Since we live on the coast we need to have ways of drawing boats. Drawing boats can be tricky because they involve ‘compound curves’. This means that traditional linear perspective needs a little help from some other concepts. Here is the way I approach it: I use the ‘infinity sign’ method if the boats are close to eye-level, the ‘leaf’ method if the viewer is above the boats, and the ‘beak’method if the boat is coming directly at the viewer, such as on a beach tide-line.
This is a video of a 1-point perspective urban scene that I hope you will try.
Also, look at an earlier perspective with a similar theme. If the link below doesn’t work directly , copy-paste into the search box at upper right of webpage.
People have asked if reflections should be longer, shorter, or the same as the actual object. The annoying answer is “It depends.” I made a little sailboat (about 3 inches high) by carving a white vinyl eraser and making a sail by cutting a credit card, painting it white and drawing a curve with a sharpie. I placed the model on a hand mirror and took some shots. I have done the same thing with toys of animals, people, etc. I like to make little quick model set-ups to study such problems, including light, shadow, etc. As you can see, the height of the reflection depends on the angle of the object vs. the mirror surface. The same thing applies to mountains or trees along a lake edge.
