This heavy-duty construction combined with the deep-V hull design enables the Super Sonicwake 48" to cut through waves and chop with impressive stability and control, maintaining composure even during high-speed manoeuvres across challenging water.
• Breakaway Rudder Protection System — The cleverly designed breakaway rudder pivots upward if it strikes submerged rocks, logs or other obstacles, minimising damage to the hull and hardware. This feature lets you explore shallow areas and rocky shorelines with confidence, knowing your boat is protected against one of the most common sources of RC boating damage.
• Underwater LED Lighting System — Super-bright LED lights mounted at the transom illuminate the boat's wake with splashes of colour when running at dusk or night-time, creating a spectacular visual display. This first-ever Pro Boat feature transforms evening boating sessions into an unforgettable experience and genuinely distinguishes the Super Sonicwake 48" from every other RC boat on the market.
• Spektrum DX3 Smart 3-Channel Radio System — The included Spektrum DX3 Smart DSMR 2.4GHz transmitter provides the range, reliability and interference-free operation you need for running on large bodies of water. The on-board battery power level indicator lets you monitor transmitter battery status at a glance, ensuring you always have sufficient power for a safe return to shore. The SR315 DSMR 3-Channel receiver is factory-installed and waterproofed for trouble-free operation.
• Waterproof Receiver Box with Multiple Seals — The dedicated waterproof receiver enclosure protects your most critical piece of electronic equipment with improved sealing on both inside and outside surfaces, minimising any possibility of water ingress. This enhanced protection design keeps the receiver dry through multiple seasons of intensive use, delivering the radio connection reliability essential for large-scale RC boating.
• Quick 1/4 Turn Canopy Latches — Premium quality latches let you remove and reinstall the canopy in seconds without fiddling with traditional screws that can strip or become lost. The quick-disconnect design combined with internal and external seals keeps water out whilst simplifying maintenance and component access.
• High-Quality Aluminium Hardware — Adjustable precision aluminium fittings throughout the boat let you fine-tune ride characteristics and handling to achieve optimum performance in any water condition. Whether you prefer aggressive acceleration or smooth predictable handling, you can dial in exactly the setup you want through careful hardware adjustment.
• Free-Floating Prop Strut Bushing — The innovative bushing design lets you grease the prop strut and shaft with a simple quick-access port, keeping excess grease contained within a designated area. This thoughtful engineering eliminates the mess inside the hull whilst maintaining essential lubrication for long-term reliability and smooth operation.
• Grease Catch System — A dedicated catch area confines excess flexshaft grease in a small removable section, keeping the interior of the boat clean and fresh-looking rather than covered in grease splatter. This practical feature demonstrates Pro Boat's attention to detail and understanding of what RC boaters actually experience during real-world operation.

Technical Performance

The Super Sonicwake 48" delivers exceptional engineering and build quality befitting its status as the largest self-righting RC boat ever manufactured. The heart of the system is a factory-installed Spektrum 4685 950Kv 4-Pole Brushless Marine Motor paired with a Firma 160A Smart Brushless Marine ESC capable of handling extreme power delivery whilst maintaining intelligent thermal management. This potent combination is designed specifically for marine applications, with brushless technology delivering superior efficiency, reliability and lifespan compared to brushed alternatives. The 8S battery configuration (two 4S 5000 mAh 100C LiPo batteries connected in series) provides the substantial voltage and current capacity required to achieve 50+ mph top speeds whilst maintaining consistent power delivery across extended run sessions. The IC5 connector system ensures secure, reliable power transfer without voltage drop issues. The boat measures an impressive 1392 mm in length (54.8 inches), 363 mm in beam width (14.3 inches) and 208 mm in height (8.19 inches), making it genuinely large-scale and highly visible on the water from considerable distances. At 6.1 kg (13.5 lbs) dry weight, the substantial mass combined with the deep-V hull design provides the stability and momentum needed for serious high-speed boating. The ABS plastic hull material offers the ideal balance between weight savings and durability, resisting impact damage whilst remaining light enough for the motor system to achieve its advertised performance targets. Independent water cooling systems for motor and ESC employ sophisticated dual-pickup rudder design to draw cool water continuously during operation, a critical feature for maintaining safe component temperatures during extended summer runs or continuous high-throttle operation. The servo system utilises a Spektrum S905 Standard 40KG 15T Waterproof Metal Gear Servo providing the power and precision needed for reliable steering control at all speeds and conditions. The propeller measures 1.4x50 and is optimised for high-speed performance across the entire throttle range. The 6V 8A continuous BEC (Battery Eliminator Circuit) provides clean, regulated power to all receiver and servo electronics.

