MurDina A Rare & Beautiful CSY 44 Walk-Thru Cutter Ketch
Named MurDina, meaning Sea Traveller, this rare CSY 44 Walk-Thru Cutter Ketch is a true bluewater cruisercustom-built, never chartered, and ready for adventure. With only three owners since new and under the current owners care since 2008, she has been meticulously maintained and thoughtfully upgraded for both performance and live aboard comfort. Since 2008, MurDina has sailed from Canada down the Eastern Seaboard, explored Cuba, and cruised extensively throughout the Caribbean. She is a proven passagemakerbuilt for adventure, yet offering the comfort and security of a true home on the water. With her solid fiberglass construction, classic lines, and warm wooden interior, shes as strong as she is beautiful. For sailors seeking a well-built, ocean-ready cruiser, MurDina is ready for her next chapter. Will you be the one to write it?
What Makes the CSY 44 Walk-Thru Cutter Ketch Special?
The CSY 44 Walk-Thru is one of the most sought-after models from Caribbean Sailing Yachts (CSY), known for their incredible strength, seaworthiness, and comfortable design. Built in the late 1970s and early 1980s, these boats were originally designed for the Caribbean charter market but quickly became a favourite among serious cruisers for their rugged construction and spacious layouts.
Key Features That Make It Stand Out: ✅ Solid Fiberglass Hull No coring, just thick, hand-laid fiberglass, making it one of the most durable cruising boats ever built. ✅ Walk-Through Design Unlike the “Walk-Over” version, the Walk-Thru layout provides easy access, making movement around the boat more comfortable and safer in rough seas. ✅ Cutter-Ketch Rig Offers versatile sail options, allowing for balanced sail plans in various conditionsideal for offshore cruising. ✅ Spacious Interior The warm, handcrafted wood interior gives a classic charm while providing ample space for comfortable living aboard.

Calculations
- Hull Speed
-
8.0 kn
Classic: 8.04 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
-
13.9
<16: under powered
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
-
3.2
<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
-
354.3
300-400: heavy
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
-
47.3
40-50: heavy bluewater 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
-
1.6
<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
Notes
Shoal draft: 4.92’. Some boats were delivered with a ketch rig.
