London Speedboat Rides: Thames Rockets vs the RIB Runs (2026)

Between Westminster and Tower Bridge the river has a speed limit and about thirty other boats in the way, so every fast boat in London spends its first ten minutes behaving itself. Then the bridges run out. East of Tower Bridge the Thames widens into the old docks reach, the commercial traffic spaces out, and the driver puts the throttle down. That is the section people are actually paying for, and it explains why all four fast boats on this river are built to the same shape: a slow, talkative half at the front, a loud one at the back.

I read all four live listings, cross-checked the operators' published route and fleet notes, and worked out what each run costs per minute actually spent on the water. The answers are less obvious than the prices suggest. The most expensive ticket is not the longest ride. The cheapest one is the most expensive hour on the river. And the boat with the best rating in the entire London fleet, across every category, is a fast one.

Which London speedboat ride is best?

The 50-minute Thames Rockets run from London Eye Pier is the best-rated experience on the river at a straight 5.0 across 4,253 reviews, from £69.95. If you want distance instead, the 70-minute RIB to the Thames Barrier at £75.48 goes furthest east. The 20-minute Tower blast at £37.74 is the cheapest way to feel it.

Fast boats sit oddly in the London market. They cost three to four times a sightseeing ticket, they carry a fraction of the passengers, and they still hold the highest ratings on the water. Three of the four score 4.9 or better. Nothing in the sightseeing or dining categories manages that, and the reason is structural rather than magical: twelve passengers per boat on most of these sailings means nobody is standing at the back of a crowd, and the guide is talking to a dozen people rather than two hundred.

The starting prices below are the current floor on each listing. They move with date, demand and how far ahead you book, so treat them as the entry number rather than the quote for your particular Saturday.

There is no separate row for a dedicated private charter, because no per-boat listing is currently live: the Barrier run above is a shared, scheduled sailing, priced per seat at £75.48 with the same free-cancellation terms whether a group books one seat or several.

Two numbers in that table deserve more weight than the stars. The 50-minute Rockets run carries 4,253 reviews, which makes its 5.0 the second most evidenced rating in the whole London fleet after the Westminster to Greenwich sightseeing boat. The sunset run also scores 5.0, but on 249 reviews, so it is a far thinner claim. When two boats look identical on rating, the one with an order of magnitude more people behind it is the safer booking. The same pattern across every category on the river is set out in the ranked cruise comparison.

Where does a Thames speedboat actually go fast?

East of Tower Bridge, and almost nowhere else. Through the central bridge zone the boats run at sightseeing pace with a guide on the microphone. Once the bridges are behind you the river opens out towards Canary Wharf and the Barrier, and that is where the boats reach around 30 knots, with operator pages putting the top end at up to 35 mph.

The geography does the deciding. Central London between Westminster and the Tower is a narrow, busy, heavily bridged stretch with piers on both banks, working river buses on a timetable and a constant sightseeing fleet. Nothing goes quickly there. Downstream of Tower Bridge the channel widens, the piers thin out, and the boats can use the power they were built with.

That means the useful question is not how fast a boat goes but how much river it has to be quiet in first. A 20-minute blast from Tower Millennium Pier starts almost on the boundary, so a high share of its time is spent moving. A 50-minute run from London Eye Pier has three miles of polite cruising to do before anything happens. Both are fine trips, they just spend your money differently.

Here is the eastern run in order, from the point the throttle opens to the turning point on the longest sailing.

The Barrier is the payoff at the far end and the one thing on that list most visitors never see any other way. It sits at Woolwich Reach and it is the reason central London is not routinely flooded on a surge tide, a structure the Environment Agency operates and publishes guidance on. Getting there and back inside seventy minutes is only possible at speed, which is exactly what the long RIB run sells.

Is Thames Rockets worth it?

On the numbers, yes: it is the highest-rated product of any kind on the London river, 5.0 across 4,253 reviews, and the review base is large enough to trust. At £69.95 for 50 minutes it is not cheap, and roughly half the run is sightseeing pace. You are buying a small boat, a guide and one genuinely fast section.

