Rigging and Sails: Fractional rig, with single set of aft-swept spreaders, baby-stay, removable inner forestay, and Dyneema adjustable running backstays. All 1x19 SS rigging replaced in 2021. -100% Jib on Harken roller furler. UV cover needs a little stitching. Over 20 years old. -Zoom Code Zero on Profurl Infinity Furling system. New in 2020 -Zoom fully battened mainsail, with two boom adjusted, winch assisted reef points. New in 2020 -One new, never used hank on stay sail in bag Three cockpit winches (2 x Lewmar 46 ST & 1 x Harken 42 ST) Two mast mounted winches (2 x Harken 42 ST) Two boom mounted winches (2 x Harken 40ST) Lazy Jack system Outhaul, Block Boomvang, Cunningham, Preventers Motor: Volvo MD22P 60HP inboard diesel engine with custom exhaust elbow. 3050 hours 125A Balmar alternator with Balmar 612 Regulator ZF Hurth Transmission New SS shaft installed in 2020 Seahawk S2 Autostream feathering propellor, with SS line cutter Spare water pump, raw water pump, starter, wiring harness, alternator included Anchor & Windlass: 1 x Rocna Vulcan 70lb 1 x 45 lb CQR 1 x 25 lb Danforth 300 of 5/16 anchor chain regalvined in 2020, 200 of braided on additional rode 50 of 5/16 anchor chain with 100 of braided on rode for stern anchor Nilsson V3000 electric windlass with deck mounted switch. Brand new electric motor and gearbox gears replaced in 2023. Generator: Balmar APC 750 Diesel Generator with 210A alternator. What this is, is a two cylinder Yanmar Diesel Engine driving a Prestolite 210A alternator. The ESC (electronic speed control) does not work due to a failure in the potentiometers. Throttle is manually controlled with a cable/knob system. One Balmar 240A alternator included. At one point the water maker was engine driven by this generator, utilizing a custom mount system and belt driven clutch attached to the high pressure pump. Can be re-retrofitted if desired. Electrical: 560AH lithium battery bank installed in 2023 utilizing a 200A Overkill BMS (with spare 120A BMS). 120AH AGM starting battery with Xantrex DC to DC charger. System is wired with switchs to be able to isolate power and identify issues across the circuits. 110AC electrical panel, with shoreside power, wired to outlets, watermaker, air conditioner, hot water heater, and Starlink. 1100 Watts of solar power run to three separate Victron solar controllers (2 x 15A & 1 x 30A) Battery compartment custom cooling system. System activates fans at a specific user set temperature.

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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.
?
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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: better suited for ocean passages
>2: better suited for coastal cruising
