The stake format was often used in early American races. Competitors line up at the start, race to a stake, moored boat, or buoy some distance away, and return. The 180° turn requires mastery of steering. These races are popular with spectators because one may watch both the start and finish. Usually only two boats would race at once to avoid collision. The Green Mountain Head Regatta continues to use the stake format but it is run as a head race with an interval start. A similar type of racing is found in UK and Irish coastal rowing, where a number of boats race out to a given point from the coast and then return fighting rough water all the way. In Irish coastal rowing the boats are in individual lanes with the races consisting of up to 3 turns to make the race distance 2.3 km.
However, I own an air rower and have zero worries about maxing out it’s ability. I can completely exhaust myself on any type of workout. Air and water rowers are the chosen resistance type by Olympic athletes and any athlete looking to train their full-body cardio. I don’t think they would choose this resistance type if they felt they could max it out.
There are 4 main rowing machine types that are classed according to its utilized resistance mechanism. Having an exercise workout needs to have resistance against the movement in order to provide to the muscles and the cardiovascular system a good change. This can be provided by the rowing machine whenever you pull its handle and then slide back to the seat. Having low resistance works on the cardiovascular system can make you row fast easily. Having high resistance means that it provides you with the anaerobic session, working with the muscles harder, also having a slow stroke rate because of the harder pull.
