If you are in the market for an affordable day cruiser or weekend sailor then you should consider this 1979 O’Day 28. The sailboat is well-built and has a spacious interior due to its good beam. The boat will sleep up to 4 for overnighting.
The Yanmar diesel provides proficient power for motoring when not under sail.
The O’Day 28 isn’t a racer but does sail efficiently making it a great cruiser according to the seller. The boat has a 10’ 3” beam, a fin keel and the hull is fiberglass, not layered with wood for a solid hull.
Access forward is good due to a spacious side deck.
The complement of sails consists of a main, a new 135 furling genoa, a 155 genoa, and a barely used asymmetrical spinnaker.
The aft cockpit has a wheel and bench seating. The port bench opens to reveal a large storage locker with smaller locker starboard at the aft end of the cockpit.
Below decks, you’ll find a spacious interior.
The forward cabin is outfitted with a V-berth insert to produce a double berth.
The head, though small, is very functional. You’ll find a manual flush toilet and sink with a mirror.
The salon features a settee on the port and starboard side of the cabin. There is storage space behind the settees.
The galley, located aft port, contains an icebox, a deep single sink, and a microwave.
Across from the galley is a small chart table, some storage, and space for electronics.
Behind the chart table is a quarter berth.
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.
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
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.
SA/D = SA ÷ (D ÷ 64)2/3
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.
Ballast / Displacement * 100
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.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
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.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
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.
CSV = Beam ÷ ³√(D / 64)
