Sjs, there is no way for a woman to be dressed “appropriately” in a pool/beach in front of men. EVEN IF she were fully clothed in the pool (ha!), the wetness would make the clothing too tight.
Squeak, then a father could only go swimming with his daghter until the same age he could sleep in a bed with her.
As far as the pre-6 AM beach idea, that doesn’t help since – even though very infrequent perhaps – a man may pass by the beach that early and see her. (Or in the case of a man, a woman may come by to swim.)
