Make up a waterproof pouch containing any three, five, or seven of the following that seems appropriate: ti leaf; bladderwrack; ash twig; pumice; shark parts; aquamarine; beryl; coral.

Once you have the pouch made, perform the ritual at the shore:

At high tide near and/or on a full moon, anoint the surfboard with ti tree oil. Daub a little on the pouch too, then wear it while surfing. Mark the board with the Chinese symbol for wood since Water supports Wood. Cast a piece of dulse into the sea as an offering to the Gods before heading out on the board for the first time.

Renew the oil at least once a season at a similar time and tide. For continued protection between times, continue to offer dulse each day before surfing.
