Grounding to hull

Using the metal conduit as the ground is acceptable but I have seen cases where they used the conduit in place of the common wire in house wiring. It gets your attention. I like a dedicated wire for everything. It saves problems and is easier to troubleshoot.

I agree whole-heartedly!

There is a difference between your hull being grounded and using your hull as the ground leg of a circuit. Power is going to seek the path of least resistance and a copper wire will have lower resistance than an aluminum hull if it's wired correctly.

Exactly. And ABYC standards dictate the use of a separate ground wire for each device for this same reason.
