Two things here:
Who said there was bad weather? The METAR showed CAVOK earlier in this thread, though it was a bit windy. More likely the vessel experienced a stormy sea during rescue operations.
Who said there was a go-around? It was said earlier, all was normal, aircraft transferred to TWR, then no contact. A go-around - given CAVOK - would certainly have been seen from the Tower. I would think, the aircraft may never have come that close to the Tower so it could be seen. Yes seen, with eyes. I am not talking about radar.
Urban legends.
