The main disadvantage is that single shaftdrive boats aren't as manoeuvrable as twin-engined ones or those fitted with sterndrives or outboards.
There are millions of yachts out there with this set-up, and they seem to manage okay, so what's the difference? Well yachts usually have deep keels and larger rudders to give maximum stability and steerage at speeds below 10 knots. Motor boats on the other hand tend to have shorter keels and smaller rudders to reduce drag and steering effect at speed. The flipside of this is that they also have less directional stability and steering effect at lower speeds, making them more sensitive to being blown about by the wind.
So before helming a single shaftdrive boat, it's worth finding out a bit about its hull shape.

Lofoten or Bust- Part 4- Grandezza owner Per Harrtoft heads back to Sweden after an epic 3500nm adventure deep into the Arctic Circle to visit the mythical Lofoten islands
After ten memorable days in the Lofoten Islands in the far north of Norway, we are on our way back south towards Sweden. We have already made it as far as Trondheim, a charming place even if it was raining so hard we had to cycle round the city centre clutching umbrellas. But now we are back on board Deamare, our Grandezza 40 Fly, eating up the miles at a steady 31 knots.
