Seller's Description

08/04/2020 Sold, subject to survey

We have decided to sell our beloved 1987 Irwin Citation 38. We have owned Tala Kino for the last 4 years and have invested countless hours improving her at our home dock.

Hull repainted new floors, complete engine rebuild & lots more! Decks and cockpit just repainted, all wood recoated and in excellent shape.

We bought this boat because of her sleek, good looks and frankly startling sailing performance. TK is an absolute blast under sail, she suffers from zero weather helm. This boat cruises at 7 kts consistently, we often see over 8 kts, I believe the official hull speed is 7.2 kts. There is very little out there that will be able to keep up with you! Unless it has 2 hulls of course.

She has a cool dropdown transom, with steps leading directly into the water, so is great for swimming from in the nice warm waters of Florida.

Pretty impressive accommodation for a boat built for speed. Nice size aft cabin with a small sofa, the cockpit is raised to create headroom and actually makes the cockpit a lot more comfortable.

Sleeping for 2 in the main cabin. Further double berth in the forepeak with closet, drawers and dressing area.

Top section of hull was repainted in 2019 (pic under sail is from 2017)

Mast is at 56 feet (will go under most ICW bridges which are at 65 feet)

Equipment: Helm Controls & Electronics Depth Finder Wind Speed indicator Portable VHF Cruise Air AC unit

Calculations

Hull Speed
8.4 kn
Classic: 7.42 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

8.41 knots
Classic formula: 7.42 knots
Sail Area/Displacement
17.8
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.
17.76
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
36.7
<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

36.67
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
232.0
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
231.99
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
24.2
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
24.22
<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
2.03
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Shoal draft: 4.92’
