Sailboat characteristics

Below is some analysis of the Crealock 34 and Crealock 37 vs. various "ideal" designs.  It is based on the excellent database and spreadsheet that I downloaded from John Holtrop's www.johnsboatstuff.com circa 2000.  (the download link is towards the bottom of that page)  Here is an article from Cruising World, April 1998.  The quotes in the lower right corners of the graphs below were mainly from Holtrop's spreadsheets.  The other annotations on the graphs were from various sources (any errors are no doubt mine).

I am starting to work on an interactive version of the plots below.  It should be found here.  It is still a work in progress, so please give it a try and come back to it from time to time.  I hope to continue to enhance it.

The worst conditions I've been in was a crossing from Key West to Isla Mujeres.  It was the wrong time of year to be out there (January).  I was about half way across when I got plastered by a 45 knot gale.  After a while I hove to and basically passed out from exhaustion.  I thought Breakaway handled it very well though.  The next morning the waves were up to the spreaders (I'm guessing 35').  A Coast Guard Search & Rescue plane flew over (I thought it was going to hit the mast) and I contacted them on the radio.  They asked if I was boat such-and-such.  It had declared a Mayday and they were out searching for it.
 
Sometimes I wish I had gotten the Crealock 37.  It would have meant more space - a couple inches here and there would make a big difference down below.  Also there would be more space for spares and stores and such.  Plus a 37 would have been a little faster (0.2 knot based on their PHRFs) and likely have a little gentler motion.  Still, Breakaway will be a little cheaper to maintain (hauling and slip costs for a 37 would be only slightly higher - 10%; but other costs like bottom paint, new sails, rigging, etc probably go up with the displacement - roughly 25%).  Also, Breakaway is probably a little easier to manage - consider windage when hauling in the anchor in some wind, the weight of the chain+anchor and being able to pull up an all-chain rode from any depth (say, by hand quickly when you are single-handing and in a tight spot), setting/retrieving a sea anchor or drogue, docking, etc.

I just watched a larger sailboat come into the harbour and circle around 3 different moorings.  They hit ground at each and ended up tying up to the dock at the marina.  This reminds me of another desireable characteristic typical of a smaller boat - a shallower draft.  Breakaway has the shoal-draft keel option (called the Scheel Keel).  So she draws about 4'.  The Crealock 37 with a Scheel Keel draws 5'.  I know a foot difference doesn't sound like much but it really does help.  E.g. "going over the bar" in Livingston, Guatemala was very easy with a 4' draft.  5' meant being careful of the tides.  6' or more was tough.

You spend a lot of time in the cockpit - either at anchor or under way.  Another thing about the Crealocks that I really like is the cockpit - with nicely rounded, large corners to curl up into.  Also, the combings are well rounded so it's not too bad when you knock into them or brace against them when the boat is in motion.  One possible negative is that the locker clasps stick out.  Somebody who was crewing on a Crealock 34 with a tiller arrangement was saying that he found himself hitting the clasps quite a bit when moving around the cockpit.  This is not a problem with a wheel steering configuration as the wheel pedestal prevents you from getting too close to the hasps.  The tiller arrangement does make for a nice large open cockpit in port, and is obviously preferable by some for the feel of the rudder when underway.
 
I think the size of Breakaway's cockpit is just right.  The seats are just long enough to sleep on.  I "catnap" on overnight passages - sleeping for 15 minutes at a time.  Sleeping in the cockpit is easier than going up and down to a berth below every 15 minutes.  I've read that you don't want the cockpit too large on a bluewater boat in case a wave fills the cockpit.  I've only had a couple small waves break into the cockpit - in a spot off the Yucatan Peninsula where the strong Yucatan Current and I believe a counter current meet and create strange wave conditions.  The large scuppers seemed to drain the cockpit quickly.  In each case, it was while I was asleep so kind of a rude awakening having a wave dumped on you out of nowhere :-).  Breakaway's cockpit is IMO large enough to entertain comfortably at anchor or on an easy day sail.   
The figure lying in the cockpit is scaled
to 6' tall. You need to try it yourself, of
course, to see if it fits for you.

Make sure, if you are shopping for boats, that there are good handholds in the cockpit to grab onto when the boat is in motion.  The U-shaped pipe over the steering pedestal is my main handhold in the cockpit.  And the support for the hardtop bimini is a little beefier than normal (1" s/s tubing supporting the front with 2¼" aluminum pipe for the aft "goalpost" support) that I can brace against it with a secure feeling.  Also, see if you can brace comfortably at the front side of the steering pedestal - standing in the cockpit with your rump against it, looking forward.  You spend a lot of time in the cockpit.  It should be comfortable and functional.

With this being the week of Darwin's 200th birthday, there have been quite a few articles on the web regarding Darwin and evolution.  Here is an interesting paper on the effects of evolution on the design of Polynesian canoes.  It includes this cool quote translated from a paper written in 1908:
 
  Every boat is copied from another boat... Let's reason as follows in the manner of Darwin. It is clear that a very badly made boat will end up at the bottom after one or two voyages, and thus never be copied... One could then say, with complete rigor, that it is the sea herself who fashions the boats, choosing those which function and destroying the others.
 
FYI, here is some background on the paper.  The paper is actually trying to sort out the nature of cultural change.  Polynesian canoe design is just the guinea pig. 
 
One of the characteristics that I really like about Breakaway is the canoe stern.  Whenever I have her hauled out of the water, when she is in the slings of the travel lift or resting in the jackstands, I find myself occassionally gliding my hand over the contours of her rump.  It just looks and feels so nice.  I've read peoples' opinions that a canoe stern tends to behave better in a following sea (where the waves are overtaking the boat from astern) - parting the waves more easily and not letting the boat get pushed about as might occur with a flat transom.  Following seas still make me nervous, but Breakaway always seems to handle them well.  I have read that the double ended, canoe stern is based on the designs of Colin Archer and the original Norwegian lifeboats.  Probably pretty good genes.

  The US Sailing page on PHRF says:
 
                                 A
    Correction Factor(TCF) = ----------
                              B + PHRF

The denominator, B + PHRF, is the number of seconds it takes to sail a nautical mile in the expected conditions. Another way to look at it is that the denominator divided into 3600 is the average boat speed in knots. Here are some commonly used B factors:

B FactorWhen Used
480 Heavy Air or all off the wind
550 Average conditions
600 Light air or all windward work

Then, using handicaps from PHRF New England (17 May 2010) I'd calculate average boat speeds as follows:
Boat HandicapAverage boat speed (knots)
Heavy Air or
all off the wind
Average conditionsLight air or
all windward work
Crealock 34201 5.34.84.5
Crealock 37174 5.55.04.7
J/105 81 / 90
(spin/non-spin)
6.4 / 6.35.7 / 5.65.3 / 5.2

At the bottom of this page are some plots of LWL vs average boat speeds as calculated above based on PHRF ratings for the Crealock 34 and 37 vs a large number of boats in John Holtrop's database (downloaded 16 Aug 2010).  The 3 charts show the results for heavy, average, and light conditions.  I've plotted the J/105 for comparison.

I'm in the process of repowering Breakaway and have put some notes regarding that here.
