Seller's Description

The interior is in good condition.

With minor work you could be sailing tomorrow!

O’Day sailboats are well made, great for sailing and light on brightwork maintenance requirements, and this 1984 28 is no exception.

Designed by C. Raymond Hunt this 28-foot sailboat is made for roominess and style. Its layout is classically symmetrical. The cabin can hold six people comfortably. The cockpit can easily hold that many or more.

The O’day 28’s forgiving nature and easy stability make this boat for sailors new to boat ownership or the more experienced, an easy choice.

The cockpit has cushions, on the back and both sides with cup holders by the wheel. and GPS and compass at the helm.

The galley has a sink, a two-burner alcohol stove. butcher block countertops, and a large ice bucket area under counter. There is plenty of storage above the counter.

The O’Day has an aft sleeping area that also has an access door to the engine compartment. A more open second engine access area is easily accessible underneath stairs.

The fore V-berth has ample sleeping space for two with padded walls and storage underneath and a wardrobe closet and drawers across from head and has a door for privacy.

The head is port side midships and has toilet, sink with a door for privacy.

Plenty of storage throughout with cubby holes and storage lockers.

Reason for selling, buying a bigger boat.

Equipment: The hull was painted in 2022 and is good shape, the deck is firm with minor spider cracks. The wooden brightwork needs a seasonal surfacing. There is no evidence of water infiltration around portholes or through bolts. The diesel engine needs replacement, however there is a brand new (2022) 9.9 hp Honda motor with a 25” long shaft with less than 12 hours (cost $3,500) that moves the boat at hull speed with only 3/4 throttle. New (2021) 120 Genoa rolling furling (Cost $2,200) Main sail was professionally washed and repaired in 2021 (cost $350) New running rigging 2022 (Cost $500) New bilge pump (cost $125) 2 new deep cell batteries (cost $250) New Head (Cost $200) New Edison Steering cable (cost $450)

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
