A reader accuses a boat owner of manoeuvring among swimmers with the engine running and mooring there. The individual case has not yet been officially confirmed. The distance and mooring rules are nevertheless unambiguous.
What is being alleged in Mavarštica – and what has not been proven
On 24 August 2026, the Croatian maritime portal Morski published a complaint from a reader in Mavarštica near Okrug Gornji on Čiovo. According to her account, a local boat owner repeatedly manoeuvres inside a marked bathing zone with the engine running and moors his boat there.
The publication contains no official finding, measurement, penalty or statement from the boat owner. Golden Beach therefore neither names initials nor republishes photographs, character judgements or the allegation as an established violation. The specific case remains unconfirmed, but the rules applying throughout Croatia can still be explained precisely.
The location is Mavarštica on Čiovo – not Mali Drvenik
The reader's complaint places the situation in Mavarštica, or Okrug Gornji, on the island of Čiovo. A widely circulated German blog post instead moved the case to Mali Drvenik, without providing reliable evidence for that attribution.
This is not a minor geographical inaccuracy: Čiovo and Drvenik Mali are different islands with different municipalities and local jurisdictions. Golden Beach therefore follows the location in the original reader report and uses the blog as neither an event source nor a legal source.
Marked and natural bathing areas are not the same in law
Croatia's maritime navigation rules distinguish an organised or delimited bathing beach from a natural bathing area. In a marked zone, the outer limit indicated by buoys or another visible marker is the key reference point for the distances that ships and other craft must maintain.
A natural bathing area may exist without buoys. That does not turn it into an unrestricted manoeuvring area. The regulation contains separate provisions for anchoring, shore mooring and the general duty not to endanger people. Anyone who looks only for a line of buoys therefore misses part of the protection system.
Distances of 50, 100 or 300 metres apply from the bathing-zone boundary
Boats and other craft under 15 metres long must generally remain at least 50 metres from the boundary of an organised bathing beach. Craft from 15 to under 30 metres must keep at least 100 metres away, while ships of 30 metres or more and seaplanes must keep at least 300 metres away.
The distance is measured from the outer boundary of the bathing zone, not merely from the dry shoreline. An ordinary motorboat therefore has no regular passage within the marked area between beach and buoys. A designated boat corridor or an officially regulated access route would need to be clearly identifiable and intended for that exact purpose.

Boats stay outside
The 8-knot rule is not permission to pass through
Within 300 metres of the coast, the maximum speed is 8 knots, and planing may begin only outside that zone. This speed limit does not cancel the special separation distances for bathing zones. Moving slowly through a protected swimming area does not become legal simply because the engine is producing little thrust.
Conversely, the national rule does not impose a blanket requirement to use oars for every approach to a beach. What matters is the distance from the bathing zone, the actual route, mooring and anchoring rules, local orders and the general duty of care. A made-up one-line rule would be easier to remember but legally less accurate.
Mooring to the shore is prohibited in bathing areas
Article 53 of the maritime navigation rules prohibits mooring to the shore in organised and natural bathing areas. Securing a line to land, a rock or another point on the shore within a bathing area is therefore not a permitted way around the navigation rules.
Safety distances also apply when anchoring: an anchor's swinging circle must not come within 50 metres of the boundary of an organised bathing beach. At least 150 metres from the shore must be maintained off a natural bathing beach. In addition, no manoeuvre may endanger people, property, the coast, the environment or other traffic.
An old photograph explains the conflict of uses, not the incident
The photographs in this article date from 2008 and show Mavarčica Bay with swimmers and small boats. They illustrate how different uses occur close together at this location, but document neither today's buoy layout nor the manoeuvre described by the reader.
No visible boat or person shown is connected with the allegation. This distinction matters editorially: a suitable photograph of the location may provide orientation without retrospectively turning a historic leisure image into evidence.
How to report a dangerous situation effectively
If a boat is manoeuvring among swimmers and people are in immediate danger, 112 is the correct emergency number. Anyone who can observe safely should state the bay, time, direction of travel, type of boat and as precise a position as possible. Nobody should enter the water, block the boat or seek a confrontation with the person at the helm.
For a recurring but non-urgent problem, the competent Lučka kapetanija, or its local branch office, is the appropriate contact. Photographs or videos taken lawfully from a safe position may help the authority. Publishing names, registration numbers and accusations on social media first is no substitute for measurement or an official assessment of the individual case.
What can reliably be concluded from Mavarštica
The published reader report is not enough to conclude that a specific person actually violated the regulation. It does, however, describe a realistic conflict of uses for which Croatian law sets clear guardrails: marked bathing zones require separation, shore mooring has no place in bathing areas and slow speed is not a free pass.
For boat operators, the safe routine is simple: identify bathing zones early, give them a wide berth and use only designated access routes. Swimmers should report immediate danger rather than intervene themselves. If an authority investigates the specific case and publishes a reliable finding, this assessment will need to be updated accordingly.
