Mast base for rig of centerboard boat, has upper end with housing for receiving top part of mast, and metal part with sail fitting fixation device e.g. gooseneck type boom fixation device, for fixing gooseneck type boom of centerboard boat

摘要

The base (10) has an upper end with a housing for receiving a tubular top part (3) of a mast, where the top part is made of fiber e.g. carbon fiber, glass fiber, aramid fiber or Kelvar(RTM: para-aramid synthetic fiber). A metal part has a sail fitting fixation device e.g. gooseneck type boom fixation device, for fixing a gooseneck type boom (2) of a centerboard boat (1). Height of the base is less than or equal to thirty two times the value of a diameter of a circle circumscribing the base, where the height of the base is equal to a height of the fixation device. An independent claim is also included for a transport unit comprising a sail.
