Have you ever wondered why some yachts resemble cars with dual controls? Two steering wheels are not a designer's whim, but a thoughtful engineering solution. Let's embark on a journey through the world of marine technology and understand why sailors need this "dual system."
Diving into physics: how heel affects steering
Imagine you are steering through a sharp turn. The car leans, and your view of the road narrows. The same happens with a yacht in strong winds — it heels over, and the sails turn into giant white curtains blocking the horizon. This is where the first advantage of dual steering becomes apparent.
How it works in practice:
- When heeling to the starboard, the port wheel rises above the water level.
- The helmsman moves to the leeward (lower) side.
- Now he sees not the sails, but the open horizon — as if he has moved from the upper deck to the captain's bridge.
Interesting fact: on racing yachts, helmsmen change position up to 30-40 times during a race! It's like a dance — smooth transitions from one side to the other synchronized with gusts of wind.
Safety: the marine version of an airbag
During the 2018 Sydney Hobart Yacht Race, the yacht "Comanche" lost control due to a steering failure. Thanks to the redundant system, the crew was able to continue racing and even finish second. This is not magic — just logic.
Why two wheels are more reliable:
- Mechanical backup: In case of cable or hydraulic failure, there’s always an alternative.
- Risk distribution: The probability of both systems failing simultaneously is like winning the lottery and getting hit by a meteor at the same time.
- Emergency maneuvers: In a narrow strait with strong currents, both wheels can be used for precise control.
For cruising yachts heading on multi-day passages, this is not a matter of comfort but of survival. Imagine your steering jammed 200 miles from shore — with two systems, it would be just an annoying hindrance, not a disaster.
Maneuverability: the marine equivalent of a parking assistant
Modern yachts are like sports cars — wide sterns, streamlined shapes. But this beauty has a downside: the classic steering loses effectiveness. Two compact wheels solve the problem, like a Swiss army knife — elegantly and multifunctionally.
Three levels of improved maneuverability:
- Depth of immersion: When heeling, the leeward wheel goes deeper, increasing "grip" with the water.
- Load distribution: A wide stern creates turbulent flows — two wheels stabilize them.
- Turning radius: In a tight marina, the difference is especially noticeable. Compare:
- A 15m yacht with one wheel: turning radius ≈ 1.5 hull lengths
- With two wheels: ≈ 1 hull length
It's like comparing the turn of a truck and a compact hatchback on a narrow street.
Construction secrets: what lies beneath the deck
Yacht manufacturers are true puzzle masters. Two steering wheels allow them to solve several engineering tasks at once:
Hidden advantages:
- Deck ergonomics: A passage of up to 1 meter remains between the wheels — important during emergency maneuvers.
- Electrical components: Redundant instruments can be placed on each side — from GPS to sounders.
- Shallow water versatility: Draft is reduced by 15-20% compared to classic steering. For the shallow waters of the North Sea (where depth changes reach 10 meters), this is critical.
- Repair logistics: There’s no need to put the yacht in dry dock to replace the steering — work can be done "afloat."
Comparative analysis: choosing a system for the tasks
| Criterion | One wheel | Two wheels |
|---|---|---|
| Cost | 20-30% cheaper | More expensive due to complex mechanics |
| Maintenance | Simple cable system | Requires synchronization of both systems |
| Speed | Optimal for classic models | Gain of 5-7% on modern hulls |
| Dimensions | Width limitations on the stern | Suitable for ultra-wide designs |
| Risks | Single point of failure | Distributed responsibility |
When are two wheels justified? 5 real scenarios
-
"Parking" Monaco style
Imagine a marina where a sheet of paper literally can't fit between the yachts. Two wheels allow you to turn almost in place, avoiding a diplomatic scandal. -
Dancing with the wind
For racing crews, where every movement of the helm affects the position in the race. The precision of the control here is comparable to a surgical instrument. Enroll in our yachting school to master these skills.

Tidal Roulette
When mooring "on the dry" (when the vessel grounds during low tide), a shallow draft protects the rudders from damage. -
Ocean Drifters
In a multi-day crossing of the Atlantic, redundancy of systems is like a backup parachute for a skydiver. -
Photo Hunt at Sunset
Want the perfect shot with dolphins at the side? A smooth turn without heel will keep your glass of prosecco full.
The Other Side of the Coin: 3 Nuances That Sellers Keep Silent About
-
Financial Abyss
The cost increases not only due to the second helm. Add:- A double set of ropes/hydraulics
- Reinforced mountings
- Redundant instrument panels
-
Mechanic's Puzzle
A 1 mm play on one helm creates a 5° error in control. Imagine having to synchronize two independent mechanisms! -
Weight Discrimination
An additional 70-100 kg means either less fresh water supplies or sacrificing a liferaft. Choices have to be made.
Historical Reference: Evolution of Steering Systems
Interestingly, the dual-wheel system is not a modern invention. As early as the 19th century, clipper ships were sometimes equipped with a spare helm. But the real breakthrough happened in the 1990s with the emergence of wide racing hulls.
Paradox: what yachting is created for regattas turned out to be the ideal solution for cruising yachts. Today, 65% of new yachts longer than 12 meters come with dual helms.
Tips for Beginners: How to Master Dual Control
-
Train on a Simulator
Many sailing schools offer VR simulators. Start in the virtual world — save the real rigging. -
Remember the 30% Rule
When turning, first turn the main helm, then engage the second one. Just like in a four-wheel-drive vehicle. -
Control Synchronization
Once a season, check the play using a special inclinometer. A difference of more than 3° is a reason for repair. -
Experiment with Balance
In calm water, try steering with only one helm. You'll understand how they interact.
The Future of Steering Systems: Where Progress is Heading
Manufacturers are experimenting with hybrid solutions:
- Removable Helms: For transitioning from sea to river
- Electric Synchronization: Digital control via sensors
- Emergency Air Helms: Inflatable designs for emergency situations
Perhaps in 10 years, we will see yachts with adaptive helms that change shape like a dolphin's fins.

Conclusion: Is It Worth It?
For a beginner, the difference may seem unclear — like between mechanical and quartz watches. But with experience comes understanding: two steering wheels represent a philosophy of reliability. They provide what cannot be measured in money — confidence.
As an old sailor said in the port of La Rochelle: "One helm is like a bicycle with one pedal. You can ride, but you won't get far." Choose systems that align with your ambitions, and may the wind always be at your back! Learn more about Why are there two helms on a boat.
