Seller's Description
This desirable Cal 33 was converted by the current owner to use a modern, environmentally friendly, inboard electric motor.
She will make a wonderful liveaboard or starter boat. This is a perfect opportunity for someone who is looking to own a safe and affordable home that can easily move between marinas as needed for aviation professionals, tech workers, college students, etc.
During the boat’s last haul-out, the current owner refreshed it with modern NEMA 2000 Garmin branded navigation instrumentation, which includes:
– GMI 20 digital marine instrument display – GWS 10 wind speed / direction sensor – DST800 thru-hull water depth / speed / temperature sensor – GPS 19x position / heading sensor
An iPad/iPhone can also connect to the boat via wifi to pull data from the navigation instruments, which enables electronic navigational charting using the iNavX app.
This boat is ready for short coastal sailing excursions and day trips, but if the future owner plans to regularly take it out on long distance, multi-day voyages then new sails would be ideal.
The Mars ME 0913 10.5kw electric motor, with 48v Sevcon Gen-4 450amp controller, is currently powered by a 100ah 48v AGM battery plant. A future owner may want to consider upgrading batteries to superior lithium ion technology.
She has recently been refreshed with new settee covers throughout and will sleep up to two people in the V-berth.The boat also comes equipped with:
– Flat screen TV – Refrigerator – Electric Water Heater – Pressurized Water System – Automatic Flush Toilet – Propane Powered Oven/Stovetop
The current owner is very knowledgeable about the various systems on board, and is happy to answer any questions about its current state, as well as any potential future upgrades with interested buyers.

Calculations
- Hull Speed
-
8.0 kn
Classic: 7.03 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
-
17.6
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
-
44.4
>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
-
232.0
200-300: moderate
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
-
25.4
20-30: coastal cruiser
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
-
1.9
<2.0: better suited for ocean passages
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
