How many tons of water are soaked into the hull? Probably zero but you never know.

I have never heard of that before.

Are Velocity still balsa wood core? If so, even if not, they can soak up water and get slow. Its unlikely for a newer boat tho.

boat should pull a 26 hydro with out a problem that is what came stock on it. mine had a 365hp mag in it stock and pulled a 24 hydro 5200 at 68 mph and that motor was tired
