Those of you who can access BBC iPlayer might like to watch Britain on Film, a 30 minute video of boating in the UK way back in the 60s. About half way through there are some clips of Blondie Hasler tweaking his self steering gear, of Jester sailing, and also of Bil King and Galway Blazer creaming along. Not sure of how long it's available.

If you really enjoy old stuff, there appear to be more of the series (non-boating) on You Tube.
