Sketch an irregular line that meets the horizon on the right for the shoreline. With a ruler, place five tall, narrow rectangles next to the longer, horizontal rectangle, as shown. Make sure the tops and bottoms are in a straight line (check with a ruler).
Continue the rowboat by forming the bow or front end with three curved lines. Then arrange two seats with sets of parallel lines. Use a ruler to help get the lines to match. Draw another line parallel to the seats for the stern or rear end of the boat. Extend lines down from the ends of the last line and connect them to make another four-sided figure.
