Mazen, Usually Documented Vessels are the larger boats on the lake. There is a preset for being able to document, but, I don't have it right here in front of me. As far as the name on your boat, that is pretty much up to you. As long as it is not profanity. And no you do not need to document your boat. Your questions are NOT stupid. The only Stupid question, is the one that is NOT asked. On the bow, red and green, stern white light.
