Four Yachts

Another boat blip. Lovely night for it.
I know little about sailing but I suppose these are yachts proper rather than the small sailing dinghy from yesterday's blip.
They must have been having some kind of race. A air horn went off and all the boats set off in the same direction.
The strip of land on the horizon is Budden Ness, north east from Tayport. A huge empty area of sand dune used by the military between Monifieth and Carnoustie
