There are clear indications for instable rudder behaviour and poor propulsive efficiency if due to a combination of initial keel clearance (KC), squat effects and internal undulations, the ship's keel is in contact with both fluids. The theoretical developments lead to a practical estimation of the conditions in which controllability problems may occur.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Ship behaviour and control at low speed in layered fluids","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:37:00.726867","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1991,"MonPub":null,"DateUpdate":"2008-08-29","DateCreate":"2008-08-29","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":125941,"PubliDate":1991,"Pagination":"[5-1]-[5-9]","XtraPublOfAnaID":null,"ISBN":null,"Volume":null,"Issue":null,"BRefMon":110360,"BRefMonRR":"(1991).
