I just came across this fascinating vid on Erle Pedersons jet bottom boards..an amazing amount of work and he looks like he does the lot start to finish..
Has anyone ever owned/ridden one and if so can you describe how different they are from the norm 
Erle lives up near 1770 one of the the guys that surfs LM with us Jonno has a few of his boards and rates them very highly so much so he drives up there drops the raw materials off and happy to wait up to a year for a board,Erle is retired and goes his own pace very very slow,much work goes into them.
From my view they go OK or it could be Johno 
I had one in the early 90s, 6,2 I think. I think I spent more time on the beach talking about it, I got stopped all the time. I wish I still had it.
He made boards on the northern beaches of Sydney in the 70s and early 80s,a mate had one of his jet bottoms which had the criss cross jet channels from nose to tail,he surfed it really well although it looked a bit slow with all the contours on it but Erle also made some freaky looking cuttlefish designs as well,I don't know what he was on but they were trippy looking sticks
Just found this:In the mid-70s, Erle Pedersen from Cairns and Jick Mebane from Hawaii trade ideas while living at Whale Beach on Sydney's far northern beaches. Before moving south, Pedersen created the 'Kewarra Jet Bottom', devised to maximise energy out of the weak waves that broke at Kewarra Beach neach near Cairns. The Jet Bottom is a beautiful arrangement of curved channels, which, says Pedersen, "busts all forms of water tension."
Erle Pedersen with an early version of his Kewarra Jet BottomThe October 1975 issue of Tracks runs a s**** article, 'U.S.O found in backyard' featuring a startled Terry Fitzgerald holding a futusristic surfboard. The Unidentified Surfing Object is one of Pedersen and Mebane's creations, while an accompanying photo shows four of their boards, one of them being a Kewarra Jet Bottom shaped in August 1975.The Jet Bottom is unlike all other channel bottoms yet it shares the same purpose: to influence water flow under the board and increase performance. Pedersen's contributions are significant and don't end here.and don't end here.

Haven't ridden one however a few of the "Old Salts" in Aggy do and they go all right on them.
See Earle out as well when the surfs up although I hadn't made the connection between the guy and the boards until now.
That last song Agnes Water mornings had me wishing I was there.
I remember walking through Manly Corso back in the early 80s and seeing these on display,I just thought at the time wtf are these things!...
