!Website Retirement!

I make no income from this site, in fact it costs me a little to run it! I originally created this website when I built my first wooden boat, the website code is now 13 years old, and will require a complete rewrite to continue funtioning properly. With only 25 average daily page views, I feel that the website would not really be missed. If you wish to see this website continue please send an email to me at  jim.kubik@jkwoodstudio.com.
