10th June Exeter Dive In
Exeter & District Model Boat Club Canonteign falls Exeter EX6 7NT
2nd September Bluewater Dive in
Chantry Model Boat Club
Bluewater Parkway, Dartford, Greenhithe DA9
I'm not familiar with these but they may be close to you and perhaps you could give some feedback/ photos etc.
Thanks to everyone who organises these events which help our (rather niche) hobby going. Please also check with the organiser's before you (potentially!) drive several hundred miles.
