The boards are pretty heafty. I usually go to the tip of the board - I've righted my F18 boat three times by myself by standing on the tip (twice with the crew still on the dry hull). It does not give me any indication of being overloaded when I do so (I weigh about 170lbs). However, putting both of us on the end of the board would probably be a bit much but we've never needed to do that.
