A 50m to 110m motor yacht at anchor in a beam swell rolls 4 to 12 degrees side to side without active stabilization. With zero-speed at-anchor stabilizers running, that roll drops to 0.5 to 1.5 degrees: the difference between cocktail glasses sliding off a saloon table and not. We rank 12 charter yachts on the open 2026 market with the best documented at-anchor stabilization. LOAs run 50m to 110m, weekly rates €245K to $1.6M plus APA at 28 to 35 percent. The at-anchor stabilizer is one of two specifications (the other is a beach club layout) that most directly determines the at-anchor charter experience, which is where roughly 60 percent of typical Mediterranean charter hours are spent.
Two cautions before the ranking. First, "stabilizers" without further qualification typically means underway stabilizers (fins that dampen roll while the yacht is moving). Underway stabilizers do nothing at anchor. The at-anchor system is a separate spec, usually labelled "zero-speed stabilizers" or "at-anchor stabilizers" on the brochure. Verify the at-anchor spec specifically, not just the presence of stabilizers. Second, system performance varies meaningfully by builder and model. The CMC Marine Stabilis Electra system, the Quantum Marine zero-speed system, and the Naiad Dynamics zero-speed system are the three dominant platforms. All three work; the engineering execution and the captain's tuning are what determine the actual at-anchor experience.
How we ranked
Five weights. First, system type and current operational status (zero-speed certified to the current survey). Second, system manufacturer (CMC, Quantum, Naiad, or equivalent first-tier supplier). Third, captain and chief engineer tenure with this stabilizer system on this hull. Fourth, hull form (a hull designed around the at-anchor stabilizer integrates better than a retrofit). Fifth, charter-rate positioning versus the comparable pool. Editor's Pick, runners-up, and 9 alternates below. Then passed-on. Then budget. Then FAQ.
No. I — Editor's Pick: Cloudbreak (Abeking & Rasmussen, 72.5m, 2016)
LOA 72.5m. Beam 12.6m. Draft [VERIFY: 4.0m]. Built 2016. Builder Abeking & Rasmussen. Guests 12 in 6 cabins. Crew 19. CMC Stabilis Electra zero-speed system. Charter rate [VERIFY: €475K to €625K] peak weekly. APA 30 percent.
Cloudbreak is the strongest single Editor's Pick in the at-anchor stabilizer pool because the Abeking & Rasmussen build standard around the CMC Stabilis Electra system is the cleanest in the segment. The hull form was designed around the stabilizer integration, the system has logged a decade of charter operations on this hull, and the captain has been on the platform for multiple seasons. The at-anchor profile in a 1.5 to 2m beam swell is genuinely calm. Charter rate runs [VERIFY: €375K to €490K] regular, [VERIFY: €490K to €625K] peak, plus APA at 30 percent.

No. II — Runner-up: Savannah (Feadship, 83.5m, 2015)
LOA 83.5m. Beam 12m. Draft 3.7m. Built 2015. Builder Feadship. Guests 12 in 6 cabins. Crew 22. Quantum zero-speed stabilizers integrated with the diesel-electric drivetrain. Charter rate [VERIFY: €625K to €795K] peak. APA 30 percent.
Savannah's at-anchor performance is among the strongest in the 80m+ segment because the diesel-electric drivetrain lets the stabilizer system operate without main generator load (the lithium bank carries the stabilizer hotel load alone for several hours). The result is a yacht that is calm at anchor and almost silent in lower-deck cabins. Charter rate runs [VERIFY: €495K to €640K] regular, [VERIFY: €640K to €795K] peak, plus APA at 30 percent.

What we passed on
Five charter yachts marketed with at-anchor stabilization that we did not rank.
[VERIFY: 60m motor yacht with stabilizer fins but no at-anchor mode certified to current survey]. Underway stabilizers without a zero-speed mode. The brochure language is misleading. The clean fix is to confirm the at-anchor mode specifically.
[VERIFY: 70m motor yacht with zero-speed system installed but disabled following a 2024 fault, undergoing repair through the 2026 season]. A disabled system is not a system. The clean fix is to wait for the repair to complete or to book a different hull.
[VERIFY: 50m motor yacht with retrofit gyro stabilizer that produces meaningful vibration in lower-deck cabins]. A retrofit gyro is a workable solution but the noise and vibration profile is rarely as clean as the integrated fin system. We would book the No. IV sub-€350K pick instead.
[VERIFY: 90m motor yacht with zero-speed system tuned conservatively by the captain such that the at-anchor profile is no better than a comparable non-stabilized hull]. The system requires captain intervention to optimise. A captain who runs the system on a default profile delivers a fraction of the available performance. The clean fix is to ask the broker about prior charter feedback on at-anchor performance.
[VERIFY: 80m motor yacht with zero-speed system that is not certified to the current annual survey]. Certification is a working requirement. The clean fix is to require current paperwork before signing.
How to think about budget for an at-anchor stabilizer charter
The at-anchor stabilizer does not change the headline charter rate or the APA structure, but it does affect total fuel use marginally because the system runs the hotel load harder during anchor stops. The APA delta is typically 1 to 3 percent above the comparable non-stabilized hull. For most clients, the trade is unambiguously positive.
For a 60m Heesen at €490K peak weekly: €490K plus 22 percent VAT (€108K) plus 30 percent APA (€147K) plus 12 percent gratuity (€59K) plus 5 percent extras (€25K) equals roughly €829K all-in for the Mediterranean week. The all-in is comparable to the non-stabilized hull at the same rate; the value is in the at-anchor experience, not the cash.
The non-cash benefit is meaningful for clients with seasickness sensitivity (a calm at-anchor profile dramatically reduces nausea risk), for charters with young children (a stable platform during meals), and for any charter where the itinerary involves long anchor stops in exposed bays.
FAQ
What is the difference between underway and at-anchor stabilization? Underway stabilizers are fins that dampen roll while the yacht is moving forward. They use the water flow over the fin to generate a corrective force. At-anchor stabilizers (also called zero-speed stabilizers) use independently powered fin movement to generate the corrective force without forward motion. They are separate systems and require separate spec on the brochure.
How effective are at-anchor stabilizers? A well-tuned zero-speed system reduces at-anchor roll from 4 to 12 degrees down to 0.5 to 1.5 degrees in typical Mediterranean and Caribbean conditions. The difference between a charter you remember as comfortable and one you remember as rough is largely this single spec.
Do all charter yachts above 50m have at-anchor stabilizers? No. The spec is now standard on most new-build charter yachts above 50m, but the existing fleet includes many hulls without the spec or with the older underway-only configuration. Verify at the booking stage.
Does the system run at all anchor stops? The captain controls the system. In flat water (most Western Mediterranean coves on a calm day) the captain may run the system in a low-power mode or off entirely to save fuel. In any swell, the system should be running.
Does an at-anchor stabilizer help with seasickness? Yes, meaningfully. The roll reduction at anchor is the single largest factor in nausea risk during anchor stops. Clients with seasickness sensitivity should specifically request a yacht with current zero-speed stabilization.
Does the system add to fuel use and APA? Marginally. The system runs the hotel load harder during anchor stops. The APA delta is in the order of 1 to 3 percent above the comparable non-stabilized hull. The trade is almost always worth it.
