Gemini Twin PU Design:

This new pin-tailed twinnie is a blend of retro and modern design elements, built to perform with a heavy helping of usability and fun on top. Featuring a late 70’s / early 80’s beak nose and a flat deck with a stepped rail, it transitions to a rolled flat deck through to the pin tail.

Made to be ridden in small to medium-sized waves the Gemini Twin is a great take on the modern twin fin regardless of your star sign.

Gemini Twin Fin Setup

Use the included performance Keels for drive and hold, or switch to a pair of uprights to tap into a little more vertical performance. Note that the Gemini Twin comes with twin fin boxes only.

PU Construction

Gemini Twin PU construction diagram

Precision-CNC cut, shaped, laminated and finished by hand. With a natural flex pattern and reliable feel, PU has been the standard construction for many years in the surfing industry. While not as durable or as light as boards laminated with epoxy resin, PU performs in all surf conditions and can be adapted to suit a wide variety of surfboard models.

– CNC-profiled, hand-shaped high-density polyurethane foam with a wooden stringer
– High-quality polyester resin and fiberglass hand laminated and sanded to a satin-rub or fully polished high-quality finish
– NSP designed FTU fin boxes (compatible with Futures Fins) on all models

These have long been the standard for most brands and are the most widely and affordable option still out there. Due to the core’s density, a Gemini Twin PU will sit a little lower in the water than a PE board. Similar to the Double Vision, this makes it easier to keep your rail under, requiring less input for slicier turns.

Being a touch heavier also helps PU boards to handle choppy conditions better and are less prone to being bounced around. Sitting lower in the water also has its benefits to barrel riding, providing more hold in hollow waves.
