OK, here is the C&C 61, including an ad, for a bit of color. The C&C 61 was probably a crowning design for C&C. Big, very fast, and given the big foretriangle, a bear to sail. The one here was named Sorcery, had a good race record, and was rolled over in the Pacific en route from Japan to the US. Made for an epic sea story.

Anyone looking for other designers? Post a request, there a many more.

Will be posting Charley Morgan's noted design Paper Tiger soon.

Lydia, that is a neat boat! Is it yours?

Here is one of my favorites. It is not a sailboat; powered by some unknown type of fictional electric propulsion. Of course, if I could afford one of these, I'd have it powered with a small reactor, maybe surplus from USS Jimmy Carter.

The designer of this vessel is Harper Goff. He passed away many years ago, but if Disney ever does a re-make, they had better stick with the Steampunk Goth design theme.

Fun times....let's go sink a few warships.....just watch out for the giant squid.

Love this thread and hope to keep it going.  Like SJB I have a library of these design clippings from about '68 thru '80.  Given the heavy C&C theme here, I thought I'd post one of my favorites, Bonaventure V, having logged over a thousand racing miles on her.  Anyone know her current status?  The drawings here show her initial configuration, and in spite of what the article says, the design was still pretty heavily CCA-influenced.  Sometime around '74, she came back into the shop for a new keel, a bum-tuck and some collagen injections for a more modern look.

would anybody know why they had those extremely swept-back-leading-edge keels & now not any more?

Norfolk. The original one
Tradition, fashion and  hydrodynamics, Most of those boats were designed before there were the results of computers / hydrodynamic flow computation/ and testing. The designers were following on from long keeled boats, but with a fin, so a cutaway forward resulting in that swept back look.

More recently the results of all the tests and computations have shown better performance of a fin keel, with a more vertical look. IIRC the latest thinking  is for the leading edge for most cruising boats should be around 17 degrees of  sweep back and the aft end near vertical.

The faster the boat the more vertical the leading edge, hence very little sweep back if any on foilers.

Expect fashion following designers, to start adding all sorts of foils to boats that don't need it, like the fashion for winged keels a few years ago..

I think that is a pretty good answer.  Computational Fluid Dynamics  were not available to designers in those days, and tank testing was/is very poor for evaluating keel performance because of the scale effects.  There was a whole generation of boats in the mid '70s that got shallow draft keels because tank testing suggested that the performance loss was less than the rating reduction (it wasn't).  There is another reason that keels are more vertical now and that is that if you want to maximize stability and minimize wetted surface, you will wind up with very little taper and very little sweep.  No surprise that Bonny's new keel was more upright.  The other change that was made was to a different foil section with a narrower drag bucket to gain some upwind performance at the expense of some speed on the reaches.  It seemed to work, but she was still pretty darned fast on a reach.

Wow! I was always curious about the 36R - never saw one in the flesh.  There was a half-hull model hanging in the design office and the standing joke was that there were more hull models around than actual boats.  I guess that was probably true and that the model was not a commercial success, but it looks like a neat boat though.  The business model at the time was to have a series of stock hulls that an owner could customize to a significant degree.  It seemed to work for the 43, 50 and 61, all of which have been featured above. I think the 36R was intended to extend that range downward a bit, but there didn't seem to be a lot of takers.  Since we are on the subject, the 50 was more or less replaced by the 48 which proved to be a bit of an embarrassment for the reason that I cited above - poor performance due to insufficient draft.  And, speaking of keels, Bonny wasn't the only "classic" C&C design to get a new keel, I did one for a 50 as well that was a cast iron carrier with a lead bulb (the owner owned an iron foundry).  I think it helped, but it's always hard to tell for sure.

Just found this post after a friend mentioned it to me. I own a Gurney Hotfoot, I would be interested in finding other owners if there are any other boats still around

The site seems be a bit resistant to uploading drawings & pictures; hoping this works. It should be the sail plan for PAPER TIGER, Charley Morgan's first real effort. She won the SORC back to back in 1961 & '62.

And here are the 1969 Canada's Cup boats, Manitou and Niagara (from S&). These were published in the design section together, October 1969.Manitou is in the UK; Niagara has disappeared from history, last reported in Florida. These 2 boats were a leap in to the future with racing vs cruising features, but were very heavy vessels.

A little more Manitou nostalgia. I sailed on her in the 1980s when she was raced in the UK.
