Design 2159 - Sumbra III

Sumbra III is a very typical One-Tonner design from the period. She was built of wood using cold molded techniques by Cantiere Sangermani of Italy and launched in 1973. The design utilized the Lines, Construction and General Arrangement plans from design #2094. If you recall this was a speculative design that was used numerous times, such as the boat Lightnin', design #2094-C1.

Here is the Deck plan. The style of this drawing is interesting and was commonly done. Only the starboard sheer line is drawn since in the draftsman's mind the boat is symmetrical, so why draw it?

The ballast keel was also modified from #2094. Here's the Ballast Keel plan.

Principal Dimensions
LOA 38'-6"
LWL 28'-9"
Beam 11'-9"
Draft 6'-3"
Displacement 15,309 lbs
Ballast 8,000 lbs
Sail Area 604 sq ft

Design 2715 - 141' Trideck Motoryacht

Here's a preliminary design for a 141' trideck motoryacht. The yacht was to built with a steel hull and aluminum superstructure. Power was to be supplied by twin Caterpillar 3508B engines rated at 825hp each for a top speed of 14 knots. Range was to be 6,000 nautical miles.

Here are the plans.

A couple of points about the arrangement. Please note the owner's stateroom/suite located on the main deck forward and his private office which opens to the sea.

The actual stateroom is up a half-a-flight of stairs to bring the space up over the raised foredeck for unobstructed views through 180°.

Also note the tender garages that are accessed through the hull side, both port and starboard. This was necessitated by the lower lounge forward of the swim platform which contains some nice loose furniture, wet bar and day head.

Stylistically this boat is not my taste but was specifically what the client wished to have. I do think it had a lot of creative elements in terms of use of space.

Principal Dimensions
LOA 141'-0"
LWL 126'-4"
Beam 29'-1"
Draft 9'-0"
Displacement 848,771 lbs (half load)

Design 2413-C3 - Stevens 42

This design is a derivative of design #2413, the Stevens 40 center cockpit. She is an aft cockpit version of the 40 with new styling, interior layout and extended transom. This was commonly done to utilize an existing hull mold. The boats were built by Queen Long Marine of Taiwan. Only 5 boats were built to this design, which was introduced in 1987.

Here's an article about the boats from Yachting magazine from '87. Please double click for zoom.

And the brochure.

And finally the plans.

A peek at her interior. Queen Long builds a great production boat.

More on S&S 30

Here's the new S&S 30 with the option teak trim: eyebrow, cockpit coaming cap and toe rail. Nice.

64' Burger Flybridge Cruiser

I snapped this image of this nice looking Burger today at the Palm Beach Boat Show. The boat was originally launched as Tigertayl, in 1975. She is powered by twin Detroit 8V-71 TI marine diesels for a top speed of 17 knots. This is a variation of design #1944 (there were numerous iterations of this design).

Principal Dimensions

Palm Beach International Boat Show

Starting tomorrow, a bunch of us will be down at the Palm Beach International Boat Show, March 22 - 25. We'll be on a 55' wooden daysailer called Patrician. Find us on Ramp 2, Slip #229. We hope to see you.

Quicksilver - Design 2158

I’ve been doing some research on this boat. It looks like we used the Lines and General Arrangement from an earlier design. The plans for design #2120, Gunfleet of Hamble were used for #2158, but with a different deck geometry and layout.

Interestingly #2120 was designed for aluminum construction and this boat was designed for wood construction. The statistics look pretty identical. The only major difference is the additional sail area that Quicksilver carries, and to handle that 1,450 lbs of internal ballast was added.

Reviewing the Lines Plan it also looks like the sheer was changed forward, adding more spring. This was probably done since Quicksilver was a wedge deck and Gunfleet was not and in addition the forward sections were filled out and the Lines and Table of Offsets adjusted accordingly.

Quicksilver is an Admiral's Cup Racing yacht. She was built by Brin Wilson of New Zealand and launched in 1973.

Principal Dimensions

Design 2699 - 120' Expedition Yacht

This expedition yacht was designed with a steel hull and aluminum superstructure. Between 2004-2007 we seemed to have a whole lot of clients asking for expedition style boats. This is just one example. We have proposals between 68'-154' length overall with various deckhouse configurations.

Power was to be provided by twin Caterpillar 3412E - B rated engines producing 720 hp each for a top speed of 14 knots. The main engines were to be close coupled to mechanical, fully rotational Schottel "Z"-drive propulsion units.

Here are the plans.

Design 2207-C1 - Nauticat 521

Here we have another Nauticat motorsailer model that was based on a previous model by Nautor's Swan, design #2207. She is a heavily built motorsailer of similar proportions to the other Nauticat models. Ten boats were delivered during a production run that started in 1989 and lasted two years. The boats were built by Siltala Yachts of Finland.

Here is a design review from Sailing magazine. Please double click for zoom.

Design 2731 - Manhattan Sailing Club Dinghy Dock

If you recall, back in 2001-2002 we designed the floating clubhouse for the Manhattan Sailing Club, the Honorable William Wall, design #2686. That's her way out in the distance next to Ellis Island in the image below.

The dinghy dock was to be moored in the shallow flats behind and southwest of the Statue of Liberty. The barge was designed to accommodate 7 Lasers, 6 Sunfishes and 12 Optimists for the school's dinghy program. The boats would be stored on carpeted ramps. The floating facility's design also included toilet rooms and an observation deck. In the end the school purchased an existing barge due to cost constraints.

You can learn more about the floating clubhouse and the dinghy sailing program by visiting Manhattan Sailing Club's website by clicking here. Simply follow the links to "Clubhouse" and "Junior Sailing."
