Hello Catalina36.org rg community.
I'm the new owner of hull#2224 (2005 C36MkII).  I have found the information on this website extremely valuable as i've gone through the boat doing preventative maintenance.  Thank you fo those who have posted.
Projects completed so far:  standing rigging replacement, mast rewiring incl LED lights, hose replacement, PSS bellows replacement, Raymarine radar replacement, Edson steering system maintenance. Also annual engine maintenance and bottom and hull work. Still to do this season: upgrade old Raymarine C80 display to Axiom+.  
Happy sailing!
