Can I please speculate more? (I'm the kind of person you'll never want to watch a movie / TV show with).
My money's on that he crashed the boat deliberately because he was angry with his then-gf. The others didn't matter - just collateral damage to him.
Both Ms. Beach and his then-gf are blonde. It's 2am, pitch dark and he's inebriated. Small but not entirely impossible chance that he mistook Beach for the gf and actually committed homicide. Or she could just have been really unlucky and knocked unconscious - Beach's bf had a dislocated shoulder.
Daddy Murdaugh saying "she's gone, baby" might actually be a reference the then-gf (she), talking to his wife (baby). Mummy Murdaugh looks like the coddling kind and they usually do not get along well with the gf / wife. Probably blamed her son's episodes on the gf since they seem to have been fighting pretty often.
Fairly easy to picture Mummy Murdaugh in hysterics on the phone and screaming that it was the then-gf's fault, while Daddy Murdaugh is trying to calm her down by reassuring her that he'll put at end to the relationship (also why he kept trying to go into the then-gf's room)
