Design 1908 - Sandpiper


One of 17 boats built by Sangermani of Italy to our design over the years Sandpiper is as nicely built as the rest of them. (You can find other Sangermani boats within these pages). She was designed strictly as a roomy cruising yacht. Please note the navigator's "stateroom" aft of the nav area. And as was very common for boats being shipped to America, the lifting bridle to make putting her on a ship an easy job. She was launched in 1968 and destined for California.

Sandpiper is constructed of iroko framing and backbone and mahogany planking. Fasteners are of silicon bronze.

Here are the plans.

Sparstep 39 - Design 1693


Anyone doing business with us from overseas from about 30 years ago and farther back would recognize the name of Sparstep as our Telex address. Remember Telex? This boat has a nice shape and it can be traced back through some earlier designs such as Hestia, and even to a Pilot Class. The first one was launched in 1962. I am unclear about how many were built to this design.

The boats were built in Kong Kong by American Marine Ltd and used primarily local woods such as Yacal for longitudinal structural members and Ipol for transverse frames. They were single planked in mahogany.

Here are the plans.

Bruce McPherson - Yacht Designer


We are sad to report the passing of Bruce McPherson, a yacht designer with Sparkman & Stephens from 1965-1979 after a long illness. Bruce's primary focus was optimization of I.O.R. Ratings and producing measurement plans. I can see from our archives that over time Bruce was given more and more responsibility until he was working on complete conceptual designs.

While here in the design office he was in very good company working with Olin and Rod Stephens, Mario Tarabocchia, Harry Morgan, David Pedrick, German Frers, Jr, Gerhard Gilgenast, Gary Mull, and others.

We thought the best way to honor his memory (and his work) was to publish some of his plans. These are from design #2077, sailing yacht Arcadia, built by Palmer Johnson Yachts and launched in 1970. She is a 49' aluminum yawl designed for racing but in actuality a boat that would be a great cruising yacht. Bruce signed his drawings with a flourish using the initials: JBmCP. These are the original hand drawings and they're quite nice. Double click for bigger view.


Here is the finished boat.


Our sincere condolences go out to his family.

Design 1786- Deb (now Sunstone)


What's not to like about a bright finished boat? This particular boat was first named Deb, then renamed Sunstone and has traveled much of the globe. Her owners believe a varnished hull is actually easier to maintain than a painted hull.

She was built by McGuer of Scotland and launched in 1965 and she is in pristine condition today. She has a very respectable race record.

Here are the plans.

Even More About 25' Center Console - Design 2758


Today I flew to Maine and did further sea trails on the 25' custom center console at Brooklin Boat Yard. I have blogged about this boat before (click here to read). What do I have to say about it? Don't schedule a completion date in Maine for mid winter. There were no docks in the water at the yard so they pulled out the smallest dinghy I have ever seen to get us out to the boat. Steve White and I looked at each other and decided we displace more than this dinghy so we had a guy row us out individually with about 3" of freeboard each.

It's a really nice boat. Almost finished. And if one is looking for a similar style production boat it's actually a good value.


Steve asked about final trials and turnover to the client and I replied "Let's schedule that around when you get the docks in the water." (the windshield will be delivered in 2 weeks).

Tomorrow I am going to the Maine Boatbuilders Show. I'll get back to you.

Design 2511 - Holiday 47


This production boat was built in the Philippines in the late '80s. This was not the first S&S design built at this shipyard. They had previously built a couple of dozen 36'ers to our design. The production run for the 47' was six boats.

Here's a magazine advertisement.


And the plans.

Design 2094-C2 - Yankee 38


This production yacht is a development of Lightning, a One Ton Cup Winner, but with more of a cruising accommodations plan. Lightning was built by Minneford of aluminum. This boat is of fiberglass and was very competitive, built by Yankee Yachts of Santa Ana, California. The year was 1971.

It's a good business plan: take a proven race winner and make it available to a mass market.


Here are the plans.


Here is a peek at her underbody.

Design 1888 - Sagitta 26


This little stock fiberglass sloop was built in Denmark by Bianca Yachts. There were other Sagitta models to follow. It looks like a nice little cruising boat. The first was launched in 1967. Note the round companionway opening.

Seawind - Design 1643


This is exactly the type of boat I would be perfectly happen to own: manageable size and a nice hard dodger to get out of the rain. She would be ideal for sailing in Maine. This boat was built by R. Swanson of New South Wales, Australia and launched in 1963. It looks like she is built of all local Australian woods: spotted gum for all structural members and planked with Huon pine.

Here are the plans.

Design 2204 - Alpa 21


While this little boat looks like it might be designed as a quarter tonner, it was in fact developed as a small cruising boat. Granted it would be a little like camping out. The boats were built in fiberglass by the Alpa S. P. A. yard of Cremona, Italy, around 1975.

Design 112 - Windigo and Ptarmigan


These are two of the big yawls that were designed as ocean going cruising boats but eventually became great ocean racing yachts. These sisters were designed out of our Boston office, with Aage Nielsen as lead designer. The construction contracts went to the Quincy Adams Yacht Yard of Quincy, Massachusetts as Henry Nevins, the natural to build them, was just too busy. In the end it was a blessing due to the proximity to our Boston office and subsequent ease of oversight. The year was 1935.


They're just beautiful boats.

This one design class was developed for Indian Harbor Yacht Club of Greenwich, Connecticut in 1946 as a junior sailing class. The boats were built by Knutson of Huntington, New York. Note the early bulb keel.

Saudade - Design 2140


This aluminum yacht was built by the Huisman Shipyard of Holland and launched just prior to the 1973 Admiral's Cup. The design brief was for a boat that would qualify for the Admiral's Cup in the lower range of Class I. Further, emphasis was to be placed on the deck layout for maximum crew efficiency. In addition to these requests she was built of the finest materials and construction methods, and this helped ensure her victory for the German team.


Here are the plans.
