Recycling Massive Ct40 Battens

In this episode, we’re diving deep into a serious carbon fiber upgrade session. First up, we check out the tricky installation of a curved carbon-nomics panel into the cabin top (big shout out to Shane for getting that twisty piece in!). We’re sticking to our boat-building standard: if it’s black, it’s bonded with epoxy and carbon. Then we’re breaking down these incredible @C-TECH CT40 sail battens. Shayne explains why these aren’t just any carbon tubes: - How they are custom-designed for specific sails (even down to the individual pocket!). - The science of "hoop fiber" vs. "unidirectional" layup. - Why you can't just cut them in half (splitting them ruins the stiffness and causes twisting!). - How we are repurposing these high-tech race boat battens for our cruising boat. Where are we using these? - Compression Post: Future-proofing the mast base. - Push Pit: Building a carbon push pit (sorry stainless steel guy!). - Starlink Mount: Using Carbon c-tech battens for the post. - Cabin Top Stiffening: Attempting to recess these into the ceiling for wiring and strength. - Transom Beam: Stiffening the back to handle a traveler track.
