As this is quite an old thread with a vague title, and recent posts have caused some frustration to some members, I suggest your post might be better placed in a new thread. The original thread was about purchasing
a Gemini--you could start a new thread now that you have purchased your Gemini.
I think a new thread could possibly start quite a lot of sharing. Maybe the thread could be titled something like Upgrading/refitting a Gemini 105
and be a thread where members might benefit from reading about your "experience and mistakes" and/or "feedback" could be offered to you from Gemini owners or other forum members
Others might take a look simply because it is a new thread. You could simply copy your post from here and create the new thread or I believe you could ask a moderator to move it to a new thread.
I'll be interested to see/read what you do to your boat
. Good luck.
