We no longer have our 1984 Catalina 36 located in the upper Chesapeake Bay but we are selling some items locally in good to new condition.  Our Mark I was produced until the early 90's so I think any 1984-1994 Catalina 36 would be
able to use the following. Email for more information if interested.  
 

Fully rigged spinnaker with sock and sheets (red, white, blue). Asymmetric - 76-BSZZ-880: foot = 26”, length ~ 44’.  $1600 -Only used 1 time.
