Siam:

Your most likely capsize will be with the chute up. It's no problem. After uncleating the halyard, the spin retrieval line is right in front of you as you stand on the hull facing the underside of the tramp. Only problem could be if the sheet gets fouled or spin wraps the hull while shrimping; both seldom happen.

From my experience, what matters most is getting the bows into the wind and that there is enough wind to fill the main from the underside. On the occasion that I'm lazy, in a hurry, or managed to capsize when there is little wind; I'll use the board to right her. Others gasp at this but I have had no issues when standing on the boards. It usually is only for 2-3 seconds. I do not need to bounce on the board. I'm 85kg. I'll defer to the Viper sailors but my bet is that it is only a slight difference because most of the additional weight is in the hulls and your standing on one of them already.
