The 14 Naish LE 23 is pretty fast in the flats , my old starboard ace was also , but any chop with it and it was hopeless. My new Coreban turbo is also very fast , it is actually the only board I have paddled that keeps going faster the harder you paddle it. I found with some boards you would get them to hull speed I guess and the effort to get them above this is just to much. Only down side to the turbo is that it is heavy so suits a bigger rider. The Lahui boards are also good in the flats. But it always comes down to the jockey
