1978 Universal 41 Perry

Listed
Expired
$18,750 USD

Seller's Description

Built in the Universal Marine Ltd yard in Taiwan, the Perry 41, as she’s known, is a heavy cruising fiberglass sloop that needs to be brought back to her original glory.

The Forward Cabin is enclosed with a V-berth that comfortably sleeps two and a Hanging locker.

Just outside of the forward cabin is a private enclosed shower for convenience. The enclosed head with vanity, electric toilet, and holding tank are aft.

The main salon has two built-in lounges that both convert to sleeping berths. And, in between the lounges is a varnished drop leaf dining table that opens to seat four.

The Galley is well laid out with a 3 Burner Stove w/Oven, top Loading Refrigeration Unit (Adler-Barbour), pressurized fresh water system, water heater, and Double Stainless steel sink.

Opposite the Galley, there is another enclosed private cabin that sleeps two.

The interior is all teak and has been highly varnished, along with the teak cabin sole, which is also varnished.

Up on deck, in the cockpit, there are two large seats that seat 6 and a built-in pedestal steering station that houses the electronics, including a Raymarine C-80 Chartplotter, Signet 1500 Wind-speed, Signet 2000 Knot-meter, and Signet 1000 Depth-Meter.

There are 3-lockers under the seats. She has wide walk-around decks with plenty of room to handle the sails.

Calculations

Hull Speed
8.7 kn
Classic: 8.12 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

8.72 knots
Classic formula: 8.12 knots
Sail Area/Displacement
14.5
<16: under powered

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.
14.52
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
39.5
<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

39.47
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
275.0
275-350: heavy

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
275.0
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
36.5
30-40: moderate bluewater cruising 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
36.54
<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
1.7
<2.0: better suited for ocean passages

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
1.74
<2: better suited for ocean passages
>2: better suited for coastal cruising
