Hi fellow Scottish Aero sailors
I don't have advice on stacking for you but just wanted to say hello and welcome to the class.
I'm based at ELYC in North Berwick where we have a small fleet of 6 Aero regulars. We held the 2019 Nationals with 80 boats just a few weeks ago.
I also sail on the Northern UK Aero traveller circuit, where the socials are as important as the sailing, at excellent venues such as here at North Berwick, Yorkshire Dales SC high in the moors, Ullswater in the Lakes and Filey on the Yorkshire coast, as well as others many and varied!
