The Severne Cyclops HD RDM mast extension is a lightweight and strong mast extension for RDM wave masts, available in alloy and carbon versions. The alloy model (24 cm: 0.66 kg, 36 cm: 0.76 kg) is an affordable and durable choice; the carbon version (24 cm: 0.48 kg, 36 cm: 0.58 kg) is significantly lighter for windsurfers who count every gram. The Formuline downhaul line offers minimal stretch and reliable power transfer at any sail trim.
The compact, wave-optimised design fits snugly onto RDM masts and provides a tight, play-free connection. The extension is compatible with the full Severne wave range and fits all standard RDM masts. A solid component for the windsurfer who wants to rig quickly, comfortably and accurately on every session.
