Prepare your boat with sucking any water and sludge from the bottom of the fuel tank. Service the engine and clean fuel filters check fan belts and have spare filters and belts. Anchor must be set out so you can deploy it if necessary and secure the bitter end to the boat, it is no use under the bed. Life jackets for all crew. You will leave Tarleton river lock before high tide and push against the tide down the Douglas and with the tide up the Ribble to Savick brook. Choose a neap tide and avoid the high spring tide. The Lancaster is a lovely area to visit. There is a width restriction in Savick brook.
