How about an experiment to see if it does anything... Someone tested adding a hook on a boat a few years ago. They taped or glued something on. You may be able to find the thread.
You could tape or glue something like a foot or so (maybe two feet) in front of the hook, getting as "tall" as the hook at the back of the boat. This would negate the hook effect some and just simulate a slightly deeper hull. You could use the result to see if grinding is a good idea?
Or this could be a crazy stupid idea.
