Duckpin bowling Duckpin bowling Duckpin bowling is a variation of 10-pin bowling. The balls used in duckpin bowling are in (12 cm) to 5 in (12.7 cm) in diameter (which is slightly larger than a softball), weigh 3 lb 6 oz (1.5 kg) to 3 lb 12 oz (1.7 kg) each, and lack finger holes. They are thus significantly smaller than those used in ten-pin bowling but are slightly larger and heavier than those used in candlepin bowling. The pins, while arranged in a triangular fashion identical to that used in ten-pin bowling, are shorter, smaller, and lighter than their ten-pin equivalents,
Ten-pin bowling influence lane conditions and scoring. Establishing a Bowling Ball Specifications Task Force—comprising research engineers and volunteers from ball manufacturing companies—the USBC sought to better understand the motion of bowling balls using scientific research and data analysis. Test equipment included, but was not limited to, a robotic ball-thrower, a Computer Aided Tracking System ("Super C.A.T.S."), 59 reactive resin and particle bowling balls from various manufacturers, and eight lanes in a climate-controlled facility. The driving force behind the study was summed up by USBC Technical Director Neil Stremmel: "USBC is concerned that technology has overtaken player skill [as the primary factor] in
