Vand i båden: hvad gør du, hvis båden lækker eller synker?

Senest kontrolleret: 14. oktober 2026

Trin for trin

1. Redningsveste på, slå alarm

   Sørg for, at alle har redningsvest på, og slå alarm.[1][2]

2. Tilkald hjælp tidligt

   Hvis du synker, så send en MAYDAY. Hvis lækagen er under kontrol, men kan blive værre, så send en PAN-PAN, så redningstjenesten ved det tidligt.[3][4][5][6]

3. Find lækagen

   Hvis det er sikkert, så find ud af, hvor vandet kommer ind. Tjek bundpropperne og skroggennemføringerne under vandlinjen.[7][8][9]

4. Stop eller luk den

   Prøv at stoppe hullet med de materialer, du har med til lækager i skroget. Er lækagen ved en skroggennemføring med søventil, så luk ventilen.[7][10][9]

5. Pump og øs

   Start lænsepumpen, og øs med en øsekar eller spand. Bliv ved.[11][12][13][14]

6. Sejl i sikkerhed, hvis du kan

   Kan båden stadig sejle sikkert, så sæt kurs mod den nærmeste havn eller kyst, der er sikker at anløbe.[15]

7. Gør klar til at forlade båden

   Send et nødkald, før du forlader båden, behold redningsvesten på, og tag ikke tøj af: Tag mere på, hvis du har tid. Hav din nødsender klar.[16][17]

8. Hvis du ender i vandet

   Aktivér din EPIRB eller PLB. Bliv ved båden, så længe den flyder, og få så meget af kroppen op på den som muligt. Kryb tæt sammen for at holde varmen og være synlige.[18][19][20][21]

Undgå

• Tag ikke tøj af. Tag mere på, hvis du har tid.[16]
• Forlad ikke båden, mens den stadig flyder. Du er meget lettere at finde ved siden af den.[18][19]
• Vent ikke med at kalde, til båden er ved at synke. Et tidligt varsel kan være afgørende.[6]

Før du sejler

• Før du søsætter: Tjek, at bundpropperne er i.[8]
• Tjek bilgen før hver tur.[22]
• Hav værktøj og materialer med til at reparere lækager i skroget.[10]
• Vid, hvilke åbninger i din båd der kan lukke vand ind, og hvordan du lukker dem.[23]
• Hav redningsveste og sikkerhedsudstyr let tilgængeligt, og overvej at have en EPIRB med.[24][17]
