Seller's Description

Website: http://gulfstar4sale.webs.com/ YouTube video tour of boat: http://www.youtube.com/watch?v=9AvSsviFK8s&feature=youtu.be

FOR SALE BY OWNER - Great cruising, and spacious liveaboard sailing yacht. Sabbatical is a 1977 Gulfstar 50 center cockpit Mark II Ketch. We have been the sole owner and cruising part of the year aboard her for over 20 years, while constantly upgrading her. She is the 3 cabin model with a classic teak interior. Recent upgrades include new standing rigging, the addition of 400 watts of solar panels, new genoa, addition of Adler Barbour 12 volt refrigeration and the addition of a new bowsprit/anchor pulpit. The auxilliary diesel engine is a reliable 85 HP Perkins 4-236. We have recently sailed her offshore from Venezuela and the ABC islands back to the US and she is fully equipped for offshore sailing and already equipped for long term cruising and liveaboard. At the moment, this sailboat is located in Ft. Lauderdale. We will be temporarily aboard during April and scheduling showings during that time. Asking price has been reduced to $99,500 during this time and we will consider all serious offers for a quick sale while we are at the boat. If interested, please contact us by email at alhnelson@aol.com. You can also contact us by phone before April 8th at (303)258-3745.

Calculations

Hull Speed
9.3 kn
Classic: 8.44 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

9.34 knots
Classic formula: 8.44 knots
Sail Area/Displacement
13.4
<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.
13.4
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
30.0
<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

30.0
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
250.4
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
250.38
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
38.5
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
38.51
<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
1.67
<2: better suited for ocean passages
>2: better suited for coastal cruising
