The marina lock is operated between sunrise and sunset, 7 days a week and is accessible approx ±4.5 hrsHW for vessels up to 1.2m draft, ±3.5 hrsHW for vessels with a 1.5m draft and ±3 hrsHW for vessels with a 2m draft. Its recommended that vessels making for the marina should notify the Lock Control Tower on VHF Ch80, call sign 'Island Harbour' when entering the Folly Reach, or abeam the Folly Inn.
Once upon a time the marina was easily located by the site of a twin funnel paddle steamer 'PS Ride' lying high and dry in the marina campus, which conveniently provided a conspicuous land mark - the steamer is slowly being broken up and scrapped. Today, the best and most hideous land mark for locating the marina is the new Research and Development building of Vestas Blades which lies on the opposite shores to the marina - you simply can't miss it.
There is a holding pontoon outside the lock and a deep water channel is clearly marked by port hand marks. Free flow of water through the lock should be 1 hour before High Water and 2 hours after High Water on Spring tides.
