Design 90 - 76'-6" Shoal Draft Schooner

Only two drawings were prepared for this preliminary design proposal; a Lines Plan and a Sail & Deck Plan.  I believe the Lines Plan that is shown here is the only one of the two that has survived.  That's a shame as it would have been interesting to see her rig.

I always try to do an Internet search for the old customers to see if it might have been someone famous.  The plan list gives the name William McCoy.  I was more than amused to find that William McCoy was a rum-runner during prohibition and that he ran five different schooners between Bimini and Long Island.  Could it be that the firm designed one of them?  Probably not since prohibition ended in 1933 in the United States and this design was produced in 1935. Perhaps he just wanted to spend some of his profits on a fancy new boat.  Click here to read about him.

Design 2412 - 120' LOA Pilothouse Ketch

This set of preliminary drawings for a fairly typical motorsailer was done on speculation in 1981.  I like the simplicity of the profile.  The boat was designed to be built of steel.

Here is the general arrangement plan.  There are a few interesting features such as the navigation room in the wheelhouse.

More on Design 1557 - Spirit Class

As a follow up to my posting of earlier today regarding design 1557-C3, here is Orpheus, hull number five of the series.  She was built of wood by American Marine of Hong Kong.  Her cabin trunk is specific to this hull. I think the house is very nicely proportioned.  There is 6'-1" headroom under the deckhouse. Image courtesy of Jeff Sanders and Wooden Boat magazine.

Design 1557-C3 - Spirit

We have discussed the Spirit Class before and as shown in the above image.  The boat was designed as a flush-deck one-design class for San Fransisco Bay in the mid-1960s.  Although the class never took off the original Spirit was hugely successful and various sisters were built.  It has been difficult to track what boats were built.  Here is a list of owners and boats for this design in it's various forms.

In 2000, Wooden Boat magazine published a ten page article about the boats (Wooden Boat #156).  Even here they reference the ever-allusive hull #6 as follows: A sixth boat is rumored to have been built of fiberglass in New Zealand.

I was finally able to track down this boat, also named Spirit (just to further confuse matters) and shown just above.  The boat was in fact built of fiberglass by the highly respected boatbuilder John Lidgard of Aukland in 1965.  She was built with a small, attractive deckhouse, the draft was increased to 6'-10", a separate skeg and rudder were designed and her sail area reduced slightly.  Please note that the model with the small deckhouse was dubbed the Mariner Class.

Here are a couple of shots that give a peek at her underbody and a good look at her cockpit.

Here are the Plans.

Design 1710-C23 - Sylvia II

In the past couple of weeks we have posted articles about two boats in the series of boats built to design #1710; Rumbuster and Seamróige.  While Rumbuster is a one-off, Seamróige is one of the Swan 36s.

Here we have Sylvia II.  She too is a one-off built of wood by Ateliers & Chantiers Ziegler-Frères of Dunkerque France and launched in 1965.  She is design #1710-C23.  It's a great sequence of her being loaded on a trailer.

Design 95 - Game Cock

Game Cock was designed by Nathaniel Herreshoff and built by the Herreshoff Manufacturing Company in 1925.  She is an R-Class sloop.  Her original sailplan was a Marconi rig with a headstay, but with no spreaders whatsoever and with only a single cap shroud per side, and no backstay.  The deckhouse came to a point at the front end like most all R-Class boats from Herreshoff. The rig was eventually changed to the wishbone boom configuration you see in the image above.  Both rigs proved to be a disappointment.

I can tell very little but that the firm was commissioned to redesign the rig as you see her drawn below and make modifications to the general arrangement, also shown.  I do not believe we were involved with the changes to her deckhouse geometry.  The plans, pulled here from our microfiche files, are obviously in deplorable condition.

I have no idea why this presentation plan was prepared but it conveniently shows her principal dimensions and those of the new rig.  It's curious as the files show the plan work we did was done in 1935 yet the plan below references an owner from 1944.  Perhaps that was added later as it appears to be done by a different hand.

Design 1710-C26 - Rumbuster


Last week we posted an article about hull #021 of the Swan 36 class, the beautiful s/y Seamróige. Here we have a wooden sister, Rumbuster, which is hull #026 of the entire lineup of design #1710 (this excludes the Swan 36 numbering sequence).

The owner of Rumbuster dropped us a note and included the beautiful image of her seen above, courtesy of Beken of Cowes.  The image looks like it was taken in the Solent but could not be the start of the Fastnet Race as it was not held in that year.  Nice image.  She's being pressed about as hard as she can.

Our records say Rumbuster was built by "Port Hamble" but in my mind that could mean a couple of yards in that area.  Perhaps the owner will set us straight?

Here's a copy of her original rating certificate.  I include it as it is interesting in that it shows her scantlings.

In any event she is a beautiful boat.  She makes her home near Oban on the west coast of Scotland.  The image below was taken off Eilean Dubh Mor, part of the chain known as the Inner Hebrides on the west coast of Scotland.

