The Brewer Thruster fin evolved from Dick’s wide base, which was the “Holy Grail” of fins of the 70’s. They have a 70’s soul with a more vertical rake than anything you are riding today. The Center and Side fins have the same Height ( 5.10”), and Base (4.45”) , dimensions. The center has a 50/50 foil and the sides are foiled to a flat. They are constructed in fiberglass with a white pigment trimmed to a concrete gray. A special “Mahalo” to Gary Linden for resurrecting these templates from his archives.
