Sail drives vs shaft drives?
I keep seeing the vast majority of boats equiped with 'saildrives'. I have not really been able to figure out the difference between a saildrive and a shaft drive other than seeing that shaft drives are apparently 'better'. What exactly is the difference - props are obviously connected to a diesel engine via one of these two methods I assume but if shaft drives are indeed 'better' why do I not read more about them. It seems almost all boats I have seen mention saildrives.
Does it impact the prop location? Higher/lower? Does it impact weight? About all I know about shaft drives was that my old Yamaha motorcycle had one and that shaft drives on a motorbike were more reliable than chains.
Thanks and regards for any thoughts or good links!
I kept digging around I came across comments comparing a couple boats and this person mentioned the following......
"stay very very far away from anything with a saildrive" was the opinion and went on to describe that saildrives are aluminum housed below the boat immersed in seawater which, when it fails requires hauling the boat. They are easier to build and leave more room inside as well as gets an engine out of an aft bunk (or two in a cat). I gather from the comment that shaft drives though ar easier to fix, less likely to break and don't expose a prop as much (although don't go snorkeling near the back of the boat maybe or you might get sliced up??).
