Product Description

The Dark Twinn was developed as part of Aipa’s Dark Series, a series of new designs inspired by Ben Aipa’s classic shapes and modernized for futuristic surfing.


The Dark Twinn combines Ben’s Wing Twin template, used to make Dane Kealoha’s twins in the late ‘70s and ‘90s, with an updated swing twin squash template for a modern feel. The shift in wing placements engages the wing-to-fin relationship and accents how the board performs as a twin fin.

Featuring mid-range rockers and a lowered rail apex line, the Dark Twinn is a high-performance groveler built for aggressive surfing in soft waves. A staged bottom contour with a blended roll from the nose down into a single concave under the forward foot transitions into a double concave that is deepest between the forward fins. The concave then blends with a healthy amount of vee/double-concave, starting at the wing, and easing through the tail.

The Dark Twinn is a lively and responsive board proven from Pismo Beach mush to juicy Hawaiian surf.
