The Fin
The 3.3" Trailer is the bigger of True Ames' centre trailers — a 50/50 foil drawn to add hold rather than take it away.
3.30" deep on a 3.28" base, 8.35 square inches, solid fiberglass with a raw sanded finish, in smoke. It goes in the rear box and it goes both ways: behind a twin when the tail lets go earlier than you want it to, or into a thruster's rear box in place of the standard trailer when you want a smaller fin back there.
How that reads
A 50/50 foil is symmetrical, which is what a centre fin wants — it behaves the same on both tacks and adds drive without trying to steer. At 3.3" there is enough area to be felt. Behind a twin that reads as stability and hold; in a thruster it is still less fin than the standard trailer, so the arc shortens without the tail going vague. The template is drawn for drive and reliability rather than release.
Who it suits
Twins with a rear box ridden in surf with some push, and thrusters you want a smaller trailer in. If the fin is going in a quad's fifth box, or the point is to free the tail up, the 2.5" Trailer is the smaller, thinner one.
If this is not the one
Want the tail freer instead of more locked in? The 2.5" Trailer - Futures Compatible (Solid Fiberglass). Want a trailer that flexes and twists? The True Ames PT-1 (Greenough Power Trailer) (Futures).

From True Ames
Slide it forward for a looser feel or keep it on the back tab for more drive — it's built to add or subtract a small, precise amount of fin rather than to be the engine of the board.
Our take
Buy this if you have a twin that washes out in size or a thruster you want a little looser off the tail, and you want to test that change cheaply before buying a whole new fin set. It's the precise, low-stakes dial — if you're chasing real added drive and hold, a bigger trailer or full center fin will do more.
More About This Fin
The True Ames 3.3" Trailer is a small single-tab center fin in solid fiberglass, FCS-compatible, designed to drop into the rear box of a thruster, quad, or twin setup. The compact template has a small footprint, and the single tab allows it to be positioned forward for a looser feel or on the back tab for more drive.
