62' Commuter - Design 2673 - Linwood II

Here's a baby sister to design #61, Linwood. Linwood was built in 1934 and built by the Consolidated Shipbuilding, at Morris Heights, New York. Our client fell in love with that design and has asked us to create a boat based on her but with a more contemporary layout. The original boat was 77' overall and our client asked us to reduce the size to 62' overall, which we have done here maintaining the aesthetics as much as possible.

Here's the layout for the original.

Schooner America - Design 1897

Built by Goudy & Stevens Shipyard of Boothbay, Maine this replica of America was built for Rudolph J. Schaefer, Jr., head of Schaefer Brewing. America was the first to win the America's Cup in 1851. This replica was launched on the 3rd of May 1967, 116 years to the day after the original was launched.

This should not be confused with the replica that was built and launched in San Diego in 1995.

Yankee - Design 1278

If there ever was a design that can be described as having a colorful and famous history it is Yankee. Designed for world-wide cruising, but in particular cruising the canal systems of Europe, she is the subject of numerous books, articles and videos.

Sail Plan

Built for Irving Johnson, a retired professional sailor, the boat was built of Corten steel for strength and twin centerboards for shallow draft and was specifically designed to allow the owner to "beach" the boat without injury to her. With the masts stepped on deck an ingenious tabernacle system allows the owner to single-handedly raise and lower the sailplan himself. At least 8 boats were built to this design.

Atlantique 50 - Design 2667

Pursuant to my posting of yesterday regarding the Passagemaker 60, here's a bit of background about the design. This is the Atlantique 50, a smaller version of the boat. The genesis of this project is interesting. The concept was the brainchild of one Vincent Maussett. Vincent can be described as the consummate tinkerer. Race cars, furniture, boats you name it; he's always thinking and sketching. Here's a race car he designed and built in the '70s.

Vincent came to us and asked us to take his sketches for this design and turn them into reality. Extensive design followed including a tank testing program.

Only 1 boat was built to this design. It was felt the 50' size was too limiting in terms of the interior. This boat is a 2 stateroom boat. It was decided to redesign the boat at 60', adding a third stateroom. In addition, the integral swim platform was added to the 60' version, increasing waterline length and prevention squatting which a canoe stern boat tends to do when pushed above displacement speed.

The company that built the boat was ultimately sold to Sea Spirit Yachts who has now developed a series of Passagemakers. In addition to the 60', the 50' design (now 51') has been retained for those looking for a smaller Passagemaker but the integral swim platform has been adopted for improved performance. Additional models include 55', 75' and 88' versions.

Design 1609 - Personnel Carrier

This personnel carrier named Lumba Lumba was designed for Caltex, a major petroleum company and launched in 1960. Constructed of aluminum by Paasch Marine in Erie, Pennsylvania, she was designed to carry 30 passengers in aircraft style seating plus 4 officers and 6 in crew. The officers had permanent quarters on-board in 2 cabins with lavatories while the crew cabins consisted of pipe cots and a shared head.

Incidentally, at some point there was a radio controlled model kit sold of this design. We have had an unusually large number of inquiries in recent days from people interested in building or restoring radio controlled models of this vessel.

Here are the plans.

Passagemaker 60 - Design 2719

Here's a production motoryacht that is built in China of composites. That's our Fort Lauderdale broker Jack Zacks at the helm in the image above who is very knowledgeable about these boats. It's a single screw full displacement boat and built to a high level of finish. 3 boats have been launched and 2 more are under construction. The first 3 boats were painted dark blue. Here's the color scheme for the 4th boat which is about to launch. There are so many boats being painted dark blue these days that this is a refreshing alternative.

Here are a few interior shots, all by photographer Neil Rabinowitz.

12-Meter Vim - Design 279

Images Courtesy of Beken of Cowes

This was the first 12-meter designed by the firm. The owner was Harold S. Vanderbilt, who had previously campaigned the J-Boat Ranger in 1937. The boat was shipped to England in 1939 and raced successfully winning 19 out of 28 races that year but World War II was to postpone any America's Cup racing. The twelves would only resume their America's Cup competition in 1958. By that time changes in the 12-meter rule would make her obsolete. She's still a beautiful boat.

Here are the plans.

The boat was extensively tank tested during the design process. In addition, the boat had a few innovative details such as a trim tab integral to her rudder, 2-speed winches and was the first 12-meter with an aluminum mast. The trim tab can be see in the rudder detail drawing below (click for larger image). The control mechanism for the tab was internal making a locally hollow rudder necessary.

