Best for competitive training where performance data accuracy is critical. It uses air resistance, which many athletes prefer for consistency and standardized metrics, though it lacks the feel of a water-based machine.
If you’re a **serious rower**, I’d narrow the field to three machines. The key distinction is that “water resistance” and “feels like rowing on water” are **not quite the same thing**. Machine | On-water feel | Training data | Best for --- | --- | --- | ---
If you’re a serious rower, I’d narrow the field to three machines. The key distinction is that “water resistance” and “feels like rowing on water” are not quite the same thing.
| Machine | On-water feel | Training data | Best for |
|---|---|---|---|
| RP3 Model T / Model S | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Closest biomechanical simulation |
| Concept2 RowErg | ⭐⭐⭐⭐½ | ⭐⭐⭐⭐⭐ | Serious training, testing & racing |
| WaterRower Performance / SmartRow | ⭐⭐⭐⭐½ | ⭐⭐⭐⭐ | Actual water resistance + quieter home use |
This is the one I'd buy if your goal is measurable rowing performance rather than simply having a realistic-feeling fitness machine.
Its air flywheel produces progressively increasing resistance as you accelerate it, and the PM5 gives you highly repeatable pace, watts, stroke rate, distance, calories and drag factor, with excellent connectivity to ErgData and other training platforms. Concept2 is also the standard against which a huge amount of indoor-rowing performance is compared.
The important point: it doesn't actually use water, but its resistance curve is remarkably appropriate for rowing and its data is exceptionally useful for structured training.
Why I'd pick it:
If you're doing erg tests for a club, college, masters program or competition, this is the safest choice by far.
This is the unusual one. Instead of keeping the flywheel/frame stationary like a Concept2, an RP3 is a dynamic erg: the resistance unit and seat move relative to each other. That changes the biomechanics of the stroke substantially.
Research comparing ergometers with on-water rowing specifically examines the Concept2 and RP3, and RP3's dynamic motion is intended to reproduce the movement of the rower and boat more faithfully.
The RP3 also provides much more technical feedback than a conventional erg, including stroke-by-stroke analysis and force/power information through its software ecosystem.
For an experienced rower, I'd choose RP3 over Concept2 if:
One caveat: it's not necessarily the best erg-testing machine if your team/competition uses Concept2 scores. Think technical training instrument, rather than universal ergometer standard.
This is the most literal answer to your question. WaterRower uses a water flywheel, so the resistance comes from paddles accelerating through water. It has a very smooth, natural load and is substantially quieter and more pleasant in a home environment than an air erg.
The Performance model adds SmartRow, which is the version I'd consider rather than a basic WaterRower if you're serious about data.
The tradeoff is that WaterRower's data ecosystem isn't as universally standardized as Concept2's. Comparative reviews consistently put Concept2 ahead for standardized performance data and WaterRower ahead for aesthetics, quietness and the water-resistance experience.
I'd choose it if: you want genuine water resistance and a beautiful, relatively quiet machine, but still want substantially better performance tracking than a basic WaterRower provides.
If I weight “accurately emulate rowing + serious data” equally:
The distinction between #1 and #2 is important: RP3 is closer to the movement of a boat; Concept2 is closer to the universal language of rowing performance. RP3's own documentation makes the same dynamic-versus-static distinction, while research is actively comparing those two designs with on-water rowing.
If you told me “I race and want one machine in my home”, I'd buy the Concept2 RowErg.
If you told me “I already have a Concept2 and want the best machine for translating indoor work to boat technique,” I'd add an RP3.
If you told me “I want actual water resistance, a beautiful machine, and good—not necessarily industry-standard—data,” I'd get the WaterRower Performance with SmartRow.
And I would not choose a magnetic-resistance rower simply because its screen has more features. For a serious rower, the resistance mechanics and data integrity matter considerably more than a giant touchscreen.

