Highfield Ultra Lite RIBs and Roll-Up boats are available through Defender. Highfield Inflatables have gained popularity with their unique aluminum transom (on roll-ups) and aluminum hulls. No more wood to rot away! Other unique features include the plastic rowing seat with cup holder, bimini top mount (optional), and fuel tank shelf (UL RIBs). Highfield makes quality control a top priority and backs that with an extended warranty of 5 years on PVC and 10 years on CSM (Hypalon) models.
