If youve been searching for a truly capable and beautifully built cruising yacht, look no further than Barfly, a 1993 Najad 390 currently lying in Grenada, the perfect jumping off point for Caribbean adventures or long-distance bluewater sailing. Built in Sweden by the renowned Najad yard, Barfly is a prime example of the craftsmanship and seaworthiness that have made Najad one of the most respected names in offshore cruising. Known for building yachts that are not only elegant but incredibly solid and dependable, Najads are trusted by sailors around the world for their ability to handle the open ocean with grace and confidence.
The Najad 390 is a true passage maker. With her center cockpit layout, skeg-hung rudder, and long fin keel, Barfly offers exceptional stability, control, and comfort under sail. Her moderate displacement means she moves smoothly through the water, offering a reassuring and sea-kindly motion, especially important on longer passages. Whether you’re heading upwind into a stiff trade wind or ghosting along on a downwind run, this yacht is built to get you there, safely and comfortably.
On deck, Barfly features wide side decks, robust stainless hardware, and classic teak surfaces that still show the quality of her original build. The center cockpit is deep and secure, offering excellent visibility and protection, making her ideal for offshore conditions or long stays at anchor. The layout is practical, safe, and thoughtfully designed for a couple or small crew handling her short-handed.

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)
