Teeing Ground

no, to be absolutely correct it needs to be less than 0.84".... :thup:

Oooh - yes - I guessed that response :) And so...we have the vertical plane defining the forward limit of the tee ground to be the tangent plane to the ball. Are they in fact touching? Mathematically yes they are. Does that mean that that ball is within the tee ground? Probably not as a no point of a sphere can intersect a tangent plane to that sphere. So yes I concur - my vertical axis of my vertical tee must has to be less than 0.84" forward of the vertical plane defining the front of the teeing ground.

This begs a related question. Is a ball in GUR if it is sitting on the white line defining the GUR? If YES then at what point is the ball NOT in the GUR? When the vertical tangent plane to the ball at the point of the ball nearest the line defining the GUR does not touch the line?

Also - and a little at a tangent (sorry). We have many bunkers undergoing work at the moment. They have white GUR lines and have been GUR. What does it take for these bunkers to no longer be GUR - given that the white GUR lines and any applied GUR lettering will not disappear overnight,
 

That is just nonsense. There is a sound and practical purpose to using the correct terminology when referring to the Rules.It avoids anyone reading this form getting the wrong idea. Many might read "teeing area" to mean the whole of the ground prepared for the purpose and if you are going to instruct them on the penalty for teeing off in the wrong place, you must refer to playing from outside the teeing ground because that is precisely described in the Definitions. Teeing area is not defined and in rules terms has no significance.

1. yes; the line is in the GUR
2. when no part of it touches the line (the same answer to the question of when a ball is 'on the green')
3. no; when the ball physically touches the line or is below the line (effectively underground) when the plane becomes a factor. the margin doesn't extend upwards only downwards.

4. when so defined by the committee

Anyway - I've never heard anyone ever call it the 'Teeing Area' - probably because that's not what it's called ;)

As I thought - other perhaps than 3) as this is then different from what you've described for ball position relative to limit of teeing ground where the ball can overhang the defining line and be 'legit' without actually physically touching that line. But I guess the key thing is that ball position relative to GUR boundary relates to a physical relief/aspect of playing the game with the ball in play - whereas definition of teeing ground and position of ball relative to it is an aspect of the rules rather than anything to do with ball in play.

Decision 26/1 applying to Water Hazards (and also the definition of OOB) indicates that if any part of the ball 'breaks' the vertical plane of the margin, then ball is within GUR (or WH or in-bounds).

I've seen the GUR 'cancelled' or crossed out by a great line through the wording and lines - and notices explaining how to interpret the markings posted around the clubhouse.

To be absolutely correct, we need to recognise that the diameter of the ball isn't fixed, but must not be less than 1.68", so the tee peg could be further ahead of the tee markers ...

Has anyone ever seen a ball bigger than 1.68"?

I've heard the terms 'teeing ground', 'teeing area', 'tee box' and 'teeing box' all being used to describe the same thing! :)

Did you actually read and digest what I was saying? In short, the point is that all the terms you have heard describe, but only one defines. If you are going to pronounce on the Rules, use the one that defines.

I'm only trying to help, and you are being ridiculously pendantic! I am sure that everyone would understand what I wrote, and I did refer to and even copy out the relevant rule further back in this thread. :rolleyes:

Which 'same thing'?

The teeing ground as defined or the area (often raised) surrounding the teeing ground?

I really, really hoped you weren't going to resort to the "everyone understood what I meant" cop-out.

Don't believe Wikipedia - it's wrong as well - as is GMac on one of his vids. May casually to Tee Box but in the rules it is Tee Ground.

My understanding has always been that the Tee Box is the entire prepared area (which is often compulsory GUR during winter at many clubs - certainly is at mine), whereas the Teeing Ground is that small area within it defined by the markers.

Showing my age here, but the "Tee Box" was the metal or wooden box situated on every tee containing sand, which golfers used to tee their ball up before the invention of wooden & plastic tees. We still have them on our course as rubbish containers now & not so long ago they were painted with the hole number, yardage , par & stroke index.

Many people refer to "Tee Box" without knowing this.
 
In addition many people refer to the teeing ground as 'the tee'. As in "I'll go back and play another from the tee".
