Hi Tom,
I'm up at Bear Lake as we speak--drove by and saw your Stilletto moored.
Definitely get a Hobie 16 or Prindle mast and just transfer your hardware over. I'm sure you, of all people, could make it work. Today I saw a couple of masts "available"...a Prindle and a G-cat abandoned in a field just of the road between Fish Haven and St. Charles.
