So... we took Time Out for her first run today and took the advice to turn left from Aston and travel to Sandon winding hole and come back (no locks).
First mistake... didn't take canopy down and had to stop before first bridge to drop said item, phew.
Second mistake.... the water level! - didn''t give it a thought and then at the next bridge it was way too close for comfort, fortunately we dropped down the wind shield and all was then well, phew.
Third "mistake" ... on our return to Aston we really struggled to moor (windy was sliding us) and ended up mooring across from our berth with the assistance of some very kind people (Malcolm and Gill), third phew!!!
So all in all it was a bit stressful but generally enjoyable and practice and some training will no doubt improve things.
