Croatia Has 223 Marinas for 5,835 km of Coast: Density Compared

Marinas per kilometre of coast: France dominates (28 per 100 km), Croatia surprises (3.8 with its islands, 12.5 without), Greece brings up the rear (1.4). The full calculation across 8 countries.

Counting marinas is not enough: 223 Croatian harbours along 5,835 km of coast is not the same thing at all as 198 Greek harbours spread along 13,676 km of shoreline. Dividing our OpenStreetMap count (ODbL, July 2026) by the coastline lengths of the CIA World Factbook produces a very different map from the raw ranking.

Marinas per 100 km of coast: the table

Methodological notes, and they matter: the French count includes lake and river harbours (inflating its "coastal" density), OpenStreetMap completeness varies by country, and the Factbook's coastline lengths include islands. This table gives orders of magnitude, not metre-accurate measurements.

The Croatian case: 4,058 km of islands change everything

Croatia's coast measures 5,835 km according to the Factbook… of which 4,058 km are islands and only 1,777 km mainland. Set against the mainland alone, Croatia's 223 marinas yield a density of 12.5 per 100 km — comparable to Italy. Croatia's apparently low density is thus an artefact of its geography: a flotilla sailor in Dalmatia finds, in practice, a marina or an organised mooring field at every leg — typically ten to fifteen miles apart — which built the country's charter reputation. The economics behind it are well documented: marinas and charter form continuously growing industries, an engine of European coastal development (Luković, Nautical Tourism and Its Function in the Economic Development of Europe, IntechOpen, 2012, see the study on Google Scholar).

Greece: immense and lightly equipped

With 13,676 km of coast — more than France, Spain and Croatia combined — and 198 recorded marinas, Greece shows the lowest density of the panel: 1.4 marinas per 100 km. It is the country where the anchorage and the small municipal quay remain yachting's basic infrastructure, as we detail in our country-by-country marina comparison. For charter clients the practical consequence is real: in the Cyclades or the Dodecanese, an evening berth is never guaranteed, and planning each leg around a sheltered anchorage is part of the local seamanship.

Turkey and Malta: two opposite models

Turkey illustrates a third model: low density (2.1 marinas per 100 km) but recent marinas built directly at giant scale — the country places 4 ports in our top 15 by capacity, all above 840 berths. Few marinas, but enormous ones, concentrated on the Lycian and Aegean coasts. Malta, conversely, defies its modest density (3.6) through geography: with 197 km of coast in total, no point of the archipelago is ever really far from a harbour.

France: record density, with an asterisk

28.3 marinas per 100 km: France crushes the table, but part of its 1,320 harbours line lakes and rivers, not the sea. Even corrected, French density would remain the highest — the legacy of a coastal development policy we tell in the 2026 French count.

And to sail there?

Marina density shapes cruising style: harbour-hopping in Italy, anchorages under the Cyclades, modern marinas every ten miles in Dalmatia. Boat-Comparator compares rental offers across the 183 destinations of these 8 countries, and our marina directory details every possible stopover — town, capacity, fuel and contact whenever the data records them.
