Ringtails are a characteristic sail of Aussie Open Boats, and this video explains exactly what a ringtail is.
I dug up the footage of the Britannia replica being built in 2001-02 and her launch day. It's not quite a how-to video but there are lots of tips to go along with The Open Boat book.
Britannia in Hobart Feb 2017
At the Australian Wooden Boat Festival in Hobart we displayed Britannia on the hard with the big spars up. It looked pretty awesome, even I was impressed at how far from the boat I was when under the tip of the spinnaker pole. So I took a walk around the boat and added comments and the measurements.
Yendys 26 January 2017
Yendys replica steered by Harold Cudmore crosses the line for second in the last heat and second overall in the Australian Championships 2017. The Galloping Ghost Trophy was won by John "Woody" Winning and crew in Aberdare, replica of the original "Galloping Ghost". Irish sailor Harold has been visiting Sydney every Summer for 15 years to sail on the Historical skiffs, and though he's won the Australia Day Regatta several times he hasn't yet cracked the Galloping Ghost Trophy.

Close Finish in Fresh Breeze, Aberdare and Britannia
The video below is from a race on Saturday 26 November 2016 with Britannia on the left and Aberdare on the right racing to the finish in 20 knots of breeze with peakhead spinnakers and ringtails with 3rd rigs. Both these ringtails are of the post 1932 style with triangular heads. Britannia's larger ringtail used with first and second rigs has the earlier shape with the upper batten at roughly the same angle as the gaff with the halyard secured in the centre of the spar as seen in most of the black and white photographs of originals on other Pages. This was taken with an iPhone from the spectator ferry.