If you’re a **serious rower**, I’d prioritize two things: **a resistance curve that behaves like rowing rather than generic cardio equipment**, and **data you can actually use for structured training and comparison with other rowers**. ### My ranking - **Concept2 RowErg** - $1,050.00 (REP Fitness)
If you’re a serious rower, I’d prioritize two things: a resistance curve that behaves like rowing rather than generic cardio equipment, and data you can actually use for structured training and comparison with other rowers.
Bottom line: If your priority is training performance, racing, erg testing or coaching data, this is the one I'd buy. 2. WaterRower Performance — best if authentic water resistance is non-negotiable
Bottom line: Choose this if water feel matters more than standardized erg scores. 3. WaterRower Original + S4/Bluetooth monitor — best simpler water rower
There's a slightly counterintuitive answer here:
The machine that most closely resembles water isn't necessarily the machine that most accurately represents rowing performance.
A WaterRower literally uses water, so it wins on physical sensation. But a Concept2's air flywheel and PM5 provide exceptionally consistent, measurable resistance and data, which is why serious rowing programs use it for standardized testing.
So I'd make the choice this way:
| Your priority | Best choice |
|---|---|
| Competitive/club rowing | Concept2 RowErg |
| Most authentic water feel | WaterRower Performance |
| Water feel + attractive home furniture | WaterRower Original |
| Classes, games & connected workouts | Aviron Strong |
| Most useful training data | Concept2 PM5 |
| Quietest/natural-feeling experience | WaterRower |
My recommendation for a serious rower: buy the Concept2 RowErg unless you specifically want actual water resistance. It's the better training instrument, even though the WaterRower is the better water simulation. The PM5/ErgData ecosystem and standardized scores are a major advantage that becomes increasingly valuable as your training gets serious.
If you tell me your budget and whether you're training for 2K/5K/6K racing, masters rowing, or general on-water performance, I can narrow this to the best 2–3 machines for your use case.
For a serious rower, finding a machine that marries the organic, fluid catch-and-resistance profile of moving water with telemetry precise enough for structured ergometer training (splits, power curves, stroke-by-stroke analysis) can be tricky.

For a serious rower, finding a machine that marries the organic, fluid catch-and-resistance profile of moving water with telemetry precise enough for structured ergometer training (splits, power curves, stroke-by-stroke analysis) can be tricky. Traditional water rowers feel great, but standard monitors have historically lagged behind the gold-standard data accuracy of air-resistance ergs like the Concept2 Go to product viewer dialog for this item..
The top choices that successfully bridge this gap—providing authentic water resistance alongside truly robust workout data—include the following:
Why it fits: This version specifically addresses the data-limitation of traditional wood-and-water rowers. It is built with a patented Power-Pulley system and integrated strain gauges/optical sensors that individually calibrate and analyze your force output.
The Data: Instead of guessing or relying strictly on standard paddle-rotation algorithms, it maps out a real-time power curve showing how your power and leg drive are distributed throughout the stroke. It connects seamlessly via Bluetooth to the WaterRower Connect App or third-party apps like EXR and Peloton for precise metric tracking.
Why it fits: FluidRower Go to product viewer dialog for this item. uses a patented Twin Tank system with adjustable fluid resistance (allowing you to change the water catch resistance mid-row via a dial, unlike single-tank rowers where resistance is solely pace-dependent).
The Data: Their upgraded digital console auto-detects the tank resistance level you've selected, syncing it with stroke rate, 500m split, calorie burn, and heart rate telemetry. It provides a very tight correlation between physical effort and digital feedback, and interfaces cleanly with apps for structured interval tracking.
Why it fits: If you want the physical build, aesthetic, and water dynamics of a classic WaterRower frame coupled with a high-definition, data-centric interface, Ergatta Go to product viewer dialog for this item. is built around calibrated performance.
