These Line Control™ Whisker poles offer just the right blend of aluminum and carbon structures to provide the racing or cruising sailor weight and cost savings. They have the strength and weight savings of carbon on the inner tube and the abrasion resistance, durability and cost savings of aluminum on the outer tube. They also feature Forespar's exclusive "Ultra" end fittings (UTS socket inboard and UTR trigger outboard) for further weight reduction and ease of maintenance.
