Will most boats tack with just a jib in 30 knts or more? With my mast head sloop I have found I really need a deeply reefed main in strong winds to be able to tack and to make any upwind progress, and it balances the helm much better. Going down wind the jib alone seems to work ok.

I was thinking the same thing--- I guess maybe when your not in small water bodies you can use the job going upwind because you can time the wave periods to your movements.
However, in say, the St. Johns river, the waves build up fast and rough after 20 knots-- the waves movements are chaotic at best. So under these conditions I don't see it working (I tried VERY hard yesterday in fact!)
I will use the main in conjunction next time, as well as charting a better course in the first place!

I have tried to time the swells and I still cannot tack. With stong winds there is not only the waves pushing you back but also the wind load on the boat and rig which can be significant. One thing I have found is reefing (main and jib) makes a huge difference in boat comfort and handling.
In most cases when I sail I probably am over reefed, but this is much better than too much sail or having to reef when short handed (over reefed just means I am going a little slower- no big deal). I have also had a situation I lost total control of the helm until I reefed the jib. You sound like a fast learner- good luck.

From my experience, I've beat upwind in numerous different boats under jib alone, from a Rhodes 19 to a Southwester 42, and have never found progress upwind or tacking not feasible. A main certainly simplifies handling, but not too many boats can carry a small jib and a double reef main in 30 knots (my CS 36T had a 85% which I would use alone in that wind speed). Like that the maneuvers take more attention and thought than when you have the main in the sail plan.

Certified...in several regards...

Re: Over Powered in 30 knots?

Like the other posters said, you need your main. I hope it's blowing like that tomorrow, because I'm going day sailing out of St Aug in the afternoon...

It looks to me the boat in the middle would be sliding sideways and have no steerage- looks nearly totally out of control.

Re: Over Powered in 30 knots?

Ok, I won't beat a dead horse here, but yep, SOME boats (mine included) require a bit of main as well. I agree though in 30 knot winds, I'd be done!

However, some other observations (and not condemning here) but yeah, probably not a good idea to be out in those conditions with a known dodgy motor.

However, take a look at the "throttle return spring" on that motor... we spent tons on a volvo penta for the same problem, with similar governor work, and found a broken return spring to be the problem.

Finally... once fixed, MOTOR SAIL! Every last bit of forward momentum my friend....

if you plan on sailing those kinds of conditions in any regularity, might be a good idea to get a set of stormsails (I know easy to say, big bucks, yep I get it).

I second the 270s to change point of sail. I've done this kind of "chicken jibe" to move from port to starboard tacks.

Re: Over Powered in 30 knots?

I''m not sure if this has been mentioned but if you must sail upwind under jib alone you can usually tack if you foot off just a shy higher than a beam reach, then as you turn the boat into the wind let the jib go and your momentum should carry you through the tack. By pulling the jib tight as you get closer to the wind you are actually worsening your balance by causing more pressure on the jib making it harder to complete the tack.

Re: Over Powered in 30 knots?

You could also do what the old square riggers used to do. They could not go to weather at all, so if they needed to change heading through the eye of the wind, instead of tacking (which we do but they couldn't) they would wear ship. To wear ship is to gybe around (270 deg or so) until you're on the other tack. It's like the opposite of a chicken jybe.

You can make up for the frustrating fact that your boat is being piggish and won't tack through the wind by impressing your friends with your knowledge of obsolete nautical terms.

"All hands prepare to wear ship!"
