That force will act roughly 1/3 the distance from the hull to the tip giving a 384 ft-lb moment. For an equivalent moment, you could have a 128 lb person stand on the very tip. Factoring in structural safety factors, a higher design speed, etc, etc, etc, it looks to me like the dagger would be plenty strong enough to stand on.
Steve, why 1/3 the distance? Most boards are straight section and not tapered.
After seeing the hell my boards were going through at Performance Race Week last year (boat leaping clear into the air in 4' waves and coming back into the water sideways) I didn't feel to worried about putting my full weight on the tip! Most boards are designed with a pretty big factor of safety.
