Its seems to me that from the write up and things I have read and people I have spoken to that have helmed these boats that,
1. they can be driven either like a shaft drive
2 Like an out drive,
Now this from my point of view,[instructing] means only one type of boat needed to teach both types of boat handling and the fuel economy means this could in theory bring the price of courses down. /forums/images/graemlins/cool.gif or they could pay there instructors more /forums/images/graemlins/grin.gif
At present the IPS system is designed as a replacement for shafts not outdrives, from what I've heard, hitting something hard enough to sheer a leg on IPS, would with a shaftdrive possibly end up losing the boat or at the very least a damaged hull where the P-bracket connects.
Know which I would you prefer.
You can't get away with such a sweeping statement. If it wasn't for women guiding your spending, you wouldn't be able to afford half the things you can now. /forums/images/graemlins/grin.gif
Find just one proven case of disruption of sterngear causing a boat to sink.Of the uncounted numbers of craft throughout known universe using shafts just how many have come to grief.
How do you berth this expensive and complex system on a drying mooring.
With a Volvo sail-drive the oil in the gearbox at the bottom of the leg can only be changed by accessing the bottom of the leg, so you need a lift-out every 100 hours or so. Does the IPS have the same problem?

The product isn't intended for the drying mooring market, but the answer to your question is "the same way you would berth a keel-less shaft drive on a drying mooring"
You mentioned expensive. Is it? I haven't seen prices. When you take into account the lack of need for rudders and boatbuilder-installed steering system, and simpler installation generally, and less fuel per mile OR a smaller engine for the same performance, you'd think it would be cheaper on a proper comparison.
The real cheaper/dearer might be fought out in the used market. If this thing is a lemon, used boats with it will be white elephants. If it's all it's cracked up to be then used boats without it will be (relatively) white elephants. So if you're buying a 40foot power boat say, for 2006 delivery, you'd could do with making the right choice. From what I've now seen, I think I'd chose the IPS over shafts
