Unfortunately, I am a better builder than artist. My "sketches" usually need a translator.
As for basalt, it's not here yet in my opinion. I LOVE the concrete reinforcement products, but the price and performance niche that the impregnable fabric occupies for now is not attractive. Yet.
It has the potential to have wider acceptance in the market, but for now.....if performance boatbuilders are using S-glass and carbon fiber instead of basalt, there's likely a reason.
The folks here -
Basalt fibreglass - have a nice discussion about it.
