Just a note about my wood iSonic 111 (2008 model). I got mine in Nov. of 2007 and after 4.5 years and 130 days of sailing on it, it still looks almost new. No dings or repairs and the wood still looks good (no superficial cracks with wood discoloring).
I record all of my outings with a GPS and put the info on a spread sheet (board; sail; wind speeds; distance sailed; average speed; top speed; time on the water; location; date).
