The ultimate 40 cm mast extension with a high-quality, lightweight PLATINUM construction, available as an RDM or SDM version. This allows you to use sails of various sizes up to 3.5 m² with the same mast.
Great product! In my case the fit it's little slight, I had 27 cm long feet. Not a big trouble but with more space there is more water inside the toe of the boot and it's little bit unconfortable for the take off. Anyway I am a beginner so more water in the boots is the last of my problems! ;-)
