Seller's Description
After more than 20 years of sailing this great boat it’s time to find her a new skipper. White Squall is easily sailed by two. Fast and can be towed by my Toyota Highlander or something a bit smaller.
Equipment: Included in this package: General: Deck is solid when tapped with hammer. Aluminum mast and boom Jib sock and a spare; Spinnaker launch bag; Tool kit and Loos gauge; Spare spinnaker sheet (endless); Tack-Tic and Velocitek. Dock lines; Fire Extinguisher; Anchor; Lifeline cushions; Tiller cover; Kick-up rudder Nissan 3.5 hp Outboard with a spare carb. It looks rough but always starts and runs like a champ
Repairs and Upgrades: Upper and lower shrouds replaced 2022; Halyards Replaced 2018; Sheets Replaced 2019 Joint at top of keel box repaired with 3M 5200 in 2022. Appears to be fixed. Boom vang controls led aft Upper rudder gudgeon replaced
Sails: Main and Jib: Ullman spring 2023. Barely used. Spinnaker: Ullman spring 2019 Backup Main and Jib: Ullman Spring 2018
Racing Record: Fleet or series champion: 2011, 2012, 2021 2014 National Championship: Finished in top 1/3 of fleet
Zieman galvanized trailer: All bunks replaced in 2023. Bearings repacked in 2020 Lights work Will probably need new tires prior to a long trip.

Calculations
- Hull Speed
-
8.8 kn
Classic: 5.69 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
-
36.5
>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
-
40.9
>40: stiffer, more 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
-
84.1
<100: Ultralight
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
-
5.6
<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
-
3.1
>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
