None of the standard mounting arms below are inherently waterproof on their own — the mount holds the iPad in place, but you still need either a waterproof case or a sheltered mounting spot to protect the tablet itself from spray and rain.

The picks, in detail
Scanstrut ROKK Mini Tablet Mount Kit
A purpose-built marine mount system from a dedicated marine-electronics mounting brand, with multiple base options (suction cup, screw-down, self-adhesive) for different helm setups.
- Fits tablets from 5 inches up to 8.25 inches wide
- Part of the modular ROKK Mounting System (compatible with other ROKK accessories)
- Multiple base options: suction cup, screw-down, self-adhesive
- Purpose-designed for marine use by a brand specializing in boat electronics mounting
- Modular system lets you add other ROKK accessories later
- Pricier than general-purpose (non-marine) tablet mounts
RAM Mounts Tab-Tite Universal Tablet Holder
RAM’s spring-loaded cradle system is the most widely used mounting brand in the marine and outdoor space, with holders sized for the full iPad range with or without a case.
- Spring-loaded cradle fits iPads with or without most cases
- AMPS-compatible mounting hole pattern for RAM’s ball-and-socket arm system
- Multiple base options: suction cup, drill-down, rail clamp
- Huge ecosystem of compatible bases, arms, and adapters for any boat layout
- Well-proven durability in marine and off-road use generally
- Not inherently waterproof — pair with a waterproof case for real spray protection
RAM X-Grip Tablet Mount
RAM’s clamping-arm alternative to the Tab-Tite cradle — spring-loaded arms grip the tablet directly rather than sitting in a case-shaped holder.
- Spring-loaded clamping arms fit a range of tablet widths
- AMPS-compatible with the same RAM arm/base ecosystem
- Works with or without most cases
- More universal fit across different iPad generations than a case-specific holder
- Same waterproofing caveat as the Tab-Tite — needs a case for actual spray protection
Tidal Mounts Universal Tablet Clamp-On Mount
A fully adjustable, anodized-aluminum clamp mount marketed specifically for boat cockpits and helms.
- Anodized aluminum ball-joint construction
- Clamp-on design for helm rails and similar surfaces
- Fully adjustable positioning
- Built with boat cockpit and helm mounting specifically in mind
- Clamp-on design requires a rail or edge of the right size to grip
Woleyi Boat Helm Tablet Mount Holder
A budget rail-clamp mount with 360-degree rotation, sized to fit tablets from phone-size up to a 13-inch iPad Pro.
- 360-degree rotation
- Pole/rail clamp base
- Fits devices from 4 to 13 inches
- Lowest price point of the dedicated boat-marketed mounts here
- Wide device-size range in one mount
- Less established brand track record than RAM or Scanstrut
LycoGear Lycan Series Marine Boat Mount
A pole/handlebar-style marine mount built for boat helm rails, covering a wide device range from phones to a full-size iPad Pro 12.9.
- Rail/pole handle-bar clamp base
- Fits iPad Pro 12.9 down to smaller tablets and phones
- Marketed specifically for marine boat use
- Wide device compatibility range in a single mount
- Marine-marketed branding doesn’t mean the tablet itself is protected from water
ARMOR-X Waterproof Case with Mount
This is the piece that actually addresses water exposure directly — an IP68-rated waterproof, shockproof case paired with ARMOR-X’s own mount, turning any of the arms above into a genuinely weather-protected setup.
- IP68 waterproof and shockproof case rating
- Compatible mounting system for pairing with a rail or dash mount
- Available for various iPad models
- The only item on this list that actually waterproofs the iPad itself, not just the mounting arm
- Case adds bulk and typically blocks a slim/lightweight iPad case you might already use elsewhere
Railblaza ScreenGrabba R-Lock Tablet Holder
A dedicated marine-electronics brand’s tablet holder, using RAILBLAZA’s own R-Lock quick-release system to pair with the rest of their boat-mount ecosystem (rod holders, accessory bases, etc.).
- R-Lock quick-release mounting system
- Part of the broader RAILBLAZA marine accessory ecosystem
- Adjustable holder for various tablet sizes
- Useful if you’re already running other RAILBLAZA accessories on the boat and want a matching mount system
- R-Lock bases are proprietary to RAILBLAZA, so it doesn’t mix with RAM or Scanstrut hardware you might already have installed
Arkon Robust Locking Tablet Seat Rail/Floor Mount
A heavy-duty locking mount originally built for commercial/fleet vehicle use, repurposed by boaters for a genuinely rigid seat-rail or floor mounting point.
- Locking mechanism for theft/vibration resistance
- Seat rail or floor mounting base options
- Rated for heavier-duty commercial use
- Locking design is more theft- and vibration-resistant than a standard friction mount
- Designed primarily for vehicle seat rails — confirm it fits your boat’s specific rail or floor hardware
iBOLT TabDock Flexpro Heavy-Duty Floor Mount
A gooseneck-style floor or seat-rail mount built for 7-10 inch tablets in commercial and fleet vehicles, adaptable to a boat’s cockpit floor or rail.
- Gooseneck arm for flexible positioning
- Fits 7-10 inch tablets
- Seat-rail or floor mounting base
- Long gooseneck arm gives more positioning flexibility than a short rigid mount
- Built for the fleet/telematics market, so double-check its base matches your boat’s mounting surface
Buying tips
- The mounting arm and the water protection are two separate purchases — none of the RAM, Scanstrut, Railblaza, Arkon, or iBOLT mounts above are themselves waterproof, so pair one with a waterproof case (like ARMOR-X) or a sheltered mounting location if you’ll see spray or rain.
- Suction-cup bases are quick to install and remove but can fail over time on textured or curved surfaces — a drill-down or clamp base is more secure for a permanent helm installation.
- Measure your iPad’s exact width (with case, if you’ll leave the case on) before ordering, since ‘universal’ cradle-style mounts still have a maximum width they’ll clamp.
- If you’re mounting near the wheel or throttle, prioritize a mount with a locking joint over a simple friction-adjustable one — vibration on a moving boat will work a friction joint loose over time.
