Dr. Valery Kleshnev of BioRow Ltd. – a rowing biomechanics consulting company – recently performed a drag factor test of four singles, one of which was the WinTech Medalist.
Per the April 2015 newsletter:
“Four singles of different brands were recently tested in an indoor tank (600m long, 16m wide, 7m depth, constant temperature +16 C) at Krylov State Research Centre in Saint Petersburg, Russia.
The boats were:
- Empacher (X10 A115, 2013, 85-100kg)
- Filippi (F14, 2011, 80-95kg)
- Wintech (Medalist, 2014, 75-85kg)
- Nowing (local boat builder, 2014, 75-85kg)
The purposes of the test were to define the drag factors of each boat using two methods: rowing and towing, and then to find their correlation.”
The findings favored the Medalist, citing:
“Summary of the results of rowing and towing measurements: WinTech boat had the lowest average drag factor, Empacher 0.78% higher, Nowing 2.35% higher, and Filippi 2.95% higher. At the propulsive power 400W (rowing power 508W and time at 2km race about 6:35), above differences in the drag factor would give the advantage to WinTech of 1.02seconds over Empacher, 3.06s over Nowing, and 3.84s over Filippi.“
