I can duck dive the 9'1" mal if I need to but I'm guessing its less volume that the 125L board. Maybe 90-100L. Probably need to find some locals who might let me try, but I've only seen one guy out here, and its only been a few times.
Based on some volume info for long boards I'm estimating my Mal is 50 - 60L. So I should be alright with something around there about or slightly less from a short board surfing perspective. Its the control when up on the foil that's going to be the challenge.
