I don't know anything about Dynaplates, but if it's on the hull, it's

That hole in the water is pretty important. It not only allows the
plate a few feet down on the hull to make a good connection, it also
makes the boat float better.

I'm sure sooner or later someone will tell you there isn't a hole
because where they put their boat, because when they take the boat out
of the water they can find the hole.
