Choosing a marine chartplotter mount system means matching the mount to your boat, display, and preferred screen position—not just choosing a bracket that fits. I rank the Bzcovac adjustable-height mount first for its tall, highly adjustable layout, while the RAM Mounts D-size system is my pick for large displays where vibration control matters. For smaller consoles and lighter electronics, the RAM C-size short-arm mount offers a lower-profile alternative.

The main tradeoff is between height and positioning freedom and a more compact, direct installation. Tall risers can help lift a screen into view but take up more space and need a sturdy flat mounting surface. Ball-and-socket mounts keep the display closer to the console, though device compatibility depends on the ball size and mounting pattern. I compare all five options on those practical differences, plus marine-suited materials and installation demands.

More Details on Our Top Picks
Bzcovac Marine Electronics Mount with Adjustable Height and Swivel
I rank the Bzcovac first because it combines a useful height range with several independent adjustment points. Its 18–24-inch telescoping riser can lift a chartplotter above nearby controls, while the 350-degree monitor-plate swivel, 180-degree base swivel, and 180-degree riser tilt give the helm more positioning options than a short ball mount. That range is most valuable when the display must be visible from different standing or seated positions.
Compared with the similar-height 18–24-inch aluminum mount, Bzcovac lists more explicit articulation and a pre-drilled plate intended for several major brands. It also specifies anodized aluminum and stainless steel hardware, a sensible pairing for freshwater or saltwater use. The tradeoff is size: a tall riser occupies more visual and physical space than either RAM system, and the flat-surface base needs a suitable console location. The plate may not match every device, so I would verify hole spacing before installation.
Pros:- 18–24-inch height adjustment helps raise a screen above console obstructions.
- Separate plate, base, and riser adjustments provide broad screen positioning.
- Anodized aluminum and stainless hardware are specified for marine environments.
- Pre-drilled plate is described as compatible with several major electronics brands.
Cons:- Tall profile and base need considerable flat mounting space.
- The plate may not fit every chartplotter mounting pattern.
- Installation is limited to flat-surface mounting.
Best for: Boat owners who need to raise a chartplotter and adjust its position from multiple helm viewpoints.
Not ideal for: Owners of small consoles, anyone needing a clamp or rail mount, or buyers whose device does not match the pre-drilled plate.
- Material:Anodized aluminum with stainless steel hardware
- Height adjustment:18–24 inches
- Monitor plate swivel:350 degrees
- Base swivel:180 degrees
- Riser tilt:180 degrees
- Mounting type:Flat-surface mount
- Compatible devices:Fish finders, chartplotters, sonar and multifunction displays
- Weight:5 pounds
Our verdict“I recommend Bzcovac for buyers who need a raised, widely adjustable display and have room for a tall flat-mounted system.”
RAM Mounts Heavy-Duty Fish Finder Mount with D-Size 2.25-Inch Ball
RAM’s D-size system is my choice when a large compatible display needs a sturdy, adjustable mount without the height of a riser. At 8.125 inches overall, it sits much lower than Bzcovac or the other 18–24-inch option. Its D-size, 2.25-inch ball-and-socket joint lets the user adjust the screen angle, and the product description says the system helps isolate shock and vibration. That makes it a different proposition from the tall mounts, which prioritize screen elevation and reach.
The powder-coated marine-grade aluminum construction suits a marine installation, and the listed compatibility includes select Garmin, Lowrance, Humminbird, and Raymarine units. This is not a universal fit simply because those brands are named: the device must work with the mount’s pattern and D-size setup. Compared with the smaller RAM C-size model, the D-size mount is intended for larger electronics but is heavier and takes more room. It also requires drilling into a flat surface, so it is a poor match for renters, removable installations, or consoles without a suitable mounting area.
Pros:- D-size 2.25-inch ball provides adjustable positioning for compatible displays.
- Product description says the joint helps isolate shock and vibration.
- Powder-coated marine-grade aluminum is suited to marine conditions.
- Listed compatibility covers select devices from several major brands.
Cons:- Drill-down installation requires a suitable flat surface.
- D-size components and mounting patterns limit device fit.
- Shorter height does not lift the display above console clutter like a riser mount.
Best for: Owners of larger compatible displays who want a lower-profile ball-and-socket mount and value stated vibration isolation.
