Sailing in denial. I love it!

When I sail in denial mode, my boat tacks through 70 degrees.

But how come I can never call a lay line?

The fluxgate on the AP says about 100 deg between tacks after adjustments. Don't really care though as long as the boat is groovin along kinda where I want to go. I just use the wind instrument as a general guide, as I sail to the tell tails on the main and Gen. Not a racer, although the boat is a 1975 IOR design.

So add some more for leeway, and you will get the angles you see on your track in your chart plotter, which is your real tacking angle. 100 to 105 degrees is pretty good for a cruising boat. Anything under 100 is starting to get really good, in my book.
Someday I'll have a chartplotter
Just have wind, depth, speed, and AP instruments.

This discussion is bound for trouble. Why do you want to sail to weather in the first place?

is ok for ye to sail circles around me----i will laugh and have fun!!!!
If you're in the Gulf try just a few boat lengths from a rig or a weedline. Use fresh bait they can be picky eaters. A technique I have seen used. Cut up a few halves of a bait fish, bang them against the side of the boat, then throw them in the water, then repeat with a hook in one, (duplicates a shrimper culling). Good luck, they are great BBQ'ed

Yeah, the guy that taught me how to sail many mny years ago had two sayings:

"You can't make any money pinching." and "Gentleman never go to windward."

Mark,

Folks who spout that old saying (gentlemen...) have their own way of getting to upwind destinations: it's usually called motoring.

Many of these folks call themselves "sailors".

Cheers,

Jim (who has found lots of desirable destinations that were to windward)

The downwind anchorages are all full at this point.

Re: How High Can You Sail ?

In my experience the biggest difference between a how a racer (or ex-racer) sails and a cruiser sails is the former truly understands apparent wind (both angle and velocity).

Re: How High Can You Sail ?

I never saw much use in knowing how well my boat can point into the apparent wind. The only thing I've found important is what angle she'll move in relationship to the true wind as measured over the ground. On my boat this is about 50 degrees without loss of speed over the ground (GPS measured tack angles of 100 degrees). While the bow is pointed much closer to the true wind, I loose a lot to leeway at these angles. I can get about 10 degrees closer but at a significant speed penalty(droppng from 7-8 knots to 1-2). All of this assumes of course that my sails are well trimmed. If I'm at all sloppy about my sail trim I will loose another 5-10 degrees. I sail a condomaran and would expect those boats to point much better. A stretched out main will not help as would too much drive from the jib. The jib tends to push the bow off and I know if I have my jib trimmed in too much I loose a few degrees as the main can't push the bow around. If you have a combination of a stretched out main and too much drive from the jib it could easily take 5-10 degrees off of your pointing ability. Some boats point much better with no jib.

Since these are club boats, are other people doing better at pointing on these same boats or are you afraid to ask? The answer will tell you if it's you or the boats.

Good point. However........the same good boat preparation and sailing technique that gets one upwind fast with small tacking angles applies to getting downwind fast. So you might better say "who wants to go fast in the first place?"

For me it not so much the going fast that matters. It's making headway without having to give up sailing and motor. Or stay in port, frustrated.

A well-sailed boat can make small angles gybing downwind to make good progress in light winds. The small angles keep the apparent wind at nice efficient angles without having to sail far off course. Good VMG without motoring. Same thing as windward work.

I sail my boat really high all the time if I don't my neck hurts from looking up at the winddex to see how high I'm sailing
