Reinforce
Not sure why someone would want to do these things. I would say that the rigging is fairly solid. With 6 shrouds and two stays mine withstood wind and waves last summer that two other different boats were demasted.I believe that on paper the boat is supposed to be good up to 6ft waves based upon the waterline length. (I wouldn't want to test this) Problem in heavy seas is that the variables are more interesting. Down below, I believe that the fglass in the sink area actually helps to reinforce the port bulkhead. The only reinforcement that I've seen done by racers is to attach the lower shroud fittings down at an angle to the bulkheads with turnbuckles. This takes the strain off the deck at the base of the lower shrouds. If the Deck's soft, it could be that the wood core is rotted from leaks. I replaced my bulkheads because some leaks in the shroud straps cause the bottom of the bulkheads to rot. I also made the attachment points of the bulkheads to the Fglass stronger. As far as using the boat for Bluewater, I would check with people like Philip and Sharon Merlier of Fla. and Chip Ford of Maine about the boat's capabilities.See the CD forum under Cruising areas. I know that Philip and Sharon have sailed to the Bahamas and around the Fla. Keys. As for a new 22. I don't think that the rigging and the glass is built to stronger specs on the newer ones. Just newer. Of course you can buy a new one that's laid out in the interior like a day sailer instead of a pop-top camper.If you are dedicated to this idea though, there is some good reading at the CD forum's "Cruising Areas" section (Specifically "Transatlantic crossing" that would give you some ideas on seaworthiness and correct mods. including using a solid keel and a keel stepped mast."The truth is that even though I love the Catalina 22, and the boat is brilliant at what it was designed to do, you’d be better off modifying another boat for the same purpose. Look at the “Falmouth Cutter 22'” for a clue of what you may have to do, The “FLICKA” and the “Pacific Seacraft - Dana 24” are also good choices. By the time you make all of these upgrades you would have a one of a kind boat that is as expensive as one of these other small blue water boats."
