In fact, that's a main reason I installed my main battery disconnects in the negative battery cables.
When I've got 'em off - I want 'em all off. When the boat comes out of the water, OFF. Boat in the water - ON. If I ever encounter an electrical problem, QUICK OFF.
Not meaning to beat this to death, but when everything is going well, it would probably not be an issue. If you stop to think about it, you could come up with a host of scenarios where something "Not Good" could come from it. Reminds me of something an old electrician taught me years ago when a 7200 volt cable grounded out and did not trip out anything as it welded the blades in a power center, He said "Always remember, electricity does not always do what it is supposed to do".
An extra measure of safety is always in order.
