The 775 metre swim attracted overseas and local swimmers. And though the winner was visiting athlete Viktor Kramer, it was a day for the women after that.
Second and third swimmers back to the beach were Genai Walters and local triathlete Harriet Browning.
Among the entrants were a crew of young paddlers who competed in the sprints at Nikao in the morning, before coming back for the Boiler Swim last night.
Funds raised went to Te Are Manu vet clinic.
