out at 28” (71.12 cm).  Horizontal rod storage is in the bulwarks as is a convenient toe rail.  

There’s a 291-qt. (275.39 L) transom fishbox that can be upgraded with a digitally-controlled refrigerator/freezer option.  Alongside the transom door to the swim platform is a freshwater washdown, so cleaning rods is not an issue.  To the port bulwarks, there’s both a fresh and raw water washdown so we can get the whole boat cleaned in short order.  

Just ahead at the rigging station, there are two livewells (45-gallon (170.34 L) and 26-gallon (98.42 L)).  The smaller is optional and without that option chosen, it will be a standard 104-quart (98.4 L) cooler.  Between is a cutting board and a freshwater washdown, and all water gets channeled down the angled deck to the aft drains that lead overboard.  Tool holders are just above.  Below is storage that includes a set of four tackle sorters.  

The rigging station includes one, or two, livewells.  A freshwater washdown is between with a cutting board.  Below is storage.  

Rod storage is the least of the concerns on the 336.  There are six rod holders at the rigging station, four more across the trailing edge of the T-Top, 11 more in the caprails surrounding the boat and we could increase that by six if Grady would swap out the caprail-mounted beverage holders for combination rod/beverage holders.  

Speaking of the T-Top, it’s state of the art.  Aside from the plethora of LED spreader lights, there’s an option for adding the Taco outriggers.  

At the bow, there’s the ability to remove the cushions and insert a lowered table that will then create a full casting platform.  Under the V-seats, there are 204-qt (193.06 L) fishboxes that, along with all the livewells and aft fishbox, all drain overboard.  

The bow features seating that converts to a large casting platform.

The bow includes 204-qt (193.06 L) fishboxes under the side seats. 


Rod holders are everywhere on the 336, starting at the tackle station.  

The Family Features

Family features have to start with the patented fold-away transom bench seat.  Grady-White was smart to get a patent on this design.  It’s flat-out the easiest we’ve seen to deploy and stow.  At the entrance to the swim platform, there’s a freshwater shower with a hot/cold mixer to clean off after reboarding.  

The transom bench seat is easy to deploy and stow away.  

A transom gate leads to the swim platform and the four-step reboarding ladder.  A freshwater shower is right alongside. 

At the bow, the V-lounge seats have standard swing-away backrests that provide either additional comfort or more room for moving about.  Storage is underneath.  A table can be added to increase the functionality, and this can be lowered to form a sunpad with the addition of a filler cushion.  Receivers are built into the caprails to accommodate carbon fiber stanchions that will support a bow sunshade.  A double-wide seat is ahead of the console. 

Grady-White has made a comfortable and functional bow seating area.  Notice the high padded bulwarks.  

With the filler cushion in place, the sunpad measures 7’4” (2.23 m) across at the aft end, 5’ (1.52 m) at the forward end and 4’7” (1.40 m) fore and aft. 

A shade can be added to the bow for additional comfort.  Notice the swing-away seatback.  


We discussed the improved features of the cabin, such as the new berth layout and higher headroom, earlier in this report.  Further accommodations include a VacuFlush toilet plumbed to a 10-gallon (37.85 L) holding tank.  A sink with Corian counter is right alongside and the pullout sprayer allows for showering in this “wet-head” compartment.  This is plumbed to the boat’s 38-gallon (143.85 L) freshwater tank.  At the aft bulkhead, there’s an enclosed microwave.  If the 5kW generator option is chosen, there is also a water heater option available, and the air conditioning can be run offshore.  Otherwise, the AC is powered from the standard shore power.  

The head includes a VacuFlush toilet and a sink is right alongside.  Notice the flip-down teak rod holder that holds rods vertically.  It’s attached to a hinged panel allowing for electronics access behind the helm panel.  Above is a concealed microwave.  

The Operational Features


We’ve discussed the improvements to the helm console earlier in this report.  Now let’s discuss the remaining features.  

Starting at the top of the console, there’s a recessed, padded area for putting the quick drop items. Grady-White thoughtfully added channels to the sides to direct any water that may collect in this area out the sides and onto the deck.  Just below are two carbon fiber panels holding rocker switches with breakers right alongside each switch.  It’s also nice to see the important horn switch standing out in red.  All these switches are flanking a center, dash-mounted compass with heading displays at both the leading and trailing edge.  

