Back in 2000, I was unloading the FX-1 @ Daytona. There was a black guy from Maryland visiting with his family. I talked to the life guard at the entrance ramp before unloading - LG says I'll bet I will have to go get him shortly. I asked why, LG said black people tend to be thicker or denser in mass even @ the same weight.
Sure enough, before I could get in the water, LG was out there pulling the poor guy out and chasing down his sea-doo. The black guy rode parallel to the beach / waves, nice head hi set with a lip rolled that doo right up big time in shallow water. Big scene with his family there freaking out but not necessary.