The Data: It uses the same genuine water-resistance feedback loop, but maps your data into calibrated, personalized "zones" based on a baseline workout. Rather than mindless pulling, it drives serious training via interval programming, race simulations, and continuous tracking of split times, wattage, and stroke efficiency.[1]

For a **serious rower**, I’d prioritize *rowing-specific resistance and standardized performance data* over a big touchscreen or guided classes. On that basis, there are three standouts: - **Concept2 RowErg** - $1,050.00 (REP Fitness) - **WaterRower Original Series** - $1,630.60 (Sweatband)
For a serious rower, I’d prioritize rowing-specific resistance and standardized performance data over a big touchscreen or guided classes. On that basis, there are three standouts:
| Machine | Water-like feel | Workout data | Best for |
|---|---|---|---|
| Concept2 RowErg | ★★★★☆ | ★★★★★ | Serious training/testing |
| WaterRower Original | ★★★★★ | ★★★☆☆ | Most natural water feel |
| Aviron Strong | ★★★★☆ | ★★★★☆ | Connected training + versatility |
Concept2 RowErg
If your definition of "serious" includes 2K/5K/6K testing, comparing splits with teammates, structured intervals, or eventually racing on-water, this is the one I'd buy.
The RowErg uses an air-resistance flywheel rather than an actual water tank, but its resistance is exceptionally predictable: the harder you pull, the more resistance you create. More importantly, the PM5 provides pace, watts, stroke rate, calories, drag factor and other performance information, while ErgData and the Concept2 Logbook let you track workouts over time.
It's also the benchmark against which indoor-rowing performance is commonly compared. Concept2 specifically emphasizes the PM5's consistent, comparable measurements across machines.
Why I'd choose it: for a competitive rower, data comparability beats a prettier water tank. Your 2K on a Concept2 means something to another Concept2 rower.
WaterRower
If by "emulate water resistance" you mean literally use water as the resistance medium, this is the more obvious choice.
The tank-and-paddle system produces the characteristic accelerating resistance and water sound of a rowing shell. It's exceptionally smooth and arguably the most satisfying machine for simply rowing.
The compromise is the monitor. Its S4 system gives you useful rowing metrics, but it's not in the same league as the PM5/ErgData ecosystem for standardized training data and competition-style benchmarking. Independent comparisons likewise favor Concept2 for data and WaterRower for feel.
Choose it if: realistic water sensation is more important to you than having the industry's most standardized performance data.
The Aviron Strong Series combines air and magnetic resistance, with a large touchscreen and extensive connected training/game features.
It's considerably more sophisticated as a home fitness platform than a traditional erg, but that's also why I wouldn't put it ahead of the Concept2 for a competitive rower. You're buying an interactive training system rather than a standardized ergometer.
Choose it if: you want serious exercise capability but also want games, coaching, entertainment and a modern connected experience.
If you actually row on the water, take a close look at the Concept2 Dynamic RowErg.
It's specifically designed for on-water rowers and attempts to reproduce the dynamics between the athlete and racing shell, with the machine's moving components responding to the stroke. Concept2 explicitly recommends it for people who row on the water. It still uses the PM5, so you retain excellent performance data.
For an experienced rower, I'd actually rank it:
Dynamic RowErg > standard RowErg > WaterRower > Hydrow/Aviron
if your primary objective is transfer to on-water rowing + rigorous training data.
My recommendation for you: if you already identify as a serious rower, I'd spend the money on a Concept2 RowErg (or Dynamic if you row on the water) rather than paying extra for a touchscreen. The PM5 + ErgData combination gives you the kind of longitudinal, comparable data that's genuinely useful for training.

For a serious rower, finding a machine that balances the authentic fluid dynamics of a water tank with precise, actionable ergometer data can be tricky. Traditional water rowers offer an incredible, organic "catch" and resistance curve that mimics a shell on open water, but many fall short on advanced metrics (like accurate watts, split trends, and stroke-by-stroke analysis).
