The Fin
Alex Lopez's Diamond Twin, Futures compatible solid fiberglass in clear or brown.
Lopez surfs and shapes in San Diego, and the Diamond Twin is his own twin template — a 5.48" base carrying 5.25" of depth, so the base is slightly wider than the fin is deep.
How that reads
A base wider than the depth is a drive bias: the fin generates speed down the line and holds a long arc, rather than pivoting tightly off the tail. It is a twin for surfing through a turn, not for snapping out of one.
Who it suits
Fish and twin-fin boards, especially in waves with enough face to draw a line on.

What people say
Nimble and quick under the feet, with a forward leaning wide point and pulled in tail. It's skatey, lively, and, thanks to the winged diamond tail, turns a little more on pivot than a swallow tail or rounded pin.
Quick acceleration, easy rail to rail, plenty of hold — working across round pins and long fish to performance twinnies.
Lopez shaped the board, then spec'd the fin to go in it — if you're on an Alex Lopez board, there's no compelling reason to second-guess that starting point. Beyond his boards, it's right for any wide-point-forward twin or diamond-tailed fish where you want acceleration with actual redirectability, not a keel lock-in. It sits in the middle by design.
More About This Fin
A solid fiberglass twin fin designed by shaper Alex Lopez for his Diamond Twin surfboard model and produced by True Ames in a Futures-compatible base. It measures 5.35" base by 5.25" height, a nearly square aspect ratio with a fuller body and a narrow, raked tip — more base than a typical upright twin, less than a keel. Lopez recommends the fin across his Diamond Twin, Grand Twin, Kinky Fish, and LT board templates, which span roughly a 5'7" performance twin to a 6'8" longer twin; True Ames lists it for round pins, long fish, and performance twins.
