Design 309 - 53' Fishing Cruiser


This handsome looking motoryacht named Timber Doodle was built in 1940. For a design firm that is best known for sailing yachts, the more I look through the files the more motoryachts I find. Built of wood by Consolidated Shipyard, she was designed for staying aboard for lengthy periods of time. Emphasis was placed on being a very comfortable sea boat.

Design 2608 - Ocean Going Tug Conversion


Itasca is an 175' ocean going tugboat that was converted to a yacht. Purchased by former Secretary of the Treasury William E. Simon, she was purchased with the intent to convert her to a yacht and attempt the Northwest Passage. Here is a profile comparison between her original configuration and her transformation into a yacht.


And finally here's a nice shot during transit of the Northwest Passage. In 1994, she was the first recorded yacht to make an eastbound transit successfully, completing the trip in 23 days.

Alternate Wood Choice - Butternut

Main Salon Blackwatch (ex-Edlu II, ex-Tabor Boy), Design 218

Butternut (juglans cinerea), is actually a nickname for white walnut, a member of the black walnut (juglans nigra) family. It's a great wood for boat joinery as it is very stable and resists cracking. In addition it's beautiful with rich grains of honey with red highlights. It's also a fairly easy wood to work with and more affordable than alternate woods.

Someone sent me the above photograph. I can tell immediately that it was taken by either Billy Black or Onne van der Wal, as it is clearly a professional shot: lights on, table set, flowers on the table, cloudy day outside...so whoever took this shot I apologize, but nice photo.

Norwalk Yacht Club Launch - Design 1521


For those of you familiar with the club launch at the Norwalk (CT) Yacht Club you will be pleased to know she was designed by Sparkman & Stephens and launched in 1961, named Greens Ledge. The fiberglass launch was built by the Jakobson Shipyard in Oyster Bay, Long Island.

Here we are performing an inclining test the boat for the US Coast Guard certification for carrying passengers.

TS 163' - Design 2555


Here's a project that never got any traction but is interesting none-the-less. It is a design proposal for a high speed motoryacht with an overall length of 163'. Labeled the TS 163', it brought together a talented team of builder, designers and engineers:

Shipyard: Tecnomarine of Italy
Exterior Stylist: Design Studio Spadolini (Tommaso Spadolini)
Interior Design: Paola D. Smith
Naval Architecture & Engineering: Sparkman & Stephens

The T in the model name refers to Technomarine (not to be confused with the watchmaker) and the S refers to the three S's: Sparkman & Stephens, Paola Smith and Tommaso Spadolini.

General Arrangement Plan

Principal Characteristics
LOA 163.0'
LWL 129.6'
Beam 33.5'
Draft 4.92'

Power
CODOG propulsion with twin GE LM1600 gas turbines developing 17,600 hp each and twin Deutz TBD 604B V16 diesel engines coupled by way of a MAAG combining marine reverse gears coupled to steerable RIVA CALZONI water jets.

Performance
Continuous max speed with gas turbines 70 knots
Continuous max speed with diesels 17 knots
Endurance speed (for max range) 10 knots

Range
At max speed with gas turbines 500 nautical miles
At endurance range speed 3,000 nautical miles

Design 1740 - Double Eagle


Here's an interesting design shrouded in secrecy. From the files I can see the client is listed as the "sponsor" but that only leads me to believe it was the U.S. Navy. The design brief was for a 79' high speed "crew" boat utilizing twin diesel engines for cruise speed and twin gas turbines turning super cavitating props for boost speed of over 50 knots in sea state 3.

Outboard Profile Drawing

The boat was built by General Dynamics of aluminum. The year was 1966, pretty early for a gas turbine powered boat and I would not be surprised if it was not the earliest.

Here's a construction sequence.


Here's the boat at speed. The boat achieved 57 knots during sea trials.



A detail shot of the bridge.

Cockpit

Note the small segmented windshield. In reviewing the engineering report it was felt that windows of this (small) size were needed to withstand wave impact at speed.


"Crew" Seating

Here's a shot of the out drives. The outboard drives are very early Schottel drives. We're using Schottel drives on a boat we are building now. You can see the super cavitating props on the inner shafts.

Modifications to a Swan 47 - Design 2201

Here's a pretty typical major modification to some of our older boats: remove the bustle and skeg, re-fair and install a carbon spade rudder plus install a carbon mast and boom. This project was done to a Swan 47.

Here's a sketch of the proposed changes.

Here's a sequence of images which depict the changes.

170' Ketch Nazenin V - A Matter of Scale

The construction of a 170' aluminum yacht is something most of us don't come across every day. I thought it might be interesting to illustrate a few steps along the way.

Here's a full scale section of the boat that was constructed by RMK prior to beginning in earnest. This was so that all parties would be satisfied with the construction method: we (the architects), the builders and the classification society, ABS (American Bureau of Shipping) who inspected and certified the construction.

Interior drawings were prepared by the interior designers, Redmond, Whiteley and Dixon. These were translated into artist renderings so the owner could envision the yacht and ultimately full scale samples were built for approval. Here's a typical rendering.

And here's a joinery sample built by the shipyard.

Finally the keel is laid.

Fast forwarding, the boat begins to take shape.

The boat was built upside down to a point and along the way the boat had to be righted. This required four massive cranes. If you notice the men in the image it puts things into perspective - she's big.

Finally a special cradle had to be designed and built to properly support the boat during launch. Launch condition weight was in the neighborhood of 750,000 lbs. They're the same principles we follow with any boat, it's just a matter of scale.

And she's launched.

Design 2707 - Fairweather


This 52' classic looking sloop was built by Lyman Morse Boatbuilders and launched in 2004. She is a semi-custom composite boat (the molds exist for future builds). The styling of the deckhouse on Seguin 52 #1 draws its inspiration from Sparkman & Stephens’ famous design BOLERO built in 1949, one of the owner's favorite yachts.

This particular boat is highly customized in terms of joinery details as can be seen in the images. Thanks to Bill Black, photographer, for such a nice set of images.

The boat is currently on the market. Please feel free to contact us for plans, specifications and pricing.
