fiberglass isn't that durable either. they crack on impactI just hope it's a durable hull, not sure how to find out, only way will just be through experience i guess.
thats true, but we're talking about extremes. The Sparks hull won't see the necessary heat to warp the hull, at least not on the water. Same with cold, it would need well below freezing temps to induce the hull to crack.fiberglass isn't that durable either. they crack on impact
plastics have a bit more flex before they crack
so I guess thats a good thing? Though plastic is not as good at maintaining its integrity when it comes to changes in temperature.