The top options that successfully bridge the gap between true water-resistance feel and robust, high-level workout data include:
Add to list Specifically engineered for competitive rowers and enthusiasts, this model upgrades the classic WaterRower frame with specialized PowerPulley technology . It transmits precise, ergometer-level power and stroke data wirelessly via Bluetooth to the subscription-free WaterRower Connect App , providing accurate wattage, heart rate, and 500m split metrics while retaining the signature smooth water flywheel and wider handle.[1]
Add to list Built upon the reliable WaterRower physical chassis, the Ergatta Rower pairs the natural, lapping water resistance with a high-tech, game-based digital platform. For serious rowers who want robust data, it calibrates to your personal fitness level and translates your real-time stroke rate, wattage, and total output into interval-driven workouts, structured training plans, and competitive or calibrated races.
Add to list While it uses an innovative Aquafeel technology rather than an actual enclosed water tank, it is worth noting for serious or competitive on-water rowers. It provides a remarkably realistic, fluid on-water resistance profile at the catch, but adds a dual-mode feature (Cardio vs. Power mode) that lets you dial in heavy magnetic resistance to simulate rowing uphill or through a stronger load, backed by elite-level telemetry and data tracking via the Skillrow app.

For a serious rower, I’d narrow the field considerably. If your priorities are on-water feel + high-quality training data, these are the standouts:
This is the strongest choice if you specifically want water resistance rather than merely an erg that happens to feel good.
Verdict: If you insist on water resistance and want serious performance monitoring, this is my first pick.
RP3 Rowing makes something fundamentally different from a conventional erg.
The RP3 Model T is a dynamic rower: rather than keeping the athlete and seat rigidly fixed like a conventional erg, the system allows movement that is intended to reproduce the dynamics of a boat. RP3 describes its design as simulating a lightweight racing shell floating on water.
Verdict: For rowing mechanics, I'd choose RP3 over a WaterRower. For water-resistance specifically, look at the RP3 Aqua.
This is the choice I'd make if data, benchmarking and serious training matter more than literally having water in the tank.
The RowErg uses air resistance rather than water, but its PM5 monitor is exceptionally good for structured training. It provides consistent, comparable results across machines and locations, which is why Concept2 scores and rankings have become such a standard in rowing.
You get:
Concept2's free ErgData app adds additional real-time metrics and automatically stores workouts.
Verdict: It doesn't replicate water resistance as closely, but for serious erg training, it's arguably the benchmark.

For a serious rower, the holy grail of indoor training is finding a machine that replicates the dynamic, fluid catch and resistance profile of an actual shell on the water, while ditching the notoriously vague metrics that plague traditional water rowers.
Unlike air ergometers (like the Concept2) which use a linear resistance curve, water resistance scales naturally with your effort (fluid drag via a paddle in a tank), matching the real-world physics of moving a boat. However, standard water rowers estimate wattage based on paddle speed and tank volume, which can vary and makes true data analysis difficult.
The top options that successfully bridge the gap between authentic water dynamics and robust, lab-grade training data include:
Add to list The gold standard for data-obsessed rowers who want genuine water feel. You can purchase a standard wooden WaterRower Go to product viewer dialog for this item. and retrofit it with the SmartRow Power Meter , or buy it built-in. SmartRow Go to product viewer dialog for this item. replaces the standard pulley with an intelligent electronics module that measures absolute force and actual stroke length . It renders a true force-curve , tracks watts per kilogram, outputs absolute wattage independent of the water level in the tank, and syncs seamlessly with apps and Strava.[1][2]
Add to list Equipped with patent-pending PowerPulley technology, this model is built specifically for competitive rowers . It uses integrated strain gauges and optical sensors in the forward riser to transmit ergometer-precise training data wirelessly via Bluetooth to the WaterRower Connect app, visualizing your stroke profile and power output with high precision without needing a retrofit.[1][2]
Add to list FDF machines are well-regarded in commercial and serious rowing setups because of their patented adjustable fluid resistance . Unlike single-tank water rowers where resistance is purely governed by your speed, FDF allows you to mechanically dial the resistance level (from feather-light to heavy crew boat) inside the tank while maintaining a consistent catch and resistance curve throughout the entire stroke length. Paired with their upgraded dual-tag Bluetooth monitors, they deliver accurate heart rate tracking and split/wattage data.