The question comes up constantly because the price sits so far above a sightseeing ticket. The honest framing is that these are different purchases. A £17.20 river cruise sells you an hour of skyline. A speedboat sells you a twelve-seat boat, a driver who talks, and a stretch of river where you get thrown around a bit. People who book expecting the first thing from the second one are the ones who come away unsure.

What reviewers say consistently, across a review base this size, is that the guiding is the surprise. The commentary through the bridge zone is a proper tour, not filler before the fun part, and the run out east covers ground most visitors never reach. Regulars on the route also make a practical point worth repeating: the front seats get the biggest ride and the most spray, the back is calmer, and you can ask which you would prefer when you board.

The operator is not a small outfit. Its published figure is more than 80,000 passengers a year across the fleet, and its turnover was around £3 million in the year before it put a new boat on the water in 2025. That matters mostly for availability: sailings run hourly or better in season, so a missed slot is rarely a lost day. Even so, twelve seats go quickly on a July weekend, and it is worth a moment to check availability for the 50-minute run before you build an afternoon around it.

What is the difference between Thames Rockets and Thames RIB Experience?

Two separate operators with different boats and different piers. Thames Rockets runs from London Eye Pier with five 12-seat RIBs plus a 26-passenger custom boat added in 2025. Thames RIB Experience runs 12-seat RIBs and jet boats from Embankment, Westminster and Tower Millennium piers, and it owns the shortest and the longest runs on the river.

They get confused constantly, partly because both sell "a Thames speedboat" and partly because the boats look similar from a bridge. The differences that actually affect your booking are the departure pier and the run length. If you are staying near the South Bank and the London Eye, one operator is on your doorstep. If your day is built around the Tower, the other one is.

The fleets diverged in 2025. Thames Rockets added a purpose-built 16-metre aluminium boat carrying 26 passengers, driven by twin Volvo Penta engines through waterjets and capable of the same sort of speeds as the smaller craft. Thames RIB Experience went the other way and bought capacity that already existed, taking on two blue jet boats in June 2025 after the previous jet-boat service on the river stopped, and opening at Westminster Pier with an indoor waiting area.

The practical upshot: if you want the longest possible fast run, the Barrier trip is the one, and it is the only listed sailing that reaches the flood barrier and comes back inside seventy minutes. It boards at Embankment or Westminster, which puts it inside walking distance of half the central hotels. Before you commit a date, see what the Barrier run costs on your date, since the longer sailings run less often than the short ones.

How much of each run is spent at speed?

Roughly half on the 50-minute trips, more than half on the 20-minute blast, and the largest absolute chunk on the 70-minute Barrier run. The slow section is fixed by the central bridge zone, so the longer the trip, the higher the proportion spent moving quickly, with one exception: the Tower blast starts east of the bridges already.

This is the single most useful thing to understand before choosing. Everyone compares total minutes and price, and almost nobody works out how those minutes are divided. A boat leaving London Eye Pier has to cover the whole central stretch twice, out and back, at sightseeing pace. A boat leaving Tower Millennium Pier is at the fast water within a minute.

What does a Thames speedboat cost per minute?

Between £1.40 and £1.89 a minute, and the cheapest ticket is the most expensive minute. The 70-minute Barrier run works out at £1.08 a minute, the 50-minute Rockets trip at £1.40, and the £37.74 Tower blast at £1.89. On an hourly basis the blast is the priciest ride on the entire river.

Cost per minute reorders the fast boats in a way the sticker prices hide completely. The instinct is to treat £37.74 as the budget option and £75.48 as the splurge. On the water it is the reverse: the long Barrier run gives you more river per pound than anything else with an engine, and the short blast charges a premium for convenience and a low entry price.

None of which makes the blast a bad buy. Twenty minutes is the right length for a child who will not sit still for an hour, for a group squeezing a boat into a Tower of London afternoon, and for anyone unsure whether they will enjoy being bounced around at all. It is the trial size, priced like one. Where it does not work is as the main event of a day, because you are back on the pontoon before the adrenaline has finished arriving.

