While Marstrom has a snail on his unirig designs, he has a brand new hard integrated snuffer/pole design for the Tornado this year. The design looks remarkably similar to what Lovell & Ogletree had on their boat, and has 4 advantages over other designs that I can see:

• It keeps the water out.
• It is more streamlined.
• It acts somewhat as a jib endplate.
• It is stiffer, for less dynamic losses in puffs.

I guess you can't really put a snail on a boat with a jib.
