Advantages- Handling

Great news for devotees of outdrive legs, the handling of the IPS will delight you. And excellent news for shaft drive junkies, the handling of the IPS will charm you too. Low speed manoeuvrability is excellent. In practice, IPS provides all the
"outdrive" advantages of vectored thrust so you can push or pull the stern around and turn extremely tightly using just one engine, or both if you need more haste. But unlike most outdrive setups, IPS also works okay when you leave the wheel centred and use ahead and astern commands as you do with shaft drives. The response is slower but still distinctly shaft-like.

The drive units also have plenty of keel area so they provide remarkably good directional stability. Pottering out of the marina on just one engine required only the slightest deflection of the wheel, and like shafts and rudders, side winds have less effect than on outdrive leg boats. The great thing is that you can pick and choose depending on what you are trying to achieve. Centre the IPS and turn in your own length. Or vector the IPS, tap the bowthruster, and see yourself pulling smartly sideways and backwards or fowards out of a tricky cross tide marina berth. Master the IPS fully and you will be giving those implausibly manoeuvrable twin jet-drive boats a run for their money.At high speed, the good directional stability remains. Rudders work well at medium to high speed but IPS permits a tighter turning radius and better speed through the turns because, like outdrive legs, there is nothing blocking the prop wash.
