Seller's Description

1985 Catalac 34’ Catamaran

This boat has been cruising for the past 5 months, almost exclusively at anchor or on moorings. The solar panels, wind generator and water maker make this a great boat for serious cruising. But the 15’3” beam will allow it to fit in typical slips without the need for an expensive “catamaran” slip.

The vessel “Glitch” has gone on the hard today the 2nd of May 2022. Owners have decided to downgrade to a single vessel, enjoyed immensely, this 10 meter Catalac is now ready to sell.

This 34 Catalac is intended to cruise. She was built by Tom Lack at the Quay. Located at Christchurch, Dorset, England intended to be able to handle the rough waters of the North Sea, some of these catamarans have crossed the Atlantic on their own bottom. A couple or a family will find that there is plenty of comfortable room to live and cruise. The master cabin, located forward in the starboard hull has a double berth, large hanging locker, two forward facing windows. Overhead hatch with screen and lots of storage. The guest cabin is forward in the port hull. It features two single berths, a bench seat, six drawers and two lockers.

The saloon area midship has a large U-Shaped settee that will accommodate 6-8 people comfortably. There are windows on three sides that provide plenty of light.

The boat is powered by twin Yanmar 30hp diesel engines with sail drives with 3,500 hours on each engine. Electronics include: Garmin 12” chartplotter with radar, Raymarine autopilot, standard Horizon VHF radio with AIS receiver, which is interfaced with the Garmin chartplotter. Short wave radio is included, television, reverse cycle king A/C at 16000 BTU’s. The galley has a newer refrigerator/freezer, a four burner stovetop and microwave. It comes equipped with a composting head by Nature’s Head. Comes equipped with inverter charger, solar panels, wind generator with two starting batteries and four house batteries. Owner has decided to keep the dinghy for his trawler up north. Good strong dinghy davit comes with the boat. Sail drives have been overhauled in the past year. New interior cushions and pillows.

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
