Wonder what the durability and replacement costs of the "hulls" would be. If they sold these in US, probably have to wait six months for replacements to arrive. Which is about how long it takes to get some locally made parts anyway...

Looks like a good choice for just a day out. They do a good job of showing the assembly and parts setup.
