A tailbone rubbing problem is usually the result of a seat installed backwards. Don't laugh, it isn't that hard to do. I have known of cases of neophyte rowers putting the seats into a boat backwards because they thought the the V-notch was supposed to go under their front. Examples of reversed installation of erg seats have been reported on this forum as well. The V-notch should be to the rowers back, so that there is space under the tail bone.Alissa wrote:If it's your clothes that are chafing, then by all means make a change or use bodyglide or vaseline, but if your tailbone is rubbing on the seat, consider that you may have a posture/technique issue to address.
If that's the case, try sitting very erectly on on the forward part of the seat on your "sitz" bones. Note that your tailbone is now not touching the seat. This posture should also help make sure that your pivot is from the hip (that is, where the thighbone meets the pelvis), instead of from the low back.
Good luck!

P.S. In regard to an earlier reference to the moon, it is an astronomical fact that the Sun, Venus, Earth, Luna, Mars, Saturn, Jupiter, and even Mercury (if you are lucky) can be seen with the naked eye, but that it helps to have a mirror to see Uranus.
