Alkali Fins

Peter 'Mo' Moschogianis has been building surfboards since 1965 on Australia's Gold Coast. He surfed right through the ‘shortboard revolution', constantly experimenting with design.

This single fin is the finished design he used for his boards.

Today it's best suited to a classic single fin surfboard and can be ridden in waves up to six feet.
