Figure 5. Swallow tail aft view. Perhaps the most appreciated attributes of the fish platform involve early wave catching abilities and ease of acceleration. Low overall rocker and a relatively wide tail are the primary design contributors to the fish’s desirable characteristics. Both of these design features are speed and release oriented. Hohar advocates the relatively unoriginal thesis that effective surf craft design balances both speed/release features with control elements. The deep swallow tail, or twin pin tail, depicted above represents a control feature introduced by Mr. Lis in the interest of expanding the fish’s workable range of surf. The wide tail is effectively split into two distinct narrow tails which afford speed control and greater high line stability while still preserving the bulk of the wide tail’s planing surface.
