Macroscien said...Did you spot and difference in technique ? or we do the same today?
they do planing gibe, easily, but position on the board is much more backwards
looks like their board is a bit slower too
anything else ?
I have one of those boards but doesn't work with modern rig very well.
That vid was at the height of the rig-forward movement. People were further back towards the tail, and also probably leaning further back the "other way" - ie further back towards the wind. That was caused, I assume, by the fact that rigs had higher drag for their size, and huge booms.
With the mast further forward it was easier to control the rig when the power blew aft in the gusts, and you had more leverage.
As sails improved and booms got shorter, rigs moved aft. By the mid/late '80s there were some pretty good sails around, producing a lot of power for their size - more than modern rigs I'm 99% sure.
I used to sail a forward in marginal conditions compared to most people, but still prefer having the rig further forward in gybes as you get more room for the leg switch IMHO.
Control was more of an issue because of the rigs and the poor fins. The semi-controlled spinout at 3.50 was very, very common. Pro races tended to be sailed in rougher water than many events today and even the pros were less experienced than modern pros, and everyone was still working out techniques. Having the rig further forward reduced spin-out.
Fins these days are SO much better. Rigs are probably heavier due to the battens (a "light" modern 6m weighs twice as much as a One Design 6) and because people use larger flatter sails with better top end, rather than a smaller and deeper sail that has more power for its area but a lower top end and inferior top-end handling qualities.
People were definitely carve gybing, and ironically I'm not sure that more windsurfers can carve gybe well these days than back in the day. However, it's easy to see things through rose-coloured glasses - I used to think that pros may have been gybing better in the '80s (when fleets were huge and sponsorship was flowing, creating a very high standard) but seeing a film by the same guy who did Legends showed that even the pros were slowing down around the gybe marks.
