Hate to say it, but looks to me like a classic case of a water logged rudder freezing which expands the water forcing the weak point (seam) to crack open. Fix is to drop the rudder, cut out one side, clean and dry it out, ensure rudder stock is sound, rebuild (foam and new glass skin), seal the stock where it enters the rudder, reinstall, check the entire steering system while you are at it – go sailing. Yes you can do it yourself question is do you want to and do you have the expertise and tools??

Today as I was observing the hull condition, I found that my rudder had the seam showing in this picture: https://drive.google.com/file/d/1D5lgN8g9YE9EAxo4RPYL9sO4vUnhYVqF/view?usp=sharing Is this something serious or I can patch it up myself? thank you in advance.
