Longboards are made for gliding and also planing.So they glide under planing threshold at their best, the priace you pay is that they usually have a little higher threshold to start planing.
Kode Tufskin seems a board born to learn and then planing, it is mainly a planing shape, pheraphs much more lively when planing but imho more slow when under the planing threshold compared to a longboard.
Last a retractable daggerboard is something different and much more convenient than a center fin, imho, as you can change the board attitude from a gliding one to a planing one many times also whan windsurfing.
