Looking for the learned opinion of some of you design gurus: What’s the real deal with a channel bottom (typical six channel type thing, nothing too extreme)? Design theory, benefits, detriments, etc. Just a marketing thing? One of the best boards I ever had was a channel bottom. (Early/mid-80’s, 6’ single fin rounded pin, w/flex fin–was looking for alternative to multifin at the time.) Don’t know how much the channels had to do with it, but thinking about going this route again . . . . Thanks.
