I was going to suggest a Cal
39 as well. Especially as there are some that are shallower, draft
wise. And they're reasonably quick boats. Though smaller inside than something more modern of similar length.
If you want to compare the relative speeds of boats, you can simply look at their racing
handicaps. PHRF ones are in seconds per mile, so they're easy to compare & use as a yardstick http://www.phrfne.org/page/handicapping/base_handicaps
Though to be fast from point to point, unless you're sailing a slug, the big issues are; sail choices, sail trim, & weather
routing, plus playing the currents & tide.
But rarely will a cruiser be "fast", especially once she's got all of the necessary gear
onboard. Unless, that is, you buy a racer
that's converted to cruise
, & live a more spartan lifestyle in order to keep her light.
That said, you may find this thread useful. http://www.cruisersforum.com/forums/...ce-167718.html
Especially if you follow the link that I put in there. As it leads to a question similar to yours, that I asked a while back. Which folks were kind enough to answer in detail.
Also, there are some good articles on speed, here http://www.bethandevans.com/articles.htm
Along with a (passage) speed calculator here http://www.bethandevans.com/calculators.htm
The other thing is that you probably want to spend less on the boat itself, initially. As you'll likely be spending at least half of the purchase price
of the boat on tuning up systems, & fitting her out. Though it depends on your sailing plans & goals.
It pays to make a list/spread sheet of how you want to fit out your boat, & then plug
candidate boats into it, so as to see their real cost, total. As if you need to replace some of the primary hardware
on her, like rigging
(running, standing, or both), sails
, re-do her electrical/charging system, etc. Then things add up quickly.

And if you're thinking about spending significant periods of time cruising. Such as more than a few weeks at a time. Then it's easy to spend as much tuning her up to your standards, as you spent on the boat. Often times, more. And even most relatively new boats need this kind of owner attention, as do brand new ones.
