Alimos Marina (Athens)

Alimos, Kalamaki, and Three Thousand Years of the Same Shoreline

The ground itself is older than any of the three marinas. Alimos occupies the site of ancient Halimous, an Attic coastal deme that ancient sources name as the birthplace of the historian Thucydides, and archaeological finds in the area go back to the classical period. The modern marina dates only to the 1960s, when the Greek National Tourism Organisation (EOT) built it as one of its flagship state harbours, using the same contractor, Alpha ATE, that built the Zea basin in Piraeus around the same time - which is likely the root of some of the confusion between the two that this site was warned to avoid.

One institution on the site is older than the marina itself. The Kalamaki Nautical Club was founded in 1947, racing off this beach for more than a decade before EOT's earthworks arrived, and its clubhouse now sits inside the modern marina perimeter. For a reader trying to keep Alimos straight from its neighbours: Flisvos is the closest to central Athens and the most built-up commercially, Zea sits inside working Piraeus next to the ferry port, and Alimos is the furthest out, the largest by berth count, and the one built around a working charter fleet and a founding sailing club rather than a five-star waterfront.

A Forty-Year Concession Rebuilding Greece's Largest Marina

The concession agreement was signed between the Greek State, the state property company ETAD, the Hellenic Republic Asset Development Fund (HRADF) and REDS's marina vehicle, granting the right to use, operate, manage and develop Alimos for 40 years with a mutual option to extend by a further 10. REDS had paid EUR 30 million of the EUR 57.5 million concession price as of the 2026 press coverage of the deal. Ioanna Dretta is CEO of both REDS S.A. and the marina operating company.

The redevelopment itself is priced at close to EUR 100 million, with the core construction work - land reclamation, new pontoons, a five-star hotel, retail and dining space, upgraded nautical club facilities and new public walkways and cycle paths - budgeted at about EUR 50 million and scheduled to run roughly 20 months toward a 2028 completion. Practically, that means an owner booking a berth here over the next couple of seasons should expect some part of the site to be a live construction project, not the finished marina the renderings show.

Alimos publishes a dated, itemised 2026 tariff on its own website - a EUR 137-a-day berth for a 40-metre motor yacht - while its Athens rival D-Marin Zea publishes no rate card for its own marina at all.

Eleven Hundred Berths, and Which Number to Trust

The operator's own figures are the largest and the most repeated: 1,100 permanent berths, with 50 built for yachts over 25 metres, spread across a basin with about 1,170 metres of quay. That is the basis for the marina's own claim, echoed by the Greek Marinas Association and Dockwalk, to be the largest marina in Greece and one of the largest in the eastern Mediterranean. Winter and dry storage adds hard standing for about 350 boats on the operator's account, though the cruising platform mySea separately describes a 60,000 square metre yard.

Independent listings do not all repeat the round 1,100 figure. Noonsite's own entry and a Vastardis Yachting charter base sheet both give 1,080, and a mySea-sourced description gives 1,000 sheltered berths plus 600 dry berths - a materially different way of counting the same facility. None of this changes what a visiting boat experiences, but it is worth knowing that the marina's own count is the most generous one in circulation, in the same way this site found for its Athens neighbours' own published numbers.

Arriving by Sea, and the One Number Everybody Agrees On

Alimos sits inside the Saronic Gulf on the Athens Riviera, sheltered rather than exposed, and the approach carries none of the ferry and hydrofoil traffic that complicates an approach to Piraeus a few kilometres north. The marina's own base-information material lists the entrance lighting as Fl.G.3s9M to port and Fl.R.3s9M to starboard on the way in, and the marina office monitors VHF channel 71 for an incoming call. Beyond that, no independent pilotage or hazard guide specific to Alimos could be found; the general caution for this stretch of coast is the volume of charter traffic converging on and leaving the same basin, particularly at weekend changeover times.

What is genuinely unresolved is how big a yacht the marina can actually take. The operator's own material commits to nothing more than "over 25 metres" for its 50 largest berths. The 2026 published tariff prices monohulls all the way to 45.99 metres, which at minimum tells a buyer the marina invoices boats in that range. Yet Ionian Yacht Charter and a Noonsite-sourced listing both state a flat maximum of 40 metres for the whole facility. A yacht anywhere near the top of that range should get a written answer from the marina office rather than rely on any one of these three figures.

Reserving a Berth, and What It Actually Costs in 2026

The marina's own reservation page routes an application through a berthing-application form and a set of supporting documents, backed by a call centre open long hours six days a week (08:00 to 19:00 Monday to Thursday and Saturday, 08:00 to 20:00 Friday, 08:00 to 18:00 Sunday). There is no public online booking calendar. Where Alimos differs sharply from its Athens neighbours is transparency: it is one of the few marinas this site has researched that puts a dated, itemised price list on its own website rather than requiring a quote request, and it does so with two entirely separate grids - one for monohull and motor yachts, one for catamarans - rather than the area-based formula Flisvos uses.

