4. Add Nautical Details
Attach four heavy ropes to the bows of the boats with pairs of curved lines. Draw one or two tall poles or radio antennas on each boat. Use thin lines made with a ruler. Add detail to three antennas with short horizontal lines. Make windows and portholes on the cabins with slanted rectangles. Draw a round life preserver on the side of one of the boat cabins using a circle within a circle.
