When it comes to stabilizing your vessel, there’s no shortage of options. But how do you choose between fin stabilizers and a gyroscopic solution like Smartgyro? Let’s break down the differences, advantages, and real-world performance so you can make the best decision for your boating experience.
How Fin Stabilizers Work
Fin stabilizers are mounted externally, beneath the waterline, on each side of the hull. These underwater fins react to the boat’s motion or move actively to generate lift that counters roll. In essence, they “push back” against the forces of waves to keep the vessel more level.
While fins can be very effective at speed, their performance at rest is limited unless they are specialized zero-speed models. Traditional fin systems also require through-hull penetrations to accommodate shafts and seals, and because they extend into the water, they create drag when underway. Over time, they are also more vulnerable to damage from debris, grounding, or marine growth.
How a Gyroscopic Stabiliser Like Smartgyro Works
Smartgyro is a next-generation internal stabilization system. Instead of using underwater fins, it relies on the proven physics of angular momentum and gyroscopic precession. At the heart of the system is a high-speed flywheel, spinning inside a sealed, vacuum-enclosed sphere. When the boat rolls, the gyro sphere tilts, producing torque that counteracts the motion.

Smartgyro units are typically installed inside the engine room, completely self-contained within the hull. With no appendages beneath the waterline, there’s no additional drag, no risk of fouling or impact damage, and no interference with the boat’s handling or hull shape. Most importantly, Smartgyro delivers consistent performance both underway and at rest, making it ideal for cruising, fishing, or relaxing at anchor.
Smartgyro distinguishes itself from fin stabilizers in several key ways:
One of the biggest advantages of a gyroscopic system like Smartgyro is its outstanding performance at zero speed. At anchor or drifting — where fins are least effective and can sometimes create unwanted motion — Smartgyro works at its best, greatly reducing roll and increasing comfort seamlessly. This makes a dramatic difference in beam seas or choppy anchorages, where discomfort and seasickness are most common.
Underway, Smartgyro maintains its stabilizing effect without altering the boat’s natural handling. The system automatically locks the gyro’s counteracting forces during high-speed turns, delivering smoother maneuvering.
Fin stabilizers can be effective for certain hulls and high-speed cruising profiles. But for boaters seeking versatility, reduced maintenance, and strong zero-speed performance, Smartgyro is an exceptional solution.
Whether you’re upgrading during a refit or specifying equipment for a new build, Smartgyro delivers stabilization without compromise.
