I have been digitising a whole lot of old VCR tapes. I post a few here as I finish them.
This one is a clip from a late 80's or early 90's video called Raw Power.
13"-14" Which is 33-36cm in todays metric.
It is interesting that we have found we are faster on slightly wider boards these days. Most of the boards going very fast at Luderitz are in the 39-44cm range.
In some of the shots, you can see some extreme crabbing as well. Boards still do crab of course, but modern assymetrical fins have reduced it significantly.
