I live by the sea too, and am amazed by the gung-ho attitude people have for the sea.
Most of the time it is just applying a little bit of common sense.
I was paddling with my DD a couple of weeks ago and near us was a little girl (very young, 3 at the most) paddling on her own. A bigger wave knocked her off her feet and her parents were no where near her.
Kids allowed on inflatables while their parents are reading books or news papers right up the beach.
Our local beach gets hit by huge bow waves from big cargo ships regularly, plus the beach is very steep so it gets very deep, very quickly, but there's often young kids swimming or paddling unsupervised
Not that long ago, our RNLI had to get the police out as a bunch of dickheads were pissing around on their slipway and refused to move so they couldn't launch.
My kids have grown up here, they've learnt to sail, they understand that you don't mess about with the sea.
Not everyone will know what to look for and people do get into trouble, but simple shit like staying within reach of your 3 year old isn't rocket science.
There should be a lot more information out there. This year is the first time I remember seeing lots of information about rip tides, etc
