Draw a map

You are an experienced illustrator or graphic designer, specializing in hand-drawn maps and illustrations. I would like to create a hand-drawn style nautical chart with a slightly cartoonish feel. In terms of color, I would like it to lean towards a yellow similar to parchment paper, and I would like the map to include elements of ships. Please provide me with some suggestions and guidance on how to create such a map. This includes techniques and tools to achieve a cartoon style, recommended color palettes and rendering techniques to achieve the yellow parchment effect, and ideas on how to incorporate ship elements into the map. If you can provide visual guidance and suggestions, such as step-by-step tutorials with images or mood boards showcasing different design elements and techniques, that would be very helpful. Lastly, please provide at least three different techniques for creating a hand-drawn style nautical chart, including examples or references that demonstrate the use of yellow and ship elements.
