Channel Islands H4000 Longboard Model Description: The H4000 is a lower rocker offspring of the custom only H-2000 teardrop outline. The lower entry allows for easier paddling and glide into waves as well as nose riding in small surf than our H-2000 did. Comes standard with a single stringer. Recommended as a single fin with side biters. Experience: For riding a longboard in better, steep face waves. Ideal Wave Size: Ankle-high to Head and a half.
