My Understanding is that if it is not directly addrerssed in the rules you can do whatever

I spoke with Rick yesterday afternoon. He says it's not legal to use CF inside a mast. We can use only aluminum and/or wood inside the mast. However, mast accessories such as jumper struts and the masthead crane CAN be made of carbon fiber. I accept El Capitan's interpretation, but don't really understand the difference... doesn't the mast stub serve the same purpose as a jumper strut?

Good question about using carbon for the deck support structure. I'll ask. My intent IS to use carbon for a lot of what holds my deck up and on; i.e., the side strakes, and most of the deck-support ribs. CF weighs about the same as heavy balsa, but is a lot stronger and stiffer. My plan is to cut balsa bulkheads and use them as one-off forms for CF replacements. I guess I better ask first... [;)]

Hi Jim,

All my Deck beams etc are CF.

It is heavier than Beven glassed balsa....even with the lightening holes I put everwhere. Maybe an ounce.......bright side....it is 20 times stronger and will never rot

Doug: What's Beven glassed balsa? --Jim

[Doug Wotring]

Beven, is an exaple of my poor typing skills.

even glassed balsa is lighter than the CF beams I made....
