On Jan 1st, I went to the pier (just south of Khao Takiap, about 7 km by air south of Hua Hin railway station), and asked people there who confirmed that will be the place where the ferry will dock. On the picture, the ferry looks too big to dock there; or the pier too small, whichever way you see it; or rather the distance between pier and land (Khao Takiap) to narrow.

If it had been running, I would even have taken the ferry to cross over to Pattaya, but with all these delays, I'm out for now (until my next trip to HH or Pattaya, but by then the ferry service might have stopped because they found the water is too wet).
