Susurro has been owned and operated by a USCG licensed Captain for 11 years and has been significantly restored/upgraded over the past 18 months.

This vessel sails beautifully and is designed for 15 to 20 knots of wind; she is a sturdy and spacious ship and can be sailed without crew.

Owner has two sailboats and needs to part with one.

Equipment: Repowered with Yanmar 3JH40 Common Rail diesel engine (40 HP) in April 2022; Engine hours: 5; everything from the motor to the prop has been replaced: transmission, shaft, cutlass bearing and prop (pitch adjusted to new engine); new mechanical and electronic engine controls and monitoring; new raw water strainer and secondary fuel filter.

Five sails; all in very good condition with great shape: Main, Storm Main, 101% Genoa (furling system 2012), 85% Jib (altered for furling), and Stay Sail (furling system 2022); all sails have been meticulously maintained; main sail was fully battened in 2021.

Mainsail stack pack (2016) and lazy jack system (2022).

Garmin GPS (741sx), Raymarine autopilot, Raymarine wireless anemometer, Standard Horizon GX1700 AIS VHF (All equipment is less than 10 years old).

Depth/temperature transponder replaced in 2018.

Hull, deck, mast and boom has been resurfaced with AWLGRIP; non-skid surfaces refinished; teak refinished (2022).

Bottom sanded and repainted in Fall 2021; no blisters.

Mast was stepped in April 2022 and all standing rigging inspected.

Mast and boom mounted running rigging replaced (2022); all sheets are less than 5 years old.

Electrical system has been rewired (2022); new panels, consolidation and removal of old wiring systems; wiring brought up to maritime code.

New cabin lights and wiring (2021).

Xantrex Charger/Inverter for House Batteries (2018).

Noco Genius Charger for Starter Batteries (2022).

Battery management system installed (2021).

Calculations

Hull Speed
7.2 kn
Classic: 7.22 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

7.15 knots
Classic formula: 7.22 knots
Sail Area/Displacement
16.2
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.
16.23
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
41.0
>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

41.03
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
356.8
>350: ultraheavy

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
356.84
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
35.1
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
35.08
<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
1.76
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Length incl. bowsprit: 41.75’
Available with a Cutter, Ketch or Schooner rig.
Ketch SA: 761 sq.ft.
Schooner SA: 721 sq.ft.