Not ideal for: Buyers seeking a tall riser, a no-drill installation, or a mount for a device outside the D-size system’s supported pattern.
- Model:RAM-D-111U-C
- Mounting type:Drill-down
- Ball size:D-size, 2.25 inches
- Overall height:8.125 inches
- Material:Marine-grade aluminum and high-strength composite
- Finish:Powder-coated
- Weight:3.7 pounds
- Warranty:Lifetime
Our verdict“I would choose this RAM system over a tall riser for a large, compatible display that needs a stout, lower-mounted ball joint.”
WINDFRD Aluminum Swing Arm Fish Finder Mount for 5–12 Inch Screens
WINDFRD takes a middle path between fixed-height risers and the shorter RAM ball mounts. Its six-inch swing arm has two pivot points with 360-degree rotation, giving the operator room to bring a display closer or change its direction without raising it 18 inches above the console. The stated screen range is 5–12 inches, and the mount is described for chartplotters, fish finders, marine GPS units, and other electronics.
Its powder-coated marine-grade aluminum and 316 stainless-steel hardware are specified for salty conditions. The listed 110-pound static capacity sounds substantial, but I would focus on the 22-pound dynamic capacity when judging a moving arm on a boat, particularly where vibration and leverage affect the load. Compared with Bzcovac, WINDFRD is shorter and offers a swing-arm layout rather than a telescoping riser; compared with RAM C-size, it provides two pivot points and a stated broader screen range. It still needs a flat surface, and the device plate and actual operating load deserve a fit check.
Pros:- Two 360-degree pivot points allow the display to swing and turn.
- 316 stainless hardware and powder-coated marine-grade aluminum are specified.
- Designed for stated screen sizes from 5 to 12 inches.
- Supplied fasteners include multiple screw and lock-nut sets.
Cons:- Requires drilling into a flat mounting surface.
- Dynamic capacity is 22 pounds, well below its static capacity figure.
- A six-inch arm may not provide enough reach for distant or elevated viewing.
Best for: Helms needing a short swing arm with two pivot points for a compatible 5–12-inch display.
Not ideal for: Buyers who need a tall raised screen, a rail or clamp mount, or whose moving electronics load exceeds the stated dynamic capacity.
- Material:Powder-coated marine-grade aluminum
- Hardware:316 marine-grade stainless steel
- Compatible screen size:5–12 inches
- Arm length:6 inches
- Rotation:360 degrees at two pivot points
- Static capacity:110 pounds
- Dynamic capacity:22 pounds
- Weight:2.3 pounds
Our verdict“I favor WINDFRD when a short, movable arm is more useful than a tall riser, provided the display and moving load fit its limits.”
RAM Mounts Fish Finder and Chartplotter Mount with Short Arm, C Size Ball
The RAM C-size short-arm system is the most compact choice in this group. Its 5.225-inch overall height and 1.5-inch ball suit installations where a chartplotter should sit close to the console rather than on a tall post. The 6.25 × 2-inch plate gives the buyer a defined mounting footprint, while the ball-and-socket joint allows angle adjustment after installation. At 1.1 pounds, it is also much lighter than the D-size RAM mount.
This compactness comes with a tighter fit requirement. The listing names select Garmin ECHOMAP Plus, GPSMAP, and Striker Plus models, Lowrance HDS Carbon and HDS LIVE 7, and compatible Humminbird and Raymarine units; it does not promise that every model from those brands will fit. Compared with the D-size RAM option, this mount is smaller and intended for compatible lighter setups, not the same large-display role. Compared with WINDFRD, it lacks a six-inch swing arm and two 360-degree pivots. Its drill-down installation also means the console must accept permanent holes.
Pros:- Compact 5.225-inch height keeps the display close to the console.
- C-size 1.5-inch ball allows adjustable screen angle.
- Powder-coated marine-grade aluminum construction.
- Lifetime manufacturer warranty is listed.
Cons:- Device and plate compatibility is limited to supported patterns.
- Drilling is required for flat-surface installation.
- Short height and arm do not offer the reach of the tall or swing-arm options.
Best for: Owners of listed or pattern-compatible electronics who want a light, low-profile ball mount on a flat console.
Not ideal for: Buyers who need a tall screen, a swing arm, a large D-size ball system, or a no-drill mounting option.
