| Barton Boomstrut to 9.0mBoomstrut to 9.0m                                             Six sizes to suit yachts up to 12m/40ft LOA                                    Patented flexing spring provides fast response and a constant force for  vang efficiency                      The boomstrut's lightweight, low-profile design features two flexible coated  fibreglass rods which provide the force to support the boom. Pulling the boom  downwith a conventional kicker causes the Boomstrut to flex upwards; releasing  straightens the rods, thereby lifting and supporting the boom.                                    Maintenance-free, durable design                      Eliminates friction and sliding parts.                                    Improved performance                      Less weight and windage                                    Easy installation                      There's no need to replace your existing hardware - the Boomstrut mounts  independently inside the existing kicking strap tackle.
