I recently broke the mast on my Viper 640 monohull, and I'm thinking about putting an ARC-21 rig (mast, boom, and sails) in as a replacement / upgrade. The goal is to fire up the boat with a bigger and more powerful sailplan, and to get 2 trapezes.

I'd also like to put on a MUCH bigger asymenterical spinnaker than the ARC-21 carries.

- Any thoughts?
- Any feedback on how good the ARC-21 rig is?
- Would this kind of rig support a MUCH bigger masthead-rigged spinnaker? I'm worried about what keeps the rig from breaking (going forward) since there is no backstay.
- Suggestions on alternative rigs I should consider?
- Has anyone tried something like this? What kind of issues am I facing?
- How bad an idea is this?

A picture of a Viper 640 is attached ...

Thanks
Jeff
