Let's draw a tugboat
Treat this as one small practice round: build the subject lightly, notice the shapes, then darken only the lines that help the finished sketch.

01
Block in the hull
Draw a long shallow boat curve, then add a second lower curve to make the rounded hull. Place a light box guide where the cabin will sit.
Sketch tip: Keep the bow and stern tips level. A calm, even hull makes the rest of the tugboat easier to stack.

02
Stack the cabin
Set a boxy cabin on the deck line and cap it with a soft rounded roof. Let the roof overhang the cabin just a little.
Sketch tip: Use vertical cabin sides. If they lean too much, the tugboat starts to look like it is tipping.

03
Refine the boat outline
Darken the bow, stern, deck edge, cabin sides, and roof, then add a short smokestack behind the cabin.
Sketch tip: The smokestack should be shorter than the cabin. That keeps the drawing friendly instead of top-heavy.

04
Add the windows
Draw small round portholes along the hull and simple rectangular windows on the cabin.
Sketch tip: Space the portholes like beads on the hull curve. They do not need to be perfectly identical.
-
05
Place rails, ripples, and color
Add a short deck rail, a dark bumper stripe, loose water ripples, and a few light blue pencil touches in the windows and waves.
Sketch tip: Save the darkest stripe for the bumper line. It helps the pale boat read clearly at card size.

06
Finish the keeper lines
Deepen the hull, cabin, roof, stack, windows, portholes, rail, bumper stripe, ripples, and blue accents without adding a harbor or extra boats.
Sketch tip: Stop while the graphite still feels sketchy. A few broken water marks are more useful than a fully rendered sea.