Update on S&S 30

We continue to receive a lot of inquiries about the S&S 30 asking about the status regarding production. We are pleased to report that the hull tooling is complete and the deck tooling is nearing completion as can be seen by the image above. We are still targeting having a boat on the water in time for the fall boat shows.

For plans, additional images, specifications and project history, please visit the Sparkman & Stephens 30 website at  Also multiple postings can be found within these pages by doing a search for S&S 30 in the search field above.

Offered at $149,000, sail away price.

Design 1767 - Aquarius 40

 Boo Hoo

We have posted about this well utilized and popular design before.  As can be found in a previous posting, various boats were built of both wood and fiberglass to this design.  For the purposes of this article let's focus on the Aquarius 40, built of fiberglass in Finland.

A writer was kind enough to send us the article found below about the design.

S&S Design #1767 - a classic yacht
Translation of an article published in the Finnish Yachting Magazine “Frisk Bris” Nr 1-2009
In the impressive list of all Sparkman & Stephens designs included in the book “The Best of the Best” Design #1767 is described briefly as follows:
Year:    1964
Client:    Various
Name/Class    Honey
Job description: R.O.R.C. aux.sloop, LOA : 39.95, DWL : 28.75, Beam : 10.04, Draft : 5.52, Type : Sloop.

R.O.R.C. means the design was adapted to the British R.O.R.C. rating rule. S&S or more specifically Olin Stephens used to analyze the rating rules for finding out what was worth doing and not doing to get a favorable rating. The other dominating rating rule at the time was the CCA rule used in the USA. The rule differences were biggest for the rigs, and therefore the rig dimensions used to be different depending on where the yacht was going to race. Also draft variations were common.

It could be mentioned that the two rating rules were soon merged into one – at an ITC meeting in London in November 1968 it was decided to replace the RORC and CCA rules with the new International Offshore Rule which contained features from both of them.

S&S had with the time built up an extensive library of completed designs which could be used as a reference for new projects, and also in this case it is obvious that an earlier design was used as a basis for #1767. In the list of S&S designs one can find #1738 having exactly the same main dimensions except for the draft which is a little more, 6.23 ft.

Because lines drawings and related calculations at the time had to be made manually it saved a lot of effort if existing information could be used with just some small modifications.

It can be pointed out that a S&S design of this age has very good performance on the wind, particularly in a blow, but does not readily surf off the wind, instead there is a tendency to rolling and broaching.

In Finland 10 yachts of GRP according to Design #1767 were built 1966…68 at a yard started up for this purpose in Hämeenlinna, and the yacht type was denoted S&S 40 by the builder.

It can be noted that this type notation already existed in the S&S list for the mentioned base Design #1738. It appears the builder’s type notation is not necessarily the same as the designer’s, and some caution is needed in this respect if only one of the notations is known. It is also possible that the as built main dimensions differ from the numbers stated in the list of designs.

The name of the new yard was Teksoglass. A company with this name already existed, but so far it had manufactured glassfiber weaves. It is likely that these weaves were used for the boatbuilding, but the yard’s history was very short, it was laid down in 1969. 3 of the yachts were sold to Finland, 5 to Sweden, and 2 to Norway.

The driving force behind this boatbuilding project was Åke Lindqvist, at the time Chief Surveyor to Lloyd’s Register in Finland. He had an active interest in offshore racing, had established contacts with S&S, and the knowledge for performing scantling calculations for the yachts. GRP was then a new and unknown material for boatbuilding, and it is likely that Lloyd’s scantling rules at the time partly built on Åke’s contributions.

An interesting detail can be mentioned here – the builders knew that air inclusions in the laminate are not acceptable, and in order to enable easy control of this transparent gelcoat was used, this made the hull translucent. The outside was then painted in a color to the owner’s choice.

The owner of the first hull was Göran Olofsson, he named his yacht BOO-HOO, Åke built the second hull for his own use and named her EVA II, and the third owner was Peter Fazer with FÅGEL BLÅ.  EVA II is nowadays in Sweden and named GRY, earlier names SCHALU and SPARK, the two others have remained in Finland. Olofsson owned BOO-HOO until 2006 when he sold her to Hans Johansson and Joakim Wilenius.

One of the Swedish yachts was named GALLANT, and she was painted light blue. The others were named GONNY, ANN-CHATRIN (later KRISTIN AF ARKÖSUND), NONCHALANT (later AXELINA), and GADFLY (later CATHENA). For the Swedish yachts the woodwork and outfitting was done by Bergviksvarvet, Bromma (near Stockholm).

The Norwegian yachts were named SIESTA and NORSEMAN, and the latter was somewhat different as she had the rudder moved aft and separated from the keel. NORSEMAN was extremely successful and won 45 prices out of 50 in IOR racing between 1967 and 1977 – an early indication of the dominating underwater concept of today. It is possible that some other of the Teksoglass-built yachts also has the modified rudder arrangement.

