Design 1978 - Valiant


The following article is from Yankee magazine, circa 1971. It was written right in the middle of troubles with 12-meter Valiant.

Here's the article. That is some posed image of Olin. I'm surprised he sat for that. Please double click for zoom.


Olin readily admitted that he had relied too much on tank test data and pushed too hard to reduce wetted surface. There was clearly too little lateral area in the rudder. All I know is there are a lot of images of the quarter wave coming off the boat and various modifications tried to improve her. Take a look at the rudder profile in this sail plan.


And finally here's a look at the Valiant model in our office.

1989 - Sparkman & Stephens 60th Anniversary


Here are a couple of images from our 60th Anniversary event at Indian Harbor Yacht Club here in Greenwich, Connecticut back in 1989.

Left to right: Mitch Gibbons-Neff (President, yacht broker), Alan Gilbert (Chief Engineer), Bill Langan (Chief Designer), Thomas Watson (client and owner of the Palawans - at podium), Roderick Stephens, Jr., Olin Stephens II, Bob Sparkman (Insurance)
- Rod, Olin and Bob were retired at the time.

Design 1703 - PJ 54


The Palmer Johnson 54 was developed as a "stock" design. I believe Ashanti, shown here, was the only boat built to this design. She was constructed of aluminum and launched in 1964.


Here's an advertisement from Palmer Johnson.


Here are the plans.

From Yachting Magazine - 1931

Here's an excerpt from Yachting magazine from '31 regarding Dorade's return to America. Note the lack of aperture and propeller.

Design 185 - Souvenir


Here is another boat from the early days that has received very little notice. The boat was built by Stanley Van Sant & Son of Atlantic City, New Jersey. She was launched in 1937.

Her owner is listed as John White, Jr. of the Marlborough-Blenheim Hotel of Atlantic City.

Here are the plans. I apologize for the quality but we pulled these scans from our microfiche files.

Design 2763 - 44' LOA Sloop


Here's a 44' LOA sloop in development for a production boatbuilder.


Here are the plans. There are three interior layouts in development.

Displacement 20,985 lbs
Ballast 8,076 lbs

Design 2119 - Paxos


It's too bad we have no image of this nice looking one-tonner. Plaxos was built of wood by Cantiere Craglietto of Italy. She was launched in 1972. From the designer's comments: "Yachts to this design are building in several countries of wood, fiberglass and aluminum. To meet anticipated differing weather conditions, appropriate adjustment of ballast and sail area has been provided."

Here is the general arrangement plan.


Principal Dimensions
LOA 35'-4"
LWL 29'-0"
Beam 12'-3"
Draft 6'-5"
Displacement 14,180 lbs
Ballast 6,300 lbs

Swan 76 - Design 2331 - Sold


The Swan 76' - Wild Tigris, has been sold.

More on Design 2201 - Swan 47

A blog follower asked us if we had the layout for the Swan 47 - Mark 1 version. It's not a very good quality print but here it is nonetheless.


He also asked to have a look at her shape. Here's a peek.

Design 2069 - Queequeg


Queequeg was constructed of wood by Halvorsen, Morson & Gowland of Sydney, Australia. Her design brief was for a boat with good ocean racing characteristics and ease of handling. She was launched in 1971.

Here is the sail plan.


For whatever reason we don't have a small scale general arrangement plan handy for this design. We do have a description as follows: Aft - 2 quarter berths port & starboard, toilet room on port, galley on starboard opposite. Main cabin - dinette converts to double berth on port, pilot and transom berth to starboard. Fo'castle - pipe berths port & starboard with wash basin and marine toilet. That's easy enough to envision I suppose.


A sistership was built by W. A. Souter & Son of the Isle of Wight, England and launched in 1973, named Windliese 9. She's essentially the same boat with different woods used in her construction, increased sail plan and different window shapes. Here she is.


Principal Dimensions
LOA 46'-0"
LWL 35'-3"
Beam 13'-4"
Draft 7'-2"
Displacement 27,650 lbs
Ballast 13,000 lbs
Sail Area 895 sq ft

More on Petrel (ex-Wakiva) - Design 220


One of our designers snapped these images at Martha's Vineyard Shipyard last week. They are of Petrel (ex-Wakiva), design #220. The word on the street is that she is about to be shipped to the Pacific Northwest for restoration.

Fort Lauderdale International Boat Show 2011


The Fort Lauderdale International Boat Show is coming up fast and is being held from Thursday, October 27 - Monday, October 31. We have a limited number of tickets available, both for Thursday (prime time) and for the remainder of the show. If anyone needs tickets please email me at bjohnson@sparkmanstephens.com.

Design 283 - Avoca


Avoca is a classic S&S commuter. She is very similar to motoryacht Phoenix, design #145, but designed and built four years later. The profile of the two boats are virtually identical. Interestingly she was designed for the same client as Phoenix, a Mr. E. E. Dickinson, Jr.

Dickinson was the son of the founder of E. E. Dickinson & Company of Connecticut who produced commercially distilled witch hazel. What one does with witch hazel I can't tell you but I believe it was a remedy for a number of minor illnesses, developed by local American Indians.

The boat was built by the Herreshoff Manufacturing Company of Bristol, Rhode Island and launched in 1939. She was powered by twin Kermath Sea Raider engines developing 500 hp each for a top speed of 31 mph.

Here are a couple of early articles about the boat.


Here are the plans.


And a peek at her shape.


Principal Dimensions
