Abstract: A telescoping mast for conversion of a sailboat. A mast consisting of two portions--an upper telescoping portion which is journalled to telescope up from and retract down into the lower portion (trunk). The mast is located somewhat midst to forward of a sailboat where it is supported by a tabernacle (base) which allows for pivoting of the mast back and down toward the cockpit. The mast is also supported by cables (i.e., shrouds and stays). The said telescoping portion is raised by a line (rope, cable, etc.) attached to the bottom portion of said telescoping portion and runs to the top of the said trunk (lower portion). The line then is captured by a pulley whereby the line is redirected down the outside of the said mast trunk to the deck area. The telescoping portion, when extended (telescoped), is secured in place to the said trunk portion by a pivoting fork journalled within the said telescoping portion.
