Yes, I've seen that before. I could have sworn I had a picture of it in use, but I can't find it.

All it does is make the mast longer so that the ends of the shrouds and trap lines can be attached to the t-bar for trailering. Just another example of the inventive nature of the sailor.

If anyone can find a picture of this on my site at http://www.thebeachcats.com/catamaran-pictures.html please let me know. It's bugging me that I can't find it, but there are now over 6,000 pictures there.