Worked from the operator's own 2026 list: a 24-metre motor yacht on a permanent berth pays EUR 62 a day or EUR 1,853 a month; a 40-metre motor yacht pays EUR 137 a day or EUR 4,118 a month permanent, or EUR 206 a day if berthed as a transit visitor. A catamaran costs noticeably more for the same length: a 20-metre catamaran runs EUR 100 a day or EUR 3,014 a month permanent, against EUR 50 a day or EUR 1,507 a month for a 20-metre monohull in the same band - the marina's practical answer to a beamy hull, priced by boat type rather than by measuring the beam itself. None of these published figures include VAT.

What Else Is on the Quay, Metered and Unmetered

Power costs a flat EUR 29 a month plus EUR 0.40 per kWh consumed; water is billed at EUR 8 to EUR 35 a month depending on length band, plus EUR 8 per cubic metre with a one-cubic-metre minimum. Waste collection is a flat EUR 50, and lifting or launching costs EUR 100 up to 15 metres or EUR 150 above that. Fuel is not piped to the berth: it is delivered by tanker truck, an arrangement echoed by every charter base information sheet this site checked, from Kavas Yachting to Vastardis Yachting to the mySea-sourced description of the facility.

For anything beyond routine servicing, Kavas Yachting runs the shipyard side of the marina, operating two travel lifts of 70 and 150 tonne capacity plus a hydraulic, remotely controlled self-moving trailer rated to 85 tonnes - genuinely heavy lifting capacity for a Mediterranean marina - and the company states it handles more than half of all the shipyard work bought at Alimos in a given year. A boat needing real repair work, not just an antifoul, has that capability on site rather than needing a passage elsewhere, which is a real point of difference from a marina like Flisvos that has none.

The Sailing Club That Predates the Marina by Twenty Years

The club runs eight sporting sections from its Alimos clubhouse, including open-sea and dinghy sailing, water polo, diving and canoe and kayak, and its water polo team competes in the Greek A1 national league. Its International Yacht Training-licensed sailing school, founded by championship sailor Nikos Nikolopoulos, teaches everything from Optimist dinghies for children to adult yachting qualifications on site. In May and June 2026 the club hosted the ILCA 7 Masters World Championship, its first world championship after two European ones in 2019 and 2024, drawing more than 400 athletes, judges and coaches from over 40 countries, with backing from Greece's Ministry of Development, Ministry of Sports and the Municipality of Alimos.

Club president George Christopoulos summed up the club's own account of taking on that scale of event plainly: "The Kalamaki Nautical Club is ready, once again, to meet the demands of a top event." For an owner or a yacht-racing family, that is a genuine reason to prefer Alimos specifically - a resident competitive sailing culture with 79 years of continuity, rather than a marina that merely has a berth free.

TEPAI, Clearing In, and the Cost the Berth Fee Does Not Cover

TEPAI is charged monthly and by the whole month: a boat that arrives on the 28th still owes for that month in full, and the charge scales with LOA from smaller bands below 12 metres up to the flat EUR 8 per metre rate above it. It is paid online through AADE's own portal, separately from anything owed to Alimos Marina itself, and it applies identically whether the boat is docked at Alimos, at Flisvos, or anywhere else in Greek waters - it is a national tax, not a marina fee.

A non-EU-flagged yacht also needs a Transit Log from Greek customs, valid for six months and extendable to twelve, on top of TEPAI. Clearing in for a foreign-flagged vessel at Alimos runs through the same Port Police, Immigration and Customs process used at any Greek port of entry; the marina's own harbour master position, held as of 2026 by Dimitrios Kalogiannis per his public professional profile, sits within the operating company rather than as a separate port authority function.

Eating Nearby, After Dark, and the Honest Downside

The long promenade along Posidonos Avenue is lined with cafes and beach bars in both directions from the marina gate, and named sit-down options within easy walking distance include Vasilis Taverna (3 Davaki, Alimos), the Italian-leaning Al Dente Kalamaki, Riviera Kitchen & Grill and Bebi's. Evenings along the same strip run to relaxed waterfront bars and cafes rather than a nightclub scene; the marina's own literature also promotes on-site event, photo-shoot and film-production hosting against the Saronic Gulf backdrop, which is a real but different use of the space than a bar crawl.

The honest weaknesses come from people who actually use the place. Diederik Willemsen's long-running Greek-waters sailing guide sailingissues.com calls Alimos "unadorned" next to Athens's other marinas and warns that prices "will go up and up" as the privatised marina develops - a prediction the EUR 100 million redevelopment plan tends to confirm. Named mySea reviewers Sepp Waida and Frank Rudiger both flagged the sanitary blocks as poorly kept for the volume of boats and charter guests passing through, and the same listing notes the marina gets loud and full on summer weekends, partly a function of sitting so close to Athens's main charter-fleet turnover. None of that outweighs the berth capacity, the tariff transparency or the haul-out capability, but a buyer expecting Flisvos-level polish at Alimos will be disappointed.

لمين هو: An owner who wants Greece's biggest working charter base, real haul-out capability and a resident competitive sailing club, and does not mind a marina that is mid-construction through 2028 and plainer underfoot than Flisvos or Zea. Less suited to an owner chasing polish, a quiet basin, or a firm single number for the largest berth available, since the operator's own material leaves that figure open.
