Seller's Description

S/V Ibiza Moonlight is a 1987 Catalac 10M catamaran built by Tom Lack at the Quay, Christchurch, Dorset, England. Catalac’s are noted as tough strong boats designed to ride out the roughest waters of the North Sea with both safety and comfort. Catalac 10Ms are one of the best couple or small family live-aboard cruisers ever designed. While in a pinch they can sleep 8, they really are good at providing a couple or a couple with 2 children a safe and comfortable home on the water for extended periods and do so with low maintenance and operating costs.

However, the Catalac 10M was designed with cruising in mind as it features two large forward cabins, one head and this has a custom chef’s galley as it was originally designed for a couple that owned a restaurant. The Catalac 10M is a solidly built boat and this one is powered by twin Volvo Penta diesel sail drives. These boats have a very popular layout, and sailing this boat long distances single handed, won’t be an ordeal. The Catalac 10M lets you control the boat from what basically feels like your living room. The hydraulic steering system makes steering effortless. The accommodations aboard a Catalac 10M rival a 45’ monohull, and in many ways surpass it.

The salon is in the central portion of bridge deck and provides a 360 degree view of your surroundings and is nearly twice the size of a Gemini Catamaran while featuring 6 foot 2 inch headroom in most of it. The Salon table seats 6-8 people. A person who is 5 foot 10 inches tall can walk up and down the stairs from the salon standing straight up without bumping his head or hat. The salon side windows open about half way.

We are interested to sell s/v Ibiza Moonlight quickly, it requires some work if you want to make the boat perfect, however she is ready to sail any time. I will be able to show the boat in Cortez, FL (just south of the Tampa area) from January 19-24, after that upon request, possibly we will arrange somebody from marina to show.

Calculations

Hull Speed
7.5 kn
Classic: 6.96 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

7.45 knots
Classic formula: 6.96 knots
Sail Area/Displacement
18.5
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.
18.5
<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
278.9
200-300: 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
278.93
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
17.3
<20: lightweight racing 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
17.26
<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
2.6
>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
2.64
<2: better suited for ocean passages
>2: better suited for coastal cruising
