[C320-list] Rig C320 for Asyn Spinaker

[Guy Smith]

Hey All,
I'm able to borrow an Asymmetrical Spinnaker from my Dock Neighbor to try it out before I consider buying one. My experience with Asyms has been on boats that had a toe rail with plenty of places to sheet the Spinnaker with clip-on snatch blocks. My guess is that, without installing some custom track or toe rail, I'll need to use the aft dock line cleats. 
Does anybody have a recommendation on how to attach the snatch blocks I'll need for sheet control?I don't want to beat up the deck with snatch blocks bouncing around.
Also, any recommendations on how to attach tack line hardware would be appreciated. 
I hate learning my lessons the hard way... Let me know what works for you..
Thanks...
Kind Regards,~g
