Can any board be ridden as a single fin? I have a 8' Stewart Funline 11 I am going to swap in a 9 inch fin instead of the 2+1 fins that came with the board. I also have a matador 9'2 east diamond tail longboard that is sold as a 2+1 board. Interested in any opinions if any board shape/length can be used with a single fin. I know the answer is likely just try it and see, but i think some board makers advertise some boards 'can be ridden as a single fin' and don't make the same statement for other boards.
