Re: Pointing Problem

.... is your knotmeter paddle wheel, etc. more or less not exactly on the boat's centerline but mounted on one side of the boat?

If so, the hydrodynamics of the paddle wheel being deeper into the water on one tack than the other and the different flow patterns across the paddlewheel due to different heeling/immersion (at the paddlewheel) may be the cause of the paddle wheel not reporting correctly on the two tacks. An offset to the side paddle wheel for a knotmeter will rarely read the same on both tacks and when the boat is heeled due to 'hydrodynamics'; only a paddle wheel mounted AT/ON the centerline will read equally when there's heeling involved. Could this be the apparent problem?

Re: Pointing Problem

As c_witch pointed out, sometimes the problem is under the boat, not above it. TropicCat has the right idea, make sure the mast is centered first. Since the placement of stanchions and other hardware may not be perfectly symmetrical, your best approach is to measure back from the bow an equal distance on both port and starboard and then mark those points. Then measure, using the main halyard to each point. If they are not equal distance to the mast top, then the mast is not centered.

If it turns out that the mast is centered, and you can dive on the boat, you may be able to see something obvious. Growth on one side of the rudder or keel can have a big effect on pointing ability. If this is not something new to the boat, it could be the rudder and keel are not on straight as well. In any case, diving on the boat would likely only provide an opportunity to confirm the problem, not fix it. If the problem is under the boat, you will need to get it out of the water to correct the issue.

Re: Pointing Problem

How about current? That will certainly affect your performance. My boat doesn't point worth a hoot. Lot's of leeway. But, I've sailed 5 degrees off a whisper of a wind. Really weird, but true. Slack tide so no current. Wife was dying to start the motor but I wouldn't. It's a guy thing.
