Optimax MK IV Boom 45 mm

Optimax MK IV boom with a diameter of 45mm. The boom is perfect for sailors who are heavier than 45kg. The MK IV boom is slightly stiffer than the MK III model. As a result, it is less flexible and bends less in windy conditions and when hiking. As a result, the sail profile is less affected and it retains its profile, allowing heavier children to make the most of the wind. All necessary cleats and sheets are already mounted . The sheets are made of high quality Dyneema material and hold perfectly in the cleats.
