the only thing is that most Saber 28's I have seen have been rigged with twins.
I honestly dont see any point, aside from the fact you can get home on one engine, to running twins in a style of boat that runs so well with a single. If you are offshore running OK but where I boat in the big lakes a tow or help is usually close by.
I would only buy twins if I was buying a bigger boat that needed them to run properly.
