That's a GREAT score! Perfect time of year to ride one too.
I had several fishes back in the day. VERY maneuverable........VERY fun! In Florida they were REALLY practical - especially in the summer - on those days when there was only a ripple or small swell to eek out some rides. Those fishes didn't take much to propel them. You could ride waves all the way into shore.
We had some that were like tables, they were so wide.
Here's me (right) and my buddy "Big Jim" with our fishes approx. '74.
