raft: [15] The ancestor of raft meant ‘beam, rafter’. This was Old Norse raptr. Not until it got into English, apparently, was it used for a ‘craft made by tying logs together’. (It should not, incidentally, be confused with the mainly American raft ‘large collection, lot’ [19], which is an alteration of Scottish English raff ‘rubbish’ – probable source of English raffish [19]. This too may well be of Scandinavian origin – Swedish has rafs ‘rubbish’.) Rafter [OE] comes from a Germanic source that was probably also responsible for raft. => raffish, rafter
