The hull of my friends boat (only maybe 6 years or 7 years old) feels soft. It is a Vdrive with auto ballast and has the grate for filling ballast which is the only thing I can think of...... It has never been wrecked and never had any other damage to the hull. Only has maybe 450 hours. Has anyone had their hull get soft? I can push on it and it gives like almost a quarter inch. How would water get in the fiberglass or under the gel-coat? How dangerous is this the keep running it?
