No problem about using the picture. One of the reasons that I started the blog was to try and get in contact with other Cascade 36 owners so we can share experiences.
Yes I am getting lots of enjoyment out of Nolwandle, just wish I had more time to use her.
I have not found any delamination in the deck, but there place where when I walk there is some creaking, but nothing that I have thought to be serious.
Regarding your rudder - I hope you have seen the picture of where my rudder was leaking water when I took it out? This concerned me alot, but a friend who is a surveyor came to have a look and assured me that there was probably no problem.
I had been intending to do something about a slight looseness of my rudder, which at high speed results in a vibration. I originally thought there were actually rudder bearings, but then after corresponding with other owners I realised that there is actually no bearing. Others have put a "nylon sock" over the stock. Have a look at http://edcleary.com/kaiulani/projects.html
I think when I next take Nolwandle out of the water I will probably do the same.
If you get a chance can you send some photos of your boat and the work that you have done on her.
