hull design, heavy weather and effeciency

If I was going to buy a voyager, I would consider building from
scratch and having different design characteristics than the current
generation of production boats.  A friend has a boat (began life as
a racing sailboat--at 55 feet, 18,000 lbs, draft 4 feet (dagger
board up), beam 12.5 feet.  Later in life it became a cruising
sailboat--and the weight went up to about 28,000 lbs.  The boat was
repowered from 50 hp -which gave a good cruising speed of 8 knots-
to 112 hp and how a cruising speed of 10 to 11 knots.  The hull form
is such that the boat begins to lift and semi plane at low speeds.
This boat has circumnavigated twice, plus another 100,000 miles and
is well proven.  This hull form could be built as a power boat from
scratch.  It behaves very well in heavy weather and is able to make
good way into 10 foot seas and 55 knots of wind.

All these features may be wonderful, but the market has little
interest in passagemakers with 12.5 feet of beam (which would mean a
boat three feet narrower than a Nordhavn 46!).

Even with powerful promoters like Steve Dashew entering the picture,
I seriously doubt long and narrow designs will ever become popular.
The market wants for more from its boats than hull efficiency.
