Magla i slaba vidljivost na vodi: što učiniti

Posljednja provjera: 14. listopada 2026.

Korak po korak

1. Odmah odredite poziciju

   Kad vidite da magla nailazi, odmah zabilježite poziciju na GPS-u i na papirnatoj pomorskoj karti.[13]

2. Usporite

   Polagano je jedina sigurna brzina u magli. Plovite brzinom koja vam omogućuje da na vrijeme stanete ili skrenete i držite motor spremnim za trenutačni manevar.[27][6]

3. Svjetla upaljena, reflektor podignut

   Upalite navigacijska svjetla, čak i danju, i provjerite je li radarski reflektor postavljen.[11][23][14]

4. Dajte signal za maglu

   Prema COLREGs, motorno plovilo koje plovi kroz vodu daje jedan dugi zvuk (4–6 sekundi) najmanje svake 2 minute; jedrilica daje jedan dugi i dva kratka zvuka. Plovilo kraće od 12 m umjesto toga može davati neki drugi djelotvoran zvučni signal najmanje svake 2 minute.[1][2][3][10]

5. Gledajte i slušajte

   Postavite dodatne članove posade na motrenje i provjerite nose li svi prsluke za spašavanje. Isključite glazbu i neprestano osluškujte motore, sirene, glasove i signale za maglu.[8][15][18][22]

6. Koristite radar i AIS, ali se ne oslanjajte na njih

   Koristite radar i AIS ako ih imate. Imajte na umu da se male brodice možda neće vidjeti na radaru drugih plovila, čak ni s reflektorom.[14][19][28]

7. Čujete signal ispred sebe? Gotovo stanite

   Ako ispred sebe čujete signal za maglu drugog plovila, smanjite brzinu na najmanju kojom još održavate kurs i, ako treba, zaustavite se dok opasnost ne prođe.[7]

8. Maknite se s plovnih putova

   Sigurnom brzinom i stalnim kursom krenite prema plićoj vodi, dalje od prometnih plovnih putova, zatim usidrite i čekajte. Ako morate prijeći prometni pravac, prijeđite ga pod pravim kutom na smjer prometa.[16][9]

9. Signalizirajte na sidru i slušajte kanal 16

   Na sidru plovilo brzo zvoni zvonom oko 5 sekundi najmanje svake minute; plovilo kraće od 12 m umjesto toga može davati drugi djelotvoran zvučni signal najmanje svake 2 minute. Nastavite slušati VHF kanal 16.[5][3][20]

10. Pozovite pomoć ako ste u opasnosti

    Ako mislite da ste zapeli na opasnom mjestu, pozovite pomoć VHF radiom.[17]

Nemojte

• Ne zadržavajte uobičajenu brzinu. Polagano je jedina sigurna brzina u magli.[27]
• Ne pretpostavljajte da vas brodovi vide na radaru ili AIS-u.[19][28]
• Ne puštajte radio i ne dajte da vas ometa razgovor; trebaju vam uši.[22]
• Ne prelazite plovni put ukoso; ako ga morate prijeći, prijeđite ga pod pravim kutom.[9]
• Ne pretpostavljajte da će sunce rastjerati maglu; morska magla može potrajati duboko u poslijepodne.[21]

Prije isplovljavanja

• Prije isplovljavanja: postavite najbolji radarski reflektor koji je praktičan za vaše plovilo.[29]
• Prije isplovljavanja: nosite ispravno sredstvo za zvučno signaliziranje. Plovila kraća od 12 m ne moraju imati zviždaljku i zvono, ali moraju imati neko drugo sredstvo za davanje djelotvornog zvučnog signala.[12]
• Prije isplovljavanja: naučite signale sirenom i zvonom koje morate davati u magli.[26]
• Prije isplovljavanja: nosite kompas i pomorsku kartu kako biste mogli navigirati i ako elektronika zakaže.[25]