- Model:RAM-111U-B
- Mounting type:Drill-down
- Ball size:C-size, 1.5 inches
- Plate dimensions:6.25 × 2 inches
- Overall height:5.225 inches
- Material:Marine-grade aluminum
- Weight:1.1 pounds
- Warranty:Lifetime manufacturer warranty
Our verdict“I recommend this RAM mount for a compatible chartplotter when a compact, low-mounted position matters more than reach or broad device fit.”
18-24 Inch Adjustable Aluminum Fish Finder & Chartplotter Mount
This adjustable aluminum mount belongs in the same tall-riser category as Bzcovac, with an 18–24-inch height range and 180-degree tilt plus 350-degree swivel. Those adjustments help place a chartplotter where it can be seen without forcing the buyer into a short, console-hugging ball mount. Its rectangular plate has 16 mounting holes, which may help accommodate different installation patterns, though the listing does not provide a detailed device-by-device fit chart.
Compared with Bzcovac, the advertised movement and height are similar, but Bzcovac gives more specific details about its swiveling base, riser tilt, pre-drilled plate, materials, and compatible brands. That makes Bzcovac the easier choice when those specifics match the boat and display. This model’s anodized aluminum construction and multiple plate holes are useful, but a tall mount can overwhelm a small helm and requires drilling. The limited specification detail also means I would confirm the exact plate dimensions and hardware before committing to a particular chartplotter.
Pros:- 18–24-inch height range lifts a screen above the console.
- 350-degree swivel and 180-degree tilt allow screen angle adjustment.
- Anodized aluminum is specified as corrosion resistant.
- Rectangular plate has 16 mounting holes.
Cons:- Tall profile may be bulky on small boats.
- Drilling is required for installation.
- Device compatibility and mounting dimensions are not detailed as fully as Bzcovac’s.
Best for: Buyers who want an 18–24-inch adjustable riser and find its 16-hole plate suitable for their device and console.
Not ideal for: Small-boat owners short on console space or buyers who want the more fully specified mounting details offered by Bzcovac.
- Height adjustment:18–24 inches
- Material:Anodized aluminum
- Rotation:350-degree swivel and 180-degree tilt
- Mounting holes:16 on a rectangular plate
- Compatibility:Garmin, Humminbird, Lowrance, and more
- Mounting type:Flat-surface installation
Our verdict“I would choose this as a tall-riser alternative only after confirming its plate and installation details against the chartplotter and console.”
How We Picked
I ranked these systems by how well they solve the specific job of placing and holding a marine chartplotter. My first priority was adjustment that serves a clear purpose: lifting a display above console clutter, angling it toward the helm, or moving it aside. I then compared mounting styles, overall height, stated compatibility, materials, and the kind of installation each product calls for.
I gave the highest rank to a mount that balances useful range of movement with broad stated device compatibility. That puts Bzcovac first: it combines an 18–24-inch riser with a swiveling plate and base, although its footprint and flat-surface requirement make it unsuitable for every helm. RAM’s D-size mount ranks next for buyers who want a shorter ball-and-socket system for larger compatible electronics. WINDFRD follows as a flexible swing-arm option, with its 22-pound dynamic rating more relevant to moving or vibration-prone setups than its 110-pound static figure.
The two remaining mounts address different scales. The RAM C-size mount is a compact choice for its compatible devices, while the second tall adjustable system offers a similar height range to Bzcovac but less detailed information about movement and hardware. I do not treat general brand compatibility as proof of a fit: the display’s mounting pattern, weight, clearance, and the console surface still need checking. Product details supplied for this comparison guide the ranking; I do not claim hands-on testing.

Factors to Consider When Choosing Marine Chartplotter Mount System
I would start by deciding where the screen needs to sit, then check the mount’s fit and installation requirements. The same chartplotter can work well on a tall riser at one helm and feel intrusive on another.Choose a mount style for the helm
A tall riser makes sense when the display needs to clear a windshield frame, controls, or other equipment. Bzcovac and the other adjustable aluminum model extend 18–24 inches, unlike the RAM systems, which keep the screen lower. That height can improve sightlines, but it adds leverage and occupies more space. A swing arm such as WINDFRD’s offers shorter reach and repositioning without the same post-like profile. A short ball mount is a better fit when the screen already sits at a comfortable height.
