go to
http://www.image-ination.com/sailcalc.html and you'll see the
motion comfort is low compared to similar sized boats and the roll over
ratio isn't the best.
But then there are J-Boats with even lower comfort/capsize ratios that
are taken offshore with great success. True, the H34 is no full keel
heavy displacement boat, but it's also faster in many situations and
has it's own strengths. There are some folks who have no problem with
the idea of taking a J30 on a long voyage...and others who wouldn't
think of it in anything less than an Alberg 30. Two very different
boats and the J is certainly missing the numbers associated with long
range cruising.
In the end it's up to the sailor.
