Båten tar in vatten: så gör du om båten läcker eller sjunker

Senast kontrollerad: 14 oktober 2026

Steg för steg

1. Flytvästar på, slå larm

   Se till att alla har flytväst på sig och slå larm.[1][2]

2. Larma tidigt

   Om båten sjunker, skicka MAYDAY. Om läckan är under kontroll men kan förvärras, skicka PAN-PAN så att räddarna vet i god tid.[3][4][5][6]

3. Hitta läckan

   Om det är säkert, ta reda på var vattnet kommer in. Kontrollera avtappningspluggar och genomföringar i skrovet under vattenlinjen.[7][8][9]

4. Täta eller stäng den

   Försök täta hålet med det material du har ombord för skrovläckor. Om läckan sitter vid en skrovgenomföring med ventil, stäng ventilen.[7][10][9]

5. Pumpa och ös

   Starta länspumpen och ös med öskar eller hink. Fortsätt med det.[11][12][13][14]

6. Sätt kurs mot säkerhet om du kan

   Om båten fortfarande kan gå säkert, styr mot närmaste hamn eller strand som är säker att angöra.[15]

7. Förbered dig på att överge båten

   Innan du lämnar båten, skicka ett nödanrop, behåll flytvästen på och ta inte av dig kläder: ta på dig mer om du hinner. Ha nödsändaren redo.[16][17]

8. Om du hamnar i vattnet

   Aktivera din EPIRB eller PLB. Stanna vid båten så länge den flyter och få upp så mycket av kroppen på den som möjligt. Kryp ihop för att hålla värmen och synas.[18][19][20][21]

Undvik

• Ta inte av dig kläder. Ta på dig mer om du hinner.[16]
• Lämna inte båten medan den fortfarande flyter. Du är mycket lättare att hitta bredvid den.[18][19]
• Vänta inte med att larma tills båten håller på att sjunka. Tidig förvarning kan vara avgörande.[6]

Innan du ger dig ut

• Innan du sjösätter: kontrollera att avtappningspluggarna sitter i.[8]
• Kontrollera kölsvinet före varje tur.[22]
• Ha med verktyg och material för att laga skrovläckor.[10]
• Känn till vilka öppningar i din båt som kan släppa in vatten och hur du stänger dem.[23]
• Ha flytvästar och säkerhetsutrustning lätt åtkomliga, och överväg att skaffa en EPIRB.[24][17]
