Two Steel Boules and a Gap Worth Measuring

Pétanque 🎮 Play: Too Close to Call

Someone crouching over a gap persuaded me to stop beside the pétanque game. From the path, the two steel boules looked equally close to the wooden jack. A measuring tool settled the question. Then someone lent me boules, my first throw rolled thoroughly past everything, and hobby #248 acquired two separate problems: getting close, and establishing what close meant. I spent an unreasonable portion of my first afternoon on the second.

Leave the evidence where it landed

Measuring matters before the scoring discussion. Normally, the team without the closest boule plays next. A doubtful gap can determine whose turn it is while both teams still have throws available.

Under the FIPJP’s rules on measuring points, the player who last threw, or a teammate, takes the measurement; opponents may check afterwards. Appropriate instruments are required. Measuring with your feet is expressly forbidden, closing off an entire department of confident estimation.

There is also a consequence for clumsiness: disturb the jack or a contested boule while measuring, and your team loses the point.

That made me withdraw my helpful hand.

The unfinished bookmark from bobbin lace making remains beside its practice strip because I undid crossings before identifying the last correct one. I recognized the temptation here: reach in, improve access, then discover I had removed the information needed to answer the question.

Carry the gap across

For a close comparison, callipers provide a useful approach. Their opening preserves a distance while you move between candidates.

This sketch shows the principle, with the objects separated along one line:

boule A       gap A       jack       gap B       boule B
  ( O )  <------------>   (o)   <------------>  ( O )

Compare the nearest surfaces. A measurement to the jack’s centre answers a different question. Likewise, putting the tips somewhere convenient on the curved objects can produce an opening that spans something other than their closest separation.

Mike Pegg’s guide to umpiring describes a careful calliper procedure:

1. Set the opening smaller than the gap before inserting the tool.
2. Brace your hands on the terrain, or support an arm against your leg.
3. Approach the heavier boule first. Hold the callipers at the angle needed to reach the nearest points.
4. Withdraw the tool before adjusting it. Open it gradually, then try again, seeking minimal contact.
5. Preserve that setting and compare the other boule with the jack.

Adjustment happens away from the objects. Trying to open the tips inside a tight gap recruits the jack as a mechanical stop. It has not agreed to that employment.

A preserved opening gives a direct comparison. If it matches the first gap but is too wide for the second, the second boule is closer. If there is spare room in the second gap, the first is closer. No decimal reading is necessary.

When the answer changes with your hands

The awkward case is a comparison that reverses when repeated.

My instinct was to keep trying until it produced the answer I expected. A better practice exercise is to withdraw completely and rebuild the measurement, checking what changed: hand support, approach angle, tip placement, or the opening itself.

Repeating an unstable placement more often does not make its verdict more convincing. If the apparent difference disappears whenever the tool is repositioned, I cannot yet distinguish the gaps reliably with that setup.

Nor should another boule obstructing access become an invitation to tidy. Articles 25–28 of the official rules allow intervening boules and obstacles to be temporarily removed for measuring after their positions are marked, then restored. Contested objects need to remain undisturbed. An umpire can be consulted when the comparison remains disputed.

That distinction gives me a useful stopping point. I can practise handling the instrument without appointing myself the final authority on a difference I cannot reproduce.

By the end of the afternoon, I could explain the measuring procedure more convincingly than I could deliver a boule. My next throw finished well beyond the jack again. Nobody reached for the callipers. That particular comparison remained comfortably within unaided human capability.
