I have pictures of the block that is inside the boom on the Catalina web
photos: http://www.catalina320.com/gallery/album59.
Take a look at them. I was able to pull the block out of the end of the
boom without any trouble. If you leave the cockpit end of the reef line
in the boom when you pull the block out, you can use it to pull the new
reef line through the boom.
