The caption says: "Students learn the advantage of a safe leeward position as the Alberg 35 drives through the lee of the fast moving Triton". Ardell is still around on the west coast...but I don't think they have a sailing school. I emailed them a scan of some of their ads and got an email back from a guy who was on one of the boats when they were shooting them!!
Another Ardell advert.
Pearson ad from 1964.
