As a Maritime Historian and Terminal Guardian stationed in Sheung Wan, Hong Kong, I've always been fascinated by the what-ifs of our city's transit history. The Hong Kong-Macau route, in particular, has seen its fair share of cancelled vessels, abandoned route proposals, and speculative infrastructure projects. Let's take a journey through the ferries that never were.

In the 1960s and 1970s, hydrofoils were all the rage for high-speed sea travel. Companies like Far East Hydrofoil and Hong Kong & Macao Hydrofoil Company experimented with these sleek, winged vessels to reduce travel times between Hong Kong and Macau. Although they did operate for a while, their service was eventually discontinued due to technical issues and rough sea conditions.

Another experimental technology that made waves in the region was the hovercraft. In the late 1970s, a British-built hovercraft, the SR.N4, was trialled on the Hong Kong-Macau route. While it showed promise, the project was ultimately shelved due to concerns over safety and the high operating costs associated with maintaining the craft's complex technology.

Beyond vessels, there have been numerous proposals for alternative transit methods between Hong Kong and Macau. One of the most intriguing ideas was the proposed undersea tunnel connecting the two territories. First mooted in the 1980s, the concept has resurfaced periodically over the years, with various feasibility studies and proposals being put forth. While an undersea tunnel would significantly reduce travel time and increase connectivity, it remains a costly and complex undertaking that has yet to come to fruition.

These what-ifs offer a glimpse into the complexities and challenges of developing transit infrastructure in the region. They remind us that the history of transportation is not just about the routes and vessels that succeeded, but also about the experiments, proposals, and ideas that, for various reasons, never made it off the drawing board.