Below the main 17” (43.18 cm) displays and to the left of the console is a cubby with a padded surface and connectivity.  An Apollo series Fusion stereo is below that.  The helm seats are three across, which allows Grady-White to incorporate a center-mounted helm station for better all-around visibility.  And it’s always nice having extra eyes watching out when underway.  All seats are well-padded and ventilated, slide fore and aft, and all include flip armrests and flip bolsters.  Below are two flip-down footrests in a 1/3-2/3 configuration.  The wider is because there’s a hatch behind that opens to reveal the vessel’s battery banks.  

The batteries are all easily accessible under the helm seats.  A larger flip-down footrest accommodates the hatch just behind.  

An optional bow thruster is controlled by a joystick to the left of the tilt wheel.  The stainless wheel also has rubber grips on the top and underside, and we always appreciate the addition of a steering knob.    

Inside the cabin, there’s an aft storage compartment that is designed to accommodate an optional SeaKeeper 3 gyro stabilizer.  Just above is the vessel’s main power panel.  Battery switches are at the port quarter of the cockpit.    

At the aft end of the cabin, there’s a storage space that can accommodate a SeaKeeper 3 gyro stabilizer.  Notice the vertical rod holders.  

At the bow, there are two 8” (20.32 cm) pull-up cleats and these are the first of six located throughout the boat.  These cleats flank a hatch that opens on a turn and lock latch to reveal a Lewmar windlass leading to a through-the-stem anchor roller.  Two control switches are just to the right.   

The windlass is under a hatch at the bow.  The hatch is finished on both sides and held open by a single gas strut.  

By lifting the aft bench seat out of its tracks, we gain access to a hatch that conceals the extended levers connected to the boat’s seacocks.  All are neatly labeled.  Battery switches are in a hatch right alongside.  

Test Numbers

The Grady-White Canyon 336 has a LOA of 33’6” (10.21 m), a beam of 11’7” (3.53 m) and a draft of 26” (66.04 cm).  With an empty weight of 10,165 lbs. (4611 kg), full fuel and full water and four people with gear onboard, we were heavily laden at an estimated test weight of 15,565 lbs. (7060 kg).

With a pair of 425-hp Yamaha XTO Offshore 4-Stroke engines turning 16 5/8 x 19 props and wound up to 6000 RPM, our speed topped out at 50.6 MPH.  Best cruise was measured at 3500 RPM and 25.1 MPH.  It was at that speed that the 23.8 GPH fuel burn translated into 1.1 MPG and a range of 343 miles, all while still holding back a 10-percent reserve of the boat’s 361-gallon (1366.5 L) total fuel capacity.  

Twin 425-hp Yamaha XTOs brought to a top speed of 50.6 MPH.  


As for her handling, she’s an exciting boat to drive.  Shove the throttles to the stops and she’ll come up on plane in an average 4.4 seconds, accelerate to 20 MPH in 6.5 seconds and blow past 30 in 11.4 seconds.

Once she’s up on plane, bring the outboard trim up to about the halfway mark on the scale to put her into her optimum running attitude.  There won’t be much change in her running angle, but the props will be more efficient.  

With the engines properly trimmed for running, there won’t be much change in the running attitude.

Turns are a non-event with an average 15-degree roll into the turn.  There is no chine walk or prop ventilation during the turns, but hard performance turns will have an effect of gripping the water, so a good hold on a grab rail is required.  Average turns eliminate this need.  

Any boat with Canyon in her name has to perform well offshore.  And it’s here where the 336 delivers the goods.  Her wide flared bow with its narrow entry delivers.  She’ll slice through the waves with the spray being thrown low and wide for a dry ride.  In a following sea, there’s no hint of stuffing the bow, thanks to the flare providing so much buoyancy.  In head seas, she shows no pounding or hull slap, and if she does catch air, she remains in a level attitude and produces a smooth reentry.  

If the Canyon 336 catches air, she has a smooth reentry and just continues on with no adverse effects.  

In a following sea, she throws water wide and low.  We were unable to get any spray on the windshield. 



The Canyon 336 is a boat that continues to impress, more so with these latest changes.  Grady-White has always been a company that listens to the customer, and these improvements are an example of exactly that.  She’s an excellent performer, and as an offshore fishing platform, she leaves nothing to be desired.
