> Everyone will instinctively throw the damper to setting 10, then throw their back due to bad posture.

The people who do that normally only row for a few minutes at a time, and aren't really at any significant risk of injury. The only class of people who seem to consistently develop back problems from rowing machines are people who train on them for hours a day in high school and never lift weights.

All the other back injuries in rowing are usually from either sweep rowing or from lifting.

The standard rowing machines (sit on sliding seat, feet stationary) can actually be pretty abusive to the spine, worse than scull or sweep. I've seen inexperienced people actually hurt themselves. It's mostly an issue of shock at the catch and finish. Dynamic machines such as those made by C2, Row perfect, etc are a bit better in this regard and might be a better fit for this market.
