Glenn Sakamoto from Liquid Salt forwarded this link to some early hull riding during the Malibu Invitational contest in the summer of 1969. The footage is from Hal Jepsen's classic, The Cosmic Children.
The riders are Steve Krajewski, Andy Davis, and Dru Harrison.
Steve is riding his original "Dirt Machine," a 7' x 22'' roundtail Liddle hull. Andy is on a longer, more drawn out Liddle based on Nat Young's 1968 Keyo roundtail, and Harrison is on a Petrillo foiled outline hull, a shape Dru championed during the transition era.
Went to Lennox yesterday as there was supposed to be some 3-5 foot
surf.....I guess a cyclone some months back had moved the sand out and
it has not recovered....Lennox was funky with only a few guys
out........a few more on inside near the beach where Chris Brock still
lives. Checked Broken Head also......nothing on the point and mostly
closed out beach break along Suffolk beaches.......did not even want to
go to Byron as it is very busy and lots of traffic.....beat it back on
the freeway to Kirra for some mid-afternoon waves... see pic...trip ending
Friday.....been a good 5 weeks and surfed about half the days......hope
you are good.....pic Kirra yesterday
Not sure if this has anything to do with hull surfing, but it's pretty cool. One consistent theme here is that all the riders are "going somewhere," as opposed to hovering in one spot and doing tricks. So in that regard, it is kind of hullish.
