Better not get too enthusiastic yet. This is just the weight for a 
non-marinized engine and generator. You need to add the weight (and 
price) of the battery set and propulsion motors, cooling system, and 
whatever control system needed.

Additionally, as this has been designed to be used with a dry exhaust 
pipe and a catalyser, it would be rather inconvenient in a sailboat. In 
a typical marinized engine the exhaust manifold is changed to 
watercooled, this is built with an integrated exhaust manifold 
especially designed to minimize heat losses (i.e. non-cooled!) to get 
hot exhaust for the catalyzer.

So, unless you are going for an Alinghi -style engine installation, 
there are easier choices available.
