A boat fire at the Mandurah Marina on Sunday afternoon caused $80,000 worth of damage, but police are not treating the incident as suspicious.
A Department of Fire and Emergency Services spokeswoman said two crews attended the blaze after an initial phone call at 4.43pm.
They found a 28ft vessel on fire, with the cause of the blaze thought to be fuel vapour leading to an explosion during refuelling.
She said the fire was under control by 5.15pm and was fully extinguished by 5.43pm.
The boat was towed away from water close to the Mandurah Offshore Fishing and Sailing Club to avoid damage to other vessels.
A St John’s Ambulance spokeswoman said a woman in her 40s was taken to Peel Health Campus with minor injuries.
