It wouldn't matter if you locked down your centerboard because it's the water ballast that will bring you back if you get knocked down. I can only see negatives to locking the centerboard down in your skinny water. The centerboard is there to help against drifting to leeward, not for its righting ability.
I once was told the centerboard had a 100# weight in the tip--just enough to get it to go down and stay down, but negligible ballast. I suspect a lock could cause unnecessary damage if you struck something.
This seems to fall into the "if it aint broke don't fix it" category or some such thing.
One of the best things for those of us who sail on "thin water" is that the CB is free "kick up" which it couldn't do if it were "locked" down. A "self-adjusting" feature if you will.
