In the late 70s early 80s we hired Thunderbolt from Alph Craft. We went under Beccles Old bridge on the Saturday. We moored outside the Waveney House Hotel. On the Sunday morning we woke to an exceptionally high tide which continued rising throughout the day. The river over spilled and flooded the marshes on the opposite bank. We had to move from outside the Hotel and were provided with a safer mooring at Arrow Boats, a little further upstream. With the assistance of Aston Boats, Alpha Craft engineers and a falling tide we managed to get back through the bridge on the following Friday evening.
