Stanborough Lake.
I arrived at St Albans late morning and had a very informative chat with a delightful chap called Alan who had finished sailing for the day but he very kindly took the time to advise me of some of the water hazards and general information about the lake and the local club.
Moving on to Stevenage in the early afternoon, the water was quite calm and weed free but there was no boating activity for some while until a chap arrived with a fast electric boat that was astonishingly fast and maneuverable for it's small size. He also imparted some useful information but he was only an occasional user of the lake and not a member of any club.
So, all in all, time well spent for me and the family and useful information gleaned.
St. Albans still looks favourite though 😁.
