Question:Recently doubts were raised about the assessment of the length of some holes on our course. Could you please tell us the correct method for determining this measurement? Perhaps you could also give us your advice on how best to cut the hole for the pin on golf greens without "crowning" the hole. Is a board necessary?
Answer/Response:The official ruling on measuring length of holes is to be found in a booklet regarding Course Measurement published by the Council of National Golf Unions and we quite:- "Measurement shall be by plan or projection along the horizontal plane from a point (which shall be marked permanently for future reference) 6 feet * in front of the rear extremity of the medal teeing ground to the centre of the green of each hole (to the centre of the rear section of a two level green). In the case of a dog-leg hole, measurement shall be along the centre line of the fairway to the axis and then to the centre of the green. Measurement shall be carried out by a qualified surveyor, or someone competent and experienced in the handling of surveying instruments, who shall grant a certificate showing details of the length of each hole and the total playing length of the course. Subsequent alterations to the length of the course will require a certificate only for the altered hole or holes which shall be measured in the manner prescribed above." As regards hole-cutting, many experienced Greenkeepers pride themselves on being able to cut a good hole without a board. Nevertheless some Greenkeepers cut the hole through a board as a safeguard against crowning and in general this proves to be successful. With or without a board, the hole-cutter must be sharp so that a clean cut is made. IT must also function properly so that the turf plug and soil is withdrawn efficiently to a depth which allows the hole-tin to slide readily to the necessary depth below the surface. If the hole is cut too shallow the hole-tin has to be "rammed" in, this in itself might crown the hole. We would also add that if a hole is sited on an area of very fibrous turf then constant foot traffic around the hole (to retrieve the ball) will depress the fibre except for the last 25-50 mm (1-2 in.) or so around the top - this would effectively make a hole crowned. Under these conditions a hole apparently in good order one day may, following heavy play, be crowned by the next day. This would relate to the fibrous state of the turf and not to faulty hole cutting. In this situation the long term answer is fibre reduction by means of scarification, aeration, etc.