Set against the rest of the river, the fast boats are simply a different price bracket. An hour of sightseeing costs £14 to £17.20. An hour on a fast boat costs £64 to £113. That gap is the whole decision, and the ticket-by-ticket price breakdown puts every category side by side if you want to see where the money goes.

Can children go on a Thames speedboat?

On most of the runs, yes, with limits. Operators publish minimum ages and a minimum weight of around 15 kg on the RIB fleet, and the sunset sailing is adults only. Expectant mothers and anyone with back or neck problems are advised against all of them. The exact rule sits on the listing you book, and it differs by trip rather than by operator.

This is the part of the research where the listings disagree with each other, so it is worth reading yours rather than a general rule. The Barrier trips carry the tightest guidance, with recommended minimum ages published in the region of eight to ten depending on the listing. The shorter central runs are more relaxed. The sunset boat rules children out entirely, which is deliberate: it is sold as an evening for adults, with a maximum of twelve aboard.

Weather is the other family consideration and it is simpler than people expect. There is no indoors on a 12-seat RIB. Crews hand out waterproofs, the boats run in most conditions, and rain means a wetter trip rather than a cancelled one. If the forecast is genuinely miserable and the point of the day was the view, a heated sightseeing boat is the better call, and the sightseeing cruise options cover the same landmarks from behind glass.

Which fast run should you book?

Book the 50-minute Rockets run if you want the best-reviewed version of the experience. Book the 70-minute Barrier trip if you want distance and the flood barrier. Book the 20-minute blast if you want the cheapest hit or you are bringing a short attention span. Book the sunset run for an adults-only evening, and the Barrier run for a birthday or work group, up to twelve seats.

Picking by price is the standard mistake. Picking by what you want to be looking at when the engines open up is a much better filter, because the four runs genuinely go to different places and end at different times of day.

The sunset run deserves a note of its own, because it is the one fast sailing that is not really about speed. It leaves London Eye Pier late enough that the return leg happens as the lights come on along the Embankment, which is a genuinely different trip from the same route at two in the afternoon. Twelve seats, adults only, 5.0 across 249 reviews. If an evening on the water is what you are after and you would rather not sit down to dinner, compare it against the after-dark sailings before you book, then check the sunset departure times for your date, since they shift week by week with the sunset itself.

Is a Thames speedboat safe?

The answer is regulatory rather than reassuring. Commercially operated vessels on the tidal Thames must be licensed by the Port of London Authority or certificated by another recognised authority such as the Maritime and Coastguard Agency, and the people driving them need a boatmasters' licence. Neither speedboat operator appears in marine accident or port authority incident reporting for 2025 or 2026.

Start with who is in charge of the water. The PLA looks after the tidal Thames across 95 miles from Teddington to the North Sea, which includes every metre of river these boats use. Vessels working commercially on it have to be licensed by the PLA unless they are certificated by another recognised authority such as the MCA, and the PLA's surveying and licensing teams inspect and licence close to 800 commercial vessels a year.

The person at the wheel is separately regulated. Anyone commanding a passenger vessel on UK inland waters in the relevant categories must hold an MCA boatmasters' licence, and operating without the right one is a prosecutable offence. That is the framework behind the briefing you get on the pontoon before boarding, which covers seating, holding on and what happens at speed.

I checked marine accident and port authority reporting for both operators across 2025 and 2026 and found nothing naming their vessels. Older cases that circulate online involve different boats and different companies, and do not apply here. What that record does not do is make the ride gentle: the whole product is a fast boat on open water, the published guidance about backs, necks and pregnancy exists for a reason, and you will get wet. The full picture of how the fast boats compare with everything else on the water is in the best boat trip in London breakdown, and the timing of a fast run inside a day out is covered in how long a cruise takes.

Common questions

Fast boats are the one category on this river where the rating and the price finally agree with each other, and where the biggest review base in the fleet backs up the highest score. Pick the run by where you want to be when the engines open, not by the number on the ticket. The full fleet, category by category, is laid out on Thames River Cruises.
