The AM Twin + 1 is the original twin template from the CI brand. This twin set is designed for speed and quick and easy turning.

Overview

This twin template has a robust base which produces exceptional drive, and a very tapered, narrow tip that releases fast and easily when turning off the top.

The low sweep of this twin template means it stands very upright, helping the board to pivot in a very tight radius while minimising drag. The side fins also sit quite deep in the water which adds an underlying feeling of stability when driving through more powerful turns.

The trailer fin is offset from the standard shapers dot position, and has been moved forward on the fin tabs. This essentially tightens the overall fin cluster making it more usable on twin + 1 models and hybrid boards such as the G-Skate and the Rocket Wide.

Board Types

Performance Core

Performance Core (PC) fins are made using a multi-layered resin transfer moulding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light and can be used in a variety of different conditions.
