any idea of the cost of ownership of a single vs double engine boat?
total maintenance, gas consumption? benefits or penalties?

THanks all....

Good question. There are safety aspects to twin ownership - mainly
having a spare engine available in particular if you are planning on
running any distance off shore. I think you were looking at a boat in
the Long Island area if I recall. That part of the world, twins if
you are getting offshore a little ways.

With respect to costs, well two times everything in terms of
maintenance. I've got triple ETECS, three times everything in terms
of costs. Only makes sense.

Complexity? Not really - seperate engines are generally seperate
systems with the exception of the electrical stuff - that can get
complicated with more than one engine depending on how the boat is
wired, but usually seperate systems.

It's a trade off in a number of areas - safety, convienence,
speed/weight ratios, etc. One more of anything is going to cost you
additional money.
