Finally someone that might be able to shed some light on this...

When snowboarding I seem to be able to go faster than alot of my mates, could never figure out whether it was my weight or board, I thought it was my weight, often using the phrase "gravity is my friend" however they debated that items of equal density will accelerate at the same rate etc and that whatever weight advantage would be counteracted by lack of aerodynamics.

So what is it? I also wondered if in a small way being heavier would compact the snow/ice harder thus creating less resistance between board and snow?

I am not a scientist.

I too am faster than my fellow boarders, but of equal or less weight and height. I put it down to my board being fucking quick. (Ride Timeless) Not my fatness.

Rolling mass is a bit different tho, I guess a bigger ball of snow rolls further and faster than a small one down a hill right? Something to do with momentum and stored / collected energy?

So the bigger rider could have a higher momentum gain culminating in a higher acceleration? and speed?
