Seller's Description

1958 Wirth Munroe Cutter Pirouettes History:This vintage beauty, Pirouette, has been lovingly refitted. She is a true classic and shes ready to set sail!

Pirouette is looking for new owners to enjoy her as a cruiser-racer. She would also be the perfect yacht for island hopping cruisers wishing to explore, enjoying sunsets and cocktails from her deck during their Caribbean adventure. She is priced to sell and her quality build will truly stand out amongst all that plastic out there!

Her beginnings were with the Munroe family of Coconut Grove Florida. Her original build plans, photos of her restoration in 2012, and all her records come with the boat. She was originally strip plank built by Miami Shipbuilding Co., (PT boat builders), bead and cove 1.75” x 2” mahogany glued and bronze nailed. Originally, she had polyester skin but now has new modern epoxy skin. Her Swing centerboard and long overhangs distinguish her as a fast classic and her brightwork (epoxy glued mahogany on cabin sides and transom) are reminders of a bygone era. The current owner, a boat builder himself, has lovingly given her all the attention to detail she deserves, right down to modern Awlwood MA finishes. She has been boat builder owned for the past 20 years. Pirouettes layout includes a Captains bunk midship, V-berth forward, and settee that can convert to a large bed. She is able to sleep 6 comfortably. The Galley along starboard side is followed by a quarter berth if needed. To the opposite side aft is the head. Two steps down into her cabin makes her interior a breeze to access. She has a low, dry cockpit and a clipper bow with trail boards. Two bronze ballerinas dance at each side of her hull at the bow sprit.

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
