The Stryker PRO 320 inflatable boat comes with the added protection of 1.8mm wrapped with our Stryker Shield® under the entire bottom of the boat. There is no other comparable boat on the market today. We add a 20” transom for the ability to add a JET outboard for extreme shallow water use. Please note: this model requires a 20” shaft outboard (long shaft). This is the perfect inflatable boat for 2 adventure seekers paired with a 9.8HP long shaft outboard.
