I was a member of Horning Sailing Club when I was (much) younger. It was a very friendly place to sail with a great variety of racing , from around the cans in the broad, to laps on the river close to the club, to full scale down river races with a stop for lunch at Thurne and Acle. I have just joined again, and found found same friendly, interesting place to sail. We'll worth considering if you are new to sailing or coming back to it.
