While I'm on a scow kick, mention must be made of two different scow designs that competed in the Australian ICWDR out of the South Gippsland Y.C. One of the kingpins of the Classic Wooden Dinghy event, Andrew Chapman and family, had two restored Rainbows in the regatta. (Correction: Andrew did the restoration of one "Annie", his son-in-law, Jonathan, a fine craftsman in his own right - music instruments - did the restoration of the other one, "Moonraker".) The Rainbow is an Australian 3.65 meter design that was popular as a junior trainer in South Australia in the 1960's. Andrew sailed one Rainbow with his grand-daughter and, his daughter Trilby, sailed the second one with Andrew's other grand-daughter. I asked Andrew what he thought of the Rainbow scow as a parent/kid sailing dinghy and he was enthusiastic.
"The Rainbow is lovely small boat to sail. It is very forgiving and a lot faster than a Mirror and Heron without using the trapeze and/or large spinnaker. I think it is an ideal boat for an adult and young kid or young teenagers. Trilby and I sailed with each of her two daughters and we plan to introduce them to using a trapeze on a beat and then the trapeze with spinnaker on reaches. We are also putting them on the helm and they enjoy sailing the quicker boat and they are not overwhelmed by the boats size. When they are comfortable using the trapeze and spinnaker trapeze combination the next stage will be the Gwen 12 then Cherub. I think the Rainbow is a very good small boat and it is one that is very easy for home builders to make.Andrew Chapman and grand-daughter in "Annie".

Plans for the Rainbow scow can be found here.
The A-12 scow was Frank Bethwaite's follow-on to his Northbridge Junior scow. Designed to be a higher performance dinghy, the A-12 was longer, 12 feet or 3.65 meters, sported Frank's signature rotating mast and had a trapeze. Neil Kennedy from Nedslocker dug out a November, 1970 issue of the Australian Modern Boating which featured the class when newly introduced. Some photos from that article:
An A-12 scow has shown up at the Inverloch Classic Wooden Dinghy Regatta for the last two years but, as Andrew Chapman writes, in the beginning no-one knew what type of scow it was.
"At the first regatta Andrew Kean sailed the boat as a Moth, with two tone blue sails, because that what it was sold to him as. He did wonder why someone had put a trapeze fitting on the mast. Apparently he never thought to measure the length. He sailed it again in the most recent regatta as an A12 with blue and white sails with a different rig.From the photos it looks like Andrew was able to find a genuine Bethwaite rotating rig and A-12 sail.
The A-12 with the original Moth rig; a blue sail, wooden spars.

For the 2018 regatta, Andrew was able to plug in the correct rig; aluminum rotating mast with a very big sail.
I'm not sure any plans exist for the A-12. None have come forward yet.
George McGee adds more info on the A12. (From a comment I dragged to the main body.)
"I raced an A12 at Northbridge sailing club in the mid seventies. My boat came from Starbord Products with 2 rigs. The first rig was the 85 sq foot two tone blue sail with the over-rotating wooden mast. The second rig was a 65 sq foot two tone sail with a shorter wooden mast. (Not sure of the 65sq foot size). When the smaller rig was used the boat was classed a J12 rather than A12. NSC had a number of A12s and J12s competing on Sundays in the mid seventies.I spent many a happy afternoon on the A12 redefining the term "screaming reach".