Frequently Asked Questions

• Is the Pro Boat Super Sonicwake 48" suitable for beginners or only experienced RC boaters? — Whilst this is a ready-to-run model requiring no assembly, the Super Sonicwake 48" is genuinely best suited for experienced RC boaters. The large size, extreme speed capability (50+ mph) and requirement for large water bodies mean that newcomers to RC boating should consider smaller models first. However, if you're an experienced RC enthusiast with access to substantial lakes or ponds, the RTR format means you can be running immediately after unboxing, making it accessible to anyone with boating experience and appropriate water access.
• What batteries do I need for the Pro Boat Super Sonicwake 48" and where do I buy them? — The Super Sonicwake 48" requires two 4S 5000 mAh 100C LiPo batteries with IC5 connectors, which are connected in series inside the boat to create an 8S (14.8V nominal) power system. These batteries are sold separately and must be purchased as part of your completion kit. The 5000 mAh capacity provides balanced runtime and performance—larger 10,000+ mAh batteries can fit in the included larger SSL trays if you prefer extended run times. You'll also need a compatible charger; RC Model Shop stocks appropriate Spektrum Smart chargers designed specifically for this application.
• What makes the self-righting feature work and how reliable is it? — Pro Boat's self-righting design incorporates clever weight distribution and hull geometry that causes the boat to naturally flip back upright when it capsizes in open water. If the boat flips away from shore, it recovers on its own and continues running at full speed without any intervention required. This feature has been tested extensively and is reliable in typical boating conditions. However, if the boat becomes trapped against a dock or shallow structure whilst upside down, the self-righting feature cannot assist—the design is intended for self-rescue in open water.
• How fast does the Pro Boat Super Sonicwake 48" really go? — The boat is capable of speeds exceeding 50 mph depending on several factors including water conditions, battery freshness, weight distribution and the specific batteries used. Two 5000 mAh 100C LiPo batteries provide balanced performance, but you can experiment with different battery configurations to optimise for either maximum speed or extended runtime according to your preferences. Actual speeds on your favourite water may vary based on wind, water temperature and surface conditions.
• Why is this boat so much larger than other RC boats I've seen? — Measuring nearly four feet in length (1392 mm), the Super Sonicwake 48" is genuinely the largest RC boat Pro Boat has ever manufactured. This substantial size enables several advantages: the self-righting capability would be impractical on smaller designs, the hull provides better stability and control at extreme speeds, and the large-scale proportions make the boat easily visible from considerable distances on large lakes. The size does mean you absolutely must have access to large bodies of water—small ponds will not provide sufficient space for safe operation.
• What's the difference between the Super Sonicwake 48" and the smaller Sonicwake 36" model? — The Super Sonicwake 48" is larger (1392 mm vs smaller dimensions on the 36"), more powerful with the 8S brushless system, and crucially, it's the only model with self-righting capability. Both boats share the same deep-V hull design philosophy and Pro Boat quality standards, but the 48" represents the ultimate expression of that design with enhanced performance, innovative features like underwater LEDs, and the game-changing self-righting system.
• Is the Pro Boat Super Sonicwake 48" ready to run immediately out of the box? — Yes, it's a genuine RTR ready-to-run model with factory-installed motor, ESC, servo, receiver and transmitter. However, you still need to purchase and charge the recommended LiPo batteries and acquire an appropriate charger before you can actually run the boat. Once those items are obtained, you can be on the water within hours of unboxing.
• What kind of maintenance does the Super Sonicwake 48" require? — After each use in fresh water, rinse the exterior thoroughly with clean water to remove salt and debris. The dual water cooling systems require periodic inspection to ensure pickup tubes remain clear. The marine grease supplied should be applied to the prop strut and flexshaft regularly—the dedicated grease catch makes this task clean and straightforward. The waterproof receiver box should be inspected occasionally to ensure seals remain intact. The breakaway rudder should be checked for damage and adjusted as needed. The instruction manual provides detailed maintenance guidance for all components.
