If you are in the market for a capable and comfortable coastal cruiser, this 2002 Beneteau 393 is a must-see sailboat. The Beneteau 393 was featured in the October 2024 edition of Sailing Magazine (Used Boat Notebook page 26). Author David Liscio describes the sailing communitys take on the 393 when it first went into production in the early 2000s: It was generally agreed by potential buyers that the 393 was good looking, featured clean lines and was built to take them where they wanted to go, which primarily was safely along any coastline on long passages in relative comfort and style. The 393 build quality was noteworthy for a production boat.
Zephyr has been diligently maintained by the current owner and well equipped for safe and comfortable cruising on the Chesapeake and beyond. Notable features include a shoal draft keel (51), a reverse transom with a swim step, in-mast furling with all lines leading to the cockpit, a Yanmar 4JH3E diesel engine (56 HP), a Raymarine Axiom radar / chartplotter (with multi-function displays at the helm and nav station), Raytheon ST6001 autopilot, and Raytheon ST60 displays for wind speed / direction, depth and speed.
The Beneteau 393 has a roomy thirteen foot beam, and five hatches and a large skylight in the saloon provide exceptional ventilation and natural light. Zephyr features a two cabin, two head layout. The forward cabin has a Pullman style berth, and the aft cabin has a spacious double berth. The dinette at the U-shaped settee in the saloon can be lowered to provide an additional berth as well. There is an L-shaped galley to port compete with a refrigerator, freezer, double sink, and a four-burner stove. The refrigerator onboard Zephyr has a new compressor as well. To starboard is a well-equipped nav station with a VHF radio, Raymarine Axiom multi-function display (for the radar and chartplotter), a satellite phone, and the ships electrical panel. To schedule a showing of this beautiful coastal cruiser, please contact Grey Hobbins with Chesapeake Nautical Cruises.

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.
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
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.
SA/D = SA ÷ (D ÷ 64)2/3
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.
Ballast / Displacement * 100
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.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
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.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
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.
CSV = Beam ÷ ³√(D / 64)
Also called BENETEAU 393 and MOORINGS 403. Deep draft model: 6.25’.
