Paul,
Thanks for your welcome and info. By the absence of other replies to my question, there doesn't seem to be anyone else who has had experience of drying out over an extended period. Perhaps I am a bit impatient! However, I have been told by our fairways committee that several boats (albeit a bit larger than the 235) use a bucket on a short rope (2 metres approx) to steady the motion when moored. So perhaps this type of approach may be the way to go. Nevertheless, it would be reassuring to hear from someone with experience of 235.
Regards
