STANDUP PADDLE MAGAZINE More Pro(fessor) Box Larry testing. The John Becker fin and history. I think all of Larry's race keel fins derive from the one he made for John Becker. Not certain but I think it's a good conclusion as the race keels all have that "JB" feel. Still one of the most ridden of what I have taken out, that JB fin works in fl...ats, open water, surf.Now, (don't know what to call it but is says mini-race keel) JB Jr. I took it out today for 30 minutes and this one was super fun as well. Don't think it'll go in surf (still have to try it) but it goes in flat water. Good straight line but with more looseness going around buoys.
