At Mainfurl you can choose between 3 different covers
The cover is built in Weather max, and you can have it in either black or light grey (silver). It is fitted into the grooves on the chafe guards, and it stays permanent.
It is operated by a endless line at the mast, so it is easy to handle on big boats and catamarans where it is hard to reach the boom.
Together with the cover, the boom comes with the sporty looking integrated end cap.
