The saying many hands make light work is especially true when it comes to the coaching and the organisation of a rowing club. If one person were to take everything on they would soon find that they had bitten off more than they could chew especially if they are looking after a large amount of athletes.Its like trying to win an eights race with only your self in the eight, by your self you'll accomplish nothing but with seven others, working towards a common goal, anything can be achieved.
Giving people responsibility gets them involved and in most cases committed to your cause. So much work needs to be done to run a club, fundraising, people management, coaching, equipment maintenance, tracking of finances and much more, having dedicated people for each job ensures enough time is spent on each one and that the club wont suffer due to lacking commitment or time in a certain area.
The people who under take these rolls can be current members, ex members, parents, coaches, alumni, etc. However that only covers one side. If a club is to be successful, it must, in most cases have members of different ability. This ensures as some members leave. There are new members coming up to fill the gaps. This must be done not only for rowers but also for the coaching, and administrative positions throughout the club so that all of a sudden the club is left struggling due to a few key members leaving.
