The usual advice for a chain road in relatively sheletered water is 3:1. The average tidal range at Felixtstowe is about 3.5 metres or 12 feet. The tidal currents in the estuary are reported to be between 1 and 2 knots depending on the location and whether it is neap or spring tide.
Would that be able to cause the Goblin to drag its anchor? Maybe especially if Jim Brading had not let out the full scope because he was only planning to be gone for a short time, or if there were other boats or obstacles close by which would restrict his swinging room.
