The Fin
A 2.5" centre trailer — 4.88 square inches of fin — for the fifth box on a quad or the rear box of a thruster.
2.50" deep on a 2.62" base, in solid fiberglass. It is a centre fin small enough to change how a board feels without adding a fin's worth of drag: run it as the fifth fin behind a quad, or drop it into a thruster's rear box in place of the standard trailer. The foil section is ultra thin, which is where the low drag comes from.
How that reads
A trailer this small holds the back of the board together without steering it. In a five-fin box it settles a quad down and gives the tail a point to pivot on; in a thruster's rear box it takes area out of the back of the board, which loosens the tail and shortens the turn. Less area also means less resistance, so nothing is paid for in speed. The FCS base has a single tab rather than two, so it can sit in either slot — forward for one drive characteristic, back for a bit more drive.
Who it suits
Quads with a fifth box, twins with a centre box, and thrusters you want freer off the tail. If what you want from a centre trailer is hold rather than release, the 3.3" is the bigger one.
If this is not the one
Want hold rather than release? The True Ames 3.3" Trailer Fiberglass (FCS). Want a trailer that flexes and springs back? The True Ames PT-1 (Greenough Power Trailer) (Futures).

From True Ames
Foiled ultra thin so it cuts drag — the trailer adds stability and a center pivot point without the speed penalty a fuller fin would bring.
Our take
Add this trailer behind a quad or twin when the board feels too loose in bigger or faster surf and you want a center pivot point without losing speed. Slide it forward for looseness, back for drive, and expect quarter-inch moves to matter — it tightens the tail without turning the board into a thruster.
More About This Fin
The True Ames 2.5" Trailer is a small solid-fiberglass center fin with a single-tab FCS-compatible base, used as a fifth fin behind a quad or a stabilizer behind a twin. The single tab allows mounting in the forward or rear position of the plug. The foil is ground ultra thin to minimize drag, and True Ames offers the same trailer with a Futures base for boards with Futures boxes.
