https://en.wikipedia.org/wiki/Flag_semaphore would have been good if you needed to send arbitrary text.

Naval flags would be higher bandwidth if you could pre-arrange a modest-sized dictionary of the words and phrases you’d need.

https://www.navalgazing.net/Signalling-Part-1 is a good read.

It’s been over two decades but I think the requirement may have been an arbitrary bitstream but if not that, it was likely any of the visible ASCII characters.
