I trust you are referring to the insignia looking like a pair of sunglasses rather than there being a fat B on the sail and another fat B****** in the boat
That be the Avonmouth bridge! I used to live in Pill, just opposite Shirehampton SC, and I confess I went to Bristol Avon to go sailing. I never was a big fan of mud!
I thought I recognised it! Until very recently I was a zummerzet lass and that bridge was my crossing back to sanity. I worked in Brisstle for a while too, but I'm afraid I did my sailing at the somewhat snotty Chew Valley Lake SC.
The unsalubrious bits of Wiltshire, as well as Swindon, were Melksham and Trowbridge, The only good thing about living in these two was their proximity to Shearwater!
