Kant's Nonconsequentialism

I am not able to wrap my head around this concept. If I were in a life boat that only had capacity for 10 normal sized people but there were 11 on board, 10 normal sized people (including myself) and a 400 pound man. The boat is sinking and if someone is not pushed out we would all more than likely die. Based on nonconsequentialist's viewpoint should I push the 400 pound man over board or let him stay and hope that a miracle happens?

I just cannot get past the consequentialist viewpoint on this.
Please help!!
