Serious Props

I just received my new Campbell Sailor prop. Is it odd to be so excited about a mechanical device? It's partly because the old prop is corroded and potentially a danger if it were to break during a family outing. It's also because this brand of prop is designed to give much more thrust at the smaller size, and for a fixed three blade, it doesn't drag as much when under sail as a standard one. 

Now to find out when the soonest our newly sourced diver can get it on Hideaway. 

Here are some photos of the new prop. It's surprisingly heavy and the machining to get it to my boat's specs are evident. At the bottom is a graph that shows the efficiency of this prop type over other fixed blade designs.
