We taught them how to launch off the 3m and then the 5m platforms (one of theriverswe conducted courses on required a rock launch from about 3m depending on the water level, so we covered that in the pool sessions).
After the formal pool instruction sessions is when we went off the 7.5m and 10m.
Yes, the women always wore one-pieces and never wore bikinis. And yes, on rivers even bathing shorts for the guys werenot always up to the task.
