Seller's Description

I have worked very hard rebuilding this wonderful Cruiser/live-aboard sailboat for 5 plus years. 2 New 8D 200amp batteries- May 2023! Complete systems rebuilds include wiring; plumbing; fuel; propane; rigging; steering and safety equipment; thru hulls; mast support etc have all be meticulously rebuilt and installed. Saorsa is a solid and spacious old girl with too any upgrades and improvements to mention here. She has been sailed from Maine to the FL Keys and back again and performed admirably and reliably. She has many years of life left to give the right blue water enthusiast or live aboard alike. Original or previously replaced equipment was inspected cleaned and tested to ensure safe and reliable operation. Invoices on larger upgrades and items such as rigging or the engine rebuild are available. Manuals and other detailed information is also available. As a reasonable buyer might expect, she will need work to make her your own and to finish cosmetic improvements, but for a 47 year old sailboat she is ready to sail to destinations near or far! Saorsa is currently located in Edgewater MD on the hard and listed with a broker Contact Greg @ http://www.grabbagsailboats.com”>www.grabbagsailboats.com Launch is included. Or Please Contact Neil @ 603-436-0865 or at ntphoto61@gmail.com for additional details. Seller is motivated and offers are gladly accepted!

Calculations

Hull Speed
8.3 kn
Classic: 7.94 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

8.3 knots
Classic formula: 7.94 knots
Sail Area/Displacement
15.2
<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.
15.24
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
41.4
>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

41.38
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
300.1
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
300.09
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
38.1
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
38.07
<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
1.73
<2: better suited for ocean passages
>2: better suited for coastal cruising
