My wife & I recently learned how to sail and bought a nice O'Day 20 to sail in Narragansett Bay, RI. My wife is convinced we're going to capsize whenever the boat heels even a little, say like about not much over 5 degrees. Having a centerboard, I'm pretty sure it can, technically, capsize, but with the partial keel, I think it would take quite a bit of wind for that to happen.
Any O'Day 20 sailors, maybe even one who has capsized, want to give me some info on this?
I have an 86 O'Day 222 that I bought new at the boat show many years ago so I can't really speak very much on the O'Day 20 as I've never sailed one. Two of my friends in the club have owned the O'Day 20 and they seemed pretty happy with them.
The 222s have a keel/centerboard with an 800 lbs keel but they can have their scary moments in big wind gusts. I've found this out many times while sailing the Taunton River which can kick up just as much as the bays.
All mono hull sailboats heel and there will be times when the wind is really light and you'll find that sitting on the low side to make her heel will actually help her speed as she's ghosting along. Then there will be times when the wind is a little stronger than usual and you're going to need to keep the Main sheet in your hand just in case you need to let it off real quick to spill the wind. It this situation I think that most of the time you will be able to accomplish this same task by using the tiller to head her up a little bit and I strongly advise that you practice this constantly. The important thing in sailing is to keep the boat's "way on" and don't let her stall. Forward movement provides rudder control. This is a good thing to keep in mind as you are learning about your boat. This is where a good Windex wind indicator comes in handy and I'll talk to you more on that later.
I think that what you need to do is get used to your boat and experiment with different sail configurations just to find out what works and what doesn't work.
My boat can maneuver and sail very well with just the Mainsail. I'm not sure if that is the case for all sloops of this size. Some may stall when coming about and fail to tack without the Jib or Genoa sail working.
When the winds really kick up I roll up my Genoa and just use the Mainsail. If the winds are to over bearing for the full Mainsail, I'll reef it.
I think that it's important that you rig up a boom vang and use it when the wind kicks up. If you don't have one it would behoove you to get one and install it.
Probably one of the most important things you need to have is a good wind indicator and I'm not talking about yarns attached to the stays.
Davis makes a great Windex wind indicator that has a "V" shaped vane attached to it. I bought one years ago and attached it to a 12" extension bracket and mounted it at the top of my mast on the Port side.
These things are great especially when sailing downwind which can be scary if the wind gets behind the wrong side of the sail and causes an accidental jibe. The Windex can alert you before hand if you are keeping an eye on the pointer in relation to the "V" shaped vanes.
So in the final analysis, you need to get used to your boat and learn all of her little idiosyncrasies. If the wind is really piping up with large wind gusts that come up all of a sudden, don't go out sailing in it, or just find a well protected cove to hang out on the hook for a while.
Trust me on that last one. I got into sailing late in life and never took lessons. I went to the city library and drew out books on sailing and learned by going out and practicing what I read. To this day, I won't even go out there if the wind is really more that I want to handle. I'm not too fond of having to fight the wind and waves while I'm getting hit in the face with spray and getting my butt soaked in the process.
My dog Penelope isn't too fond of rough weather either. She hasn't mastered the MOB maneuver technique and if I go over the side, I'm on my own and so is she.
With that said though, we've sailed our O'Day 222 all over Mount Hope and Narragansett Bay, Block Island, Cuttyhunk, the Elizabeths, and Martha's Vineyard. We've always picked the days when we sailed to these places because these are small boats and bays can kick up.
Good luck with your O'Day 20! Hey maybe I'll see you out there some day and give you a wave. Narragansett Bay is my favorite sailing area especially the Northern end of Prudence.