Match the mounting pattern and ball size
Do not treat a list of supported brands as a guarantee of fit. Check the chartplotter’s mounting holes, the plate’s dimensions, and any adapter requirements before ordering. The RAM C-size and D-size systems are not interchangeable: their 1.5-inch and 2.25-inch balls call for different compatible components. For Bzcovac and WINDFRD, verify the supplied or pre-drilled plate against the device. The second tall riser lists 16 holes, but the available details do not establish that every hole pattern will suit every display.
Use the right load figure
For a moving arm, a static capacity does not tell the whole story. WINDFRD lists 110 pounds static but 22 pounds dynamic; I would use the dynamic rating when judging a display that moves with the boat. The screen, bracket, cables, and any accessories all contribute to the load. The product details do not give comparable capacity figures for the other four mounts, so I would not assume they can carry an equally heavy setup. If the display is large or heavy, check the manufacturer’s limits and account for the leverage created by arm length.
Think through materials and exposure
Salt spray and persistent moisture make material and hardware choices relevant. Several options specify marine-grade or anodized aluminum, with stainless-steel hardware named for Bzcovac and WINDFRD. RAM describes its D-size construction as marine-grade aluminum with a powder-coated finish; the C-size model also uses powder-coated marine-grade aluminum. These details are useful, but they do not remove the need for sensible installation, maintenance, or checking the condition of fasteners over time.
Plan for holes, clearance, and viewing position
Every product here requires a flat mounting surface, and the two RAM options explicitly use drill-down installation. Before drilling, check the underside of the console for wiring and confirm that the base will not block controls, hatches, or a clear view. A tall mount needs more clearance and a stable attachment point than a compact ball mount. Decide whether you need to adjust the screen often, swing it out of the way, or simply set its angle once; that answer separates the multi-joint risers, WINDFRD’s arm, and RAM’s ball mounts.
Frequently Asked Questions
Which mount is best for a chartplotter that needs to sit above the console?
I would start with Bzcovac because its riser adjusts from 18 to 24 inches and its plate, base, and riser each have stated movement. The other 18–24-inch aluminum mount can also lift a display, but its available compatibility and installation details are less specific. Before choosing either, check that the helm has room for the base and that the device plate matches the chartplotter.
What is the difference between the RAM C-size and D-size mounts?
The main difference is the ball system: the compact RAM model uses a 1.5-inch C-size ball and stands 5.225 inches high, while the heavy-duty option uses a 2.25-inch D-size ball and stands 8.125 inches high. Their device fit and compatible components differ, so a chartplotter suitable for one is not automatically suitable for the other. Check the mount pattern and any required RAM components before purchase.
Is WINDFRD’s 110-pound capacity suitable for choosing a chartplotter mount?
I would not use the 110-pound static figure alone to judge a moving swing arm on a boat. WINDFRD also lists a 22-pound dynamic capacity, which is the more relevant stated limit for a load subject to movement. Compare the complete installed load—including display and attached hardware—with that dynamic figure, and check the manufacturer’s guidance for the specific installation.
Do these mounts fit every display from the brands they name?
No. Brand names indicate a stated compatibility range, not a guarantee that every model or mounting pattern will fit. Compare the chartplotter’s hole spacing and weight with the mount plate, ball system, and any listed supported models. This check is especially important for the RAM mounts, which use distinct ball sizes, and for plates whose dimensions are not fully specified in the product details.
Can I install one of these mounts without drilling?
The supplied product details describe flat-surface mounting, and the RAM options explicitly require drill-down installation. I would not assume these systems can attach to a rail or clamp point without an additional compatible adapter. If drilling is not suitable for your boat, check for a purpose-built alternative mounting method rather than relying on an unlisted attachment approach.
Conclusion
My recommendation depends on the helm layout. For a raised display with broad adjustment, I would choose Bzcovac; for a large compatible unit mounted lower with a D-size ball, the RAM heavy-duty system is the better fit. Choose WINDFRD if a short swing arm suits your screen and its dynamic limit covers the complete load, or the RAM C-size model for a compatible chartplotter that should stay close to the console. The second tall riser is worth checking when its 16-hole plate matches your device, but Bzcovac has more fully stated fit and adjustment details. In every case, verify the mounting pattern, available flat surface, clearance, and installation plan before drilling.
