Hi ProPhoto_56401, Thanks for your question. The most significant difference between the two, is that the Island Voyage2 kayak is designed with a durable outer cover, made of PVC tarpaulin and hi denier polyester. The air chambers are inside the cover and are much more protected from abrasion, etc. In contrast, the Intex Explorer2 is constructed of a single layer of vinyl. The hull of the Island Voyage2 kayak is made of a durable PVC Tarpaulin which is two sheets of PVC bonded to a fabric mesh. Designed to take the abrasion of rocks and beaching. The inflatable floor chamber sits on the inside and is covered by a fabric top cover, so you can take you dog with you and not worry about its nails. This kayak also has a removable tracking fin for improved tracking. You can paddle solo by moving one seat to the center buckles. Thanks for your question!
