Editing Sailing ship (section)

=== Entering and leaving harbor ===
Given the limited maneuverability of sailing ships, it could be difficult to enter and leave [[harbor]] with the presence of a [[tide]] without coordinating arrivals with a flooding tide and departures with an ebbing tide. In harbor, a sailing ship stood at anchor, unless it needed to be loaded or unloaded at a [[dock]] or [[pier]], in which case it might be warped alongside or towed by a tug. Warping involved using a long rope (the warp) between the ship and a fixed point on the shore. This was pulled on by a capstan on shore, or on the ship. This might be a multi-stage process if the route was not simple. If no fixed point was available, a kedge anchor might be taken out in a ship's boat to a suitable point and the ship then pulled up to the kedge. Square rigged vessels could use [[Glossary of nautical terms (A-L)#back and fill|backing and filling]] (of the sails) to manoeuvre in a tideway, or control could be maintained by [[drudging]] the anchor - lower the anchor until it touches the bottom so that the dragging anchor gives steerage way in the flow of the tide.<ref>{{Cite book|url=https://archive.org/details/oceanlifeinolds01whidgoog|title=Ocean Life in the Old Sailing Ship Days: From Forecastle to Quarter-deck|last=Whidden|first=John D.|date=1912|publisher=Little, Brown, & Co|language=en}}</ref><ref name="Harland 1984">{{cite book |last=Harland |first=John |year=1984 |title=Seamanship in the Age of Sail: an account of the shiphandling of the sailing man-of-war 1600-1860, based on contemporary sources |publisher=Conway Maritime Press |location=London |isbn=978-1-8448-6309-9}}</ref>{{rp|199–202}}
