Listed
$13,500 USD

Seller's Description

This boats name is Azul! Ive spent the last 7 years outfitting this boat for cruising the sea of Cortez. Its an excellent boat for a couple. Its not huge but has excellent bones. Clean. New cushions. A lot of the interior has been redone in the last 7 years including the galley. American flagged vessel . Motivated to sell, but I really want this to go to someone who is going to sail this boat through the sea of Cortez or across oceans. Perfect for someone who wants to learn. This boat was the first boat I ever owned and i learned! So can you !!!! Seize the day!

Equipment: New- Brand New Lewmar windlass Entire boat was rewired last year- with new wire, all new Victron electronics ( renogy 700w inverter, battery monitor , solar mppt charge controller,) New batteries x4 6 volt -2 years old 200w solar thats was just installed last season Boss audio surround sound system bRAND New tiller handle Brand new used once to calibrate- raymarine st2000 electronic autopilot New salt water foot pump for the galley

Used- old Yanmar 1gm that was recently serviced and still runs great. Dometic Freezer fridge combo with custom fiberglass case to insulate. Running rigging was all replaced a few years back. Navigation electronics are in good shape.

Calculations

Hull Speed
7.3 kn
Classic: 6.64 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

7.27 knots
Classic formula: 6.64 knots
Sail Area/Displacement
17.0
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.
17.0
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
40.7
>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

40.71
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
258.7
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
258.74
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
23.4
20-30: coastal cruiser

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
23.44
<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
2.0
<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
1.95
<2: better suited for ocean passages
>2: better suited for coastal cruising
