Sky Stinger by Chris Brock This 6 feet 4 inches x 20 inches Brock designed stinger round tail is a very complex shape with various planning surfaces and subtle concaves. 1975. Chris Brock is one of the most innovative shapers in Australia and was influenced by his long-time friend And designer George Greenough. This board reflect many of their shared ideas from the 70s period. Condition-the decks a healthy 8/10 but the bottom has met with a few Lennox rocks over the years and rates a 7/10. Has been kept original with old school ding repairs only. An important example of surfboard design from the mid '70s and displays well.
