I was looking at a little round nose fish, similar to what I'd seen in lost' 5'5''x19 1/4. It's a standard thruster fin set up instead of twinner. I think the dimensions were 5'4''x19 7/8 x 2 1/4. I'm 5'8'' and weigh right around 150. That little board looks really fun but I'm curious if that's enough volume for an intermediate surfer of my size? Thanks.
