Awhile back mention was made of the motorsailer "MitSeaAh"
Did anyone take notice of the fuel burn on this monster??

I would venture to guess that the alternative big catamaran design might
have
only required twin engines as small as 600 HP.....or lets go with a big extra
margin and chose twin 1000 HP's. Total, 2000 HP verses 7000 HP!! Quite a
difference in fuel needs, weight needs, space needs, and propulsion gear
sizing and configuration. And what about all of that extra aux power required
to run the hydraulics required for MITseaAH's trim tabs, auto-gyro flaps,
controllable pitch props, keel control, extendable mast, etc, etc I know
which
vessel I would rather be charged with maintaining in good working order.
Please excuse me just a moment while I digress to consider the fuel needs of
these big engines. The owner looks forward to trips from Long Island, NY and
Newport, RI to Bermuda. I believe it has been estimated that MITseaAh will
burn about 60 % of her fuel load on this 25kt dash out the 630 miles from
Newport to Bermuda. That works out to about 122,400 gal or about 200
gal/mile.
At an average approaching $3.5 per gal (between here and Bermuda) this trip
will run about $428K per one way trip. I'll bet we could have cut this bill
SUBSTANTIALLY with the catamaran hull form. And we might have been capable of
maintaining a higher average transit speed in adverse conditions.
