The answer is Turkey, and it is not close. But the interesting part is not the ranking, it is the size of the gap once you count everything, because the country with the cheapest boat is not automatically the cheapest week.
Here is the comparison done properly: same boat class, same week, with the running costs included.
The Boat Itself
A 45-foot bareboat monohull, mid-June, which is the most common charter in Europe and the fairest basis for comparison.
| Country | 45ft monohull | 45ft catamaran | Fuel |
|---|---|---|---|
| Turkey | €4,000–5,500 | €9,000–13,000 | €1.30–1.55/l |
| Greece | €5,000–7,000 | €11,000–15,000 | €1.40–1.70/l |
| Croatia | €5,500–7,500 | €13,000–18,000 | €1.50–1.75/l |
| Italy | €5,500–8,000 | €13,000–19,000 | €1.75–1.95/l |
| Balearics | €6,000–8,500 | €14,000–20,000 | €1.70–1.90/l |
Turkey is 25 to 35% below Croatia on the boat alone. Greece and Croatia are close enough that the boat price should not decide between them.
Two structural reasons Turkey is cheaper, and neither is about quality. Turkish charter fleets are large, well maintained and often newer than their Croatian equivalents, because the sector expanded later. And the lira means local costs — labour, berthing, food — sit well below the eurozone.
Then the Costs That Change the Ranking
This is where the comparison usually stops and shouldn't. For a week with five marina nights and two at anchor, a 45-footer:
| Turkey | Greece | Croatia | Italy | |
|---|---|---|---|---|
| Berths (5 nights) | €200–450 | €250–500 | €300–600 | €450–1,250 |
| Fuel (typical week) | €180–280 | €200–320 | €220–350 | €260–400 |
| Tourist tax / transit log | €50–120 | €60–150 | €150–250 | €80–200 |
| End cleaning | €120–180 | €150–200 | €150–250 | €180–300 |
| Add-ons total | €550–1,030 | €660–1,170 | €820–1,450 | €970–2,150 |
Two things worth pulling out of that table.
Croatia's transit log is a fixed charge that catches people out. It is a legal requirement covering the boat's cruising permit and crew registration, it is not optional, and it is rarely quoted upfront. Budget €150 to €250.
Greek town quays are the great value proposition in Mediterranean sailing and almost nobody outside the region knows about them. A large number of Greek harbours let you moor stern-to on the town quay for a nominal fee, or nothing at all, with a taverna twenty metres away. You get no water, no power and no marineros, and the night costs about the same as a coffee. A Greek week that leans on town quays rather than marinas closes most of the gap to Turkey.
Italy is the outlier at the top. Sardinia and the Amalfi coast in August will take €200 to €400 a night for a berth, and Porto Cervo is in a category of its own. The boat is mid-priced; the coast is not.
The Total, For a Real Week
Six people, mid-June, 45-foot monohull, five marina nights:
| Country | Boat | Add-ons | Total | Per person |
|---|---|---|---|---|
| Turkey | €4,750 | €790 | €5,540 | €923 |
| Greece | €6,000 | €915 | €6,915 | €1,153 |
| Croatia | €6,500 | €1,135 | €7,635 | €1,273 |
| Italy | €6,750 | €1,560 | €8,310 | €1,385 |
Turkey comes out roughly 27% below Croatia and 33% below Italy on the full week. And that is before food, where the gap widens considerably — a good dinner ashore in Fethiye costs about half what the equivalent costs in Hvar.
The Cheapest Decision Is Not Which Country
Here is the thing that actually saves the most money, and it has nothing to do with geography.
Move the week. The identical boat, from the identical base, in late June or the first half of September, is routinely 25 to 40% below its August price. Not a slightly worse boat. The same one.
The sailing is usually better too. September in the Adriatic is warm water, settled weather and half the crowds. In the Cyclades, June and September sit either side of the meltemi, which blows 25 to 35 knots for days at a stretch from mid-July to mid-August and is the reason experienced charterers avoid the Cyclades in high summer. Croatia is genuinely at its best in July and August, which is the one case where the peak premium buys you something.
A Croatian week in mid-September comes in below a Turkish week in August. The month is a bigger lever than the country.
We covered the timing question properly in Best Time to Book a Yacht Charter, and the last-minute market in Last-Minute Yacht Charter, where boats unsold three weeks out drop 20 to 40%.
The Cheap Options That Are Not Worth It
A boat too small for the group. Six people on a three-cabin 41-footer saves €1,500 and costs you the holiday. Somebody sleeps in the saloon for seven nights. We have never had a client tell us afterwards that it was the right call.
No bimini in August. An unshaded cockpit in the Aegean in August means you eat below and hide from two until five. Boats without one are cheaper for a reason.
Air conditioning that only runs on shore power. Sold as air conditioning, works only on marina nights, absent on the anchorage nights when you wanted it. Either buy a boat with a generator or accept that you do not have air conditioning.
An unknown operator quoting well below the market. Everyone in a given base pays similar prices for similar boats. A quote 30% under the others is information rather than an opportunity, and How to Avoid Yacht Charter Scams covers what to check.
So Where Would We Send You
Cheapest week, full stop: Turkey, Gulf of Fethiye or Göcek, shoulder season. Excellent fleets, spectacular coast, and the lowest total cost in the Mediterranean by a distance. Turkey Sailing has the detail.
Best value that still feels like the postcard: Greece, Ionian, late June. Gentle sailing suitable for rusty crews, short hops, town quays that cost nothing.
Worth paying more for: Croatia in July or August, which is one of the few places where peak season is genuinely the right time to go.
If you want the actual numbers for your group and dates rather than a table of ranges, that is what we do — we quote the same week across three or four bases and send back the total landed cost of each. From £200 per request.
