Anyway, here we see Emmanuelle crossing the harbour in one of the old HYF double-decked double-headed passenger ferries (or 雙層雙頭渡輪). Similar in style to the famous Star Ferry.Sadly, I can't tell which specific ferry this was. The film was shot in 1975 and at that time the company had quite a few of these boats in service. According to this rather excellent Chinese Wikipedia article there were 15 ferries, of this style, in service during 1975 (take your pick).
These days the ferry licences have been taken over by New World First Ferry (owned by Henderson Land) but even then the routes in operation are few by comparison, though that's not surprising given the number of cross-harbour and cross-island road routes there are now.
