Let's talk about Hunts - a detailed rundown of their assumed mechanics

I'd like to come back to the full moon thingy.

This information is coming from wikipedia regarding tides:

Approximately twice a month, around new moon and full moon when the Sun, Moon, and Earth form a line (a configuration known as a syzygy), the tidal force due to the sun reinforces that due to the Moon. The tide's range is then at its maximum; this is called the spring tide.

Which would mean full moon isn't the only option.
