Worlds largest solar powered boat
Discussion
I was in Nha Trang in central Vietnam at the weekend and spied this in the local harbour.

One thing I noticed on the boat when i saw it and also in the link, is that the props are only about 50% to 60% submerged, is this efficient? Shirley they need to bite at 100% if its going to be of any use.

That is very very cool.
Regarding the props, No they don't - many many (Cmndt Lassard) high-performance boat run with surface-piercing props, even some outboards will be designed to run like this for example the Mercury XR2s....
It's all about the design of the prop and engine revs.
Granted it seems counter-intuitive, in this case especially so, as this thing doesn't look as though it'll plane as such!!
Unless it's omething to do with load? An un-laden cargo ship would often have some prop out the water whilt floating at a dock side.....
Thanks for the link though!
