Full explanation
Roll, the side-to-side motion of a yacht as waves push the hull, is the single largest comfort variable on a yacht.
A yacht without stabilisers at anchor in a swell rolls enough to unsettle a motion-sensitive guest and to move the glasses on the table; a yacht with zero-speed stabilisation in the same swell barely moves. Two stabiliser technologies on modern yachts: (1) Fin stabilisers, underwater fins on either side of the hull that pivot to counter roll, highly effective under way and, on the newer zero-speed systems, at anchor as well. (2) Gyroscopic stabilisers, internal spinning gyroscopes whose angular momentum counters roll, effective at any speed including dead-stopped at anchor. Why stabilisers matter for charter selection in Greece: the Meltemi blows through the central Cyclades on July and August afternoons, and the swell it raises reaches the south-coast lees of Mykonos and the bays of Paros.
Lunch at anchor on a stabilised yacht is lunch; on an unstabilised one it is a matter of bracing.
The Saronic and the Ionian are sheltered, so the fit matters most for a Cyclades week. The questions to ask: does the yacht have stabilisers, are they zero-speed capable, fin or gyroscopic, when were they last serviced.
The fit is a yacht-by-yacht fact stated on each rate card, and this house confirms it with the owner before a name goes on a shortlist.
Eleven motor yachts we represent state stabilisers on their listing: FREEDOM, LADY NATASA, NAYLA, SUMMER FUN, DALOLI, PROJECT STEEL, OAK, RIANA II, NAIA, PAREAKI II and LA PELLEGRINA 1; several of the crewed catamarans state stabilisers too, though two hulls barely roll at anchor to begin with.
Why it matters for UHNW charterers
Stabilisers are the most cost-effective comfort variable in a Cyclades week. Comparing two motor yachts of similar length on the Greek Charter Index 2026, the one with zero-speed stabilisation delivers a noticeably better week in a Meltemi, and this house surfaces the spec before the price.
Worked examples
Stabilised under 28 metres
NAYLA, a Monte Carlo Yachts 80 built 2018 with stabilisers at anchor and under way, EUR 39,500 to 47,500 a week; LADY NATASA, a Ferretti 830 with zero-speed stabilisers, EUR 34,000 to 37,000; SUMMER FUN, an Admiral 101 refitted 2026, EUR 45,000 to 65,000. The Cyclades week for a motion-sensitive party at the quieter end of the band, each rate from the yacht's own card.
Stabilised with twelve berths
SUMMER FUN, an Admiral 101 at 30.8 metres, stabilised both ways and refitted 2026, EUR 45,000 to 65,000; PROJECT STEEL at 34 metres, EUR 55,000 to 67,000; PAREAKI II at 39 metres; LA PELLEGRINA 1 at 50. The family group's answer to an August week in the Cyclades.
Frequently asked
About stabilizers (stabilisers)
Do all luxury yachts have stabilisers?
No. The newer motor yachts usually carry zero-speed stabilisation; older yachts vary, some retrofitted, some with fins that work under way only. Ask for the model and the year, and ask specifically whether the system is zero-speed capable. On the yachts this house represents the answer is on the rate card.
Are stabilisers noisy?
Modern systems are essentially silent in the guest spaces. Some older fin systems and large gyroscopes produce a faint low hum noticeable only when engaged.
Do stabilisers consume a lot of fuel?
Gyroscopic systems run on the generator, so the yacht burns a little more fuel at anchor with them on. The cost sits inside the APA and is small against a week's fuel; the comfort gain is not.
Can I turn the stabilisers off?
Yes, but rarely necessary. The captain may disengage them in flat-calm conditions; most guests want them on whenever there is any swell. A sailing yacht under sail is steadied by the sails themselves, and a catamaran needs none.
