Update on this thread and the banter on the WhatsApp thread,
Been time limited this week but investigating RGT it looks like you need to subscribe in order to upload a route. I thought I would suss out the free version first to see how it works.
On the subject of a UA, basically the established 20mph challenge for the SA and DA is the exact same for a TA or QA, ie you need to average 20mph from when you get off the boat to get back on. I reckon 2 challenges might qualify for a UA,
1) Just doing 4 laps in a day regardless of time, you would need to stay overnight as if you don't average 20mph for the 224 miles then you can't do the ferry thing in a day.
2) Perhaps a better one would be a 50TA, this would be 3 laps of 50 miles over the Ross so 150 miles and the target speed to catch the ferry would be 18mph. I reckon this would work out harder than a DA.
So there you go George, if you are looking for an Ultra Arran the scene is set ….
