Draw the lines of a vessel 20 meters long, six meters in beam, with a draft amidships of 2.2 meters.  The vessel should have a transom and a rabbeted keel, stem, and sternpost.  There should be a deck, and the location of its outboard edge should be indicated by a dashed line on all three views.  Draw this vessel at scale 1:50, and provide a graphic scale of the proper form.  The drawing will be graded on the basis of accuracy (agreement of points between views; each point out of agreement by more than 0.5 mm is 1.6 points off), completeness, fairness, and neatness.  This drawing should be properly titled, dated, and signed.
