Twas not me who downvoted you. I did not even know before today that HN won't let me downvote any comment on my own submission (unless you need more points for that too). Only the upvote arrows appear for me here. You may not be grumpy, but having many short questions with a sarcastic tone ("cute") or negative slant comes across very aggressively. I realize the website may not provide all the answers to someone who has no knowledge of the domain (sailing), but I think it provided enough visuals and information for someone approaching it with an inquisitive mind.
