Mattp,

I haven`t tried them on sand yet, but they worked well in some muck.

The wheels are actually "dock wheels" designed to move substantial dock systems across the shoreline and stay submerged for seasons at a time. They are supposed to be effective on all shoreline substrates. But, I`ll have to report back later in the season with my first hand experiences - no sand around my home, and the ice just went out of the lake last week.
