Help with Broken Upright Please

We installed a new type of upright (post) on one of the floats, these are aluminum rather than wood.  One of them has been broken off and we would like to discuss this with whomever was involved.  We are very interested in any feedback on how this was broken, as we may need to reevaluate this new type of upright.  Our intention is not disciplinary action but to get feedback; any help would be much appreciated by the Board and helpful to the club.
