Every quote below comes from a yacht owner, named here or identified by their yacht, describing their personal experience with a RotorSwing system. We've translated some from Dutch and shortened where needed, but each reflects the owner's genuine views and experience.
RotorSwing systems are installed on yachts worldwide, in both new builds and refits. Owners are quoted here by name or by yacht, on vessels ranging from Dutch steel cruisers to a 33.5-meter Baglietto.

The endurance benchmark: over 620 hours of open North Sea navigation, Holland to Norway and back, on a single installation.

"We use the boat intensively with the whole family, sail a lot and put her to the test. We knew nothing other than the boat being very comfortable and stable."

Chose RotorSwing after a factory tour in Nuth: "everything looked very neat and professional." Running fault-free since 2021.

"RotorSwing's system is doing its job very effectively, with high performance stabilization, ease of operation, no noticeable noise during day or night at anchor."
"This is my second yacht with a RotorSwing Underway stabilizer system and I am very satisfied. It does its job while cruising perfect."
More than 450 hours in year one on their first Linssen convinced them; their new build got a twin installation.

"The RotorSwing works silently on the onboard electrics, integrates with the electronic engine management, and no awkward modifications to the technical installation were needed."

The owner has a technical background; the deciding factors were system quality and the technical execution.

"The system really works as it should, and is therefore recommendable for lovers of big water, where things can get rough now and then but the yacht is evidently kept stable."
(Fifty years of ocean sailing behind them, now living aboard a motor yacht, cruised to South Brittany.)

"The RotorSwing system was indeed more expensive, but I have absolutely no regrets."
Also his: immediately effective in unexpectedly bad weather, and no particular maintenance required apart from lubricating the shaft.
These owners are a fair sample. The next data point should be your yacht.
