The twin fin surfboard offers increased speed and maneuverability while also being more stable compared to a single fin. This board design also produces a looser board than a thruster. Twin fin set ups are mostly seen on a traditional fish or a more modern shortboard shape. Their quickness and ability to make sharp turns makes them a great choice for small conditions, but they can also be used in medium sized clean surf. Looking for a deal on fins for your surfboard?
