1986 Jensen Marine Cal 28

Listed
Expired
$19,000 USD

Seller's Description

Providence has a 2015 Westerbeke diesel engine with very low engine hours, spinnaker and whisker poles and a good compliment of sails. She is a performance cruiser and racer, as well as great for day sailing. Providence can be single handed, enjoyed by one couple or multiple friends. She has a portable a/c unit and an exterior propane grill. Providence is located at Nyack Boat Club and meets the requirement to be stored during the winter at NBC. This 1986 Cal 28 has an incredible, interior cubic volume, which is equivalent to the Catalina 30. The Cal 28s reputation has been built on performance, value and quality construction with an interior space that is unmatched for this size of vessel.Forward there is a roomy V-berth with an insert. Just aft is the main salon which has a straight settee to starboard and an L-shaped settee to port with a centerline dropleaf table. The galley, with stove and oven, is aft to port along with access to the aft berth. The chart table and head are aft to starboard. The head/shower compartment is aft at the beamiest part of the boat where the headroom is the greatest.

Calculations

Hull Speed
7.1 kn
Classic: 6.47 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

7.14 knots
Classic formula: 6.47 knots
Sail Area/Displacement
17.2
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.
17.21
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
39.2
<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

39.22
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
253.2
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
253.24
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
19.1
<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
19.05
<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
2.2
>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
2.21
<2: better suited for ocean passages
>2: better suited for coastal cruising

Also available with Sheel keel.
Draft: 3.67’/1.12m
Disp.: 7525 lbs.
Bal.: 3150 lbs.
