Seller's Description

More photos coming soon…

This 2004 Beneteau Oceanis 42CC is a rare find among center-cockpit cruisers—blending comfort, performance, and smart upgrades into a turnkey cruising package. With its shoal draft keel that is rarely seen on a 42cc, this yacht opens up anchorages that are off-limits to deeper-keeled boats, while still delivering capable offshore handling.

The thoughtful two-cabin, two-head layout makes the Oceanis 42cc ideal for couples cruising with guests or family. The owner’s suite aft features a centerline queen birth, ample storage, and a private ensuite with a separate shower, while the forward guest cabin offers its own head and comfortable V-berth. This layout provides privacy and flexibility whether you’re living aboard full-time or just out for a long passage with friends.

This boat has seen serious miles under her keel—cruising extensively from Maine to the eastern Caribbean, the Dry Tortugas, Bermuda, and the Bahamas—yet she’s clearly been cared for and continually upgraded. The recently remodeled galley brings the feel of a modern home to sea, with custom Corian countertops, a convection oven, and an induction cooktop. New salon cushions and a memory foam mattress add comfort, while the air conditioner and washing machine allow life at sea to be just as convenient as life on land—but with better views.

Systems aboard are equally impressive. With 600Ah of BattleBorn lithium batteries, over 1,000 watts of solar, and a high-output alternator, you can confidently cruise off-grid without worrying about power. The recently updated Spectra watermaker, Starlink internet, new Mantus 65lb anchor, and new sails make this boat ready to sail to beautiful remote anchorages—which is where it has spent most of it’s time in the last 6 years.

This boat has been doing serious cruising and is ready to keep going. Whether you’re planning to head offshore, explore the ICW, or live aboard in comfort, this Oceanis 42CC is set up for self-sufficiency in remote anchorages without sacrificing creature comforts.

Calculations

Hull Speed
12.0 kn
Classic: 8.66 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

12.02 knots
Classic formula: 8.66 knots
Sail Area/Displacement
20.9
>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.
20.93
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
28.1
<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

28.13
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
120.8
100-200: light

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
120.76
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
24.0
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
23.96
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
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
1.9
<2: better suited for ocean passages
>2: better suited for coastal cruising
