Seller's Description

Corroboree is a professionally commissioned custom sailboat, designed by Eric Sponberg and built by Lloyd Stevenson Yachts of Auckland, New Zealand. Corroboree, which is named from an Aboriginal word for “party” or “celebration”, has completed over 32,000 sea miles. A defining feature of Corroboree is the choice of wood, namely Western Red Cedar and Kauri. Kauri is a rare species of pine indigenous to New Zealand. This gives Corroboree a beautiful internal finish demonstrating true craftsmanship and quality materials, and setting Corroboree apart from other custom and production sailboats. For the size of boat, the headroom throughout the interior, coupled with the fine wood finishings, create a pleasing internal ambiance in this 2 cabin, 1 head cruiser.

The second defining feature is Corroboree’s carbon-fiber free-standing mast, which was designed by Eric Sponberg, a former Chief Engineer at Tillotson-Pearson Inc, the original builders of Freedom Yachts. Eric Sponberg was instrumental in the development of Freedom Yachts’ carbon fiber masts. Both Corroboree and the Freedom 36 have freestanding masts in the sloop configuration on a hull with a raked stem, Corroboree having a scoop stern. The mast on Corroboree was built by PLP Composite Technologies in New Hampshire. Other similarities in design include the fin keel and separate rudder, with Corroboree sporting a rudder mounted on a substantial skeg built integral to the hull.

Corroboree was originally built in New Zealand. Her first owner shipped her to Michigan where she was sailed on the Great Lakes for 27 years. Corroboree was ideally suited to these waters, as some boaters would find the absence of roller furling more challenging for single handed sailing offshore. After 27 years of ownership, Corroboree was sold to her designer, Eric Sponberg, who has since circumnavigated the globe over 6 1/2 years.

The General Arrangement of Corroboree is as follows:

Forward Cabin: Full-width V-berth (modified from original layout), shelves & lockers port, hanging locker stbd.

Equipment: EPIRB, ACR GlobalFix Pro 406 MHz GPS 6 x Life Jackets, 4 x Type I and 2 x Type III Lifesling, throwable horseshoe flotation device, with lifting tackle Air horn Distress Signals kit (flares, smokes, parachutes, mirror, distress blanket) Liferaft, 4-man Viking RescYou Pro (requires servicing 2023) Fire Extinguishers: 2 x Type BC size 1 Fire Extinguisher: 1 x Halon type mounted in Engine Compartment (out of date but still in commission) Emergency tiller, stainless steel, stowed in cockpit locker Fireboy Xintex Smoke & Fire Alarm (9v dry cell battery, new Nov 2023) 2 x Safe-T-Alert CO Alarms with sealed Lithium batteries, good for 5 years from Nov. 2023

(Show to: Public) Additional Equipment Dinghy, Hypalon inflatable, Mercury Airdeck 240 with 2 oars and 1 pump (all may be replaced) Outboard, Motor, Yamaha 2 HP 2-stroke 2 x garden hoses with nozzle 1 x water filter for hoses Bulkhead mounted clock and barometer 5-part lifting tackle (approx. 250) with bosuns chair

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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.
?
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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
?
<2: better suited for ocean passages
>2: better suited for coastal cruising
