As an Amazon Associate I earn from qualifying purchases.

These are the fastest ready-to-run electric RC boats on sale in October 2026, ranked by the top speed each maker publishes. Every speed below is the manufacturer’s rating, not a number we measured, and each one links to the page it came from. One-off record builds are left out, because you can’t buy them.

Quick answer: The fastest RTR RC boat by rated speed is the Pro Boat Miss Illinois U-34, rated 70+ mph on 8S. It was in stock at Horizon Hobby as of November 3, 2026, but stock is limited and availability can change. Next is the Pro Boat Sonicwake 36″ V3, rated 60+ mph on 8S and self-righting (in stock at Horizon as of November 3, 2026). Traxxas’s fastest boats, the Spartan SR and DCB M41, are rated 50+ mph on two 3S packs.

Boats are ranked by the top speed the maker publishes. Stock status is from the Horizon Hobby and Traxxas product pages as of November 3, 2026, and can change any day. The U-34 showed limited stock at Horizon, so check its page before you plan around it. Prices change too, so check the current price through the links.

1. Pro Boat Miss Illinois U-34: Highest-Rated RTR Boat at 70+ mph

Availability: The U-34 was in stock at Horizon Hobby as of November 3, 2026 (Horizon Hobby). Stock is limited and availability can change, so check the page before you count on it. If it is not available when you look, the Sonicwake 36″ V3 below is the next-fastest rated boat here.

Horizon Hobby rates the U-34 hydroplane at 70+ mph on 8S, the highest rating of any RTR boat in this guide. It runs a Spektrum 8S 160A Smart ESC and a Spektrum Marine 4685 4-pole water-cooled brushless motor in a 34-inch (864 mm) injection-molded composite hydro hull that weighs 8.14 lb (3.7 kg). You need two 4S 100C LiPo packs with IC5 plugs and a compatible charger (Horizon Hobby).

The U-34 has something the others don’t: a canard you can adjust on the fly from the included DX3 Smart transmitter, plus an emergency full-downforce button that Horizon says pins the nose down to prevent a blow-over at speed. It also uses Pro Boat’s SSL (Strap, Slide, Lock) battery tray and a breakaway aluminum rudder.

Pros: Highest rated speed here; in-flight canard adjustment and a downforce button aimed at the hydro’s biggest risk, blowing over; fully assembled.

Cons: Limited stock at Horizon as of November 3, 2026, and availability can change; not listed as self-righting, so a flip means a retrieve; you still need two 4S 100C packs and a charger.

2. Pro Boat Sonicwake 36″ V3: Fastest-Rated Self-Righting Boat Here

The Sonicwake 36″ V3 is rated 60+ mph on 8S, and it was in stock at Horizon as of November 3, 2026 (Horizon Hobby). Power comes from a Spektrum 74x40mm 4-pole 1350Kv water-cooled brushless motor and a Spektrum 160A brushless marine ESC. The 36-inch (914 mm) ABS deep-V hull weighs 7.9 lb (3.58 kg) and is self-righting. You need two 4S 100C LiPos with IC5 or EC5 connectors and a dual LiPo charger.

Horizon lists several changes for the V3: improved dual water cooling, adjustable trim tabs with two extra tabs, a longer rudder, the SSL battery tray, a breakaway rudder that resets without a hardware change, and a bow that can be replaced with four screws. That last one matters on a 60+ mph boat, because Horizon notes that most damage happens at the bow.

Pros: Fastest rating of the self-righting boats here; self-righting; replaceable bow; batteries load on a tray outside the hull; deep-V handles chop better than a catamaran or hydro.

Cons: Needs two 4S 100C packs plus a dual charger, a real added cost; ABS hull rather than composite; at 7.9 lb it is a lot of boat to retrieve if it stalls far out.

3. Pro Boat Blackjack 42″ 8S: Biggest Catamaran on the List

Horizon rates the Blackjack 42 at 55+ mph and says its motor can produce up to 5.3 horsepower (Horizon Hobby). It was in stock at Horizon as of November 3, 2026. The Specs tab lists a 1350Kv water-cooled brushless motor (Horizon calls it a 4685 in the box contents and a 4985 on the Specs tab, so don’t rely on the can size), a Spektrum Smart 160A high-voltage water-cooled ESC, a Spektrum S904 servo and an SR6110AT telemetry receiver. The hull is 2.5 mm polycarbonate with a molded interior, 42.75 inches (1086 mm) long and 15.25 inches (387 mm) wide, and the boat weighs 8.95 lb (4.1 kg).

For batteries, the Specs tab recommends two 4S 5000mAh 50C+ packs with IC5 or EC5 connectors, while the box list says two 3S-4S 5000mAh 50C packs. Use two 4S packs if you want the rated speed.

Pros: Longest hull of the ranked boats, so it is easy to see at a distance; Horizon calls its molded hull construction much more impact resistant than fiberglass; Smart telemetry through the SR6110AT receiver.

