NW location boaters

Hi,

Just wondering if there is anyone in or around karratha on here and has a good knowledge of boats (esp DIY) that may be able to look at my cabin.

i have an area in my cabin that was used as a toilet (its in the middle of the cabin!) , however we dont have a toilet, and wont be getting one, but would like to look at moving the fibreglass recess area the toilet sat in to allow for the floor to be able to walk on. I dont want to go in gung-ho with a saw until i know that by removing the walls of this i am not causing any structural damage to the actual boat.
