This is my first post. I am a very new sailor with a Hunter 14' dinghy. I have 2 small questions. (since i am so new my descriptions of things will be simple and probably inaccurate). At the end of last season, the stretchy line that seems to hold down the center board broke. I looked in the manual for how to replace it and the manual showed almost nothing. What do I purchase and where can I purchase a new line for this centerboard? The second question is about the hull. Because it was in the water (fresh water) all summer, when I took the boat out at the end of the season, it was filthy. Is there some special thing I need to do or some special process I need to go through in order to clean it? I would also appreciate suggestions about any cleaner(s) that I need to avoid. Thanks for your help. Hopefully my sophistication about boat matters will improve over time.
