505 Builders

Trap twings are a device which moves the trapeze take off point further up the mast to support the mast top when the kite is up.  Remember when the 505 switched to the monster 6m kite it moved the kite halyard take off a metre up the mast beyond the hounds.  There are a couple of different systems, auto twings which move the take off when the kite is raised, or a simple system where you release a cleat.  They are needed as if you just had the trapeze take off further up the mast the crew weight does funny things to the rig and without them there is a good chance the rig will go over the bow downhill in waves

What are "trap twings" (apparently an alternative to double spreaders)?

Van Munster still build boats, very well built carbon pre preg. 

I was  trying to find gear guides but seem to struggle. Where are they all built? Never herd of Van Munster.

Pabs a rondar 505 post 8400 number is going to be what your after or a krywood of similar vintage.  Waterat hulls seem very quick and sought after over the pond, so I imagine there will be a few of them about.
