There are earlier photos where he looks very young and quite skinny, then more recent photos where he looks more tubby, less fit. His wedding photos he is starting to look more rotund, perhaps a man who is comfortable in a relationship and started to "let himself go" a bit. Busier in life, less free time to go to the gym and caring less about his appearance. I know non of this fits with his "secret" life but that is how I see it from the outside. He looks less fit, more fat (than he was previously). He told police he had started to run for fitness recently, we can never say whether he had or hadn't, we know certainly that night it was a cover for his other activities but given he said it in interview I would presume it had at least crossed his mind, maybe he wanted to lose some of the timber he had gained.
I've lived in Hull all my life, my grandad was in the merchant navy, I have a good understanding of the tidal nature and currents within the Hull/Humber, the fact they are silt filled and treacherous to navigate, the Hull in particular virtually impossible to do so during low tide periods. I wouldn't have a clue when the next high/low tide was due without searching Google. I don't see any reason why PR would be familiar with the times.
Just as a further point though, the next high/low tides for various places are reported each evening on the local news as part of the weather forecast, but again would he watch or pay attention to local news? Who knows, I don't think its a given he would have knowledge though.
