Reef early & often
Sorta the Catalina owners motto! To answer your question: yes, you can dump a C22 since they're not very heavy especially compared to 30 knt winds. Hopefully some experienced C22 owners will be able to give you more specific advice but I would suggest being very aware of what kind of winds are forecast for when you go out, that way you can be prepared with proper sails, etc. If it starts picking up, reef your main early. This saves you from doing it when you're getting the crap beat out of you later! Besides, you'll have better speed if you keep the boat under control. If you still have too much sail up, reduce the size of your jib. If that's too much, take the jib down entirely. I'm assuming you only have one reef point in your main - if you have two, reef a second time - if not take it down completely & head for home! Although C22s aren't easy to knock down, it can happen and when it does it can be catastrophic. Usually folks go sailing with the hatchboards open so they can get below quickly. I would suggest replacing the hatchboards before going out. That way if you do, by some freak of nature, get knocked down, your boat won't fill with water and might prevent it sinking. Make sure the hatch is closed as well or the boards might just float away.Like I said, this isn't a common occurence but it can happen in heavy winds, so better to be prepared than not. Good luck!LaDonna
