Seller's Description
Legendary sailboat originally built 1973 in Kent, WA, fully restored in 2010 and well maintained since then. The Kent Ranger 20 is a popular boat and has a very proud fanbase. Only 600 were built over a span of 13 years. This is #153.
Ideal for inner bay family day sails like the SF Bay area. Its got a roomy cockpit with plenty of space for 4. It features an innovative fixed cuddy (cabin) with inbuilt storage bin seats. Perfect for wary family members to enjoy some wind protection while still being in on the action. Theres a cushioned seating/sleeping area and even a built in picnic table to lift up.
Shes very balanced on the helm, responsive, yet forgiving and I think its a fantastic trainer for sailing beginners. Completely dry in 15 knots nose wind and she can be sailed single handedly.
Hull and top is of outstanding quality, solid fiberglass-reinforced plastic throughout, completely repainted, new cushions plus new rigging - all in 2010. Shes got the original Evinrude 6 2-stroke engine which still works like charm. New bottom paint late 2018 by KKMI.
She comes with a newer main sail #40, original jib, genoa, a-sail (asymmetric spinnaker), anchor, custom covers for all teak details, plus other accessories. Connect a standard car battery and youll have cabin/anchor/runnings lights, speedometer, depth sounder and even a bilge pump.
Showings available from June 10th.
If you live in the North Bay: Shes currently berthed (docked) at a very attractive $250/month in Strawberry (near Tiburon) at Richardson Bay. It’s a fantastic sailing ground with predictable winds and top-notch views on SF, Alcatraz and Golden Gate. Lease transfer is available if you want to keep her at this location.
If you want to haul her away: The Kent Ranger 20 is a mid-size trailer sailer. Its easy to set-up/rig especially because the mast raises aft (from the front towards the back), so shrouds and forestay can be left attached. No trailer is provided but youll find many trailer models which will fit.

Calculations
- Hull Speed

6.8 kn
Classic: 5.36 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

23.3
>20: high performance
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
-
36.6
<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
-
163.1
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
-
8.6
<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
-
2.8
>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
