1987 Najad Aphrodite Aphrodite 42 ketch

Seller's Description

The Aphrodite 42 is a beautiful yacht, build by Rex Marin, a sister company of the famous Swedish Najad yard. The vessel is characterized by a timeless design and a solid finish. The centre cockpit combined with the practical rigging makes it a ideal ship for blue water sailing. This excellent build yacht has two spacious cabins. The decks are spacious and well accessible. Another feature is the integrated swim platform with shower and the beautiful and ergonomic cockpit. The sprayhood with the fixed windows and the spray hood provides good shelter. Sailing with this stable and very seaworthy ship is especially a great pleasure in breezy. The engine has always had the neccesary service. Upon entering, to portside is the practical gally with all amenities such as oven two fridges. The salon amidships provides ample space and comfort and also a great atmosphere. To starboard is the chart table with all the necessary equipment and switches. The passageway to port leads to the spacious owner’s cabin in the stern. It has a privat toilet and a separate sink with shower and provides the necessary storage space. In the bow is a spacious 2-bed cabin with private head with shower facilities and a toilet. This is an ideal boat for the blue water sailor who appreciates quality and seaworthiness.

Equipment: Rigging Rigging manufacturor is Selden. Stays renewed in 2011. Checked every year and improved if nessecary. Mainsail full batten: Peter Sanders UK 2018. High aspect genua: Peter Sanders UK 2018. Mizzen: Schokker NED 2016. Genua 2 and genua 3 in good shape, year of make not known. Two front staysails, parallel, with two roll-reef systems: Furlex Hood Two outrigger booms The optimum configuration for downwind sailing! Two self tailing winches on the main mast for controlling the halyards and a free halyard for a spinnaker/code0. Four self tailing winches in the cockpit for the controll of the frontsailes, the furlexes and the travelers. 5 Halyard stoppers on the mast and 2 halyard stoppers on the reefing lines 5 Winch handles

A complete list of the equipment will be sent to you if you sent us a request with email.

Calculations

Hull Speed
8.7 kn
Classic: 7.79 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

8.69 knots
Classic formula: 7.79 knots
Sail Area/Displacement
13.8
<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.
13.81
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
41.1
>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

41.05
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
243.1
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
243.08
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
32.2
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
32.15
<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
1.8
<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
1.75
<2: better suited for ocean passages
>2: better suited for coastal cruising
