Forgive the ignorance, but can anyone please enlighten me as to what sail-drive is and how it differs from other forms of mechanical propulsion?
Many thanks

Sail drive is a cross between an outboard and inboard, the "leg" which looks a little like an outboard lower housing, sticks out under the boat, in front of the rudder, fitted to a flange on the hull, it doesn't turn, the rudder steers the boat. A right angle drive gearbox, allows the engine/gearbox assy. to be mounted on engine beds and connected to this drive, which in turn drives the prop. Like turning the power head on an outboard through ninety degrees and putting it through a hole in the bottom of the boat. Volvo are famous for theirs. Not sure if theres a website you could look at, but you could try"Volvo saildrive" and do a search. I hope I've made some sense.

As Colin says, you tell a sail drive because a big hole was cut in the bottom of the boat and the bit that looks like a outboard stuck through the bottom. The engine and gear box sit on the dry side of the hole. The hole is then, obviously, glassed up. Typically, people antifoul the patch a different colour - I have no idea why.
The type of boats that have saildrive are mainly fin keel. Most racing boats have a saildrive (usually Volvo or Yanmar) and a folding prop.
The traditional power option differs in that there is a distinct prop shaft with usually a fixed prop.
Don't ask me about the various merits - this is from observation only.

There are some pictures on Bukh's website here...

Some of Bukh's saildrive arrangements use a vertical crankshaft engine like an outboard, so there is only 1 gearbox rather than 2.

Re: ALL WRONG!!

Now you are just being silly. Everyone knows it's one of them package holidays where you take a cruise ship to somewhere and get a hire car while you are there. Now stop trying to confuse everyone.
