Design 1540 - Sapphire


The more we look into the files the more boats we find that were built in New Zealand and Australia. This attractive sloop was built of wood by P. Vos, Ltd of Auckland. She was launched in 1960.

Here is the general arrangement plan.


This article, while lengthy, tells the story a lot better than I can. It's on three pages. Double click for readable view.


Principle Dimensions
LOA 42'-0"
LWL 27'-6"
Beam 8'11"
Draft 6'-0"
Displacement 17,344 lbs

Design 2502 - 88' Sport Fisherman


This is a preliminary design that never came to fruition. Okay, not the prettiest boat I've ever seen. I'm just reporting the information. The year was 1985.

Here's the layout.

Design 2090 - DM22 Quarter Tonner


Commissioned by Douglass & McLeod, this quarter tonner is somewhat unusual, but innovative. At first blush I suspected that they were using an existing hull mold and making changes to the sheer by adding to the deck tool. See close up below.


You can see how much freeboard was added to the height of the reverse sheer. After reviewing the technical files this is in fact a brand new hull design.

The innovations didn't stop there. Check out the keel design in the plans, below.


Here are some "Designers Comments" from the time of launch: This compact and versatile little MORC cruiser offers a logical forward step for many small boat sailors. Her removable rudder, her retractable keel, hinged mast and outboard engine tend to improve her trailer-ability. She has been designed to the Quarter Ton Rule and can be trailered to events and kept-economically-at home. Her accommodations afford generous sitting headroom.

Principal Dimensions
LOA 22'-0"
LWL 18'-9"
Beam 8'-5"
Draft 2'-9" (board up) 5'-3" (board down)
Displacement 3,500 lbs

I think the Lines Plan is worth a look. If you look at the design without the deck add-on to the freeboard it would make a handsome looking boat. No offense intended to those that own these!

Design 1282 - Whisper V


Unfortunately we don't have any images of this beautiful yawl that was built by the famed Cantiere Sangermani of Italy and launched in 1959. As I mentioned in a previous post 17 boats were built by this yard to the designs of Sparkman & Stephens.

Here is the general arrangement plan.

Design 882 - Florita


Here's one of those little gems we come across from time to time in the files. She is a 26.5' powerboat that was built of wood by the Essex Boat Works, of Essex Connecticut and launched in 1950.

She is built of white oak for structural members and planked in mahogany. Power is from a single Chrysler 100 hp gas engine for a top speed of 13.5 knots at 2,000 rpm.

Here are the plans.

Design 1557 - Spirit Class


This lovely little flush deck racing yacht was designed for racing on San Fransisco Bay. She was designed as a prototype for a potential one-design class of boats. She was built of wood by American Marine Ltd of Hong Kong and launched in 1965.

Here is the general arrangement plan.


It looks like a great boat. I like the cockpit so far forward (and generous) and the sliding hatches into the accommodation space and into the lazarette.

Here's an article with some additional details. Double click for bigger view.


A number of these boats were built around the world. As a further development, plans were created for a cruising version with a small deckhouse, nicknamed Orpheus. Plans as follows.


Principal Dimensions
LOA 33'-5"
LWL 28'-6"
Beam 8'-5"
Draft 6'-3"
Displacement 12,320 lbs
Sail Area 613 sq ft

Design 2234 - Mania Two


As a follow up to my previous post this 92' aluminum motoryacht was constructed by Stephens Marine of California and launched in 1976. Our files say it was designed for "a prominent European yachtsman" and with a little snooping around I can see the client was one Nicholas Goulandris. I believe he was an important collector of ancient Greek art, and his collection is in a museum in Athens bearing his name.

It's an interesting boat and is described as a fishing yacht. Most notable is a centerline inboard - outboard that was used in trolling mode only. She was otherwise powered by twin MTU 12V331 TC71-12 cylinder diesels generating 1,100 hp each and turning 46" diameter 4-bladed propellers for a top speed of 21 knots.

Here is the general arrangement plan.


Principal dimensions are as listed in my previous post.

Design 2375 - 92' Motoryacht


This preliminary design was never built but I thought it an interesting profile study so we are publishing it here. It is based on an earlier design, Mania Two (design #2234) which we will post about shortly. She was to be built of aluminum. Target top speed was to be 18 knots.

Principal Dimensions
LOA 92'-0"

Installed power is twin G.M. 8V71 diesels generating 268hp each for a maximum speed of 15 knots. She is designed to carry 224 passengers.

Here are the plans.

Avanti - Design 85


Designed for Walter Rothschild and launched in 1937, Avanti was one of very few Sparkman & Stephens designed built by the Herreshoff Manufacturing Company of Bristol, Rhode Island. Walter Rothschild was the great-grandson of a founder of Abraham & Straus, Abraham Abraham, and was the fourth generation of his family to serve as the company's president.

Avanti was the next in a progression of earlier designs including Dorade (design #7), Stormy Weather (design #27), Edlu I (design#35) and Santana (design #59).

Here are the plans.


Unfortunately, she was destroyed in Padanaram Harbor in the hurricane of 1954. Click here for related posting.

Here's an article from Wooden Boat magazine showing Avanti under sail and on the beach after the hurricane. Double click for readable view.

Design 1449 - Sea Star


This big motorsailer of 90' length overall was built by the Burger Boat Company of Manitowoc, Wisconsin and launched in 1959. She is constructed of welded steel with teak decks and deckhouse.

Here are a few deck shots.


What can I say about the cheesy bikini clad model? They're the images we have on file.

Here are the plans.


The large cockpit was converted to an all-weather wheelhouse in 1966.

And some interior images.


The last I saw of this boat she was in Miami in very rough shape and with a broken main mast. I spoke with a gentleman since who is a boatbuilder from Holland. He told me he had purchased her and had her shipped to his yard in Holland for a complete restoration.
