Seller's Description
1988 ODay 240 / brand new Yamaha 9.9 4-stroke
We are selling our beloved sailboat named Mizuchi (japanese water spirit) in preparation to move abroad, and we look forward to finding her a new owner that will enjoy her as much as we have!
The boat is a 1988 ODay 240 wing keel.
Outboard is a Yamaha 9.9 4-stroke purchased new in 2021. Functions perfectly, and probably has less than 8 total hrs.
Boat is in excellent overall condition, and has had extensive refitting since I bought it in 2019. Has always been stored indoors when not in the water.
Work completed since we took ownership: Replaced rudder with beautiful Ruddercraft kick-up unit Painted hull topsides with Interlux Perfection 2-part paint Painted bottom with Interlux hard bottom paint Painted deck with KiwiGrip Replaced 2 side windows Varnished all Teak Fittings Installed heavy duty Garelick lifting engine mount Installed swim platform and ladder in unique stern notch for easy swimming access Fiberglass reinforced engine bracket and bow u-bolt areas Replaced all running rigging Installed rub rails and cam cleats at cockpit winches Replaced all dock cleats with metal versions - added amidships cleats on each side with fairleads Replaced portable head with new Dometic unit Installed new Raymarine depth gauge and sender Installed new bulkhead mounted compass Serviced roller furler for jib and replaced lower trim Replaced mainsail cover Added Robship cupholders and large storage bag in cockpit
Boat comes with tandem axle trailer - I replaced the wheels and tires on this upon taking ownership. In perfectly roadworthy and safe condition. I just re-did the wiring and replaced lights with submersible LED units. Trailer has a tongue extension that makes ramp launching possible.
This is a turnkey package, and ready to go sailing! Please contact me with any specific questions, or for additional photos. Delivery negotiable based on time & mileage. I will provide a thorough orientation of launching and rig

Calculations
- Hull Speed
-
7.5 kn
Classic: 6.12 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
- Sail Area/Displacement
-
17.0
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.
- Ballast/Displacement
-
33.3
<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
- Displacement/Length
-
177.7
100-200: light
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
- Comfort Ratio
-
15.2
<20: lightweight racing 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
- Capsize Screening
-
2.2
>2.0: better suited for coastal cruising
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
Notes
Reintroduced (or similar) as O’DAY 250 in 1996.
