Seller's Description

The Seller is reluctantly placing this outstanding 1982 Irwin 40 Citation on the market because of a job transfer. This vessel had been meticulously maintained and upgraded by the previous owner. The Seller has maintained this same standard of excellence over the past two years. The vessel is 408 long on deck; length at the waterline is 312; the beam is 122; draft with the center board up is 43; draft with the board down is 9. She weighs 16,890 pounds. Scheherazade is powered by a 2016 Yanmar 3JH5E producing 39 hp. The meter shows 150 hours of use on the diesel. Sail inventory includes a mainsail and furling jib renewed by Sail Care, including a new UV cover on the jib in 2018; an asymmetrical Spinnaker with dowsing sock in launching bag, purchased in 2014 and used once; Dutchman mainsail track and car system installed in 2015; Garthauer boom vang installed in 2015; Mac Pack sail cover/lazy jack system for mainsail installed in 2017; Harken MKIV furler installed in 2013; Garthauer E-Z Glide adjustable genoa car system installed in 2013.

A recent survey noted that this boat is in Good Condition with a fair market value of $50,000 and a replacement value of approximately $375,000.

Equipment: A partial list of upgrades by the previous owner include: PYI Packless Shaft Seal (2018) R&D flexible shaft coupling (2018) New Cutlass bearing (2018) Flatscreen Tv with built-in DVD player AM/FM stereo with CD player LED lights throughout the boat (interior and exterior) New Dodger with removable side panels and Bimini and attachable center panel (2018) New Winter cover made by North Shore Canvas (2018) Nauta fresh water tanks in custom cradles under settees (1) 33 gallon and (1) 52 gallon (2018) Air Silent X wind generator with on/off switch and amp output gauge mounted in cabin (2017) Yacht Thruster 300S Bow Thruster (2018) ProSport 20 battery charger for bow thruster batteries (2018) (2) Optima 34M Blue Top AGM batteries for bow thruster (2018) Webasto 9000 BTU reverse cycle air conditioning/heating system (2017) The bottom was soda blasted, faired and then coated with four coats of Interlux Interprotect 2000E, one coat of non-ablative paint as a tracer coat and two coats of Petit Hydrocoat EOC in 2016. The bottom was sanded and recoated with two coats of Petit Hydrocoat EOC in 2018.

More recent upgrades by the Seller include: Installed 260 watts of solar panels with Bluetooth solar charge controller (Victron) with excess capacity for additional panels Victron BMV712 bluetooth battery monitor Navionics charts Redport Global WIFI extender Twin Hornet 700w bilge heater Replaced most of the Marine Sanitation System hoses Installed Blue Sea Systems electrical panel Installed shower sump box Installed secondary low level bilge pump Installed bilge level alarm The boat was hauled in August 2020 at which time the bottom was painted with Petit Hydrocoat EOC, the centerboard line was replaced, the Dynaplate was replaced, new zincs were installed and repairs were made to the lower rudder bearing.

Electronics include a Standard Horizon Explorer GX1600 with Class D DCS at the Nac Station with RAM mike at the helm; B&G digital radar; B&G chart plotter on Zues 9 multi-function display with radar overlay at the helm; Garmin GPS at the Nav Station connected to the VHF radio for DCS; Standard Horizon DS100 digital depth and SL digital know/log gauges in cockpit with repeater at the Nav station. Electrical equipment includes Balmar 100 amp alternator with Balmar Max Charge MC-612 regulator; Xantrex True Charge 2 battery charger for house and starting batteries with digital readout and control mounted in the cabin; three AGM 105 AH house batteries and one AGM 75 AH starting battery; Air Silent X wind generator.

Tankage includes two aluminum LPG tanks (installed 2015); Isotemp 6 gallon water heater (2012); Nauta fresh water tanks noted above; 20 gallon holding tank.

Tender davits are mounted on the stern as is an outboard engine crane. Included is an 8 RIB with a 2020 Mercury 3.5 hp outboard.

This boat has been especially well cared for and is a tremendous value. Everything works and is as described. Given the current state of the market, this boat is expected to sell quickly.

Calculations

Hull Speed
9.0 kn
Classic: 7.73 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

9.0 knots
Classic formula: 7.73 knots
Sail Area/Displacement
18.7
16-20: good performance

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.
18.68
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
54.3
>40: stiffer, more 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

54.28
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
212.2
200-275: moderate

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
212.19
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
24.8
20-30: coastal cruiser

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
24.75
<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
2.0
>2.0: better suited for coastal cruising

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
2.01
<2: better suited for ocean passages
>2: better suited for coastal cruising