The boat was completely restored in 2003 and is currently for sale.

101' Classic Sloop - Design 2737

This classic sloop is currently in design. The owner spent many years chartering one of our older designs so this design is loosely based on the aesthetics of that great old boat but in a smaller package. The flow between indoor and outdoor social spaces is of primary importance.

Gemini 52' - Design 2650

This modern looking production boat was built by Gemini Yachts of Padova Italy, now defunct. The styling and interior were designed by Nuvolari Lenard. This is definitely what we would call a "med" style boat. 3 boats were built to this design. It was not a bad boat and a shame the builder went out of business.

3-Masted Bark - Design 2334

Rod Stephens was incredibly involved with the S.E.A. (Sea Education Association) program. He provided technical expertise to one of their existing fleet, the tall ship Corwith Cramer. This knowledge and enthusiasm for the type led to the design of the 3-masted bark you see here. Unfortunately, the boat was never built but the design is interesting nonetheless. I think it's a fine looking vessel.

195' Aluminum Motoryacht - Design 2688

La Baronessa

This 195' aluminum displacement motoryacht was launched by Palmer Johnson in 1999. The styling and interior design was developed by the design firm Nuvolari Lenard of Italy. Naval architecture and structural engineering was by Sparkman & Stephens. The boat is unusual as she is all aluminum, where most yachts of this class are of steel or built with a steel hull and an aluminum superstructure. The boat was extensively tank tested including different sea states and at anchor to optimize running gear and appendages to minimize roll.

She's a behemoth. The boat displaces 1,536,000 lbs when fully laden. By comparison the maximum take-off weight of a Boeing 747 is 735,000 lbs.

The boat is powered by twin Caterpillar 5212B diesel engines developing 1,950hp each driving controllable pitch propellers. Top speed is 17 knots. The boat carries an astounding 42,000 gallons of fuel which equates to a range of 14,000 nautical miles at an endurance speed of 10.5 knots. Just to put things into perspective, a typical large tanker truck as seen on U.S. roads carries 9,000 gallons. That's almost 5 trucks showing up at the dock for a refueling.

The boat has a creative split level design. The interior is finished in glossy ebony and lacewood.

Design 2652 - Nighthawk - 55' Motoryacht

Launched in 1999 by Lyman Morse Boatbuilders, this design combines the salty aesthetics of commercial vessels of both the Pacific Northwest and New England for a very distinctive looking yacht meant to go to sea. A pair of 660hp Caterpillar engines drive the deep V hull at a cruise speed of 18 knots and a maximum speed of 22 knots. With 1,000 gallons of fuel, a range of 1,000 nautical miles is achieved at 10 knots with 10% reserves. The propellers are located in deep tunnels for reduced draft.

The interior layout is spacious and features a large pilothouse. In addition to the helm station, the pilothouse has a comfortable sitting and dining area and a navigation/office area. The main salon is combined with an open, well-equipped galley, separated by a counter. At the aft end of the salon, a large door allows the living space to be extended into the aft cockpit.

The owners, realizing they would seldom require three staterooms as typically found in boats of this size, opted for accommodations for four in two generous staterooms, each with their own private head. With long cruises in mind, opposite the guest cabin is a utility room that contains a washer, dryer, ice-maker, workbench and tools. The workbench converts into a spare berth for use by crew when needed.

Mathis 31 Sportfish - Design 1595

This design is a bit of a mystery. The technical files show a project name of Mathis 31'. Mathis was historically a boat builder in Camden, New Jersey which eventually became Trumpy Yachts. Yet Mathis ceased building boats in the mid 1950s and the date of this design is 1961.

The boat was extensively tank tested at the Davidson Laboratory at Stevens Institute of New Jersey. Here's an image of the tank testing in progress with the boat at 20.2 knots.

Nortada - 43' Power Cruiser - Design 14

This appears to be the first Sparkman & Stephens powerboat launched (although design #3 was a powerboat design, it was not built). The year was 1931. She was heavily built by one William Bunce of Huntington, Long Island. She was powered by twin 4 cylinder engines of 56hp each for a cruising speed of 10 knots.

The general arrangement looks quite practical for a 43' boat with a cabin including en-suite head on each end of the boat separated by the engine room/wheelhouse for reasonable privacy for two couples.

The hull lines look definitively influenced by sailing yacht design. There was 5,000 lbs of ballast integral to the skeg.
