I was talking to a guy last night, he he'd said that with advances in materials, they can run hovercraft year-round, even in the interior. I was surprised. And then he tells me apparently they'd been running them up on the slope for a while now, in colder-than-Bethel temperatures. Why doesn't anyone tell me these things!
Part of the reason why I've been thinking about hovercrafts so much is I've begun drafting out my next project. While building my kayak, I started dreaming about building a larger boat - not much longer (my kayak is ~17ft), but wider and with a deeper draft. I'd rolled around projects the whole time I was building the kayak, and talked to some pro-ship builders who were generally supportive. I've even go as far as to begin researching, before doing - a novel idea, for me! I found a shipwrights manual from ~1910, reprinted in the 40s, that I've found incredibly interesting.
Interestingly enough, the only legal requirement for a hovercraft is that it have a flashing light.
Maybe it's time to bone up on my aluminum welding? ;)
