Seller's Description

1983 Concordia 33 Custom built sailboat designed by John Kiley $10,900 or Best Offer

99 PHRF handicap on Lake Ontario

Overview: The Concordia 33, “Revenant” (formerly Impression), is a 1983 design by John Kiley. Kiley, an associate from C. Raymond Hunt. Kiley was a part of the design team that drew the lines for Cals and Pearsons in the 1980s.The boat is a one-off custom build by Concordia Custom Yachts of Dartmouth, MA, built for the original owners - Kiley and Brody MacGregor, President of Concordia. The boat was the second boat produced by the company and was constructed on a male mold, incorporating foam core in the build of the hull, deck, and bulkheads. The designer indicated that the IOR rule was not a factor in the design. The boat was designed, built, moored, and raced in Dartmouth, MA throughout its entire lifetime until January of 2019. Boat was raced in the 1990 Newport to Bermuda Race, Block Island, and numerous regattas on Buzzards Bay from 1983 - 2008. Boat raced in local club races on Lake Ontario in 2019, 2021, and 2022.

Paint: Deck was painted (white and gray) by the previous owner and is in good shape. Hull was professionally spray painted in 2020 - navy blue. Custom Concordia cove stripe with star and crescent moon professionally painted by a pin-striper/painter. New graphics in 2020. Bottom - burnished VC 17

Equipment: Equipment: Rigged and ready to race, cruise, daysail - headfoil - rigid vang - Forte carbon fiber symmetrical spinnaker pole - 10% overlength - lots of Harken and upgraded gear - 6 winches (Newer Harken 2 speed primaries) - course and fine mainsheet - split backstay adjustment (12:1) - windex - 2 analog bulkhead mounted compasses - VHF radio - 3 fenders, 5 docklines

Safety: flares, 6 lifejackets, horseshoe buoy, lifesling, throw rope

Sails: 2008 Light #1 - Quantum 2008 Heavy #1 - Quantum 2008 Mainsail - Quantum 2008 Blade - Quantum 2008 AP Spinnaker (white)- Quantum All 2008 sails were virtually new in 2019 Many additional older sails - 3 spinnakers and many others

Accommodations: Potential to sleep 8 - 2 quarter berths, 2 settee berths, 2 pilot berths, vee berth. Boat currently lacks a head and has a partial galley. Nav station with seat.

Rig: Hall Spars - Keel-stepped tapered fractional rig with double spreaders and jumper struts, internal halyards, runners and checks. Rod rigging - backstay is rope.

Power: 1 cylinder Yanmar 1 GM diesel - 6 hp. Engine will push the boat up to hull speed and has plenty of power for choppy/wavy/windy conditions. Engine is coupled with a saildive with 2 blade folding prop.

Storage/Launch: Indoor off-season storage for at least the past 13 years. Boat is located at Lake Breeze Marina in Kent NY with all yard fees up-to-date and spring launch paid for. Boat includes eight jackstands

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