The Teksoglass moulds were bought in the 1970s by Turun Teräskaluste in Turku, and this manufacturer renamed the type Aquarius 40. The first hull was ready in the spring 1977. Six yachts were built, one of them has the rudder separated from the keel, and another has sailed around the world. A copy of the brochure for Aquarius 40 in German language is appended.

S&S also sold the same drawings to other clients. In Sweden Bröderna Martinsson had already 1964…1965, i.e. before Teksoglass, built 3 yachts in wood, they were named HONEY, PAVANE, and CHARLOTTA IV ( later BRILLIANT). HONEY was renamed ISADORA, and was sold to Finland, where she got back her original name. The name HONEY is mentioned in the S&S design list, and it is likely that she is the original Design #1767, although all 3 yachts were launched in May 1965, which is quite remarkable for a small boatyard.

In Denmark the Walsted yard built PAM to this design in wood 1966, she was recently bought to Finland, and has the rudder separated from the keel.

In New Zealand a wooden yacht was built 1964, she is called COTTON BLOSSOM, and is now in Ireland. Further two wooden yachts were built in Australia, one was named CORROBOREE. One was built in Hong-Kong named COLUMBINE, and two in Italy, more about them below.

S&S had a big and international clientele, and solely of this design 20 yachts were built. One wonders how Rod Stephens managed to inspect them all. He did inspection trips about once every month all over the world, and mentioned once that he had much more flight hours than aircraft captains – they have limits for this.

In the S&S list the next line after Design #1767 shows Design #1767.1, the added number means it is a slightly modified variation of the same basic design. The main dimensions are exactly the same, but the client was the Italian Navy, and the year 1965.

Two wooden yachts were built, named NAUSICA and CALYPSO. They are still in good shape, but for some reason they are not mentioned in the list of Italian Navy Sail Training vessels. This list mentions, however, two much larger two masted S&S designs, #1505 and #1505.1, length about 70 ft, and built in the beginning of the 1960s.

They deserve a short presentation.
One of them, named CORSARO II participated successfully in the Transpac Race 1961, and collected 1st price overall. She took also part in the Sydney Hobart Race 1965, both required very long sailing trips before and after the race, and this must have been remarkable experiences for officers and crew.

The other yacht is STELLA POLARE, she won the Giraglia Race in 1966, with a course record that stood 18 years. Two years later she won the Bermuda – Travemünde Race overall, this race was a predecessor to the Transatlantic.

And finally here is the construction plan for the fiberglass boats.  Sorry it's in such poor condition.

Design 1816 - Chelsea 46' Motoryacht

I happened to stumble upon this design the other day and it's one I had never seen before.  This 46' wooden raised pilothouse motoryacht was designed in 1964 for Packanack Marine Corporation of Newark, New Jersey.  Perhaps the company was named after the lake in New Jersey which bears the same name.

This little piece from Yachting magazine of 1966 shows a Chelsea Yacht and attributes it to Sparkman & Stephens but on closer inspection it does not look like the same design as shown here and I can see from the files that the 46' was the only boat designed for Packanack.

Here is the general arrangement and inboard profile.

LOA 46'-4"
LWL 42'-11"
Beam 14'-8'
Draft 3'-6"

Design 1780-C1 - Satanita

Satanita is a sister to the famous Firebrand, design #1780. She was built by Keith Atkinson of Auckland and launched in 1965. Looking at the plan list it appears the only change was the reverse transom, whereas later boats built to this design benefited from a separate rudder. The above image is a newspaper clipping, and is the only image we have of her.

It is interesting that later sisters of this design benefited form a separate skeg and rudder. The former owner of Satanita sent us the image shown below which looks to me like someone added a separate skeg and rudder, removed the old rudder, while maintaining the original keel profile.  Thanks for sending this image.

According to that owner:  When I bought Satanita there had been a crude,(in terms of design) modification whereby the rudder had been removed but the full keel profile left. A small rudder on a skeg had been fitted only a short distance from the keel. This appeared to have increased the wetted surface and the boat was totally unmanageable in reverse.

Here's a shot of the original keel and rudder configuration on Firebrand.

By following the link to the posting regarding Firebrand one can see the S&S revised keel profile, skeg and rudder at the bottom of the article (general arrangement and inboard profile for C4).

While we are on the subject of Firebrand, here's a letter we unearthed from her original owner to her then new owner describing her sailing characteristics.  It's an interesting read.  Please simply double click for zoom.

Impala - Design 1056


Our good friend Steve White of Brooklin Boat Yard was just over in Italy sailing on the beautiful classic yacht Impala, design #1056, built by A&R and launched in 1954.  The image above was taken in Porto Santo Stefano on the west coats of Italy while the image below was taken on the island of Ponza a bit further south.  Thanks Steve.
