Rod,

Several years ago when I was researching what boat I wanted to have as
a passagemaker, I found many very good advantages for a catamaran hull
and only a few disadvantages.  The first disadvantage is transient: it
is a developing market here in the states and resale would not be as
good for the time being.  Also, finding marinas that could accommodate
the extra width of a cat might be a slight nuisance.  The one
disadvantage that kept me away from a catamaran is hull slam in a heavy
sea.  I know that many cats have anti-slam nacelles to redirect the
water, but it still remains a problem.  I was reminded of this a week
ago in Maui.  I was diving with one company at Molokini and noticed a
very good looking aluminum cat also conducting  dive operations.  I
asked my captain if he had ridden on that cat in heavy weather?  He
laughed and obviously figured out what I was getting at.  He replied
that the boat in question had to be sent to Oahu earlier in the year to
have its hull re-welded to the pontoons.

Is there anything on the horizon to address this problem with
passagemaking catamarans?  I own a mono hull with a bulbous bow.  When
we are cruising in seas heavy enough to lift the bow out of the water,
we get bulb slap which is obnoxious in its own right.  I am
considering moving to a mono hull with a fine entry bow.

Anyone on Power Catamaran List have any comment?
