 This is the device. Simply the sinker is attached to a messenger line (fishing line in my case). the messenger line is held tight, and as to stay snug against the tube. (the tubes diameter is smaller than the sinker).
 When the tube gets into the hole at the top of the mast, the messenger is released and  the sinker pulls the line to the bottom of the mast where it can be pulled out through the hole with a hook.  then the messenger is tied to a halyard rope and fed back through the other way
 the runners go up through the mast like the sail keeping the device close to the mast,
