Calculations

Hull Speed
8.1 kn
Classic: 7.87 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

8.11 knots
Classic formula: 7.87 knots
Sail Area/Displacement
14.7
<16: under powered

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
14.65
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
34.5
<40: less stiff, less powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

34.48
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
314.9
275-350: heavy

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
314.88
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
41.2
40-50: heavy bluewater boat

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
41.18
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.7
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.67
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

The Baba 40, also known as the Panda 40 and later the Tashiba 40, is the third of the Baba lineup of boats involving developer Bob Berg, designer Bob Perry, and the Ta Shing boatyard. One can arguably consider the Baba 40 a full keel reincarnation of the Valiant 40, the boat that put the word “performance” next to “cruiser”. Knowing that I guess it’s not so surprising to find the Baba 40 inherits a good turn of speed – owners even trumpet around-the-buoys racing victories in these serious blue water cruisers. They are beautifully balanced with a wonderful feel at the helm, and what’s more, they have some of the best interiors to be seen in production cruising yachts.

History

The story of the Baba 40 really starts with the Baba 30 which brought together a winning combination of talents – developer Bob Berg, designer Bob Perry, and what was then a little known Taiwanese boatyard called Shing Sheng. Through the success of the little Baba 30 and the Baba 35, Shing Sheng started on the road to become a force in the boatbuilding world. By 1979 they had changed their name to Ta Shing and had moved to a new purpose built factory. It was in this year that Berg commissioned Perry to design a new 40-foot model to fill out the line.

Perry was not happy with merely evolving his earlier Baba 35 design, which in itself was a stretched version of the 30. Instead, in search of more boat speed, Perry dusted off the lines of his famous Valiant 40 with its radical fin keel and separate skeg-hung rudder had defined the “performance cruiser” category only five years earlier. From the Valiant 40 hull form he derived an all-new full keel design which was to be the Baba 40. It proved to be a huge step forward over earlier Babas with Perry describing the Baba 40 having an entirely different stability personality. It was stiffer initially, beautifully balanced and much faster.

Tim Ellis who oversaw construction fondly remembers the symbiotic partnering of Berg’s development and management, Perry’s design, and Ta Shing’s undisputed capabilities as builder. He recalls the exacting attention fostered by Berg.

“They produced a design of sublime artistry. I think it is no exaggeration to suggest that Bob Berg made at least thirty or more visits to Taiwan during the years Baba designs were under development and construction, and he and I would sit on each yacht for hours, days and more to fine tune shapes, appearances, major and minor details, and resolve the niggling issues that plagued others less well traveled. My job was to take Bob’s advice and adjustments and translate them into action. My list of items might run into the hundreds during each visit, and many, many more on a hull number one. In pursuit of his ideal, Bob left no room for equivocation, and a lesser builder would have baulked.” – Tim Ellis

The Baba 40 was introduced to the public in 1980. In 1983, when Berg left his association with the Flying Dutchman dealership who owned the Baba trademark, he marketed the boat as the Panda 40. This name did not last long and by 1984, with Ta Shing now a contender in Taiwanese boat-building, marketed the boat by themselves using the name Tashiba 40. It’s been speculated this was a play on the words names “Ta Shing” and “Baba”.

Production ended in 1996 with a total of 115 boats being built, although hull numbers can be found that run up to #182, there is a gap between #33 and #101.

Ta Shing eventually formed an exclusive relationship with the Californian based company PAEI who had Al Mason as their in-house designer. Sadly, years later when PAEI shifted focus to power boats, many of Ta Shing’s molds including the Baba 40 were cut up.

Configuration

The lines of the Baba 40 follows its ancestry back to traditional Scandinavian double-enders. Under the waterline is a full keel with a cutaway forefoot and as with many of the Perry full keel designs, the keel meets the bilge of the hull without the traditional “wine glass” section blend. Both features reduce wetted area. The hull shape is relatively beamy offering good interior volume. A cutter rig plus bowsprit combo is employed on most boats though it is believed two boats were optionally built as ketches. Another major variation was a pilothouse model with its two comfortable staterooms; about eleven pilothouses were built.

Interior

Belowdecks the quality of workmanship is superb, many Taiwanese man-hours were used in detailing the interiors with the close guidance of Berg who was known for his ability to squeeze function into every square inch of a boat. Perry also considered it one of his best, noting that it feels “right” with near perfect detailing and a layout with no apparent compromise.

On the starboard quarter, there’s a cabin with a double seagoing quarter-berth. To port there’s a well laid out U-shaped galley. In the saloon, a two-settee berth layout with pilot berth to port was offered as an option to provide extra sea-going berths. In the forward cabin, there’s a double berth offset to port. Headroom is a generous 6′ 5″.

The Tashiba 40 boats had less detailing which has been attributed cost cutting measures by Ta Shing – less teak trim, less portlights, and gone are the butterfly hatches in the Baba 40.

Construction

The Baba 40 hull is solidly built in hand-laid GRP, with hull thickness growing from 0.41″ thick at the topsides to 0.57″ at the waterline, and 0.90″ at the keel. The deck is cored with end-grained balsa, as well as high density closed-cell foam in the deck and cabin trunk. The ballast is cast iron and is encapsulated in GRP, though one boat at least was built with lead ballast.

Under Sail

The boat has a wonderful feel at the helm and is a fun to sail, especially as the breeze picks up. Some owners have even raced their Baba 40s against modern fin keel competitors successfully. As a testament to the boat’s speed, Michael and Elizabeth Kramer in S.V. Cambria covered 396 miles in a 46 hour passage down the Sea of Cortez broad reaching in 35 knots of wind; an impressive average of 8.6 knots.

Owners often describe their Baba’s to have a feel of solidity. In heavy weather conditions the Baba 40 has the capacity to keep sailing when many other boats are heaving-to. Of note is Jeff Hartjoy’s solo passage from Peru to Buenos Aires via Cape Horn in 2009 where he experienced an immense amount of bad weather. On that passage he reported a lot of breakages but commented about the soundness of his boat.

Buyers Notes

As with many boats older than 25 years, have your surveyor check items such as chainplates and areas of balsa coring for rot. The original mild steel fuel tanks have proven to be susceptible to corrosion and on most boats, these have been replaced.

Overall, the Baba 40 has aged well, a testament to its build quality. Most examples on the market tend to be in excellent condition and priced accordingly. As of 2010 asking prices are in the range of $160k-$200k USD.
