Really a design change? Are the cross beams OK?

Tiki 30 crossbeam
After studying the cross beams some more I think I'm comfortable with them. They appear to be an I-beam but with fairings. I believe that if I install some 6oz cloth on the lower surface extending over the vertical beam's horizontal components then the possible rot issue would be solved. In my limited wood/epoxy experience rot happens when water sits on a piece of wood that has only epoxy coating not on one with a minimal layer of cloth over it. My guess is the wood expands/contracts with heat and opens up pores. Also the end grain deserves special attention.
