It’s been 94 years since Uffa Fox built the (planing) Avenger and thoroughly destroyed his British competition on the Isle of Wight. And then took that little 14-footer across the channel to do the same to the French.
All because the elitist snobs didn’t want him to join their club :)
This is true for any rigid body traveling through a fluid. It comes up in ballistics too.
Is there a simple explanation for this to share?
Friction and stiction due to area is a greater killer of speed than weight, which will only put you a bit lower in the water.
It is obviously a lot more complicated than that. Enough weight will sink you and more length will slow your descent to the depths a bit. Greater weight will increase inertia so acceleration will take a hit. Depending on how the weight is distributed you risk turn over due to your meta centre being in the wrong place in relation to your centre of gravity.

The opposite is true.
The longer a hull, the faster a displacement vessel can travel. Here's an MIT explanation: https://engineering.mit.edu/engage/ask-an-engineer/what-is-t...
