Re: How high can you point?

Lets stick to talking about the angle we tack through, as that is a much better measure of how a boat points.
Some of the things that effect pointing are:
bottom condition and foils
sail condition and cut
GPS angle is what counts, with adjustment for current. Wind angle is interesting but slightly off the point.
Eventually, VMG is mostly what counts, though pure pointing can count if space is limited. This will require a little trig, unless you have some cool electronics, but you learned it in high school. Sometimes 100 degrees is faster than 80 degrees, sometimes not; it can depend on waves etc.
