Ok guys, what is the deal... Suppose it is blowing 20+ and you know that your sail plan is way overpowered, can you sail uni to add control?

Depends on the boat. I broke my zipper on my Nacra 20 jib and went uni in about 15-18 knots and the boat ran great until I had to tack. It took a while to get through the tacks. My roomate bought an FX-1. We took it for a sail in about 15 knots of breeze and the thing tacks like a dream. It just depends on the boat. I had to furl my jib on my 21SE on a Catalina crossing when it was blowing about 25-35 while beam reaching for 40 plus miles. I don't think we would have made it otherwise. I think uni has it's place in de-powering as long as you are willing to deal with your particular boats idiosincrosies (sp).

What you need to do is put a ketch rig on your boat, so if you need to depower, you can drop or reef the main, and sail on jib and mizzen. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

in similar wind 20+ , i have great problems to control fx1 with main sail only ( tacks verrry goood, but is too fast to make me secure)
1.problem is that when i go sailing depends on time not wether(wind) if is blowing is blowing <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
2.am to light -70kg
3.i was thinking to order custom (3/4 or 1/2 size) main sail, to depower boat

what do you think?

I lived in Maui for a few years and owned a P-19 and in the summer it blows hard every day, normally 25 plus. I bought a set of P-16 sails added a pigtail for the difference in luff length, beefed up the head, tack and clew at the locally sailmakers. The boat was totaly in control and still very fast. For a few hundred dollars I still could go sailing almost every day.

Trick in most uni's (I learned this on my H-17) is you MUST crack about 3 feet of sheet when you go head to wind or you will go into irons. Once I learned this it made sailing uni MUCH easier. Not that hard to do.

Let the mainsheet out 3 feet he's saying. Doesn't differ much sailing with a jib, you just want to let the mainsheet out a little more.
Last year just before Tradewinds Olli, Robbie, and myself sailed 3 Capricorns about 20 miles without jibs because it was cranking! I didn't even notice a difference.

My Hobie-18 and Nacra 6.0 responded well to this. The 18 was fun to sail that way - single handed in big wind - roll the jib up for upwind, roll it out for downwind. My Hobie-20 didn't seem to like it as much, and the jib is small enough on the N-20 to maybe not make that much difference.

On the N-20 a few times I have oversheeted the jib to close down the slot and the back of the main to slow the boat down. Not fast, but peaceful...

To get this the best performance (this includes tacking) you will probably needed to set your rig up as a uni.

For a NACRA 6.0 this meant raking the mast like a 5.5uni. For a Tornado, this meant a whole lot of little tweaks.

some folks seem to get mixed up with sailing a two sail boat under main only and a UNi rigged main only boat ,

The two sail reduced to main only will need drastic changes to get any balance in the boat , a designed uni rig boat will allready be balanced .

you can't really compare how to sail one to another , ones designed for the job one aint ,

I know there are a few exceptions such as dart 18 and dare I say it F16's where you can take the jib off and it will work (prob still with mast rake etc adjustments ) but they again are designed to do this

I can tack my uni rig on a sixpence (dime) without even letting the main out at all in flat water and mid strength winds , but there again all designed uni will behave different

can see any off that that twaddle will help , all two man boats i've sailed have had sufficient dewpowering controls to cope with any wind

I definitely get overpowered in big wind ...
If I don’t have crew I will furl the jib.

I find a fair amount of weather helm on my mystere 5.5 when I furl the jib. I can handle it, but I feel it.

Also tacking usually requires either very tight main sheet during the tack, or if I blow that... i have to reverse the tillers (all the way), and then push the boom away from me to complete the tack. It took me a while to get the feel for that...

If I get in shallows with no jib, and my centerboards kick up.... I have to do an immediate jibe! Or I am toast... I either have to jump off and move the boat, or pull the rudders and float backwards till I am deep enough...

I sail my 5.2 without the jib and it handles just fine. I can barely tell the difference as far as handling. However, I have very little rake in my mast.

As far as tacking a uni-rigged cat is concerned-weight aft is pretty important to getting the bows thru the wind. If you have crew you need to get them near the back of the tramp to raise the bows so they'll spin. I know I'm stating the obvious here, but it was missing from this thread.

I do that too as I sail solo and I added a spi to my 5.2. But I have two issues with this setup:

- Upwind without the jib the boat is real slow. It doesn't seem to fly as well as it does with the jib.

- Tacking in light wind is damn impossible. I can't seem to be able to get enough speed to go through the tack without stalling. And when stalled the 5.2 without a jib is very stable there... Once the wind picks up it become easier as you can build more speed and if you end up stalled it's easy to go backward.

You can't point as high with a uni. No jib to help give flow to the main. Also as I said, you have to release sheet as SOON as you go head to wind. Also in light air you have to keep movement to a minimum in light air. Any rocking will slow the boat and stall it.

Mr. Snell- I believe the statement about uni's not pointing as high, deserves more research on your part.

What Doug meant was to blow the main after you've started the tack, otherwise if it is tight through the tack it will act like a giant wind vane and you would have to back the rudders. Even if you have a jib up try this and you will go through and come out of your tacks much faster.

OK, Doug you heard the man. Get out and do some sailing! And try not to like it either. Report back with your findings.