Cons: Slower rating than the smaller Sonicwake 36″ V3; not listed as self-righting, so a flip means a retrieve; Horizon’s own pages disagree on the motor can size and the battery spec.

4 (tie). Traxxas Spartan SR: Fastest Self-Righting 6S Boat

Traxxas rates the Spartan SR at 50+ mph with two 3-cell LiPo batteries (Traxxas), and listed it as available as of November 3, 2026. It runs the Velineon VXL-6s Marine ESC and Velineon 540XL Marine brushless motor, both water-cooled. The deep-V hull is vacuum-formed ABS, 40.8 inches (1037 mm) overall with a 36.5-inch hull, and the boat weighs 5.29 lb (2.39 kg). A flood chamber rights the boat if it flips, and a foam insert in the bow adds flotation.

Traxxas Stability Management (TSM) helps keep the boat straight under hard acceleration and can be set from off to 100% on the transmitter. Traxxas says it needs dual 2S or 3S LiPos (or two 7-cell NiMH packs), and recommends its EZ-Peak 3s Dual charger.

Pros: Self-righting; runs on 3S packs, which are cheaper and easier to find than 4S 100C packs; lightest 50+ mph boat here; TSM.

Cons: 10 mph slower by rating than the Sonicwake 36″ V3; Traxxas High Current Connectors on the ESC, so ARRMA owners with IC5 packs need adapters or new packs; batteries and charger sold separately.

4 (tie). Traxxas DCB M41 Widebody: Same Speed, Catamaran Stability

The DCB M41 is a replica of the Dave’s Custom Boats M41 Widebody catamaran. Traxxas gives it the same 50+ mph rating on two 3-cell LiPos and the same VXL-6s Marine and Velineon 540XL power system as the Spartan SR (Traxxas). The vacu-formed ABS hull is 40.6 inches (1030 mm) long and 10.5 inches (267 mm) wide, and the boat weighs 5.42 lb (2.46 kg). Traxxas listed it as available as of November 3, 2026.

Traxxas says the twin-hull layout gets on plane almost immediately and stays planted at full speed. It also has built-in foam flotation, a quick-release power module, a single-clip hatch, and integrated battery trays for 2S and 3S packs.

Pros: Catamaran stability on smooth water; scale looks with a detailed cockpit; same easy 3S battery setup as the Spartan SR.

Cons: Not listed as self-righting, unlike the Spartan SR; Traxxas High Current Connectors again, so IC5 packs need adapters; batteries and charger sold separately.

Bigger is not faster: the Super Sonicwake 48″

Pro Boat’s biggest self-righting deep-V, the Super Sonicwake 48″ 8S, is 54.8 inches (1392 mm) long and weighs 13.5 lb (6.1 kg), but Horizon rates it at 50+ mph, slower than the 36″ V3 (Horizon Hobby). Buy it for size, not for the fastest rating.

Budget Pick: Pro Boat Recoil 2 V2 26″, Everything in the Box

If you want brushless speed without buying packs and a charger, the Recoil 2 V2 is the one RTR here that includes them. Horizon says its Spektrum 2300Kv brushless outrunner and 100A ESC “can produce 35+ mph”, and the box includes a Spektrum 3S 3200mAh LiPo, an S120 USB charger and an SLT3 radio (Horizon Hobby). It was in stock at Horizon as of November 3, 2026. The ABS deep-V is 26 inches (660 mm) long and weighs 3.3 lb (1.5 kg) without the battery. A self-righting button on the transmitter flips it back over.

Pros: Nothing else to buy; self-righting at the press of a button; small enough for ponds.

Cons: Rated 35+ mph, well behind the boats above; only one battery in the box, so a session ends when that pack is flat unless you buy more.

What It Really Takes to Hit the Rated Speed

Batteries: Every Pro Boat 8S boat here is set up for two 4S packs. Horizon recommends 100C packs for the U-34 and Sonicwake 36″ V3, and 50C+ for the Blackjack 42. The Traxxas boats run on two 3S packs. None of the fast boats include batteries or a charger. See our 3S LiPo guide and RC LiPo battery guide.
Connectors: The Pro Boat boats use IC5 (EC5 also fits on the Sonicwake and Blackjack, per Horizon), the same family ARRMA uses. Our IC5 vs EC5 guide explains what fits. The Traxxas ESCs use Traxxas High Current Connectors.
A dual charger: Two packs per run means a two-port charger, or twice the waiting.
Conditions: The makers don’t publish the conditions behind their boat ratings. Wind, chop and prop choice all change what you see on the water.

Pro Boat is a Horizon Hobby brand, like ARRMA, so ARRMA owners with Spektrum IC5 packs already have part of the setup. To check your own top speed, a GPS meter is the honest way to do it; our GPS speed meter guide compares the options. For the car side of the speed question, see the fastest RC car in the world.
