Seller's Description

This classic William Garden ketch is like no other. In 2019, Serenade’s inboard diesel was removed and replaced with a 70hp electric motor, powered by nine 8D AGM batteries which are charged by a new 6kw Genset. This configuration provides extended range with less than half the fuel consumption of an equivalent inboard diesel, and without all the maintenance demands. Serenade also has new sails, new booms, new plumbing, and some updated wiring. She still has some cosmetic needs to take care of, but she is in good running order and is actively sailed. This is a rare opportunity to acquire a proven offshore classic with a contemporary, electric power plant.

Equipment: The cabin interior is nicely finished using an abundance of teak joinery, trim and solid doors with ornate carvings. The cabin sole is teak and holly. Ventilation is provided by large a teak butterfly hatches and a forward sliding hatch.

Starting Forward: Forepeak is currently used as a sail locker but could be retrofitted with berths. Enclosed head to port with manual toilet, vanity, and shower stall Master stateroom with double pullman berth to starboard. Main saloon with settee berths. Hand-carved doors in forward bulkhead provide privacy for the head to port and master stateroom to starboard. The large battery bank is stored beneath the cabin sole. engine box to center dinette with fore and aft seating to port, across from the galley. galley to starboard (at base of companionway steps) aft of the dinette to port is a large storage area that houses the genset. A central companionway leads abaft into the cockpit.

Galley: GalleyMaid (3) burner LPG range Single bay stainless steel sink Top-opening ice box Large amounts of storage space

Electrical Equipment: New bank of (9) 8D 12 volt AGM batteries wired in series for running the auxiliary motor (108 volts DC) New (1) 4D 12 volt sealed type battery which powers all house loads to include lighting, navigation equipment and pump systems. 30 amp shore power system 30 amp Newmar AC battery charger New Northern Lights 6kw genset, 66 hours

Propulsion System: NEW 2019 Elco model EP-70 electric motor rated @ 262 amps at 108 volts DC. The motor is rated for 50,000 hours Motor vital signs are monitored via new Elco digital gauge panel at the steering pedestal console. The motor is direct drive (no dedicated transmission or reduction gearing). The engine is controlled via a single lever control fitted at the pedestal The original fuel tank was removed and the space converted to a massive battery bank to power the motor The propellor is a fixed 18” 3-blade bronze

Electronics & Navigation: Standard Horizon Eclipse VHF radio Garmin 7607 XSV GPS/plotter 6 Danforth Constellation binnacle compass

Hull: The hull is solid fiberglass with a heavy layup. Full keel with encapsulated steel/cement ballast Topside finish is original gelcoat, structurally good but in need of cosmetics Bottom reported in good condition

Deck: The side decks and cockpit seats are faced with a teak overlay Raised bulwarks are fitted with a teak cap rail The cabin trunk has a large teak butterfly hatch over the main saloon and a forward companionway hatch. There is a large raised fixed port on the fordeck.

Deck Equipment: Ground Tackle: 30 lb. Danforth and 45 lb. CQR; Maxwell electric windlass (to be confirmed) Bowsprit with pulpit and Sampson Posts on the foredeck. dinghy davits

Rigging: Masthead ketch rig, keel stepped. Spars consist of spruce box-section hollow masts and booms (new booms 2019). Masts were inspected, repaired, and painted in 2019. 1x19 Stainless Steel wire rigging, reported as recent but exact age is unknown

Sails: All sails are new (2019), dacron, by Downs Sails partially battened mainsail. 130 genoa on a harken jib furler working jib partially battened mizzen.

Calculations

Hull Speed
7.4 kn
Classic: 7.58 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

7.35 knots
Classic formula: 7.58 knots
Sail Area/Displacement
13.5
<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.
13.53
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
32.9
<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

32.86
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
381.9
>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
381.9
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
44.4
40-50: heavy bluewater 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
44.42
<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
1.6
<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
1.6
<2: better suited for ocean passages
>2: better suited for coastal cruising
