Alternatively, two long feathers can be spiraled around the end of the arrow shaft. In either case, the excessive fletching serves to generate more drag and slow the arrow down rapidly after a short distance of about 30 m (98 ft). Recreational flu-flus usually have rubber points to add weight and keep the flight slower.

The Karatsuba algorithm is a fast multiplication algorithm. It was discovered by Anatoly Karatsuba in 1960 and published in 1962. [ 1 ] [ 2 ] [ 3 ] It is a divide-and-conquer algorithm that reduces the multiplication of two n -digit numbers to three multiplications of n /2-digit numbers and, by repeating this reduction, to at most n log 2 3 ...
Bowfishing arrows generally lack fletching, as it can cause the arrow to flare to one side or another underwater and they are not required at the relatively short ranges associated with bowfishing. Lighted nocks, and other custom features for arrows associated with night bowfishing are commonly available.
