Jim,
Waterline length is actually a rather poor indicator of performance and is only
useful when comparing boats of similar design. It only measures the length when
level in calm water, and does not measure the effective length when heeled and
with bow and stern wave generated. Further, even if it predicts "hull speed"
(not a fixed limit, but the speed where wave making resistance grows
dramatically), it says nothing about how effective the rig is in generating a
driving force.

Also, PHRF ratings must be taken with a grain of salt. By definition, they only
tell the performance under race conditions, and not leisurely cruising. For
instance, much of the data is from upwind sailing - certainly an important point
of sailing, but one that many cruisers will avoid, especially when carrying
guests. Also, most rating include spinnakers, sometimes large racing chutes
that you are not likely to use with an inexperience crew.

Also remember that certain configurations don't fit well in traditional
estimates. A Nonsuch 30, for instance, is the equal of many 36 foots in almost
all regards except length on deck. On the other hand, the Mac 26X may appeal to
some as a reasonable "flat water" boat is very much out of its element even in a
moderate chop (sailing, at least). (I've never seen the new Mac, but very
little this company has produced over the years has impressed me.)

Bob,

Can you give me some hints as to which popular boats have good PHRF
ratings? Also, from their specs, it seems that the C&C's have a
relatively short water-line for their length. - Does this limit the hull
speed you get from your 32?

Jim, as you can see there are a LOT of used boats around. I tend to follow
the
idea that buying a reasonably respectable brand is a good idea. Without that
you could end up stuck with her.
My favorite used boats: Pearson, C&C, Tartan, bristol, Catalina and quite a
few
more makes, models and odd designs. You need to get aboard and see what
"fits"
and what pleases your eye first and foremost. Learn to read the numbers.
Sail
area/Disp. and PHRF ratings are a good initial inidcator for how a design
will
treat you under sail. Above all, take your time. There are always
compromises,
but you can shave them down. If financial limits have you looking at lesser
boats, perhaps it's worth saving a bit longer. You never know when a magic
deal
will float along. My wife and I sold our Pearson 30 when we were married. We
were going to wait 2 or 3 years and then buy a big boat. Then I had the
chance
to buy a C&C 32 for 16K. So, while waiting for the "big" boat plan, we still
get to sail a nice boat. I think the watchword is patience. If you're in a
hurry the wrong boat may find YOU! That's happened to at least 2 people in
this
group.
