This fish hybrid is an updated rebuild of our S-Rail fish. Bills added wings to the S-Rail, lowered the entry rocker, and added a 5th finbox for versatility. The board works ridiculously well ridden as a 5-Fin with a Nubster in the 5th finbox. Sometimes your surfing can get a bit stale and could use a little Re-Hab. This board is the per-scribed "therapy".
