Polynesians in general, especially Hawaiians, and now even the Peruvians are among the very early known surfers. Maybe we could also add Paul the Apostle:
"And falling into a place where the two seas met, they ran the ship aground; and the forepart stuck fast, and remained unmoveable, but the hinder part was broken with the violence of the waves... they which could swim cast themselves into the sea... And the rest, some on boards, and some on broken pieces of the ship. And so it came to pass, that they escaped all safe to land."
There you have it, "some on boards" off the island of Malta around 60 AD. As recorded in Acts 27. Not to mention Jesus walking on water!
