Between rebuilding the wheelhouse and sightseeing around Bristol, David started doing the passage plan for the trip up to Sheerness near Gloucester, where we planned to moor for the winter. The combination of swirling mucky
water, the biggest tidal range in the world, winter weather, shortdays and talk of rocks in the channel edges started us thinking that the Severn was best left until summer.
To make the passage safely, you need to sit
out one or two tides at Portishead, in the Severn Estuary, just South of Avonmouth. I took the car down there to investigate the lock entrance and to have a look at the estuary on a fairly windy and decided that the inbound
passage under the bvridges would be fairly calm so long as the wind stayed in the West or SW. A few portishead pictures on a web album here, just look at that water depth gauge, and the stonework rises at least 10 feet above
that
