While exiting the boat sometimes the passenger be it any mob e.g. horse/mule/donkey/villagers /zombie get hit by the my character with the item I have currently equipped e.g. sword/axe/hand/shovel/etc. This is very annoying when you try to exit the boat and if u have a good diamond sword with fire aspect and stuff enchantments, the passenger dies. Happened with me twice. Carrying stuff on the mule and it died. Also this accidental hits also happen sometimes when u try to hit someone when the character is in the boat. Same with digging while on boat. Please fix this. Thanks. 

I'm using android device and I don't think it's the human error/accidental touch that is affecting this. Its a game bug. (Minecraft PE)
