Re: sailing with CB up?

As others have said you will be fine since the weight on that boat is in the keel. You will have a slightly more tippy motion, not from ballast but just from the short draft (think of the cb as a fan going through water side to side) and you will have a fair bit of leeway going upwind.

Avenger, I have a similar boat, 5.5m Mirage. CB (or swing keel) is very easy to operate on boats that size, but make sure the lifting cable is solid and that it is attached securely to the swing keel. I always keep the keel down unless I'm going down wind. It makes a huge difference when going upwind.

Worst case scenario you will need or want to motor back to the dock if unpwind and the CB does not drop. I sailed a mini trimaran yesterday Windrider 17. It was fun off the wind at 10 knots. At the end I had to tack back to the dock up a narrow bay. I am not sure this is the case with all multihulls without center boards but it could not point at all and it took me 45 minutes to tack less than a mile. My guess is the boat tacked through 110 degrees then slid sideways when close hauled. You can expect similar performance if your CB does not come down.

Hopefully your CB comes down or the wind stay abaft all day for you. Let us know how it goes.

Re: sailing with CB up?

thanks for the responses guys. I am hoping she drops as expected. She has surprised me so far and been a very good boat. It has been stored for nearly ten years, hence my concern of things not working properly.

the board is not weighted and pivots, not straight up and down, and she does have a very small keel (approx 12 inches), sailing sideways was my main concern with drastic heeling being second.

Re: sailing with CB up?

Yes, you should be able to sail with the center board up. In fact, this is preferred for downwind or deep reaching since having the board up will lessen your wetted surface area.

Putting the boad down will help the boat point and track better without walking sideways. It may also change the center of gravity on the boat is you've got a weighted board.

Re: sailing with CB up?

Is it a straight up and down CB or does it pivot down? I often took my Hunter 26 out without pivoting the keel down (if not racing or there were light winds). What the keel does is allow you to sail into the wind by keeping you from sliding sideways (I'm sure someone can explain it more technically, but I reckon you get the drift (pun intended)). So if you have a straight up and down CB, you'll need at least part of it down to go upwind.

Re: sailing with CB up?

Can be done, you lose a lot of up wind performance down wind with ease. Is there any type of keel on your boat or just a center board?

sailing with CB up?

well my first day on the water should be fast approaching. I'm hoping to get out this weekend for the first time. Question, just in case, is it possible to sail an O'Day 19 with the center board up? I ask because I'm not quite sure if it will come down or not. Can't check it while it's on the trailer. Once it goes in the water I can check to ensure the board drops as it's supposed to, but if it doesn't should I sail anyway?
This would be a very light wind day of 10 knots or less.
